An architect who mixes water and nature to build resilience

An architect who mixes water and nature to build resilience

Kotchakorn Voraakhom, 43, is a Thai landscape architect whose firm, Landprocess, focuses on social and environmental transformation through projects like canal gardens, water-storing parks and rooftop farms.

 

You grew up in Bangkok, received your master’s degree from the Harvard Graduate School of Design and worked for landscape architecture firms in the United States before returning to Bangkok and starting your own firm. Your work combines both international and local perspectives. What is the advantage of this approach?

Responding to climate change is not something generic. We need to tailor each solution to a culture and a setting. Here in Thailand it is about drought and flood. This is not about melting ice. There are flash floods, and floods that come to stay. There are different patterns of nature. And they’re different than they used to be. We need to adapt.

 

Your designs explore both landscape and water. Can you talk about your connection to both?

I still remember sneaking into the canals as a child and seeing the greenery along them. Already there was less and less nature around them, but it was such a healing moment for me. My house was a rowhouse along the main road. We had no backyard, just the street. The only walks you could do were very hot, very dangerous and very polluted.

Bangkok is built on wetlands and prone to heavy rains. What can be done about the frequent flooding?

When my firm builds parks, we’re accepting that they will flood. Right now, when we build for floods in Thailand, we see it with fear. We’re building dams higher and higher. That’s how you often deal with uncertainty — with fear. You need to deal with uncertainty with flexibility, with understanding. It’s OK to flood, and it’s OK to be “weak.” That means resilience. With that mind-set, you create designs that talk with nature. That dance with nature. It’s very Buddhist — accepting the world as it is.

 

Your firm’s first major project was Chulalongkorn University Centenary Park, in the center of Bangkok, which you completed in 2017. Can you talk about that design and how it helps address flooding, overdevelopment and a lack of public space?

It was the first major park in the city in 30 years, and the university built it to celebrate its 100th anniversary. We said it’s not just about celebrating what’s been, but about helping the city and its citizens survive and thrive in the next 100 years. So, let’s try to define a new way of working with water and living in the city.

The whole park is inclined to collect water. On one end you have a series of sloping buildings containing museums, cafes, parking spaces and other functions, which we equipped with a green roof. Three underground tanks store the rainwater absorbed by the roof. The land slopes down from there to a main lawn and a series of wetlands and then continues down to a retention pond. When it rains, excess water from the green roof is filtered by the wetland, then it flows into the retention pond, which can double in size.

The concept comes partly from the idea of monkey cheeks. Our previous king [Bhumibol Adulyadej] saw that a monkey stores his food in his cheeks and then eats it when he’s hungry. This is a kind of monkey cheek for water in the city.

This seems like a good example of how you work. You tend to push the boundaries of ideas that are already themselves pushing boundaries.

There are so many things to address when you talk about public space. So if you have one chance, you want to address several problems. I don’t think one design can serve just one client. It needs to serve the whole city, the whole population, and the whole ecosystem. Design is having unexpected clients — the birds and the bees. You’re serving clients well beyond the ones that pay you.

 

What are the biggest challenges you face in achieving this?

Change has happened so quickly here that it’s been hard to adapt. Not long ago there were ancient towns and rice fields. Then, boom, concrete, big buildings. All this density has happened in the last 50 years. The speed of change has been too fast, and much of the response has come without direction. That’s why we need professions like urban planning and landscape architecture.

 

You co-founded the Porous City Network, which addresses ways to naturally reduce the impacts of flooding in Southeast Asia. Explain this effort and its challenges.

Many people don’t understand what we’re proposing if they’re not trained as architects or engineers. They think if you just build walls and dams that’s the best solution. Being designers, we have powerful tools to create images and animations, to show them what the reality will be — the impacts of big walls that they’ll have to live with forever. Do you really want that when it only floods five days per year? We work to convince them there is another way.

 

What are some of the challenges of being a female designer in Thailand?

My identity is confusing. In Thai culture I’m a little bit American, and in American culture I’m very Thai. I don’t want gender to be another burden.

There are many benefits to being a woman; particularly the connection to nature. I think with motherhood, the cycles of the body, we’re more in touch with nature in our bodies and our hearts.

Another benefit of being a woman is that I don’t feel afraid to lose face, and I feel more flexible because of that. Male stereotypes are so strong. For women, there are fewer expectations; you can do whatever you want. You can be yourself.

175 countries agree to first-of-its-kind plastic waste treaty

175 countries agree to first-of-its-kind plastic waste treaty

The world has taken its biggest step yet to curb the plastic pollution crisis.

The United Nations said Wednesday that representatives of 175 countries have agreed to develop a first-of-its-kind global treaty to restrict plastic waste. The resolution followed negotiations over the past week at the fifth session of the U.N. Environment Assembly in Nairobi, Kenya.

The treaty aims to tackle one of the most pressing environmental issues the world faces. The sheer pervasiveness of plastic waste has been widely recognized in recent years, with plastic debris identified everywhere from Arctic snow to the bottom of the Mariana Trench, the deepest point in the ocean. Microplastics, tiny pieces of the material, have also been found in the digestive tracts of a range of species, from fish to seabirds, and even humans.

The U.N. said member states agreed to begin crafting a legally binding international agreement that addresses the “full lifecycle of plastic,” from its production to its disposal.

Inger Andersen, the executive director of the U.N. Environment Program, called the resolution, “the most significant environmental multilateral deal” since the Paris Agreement, a landmark accord signed by 196 countries in 2015 that aims to limit global warming to below 1.5 degrees Celsius.

“Today marks a triumph by planet earth over single-use plastics,” Andersen said in a statement. “It is an insurance policy for this generation and future ones, so they may live with plastic and not be doomed by it.”

The proliferation of plastic has grown astronomically, from more than 2 million tons produced in 1950 to nearly 400 million tons produced in 2017, according to the U.N.

More than 12 million tons of plastic waste flow into the world’s oceans each year, the intergovernmental organization said, adding that that figure could triple by 2040.

A 2021 assessment by the U.N. Environment Program estimated that less than 10 percent of the world’s plastic has been recycled.

“Plastic pollution has grown into an epidemic,” Espen Barth Eide, president of the U.N. Environment Assembly’s fifth session and Norway’s minister for climate and the environment, said in a statement. “With today’s resolution we are officially on track for a cure.”

Barth Eide acknowledged that the resolution occurred against the backdrop of Russia’s invasion of Ukraine, saying it “shows multilateral cooperation at its best.”

The U.N. said the treaty will not only curb the amount of plastic pollution, but will also reduce greenhouse gas emissions associated with producing the material, since plastics are made from fossil fuels.

Nik Sekhran, chief conservation officer at the World Wildlife Fund, applauded the development and called it a “historic agreement.”

“As we strive toward securing a healthier future for people and the planet, today’s decision sets us on an ambitious mission to solve our plastic pollution crisis and to achieve a strong circular economy,” he said in a statement.

World leaders will now have until the end of 2024 to craft the treaty, including settling details on funding and collaboration.

Rising petrol prices fuel interest in EVs

Rising petrol prices fuel interest in EVs

Petrol prices racing towards $4 a litre has further enlivened Kiwi interest in new electric cars, but those taking the plunge are much more likely to find themselves on a waiting list than in a vehicle.

That feedback comes from the motor industry, which says the latest influence on pain at the pump, Russia’s conflict with Ukraine, could well inflict more than the punishing oil prices hitting Kiwi motorists’ pockets now.

David Crawford, chief executive of the Motor Industry Association which represents almost all new vehicle distributors, is concerned the invasion has exacerbated supply chain crunches already so disrupted some national distributors have ceased taking forward orders.

 

David Crawford, chief executive of the Motor Industry Association.

 

“Fuel prices were going up already, but they have spiked because of the Russia-Ukraine conflict.There is no doubt that heightened fuel price has increased the number of enquiries about (these) low emission vehicles. I am receiving that feedback from distributors.”

Whether distributors can meet this demand is far from clear. His feel is that few, if any, are in that position. The war is a blow to an industry already feeling stress from almost all new vehicles being subject to stock issues.

Franchises’ ability to supply new products has been steadily lessening for some time, but potential a new buyer having to wait at least a few months or perhaps more than a year for their vehicle has likely elevated even more now.

“Constraining that (demand) is disruption around availability of vehicles.”

Crawford says Russia and Ukraine manufacture semiconductors, vital to modern cars and already in short supply before Russia kicked off its incursion on February 24. Ukraine is a big supplier of car components, mainly to European makers. Russia supplies rare earth and precious metals.

The semiconductor crisis has already evidenced here with de-contenting of some popular cars. One example is the new petrol Mitsubishi Outlander. It launched late last year with a digital dashboard, but that only featured on the first shipment of 100 cars. It then regressed to an analogue display.

Electrified cars – whether in wholly electric or plug-in and hybrid forms – are especially reliant on semiconductors, Crawford says.

 

The Mitsubishi Outlander has been a victim of the semiconductor shortage.

 

“Electric vehicles have a high number of chips. We already had a processing chip shortage in vehicles and this (conflict) has only made it worse.

“Historically every time fuel price increases by more than 50 cents a litre, and stays up, buying patterns change and people look for more fuel efficiency,” he says.

“Fifteen years ago that was smaller cars with smaller engines. These days they are looking at electric vehicles, PHEVs and hybrids.”

Government’s Clean Car rebate that discounted $8625 from the price of a new full electric with a recommended retail under $80,000, and lesser amounts from PHEVs below that ceiling (with hybrids due to benefit from April 1) has already clearly fed electric interest at new car level, but often the point where it far exceeds national allocations. There’s no solution to that.

“Some brands have stopped taking orders for some really popular models because wait lists are nine to 12 months out.

“It’s a common factor for EVs and PHEVs. The challenge is being able to get enough here to satisfy demand. People are going to have to be patient.”

 

The Clean Car Programme has also driven interest in EVs, PHEVs and hybrids. WAKA KOTAHI

 

Crawford wouldn’t like to forecast how long this scenario might stretch out.

“The longer that drags out the longer it’ll take to adjust… I’m not prepared to make a prediction about how long that conflict will last. A Westernised Ukraine is clearly untenable to Russia.”

Mark Gilbert, chairman of Drive Electric, a high-profile not-for-profit EV advocacy group, concurs with Crawford’s views.

A former car industry chief executive (he ran BMW New Zealand from 2004 to 2012), Gilbert believes more EVs will be registered here this year than in 2021, in itself a record period, with 13,247 new and ex-overseas’ used registrations, but only because of already cemented forward planning by companies.

“Most car companies would have been planning for more EVs in 2022 than they were in 2021, I feel confident in saying by the end of this year we will see more EVs sold in 2022 than last year.

“In January and February the combined uptake (of EVs) was 2500 vehicles so, if that trend continues, we are conceivably looking at 15,000 for the year.”

Yet the next two to three months “will be very interesting,” he said, adding that with the conflict, the microchip shortage and shipping issues “It’s a bit of a nightmare to forecast.”

With just under 40,000 electric vehicles in circulation overall, the sector is building off a low base, he says.

Crawford has suggested anyone seeking to step out of a vehicle that is becoming too expensive to run might, in some circumstances, simply be better off forgetting about buying into anything new at all.

However, those involved in that trade don’t see ex-Japan used stock being necessarily available in abundance to fulfil that.

David Vinsen, chief executive of the Vehicle Importers Association, the industry body for the used import trade, says as much as his members will likely focus more on sourcing efficient vehicles, this is a finite source.

New Zealand traders are competing with other countries, including Australia, to secure EV stock and, while it sounded facile to say it, “they (the Japanese car market) are not making any more five-year old cars.”

The VIA has just secured victory in its fight to achieve a 25 percent reduction in penalties against used vehicles that introduce when the Clean Car legislation enacts on April 1.

The association had originally expected penalties to be around half of those of new vehicles, acknowledging the shorter time used cars spend on the fleet, but instead the calculator issued by the Ministry of Transport showed they were the same.

Even with that impact halved, the VIA believes Clean Car will, at least for the foreseeable future, lead to increased prices and decreased options for car buyers.

Vinsen, who is on a Government-established low emission vehicle working group, is concerned the formula for Government’s emissions reduction actions still isn’t right.

He says the effect of the Clean Car discount on used import candidate vehicles has been that prices in Japan have climbed. “It has been an immediate wealth transfer from New Zealand to Japan.

“The price of petrol will increase demand for efficient vehicles, including EVs, which is what we have been advocating all along.

“If the Government was serious about driving the demand for fuel efficient vehicles and EVs they would do it through the Emissions Trading Scheme and put a proper carbon tax on petrol, let the user pay and let the demand fall where it should.

“Instead they won’t deal with the substantive issue. The Clean Car Standard and the Clean Car discount are only superficial exercises to make it appear the Government is doing something. What’s going to happen in two, three, five years’ time? They are going to look back and think ‘why on Earth isn’t this working?’

“We are bringing in every EV we can get our hands on and our colleagues in the new industry are doing the same. But there are finite supplies… with the pool of used cars internationally, but particularly in Japan, what is there is there.

“All it’s going to do is put the price of vehicles up.”

Gilbert, meanwhile, wonders how influential China might become.

He points out that Shanghai-based BYD, primarily a producer of budget fully electric models, has just announced intent to start selling in Australia. Even though the distributor also has rights to NZ, it’s not clear when the brand will start up here.

Yet China is a juggernaut, being the world’s top EV market and also the global leader in production.

“You have a lot of brands in China – they seem to be rolling out a new one every week,” says Gilbert.

“Even though not many are building in right-hand drive, if they don’t have the same supply chain issues, there is perhaps an opportunity.”

Regardless of how hard it might be to secure an electric car, those who already own one will be relieved to escape paying so much for petrol.

His own car, a premium sector Audi e-tron SUV, is proving increasingly cost-effective.

“It’s basically costing the equivalent of 30 cents a litre to fill. Putting in fuel that’s costing 10 times that has got to be making people think.”

Solar panel add-on pulls water from air without consuming electricity

Solar panel add-on pulls water from air without consuming electricity

A three-month trial in Saudi Arabia has shown that a solar panel add-on system can harvest water without using any electricity by exploiting the day-night warming and cooling of solar panels. In fact, the system slightly increases the electricity-generating efficiency of the panels by keeping them cooler.

“I am confident that the system can be manufactured economically,” says Peng Wang at the country’s King Abdullah University of Science and Technology. “We are looking forward to working with potential industrial partners to speed up this process.”

The new approach uses a layer of hydrogel placed under each photovoltaic panel and encased in a metal box. During the night, the box is open to allow the desert air to flow through it where the hydrogel absorbs water vapour.

During the day, the box is closed. The sun warms the solar panel, and thus also the hydrogel underneath it, making the water evaporate from the gel. The humidity in the closed box gets so high that the water condenses on the metal and can be drained from the box.

During the trial, from May to June 2021, a small prototype system produced 0.6 litres of water per square metre of solar panel per day.

The basic idea isn’t new. Several other teams have developed water harvesters that also exploit day-night temperature changes. But Wang says his team is the first to create an integrated system that extracts water while also generating electricity.

One advantage of using the add-on is that no extra land is required. Another is that electricity generation increased slightly – by nearly 2 per cent – because the transfer of heat to the hydrogel and water-harvesting box cools the solar panels. High temperatures reduce the efficiency of solar panels.

The cooling effect can be increased by leaving the condensation box open during the day. Although this stops water extraction, in the trial it boosted electricity generation by up to 10 per cent. Wang envisages creating flexible systems that could switch between water extraction and higher solar panel electricity generation as needed.

In the trial, the team used water from the panel to irrigate a small patch of plants. Wang hopes large-scale systems could produce food, water and electricity all at once.

However, the design is still at an early stage. During the trial, the team manually opened and closed the condensation boxes. The hydrogel also deteriorated somewhat, so a more stable water-absorbing material is needed, Wang says.

A company called Sundrop Farms is already using solar power to allow it to grow tomatoes in a desert region in Australia. However, its greenhouse system relies on this power to desalinate seawater pumped from the nearby coast.

How to reduce waste while you renovate

How to reduce waste while you renovate

Construction and home renovations are notorious for the amount of waste they create. Think of how many times you’ve seen hulking construction dumpsters sitting in front of a house, brimming with wood scraps, drywall, old carpet, and all kinds of odds and ends that are almost guaranteed to end up in a landfill. They won’t be sorted or separated for recycling or compost — those dumpsters are nearly always upended in the nearest landfill Construction & Demolition area. Not only will this cost you a pretty penny, but that waste will negatively contribute to the ecology around the landfill, too.

So, what can you do? Lots! Depending on the type of renovation you’re looking at doing, there are many ways you can save money and be green. If you’re already used to reducing waste and being environmentally conscious, this is another excellent area to put your expertise to good use. If it’s something you want to get in the habit of, this is a great way to learn how to live more green overall.

If you’re planning for a larger renovation, do an online search for eco renovation companies in your area. This issue is coming to the forefront of homeowners’ minds, and as a result, contracting companies are adapting to their environmentally aware customers. They’ll be able to walk you through how they dispose of different materials from your reno, sustainable source products, or salvage from other job sites.

 

The 3 R’s – Relevant in Kindergarten, Relevant Now

Most of us will remember hearing the phrase, “Reduce, reuse, recycle!” bandied around schools, workplaces, or on TV at some point in our lives. This was always a good practice to follow and still is during your home reno project. Here’s how you can apply that old-school mantra now.

Reduce the amount of waste upfront. It’s staggering when you get an inside look into the amount of waste that many contractors consider to be just the price of doing business.

Why is this? There are a few main reasons. Most contractors learned their trades when construction materials were significantly less expensive than now and waste from off-cuts and scraps was less of an issue. In addition, the environmental movement has been gaining momentum over the past couple of decades, but it wasn’t always a consideration. Finally, the blunt truth is that it’s just easier for contractors to order more material and not optimize every piece that they’re using. This isn’t to say that they all do this, but it is a common practice, which is why it’s good to interview your contractor before you agree to work with them to get an idea of what their procedures are in this regard.

This requires a bit more time investment on your part, but it will pay off in savings and help you keep needless scraps out of the landfill. Asking questions about how many board feet your builder will need and comparing that to what they’re ordering can be an excellent way to track this. While it’s mostly impossible to make sure that every piece of every board or pipe is used, you’ll be able to monitor if the level of waste is reasonable. For example, if you’re putting in a 10-foot long, non-load bearing interior wall with studs 16 inches apart and a 9-foot ceiling, that’s about 120 total feet of 2×4 that you’ll need. If your builder suggests that they need to order 20 10-foot long 2x4s, you know that they’re over-ordering and not planning to optimize their use to reduce waste at the site. You can then ask them to do that, to find another area to use that 80 feet of off-cut, or order pre-cut material that fits your space and won’t generate any waste. These options will depend on your budget, builder, and your project and space specifics. This simplified example gives you a place to start thinking about questions to ask and how to approach this — we’re not contractors!

Re-use existing materials instead of purchasing brand new ones. You’d be shocked at how much building material gets ripped out during a renovation just to be heaved into a dumpster and then replaced with the same thing, only new.

For example, if you’re taking walls out, you’ll have 2×4 studs that will likely be somewhere around 8 feet. While you won’t want to reuse these as studs again necessarily, they’re perfectly good for use in other areas, like back framing.

Insulation can be reused as well — just know that as it ages, the R-value (the level to which it insulates) will decrease.

Even drywall can be reused if you’re keen enough or are working with a contractor that’s willing to spend some time on it. That goes for most of the ‘Reuse’ category – you have to have that conversation with your builder ahead of time because they won’t all be willing to do this. It takes more time to reuse old material than it does to send it to the dumpster and use neatly stacked, equal-sized 2x4s, and some builders just won’t want to take the extra time, even if you’re willing to pay for it.

Reusing items isn’t just for your building materials, either! Your interior decor can be upcycled or repurposed with a bit of gumption and some online tutorials, and who knows, you might love the DIY life and get into it regularly.

Recycle home renovation scraps instead of sending them to the landfill. This is another area that takes some dedicated time from you or agreement from your builder that they’ll handle this for you.

Recycling needs to be sorted, and this is the area that takes work in renovation projects. If you pull out a wall, for example, you’ll need to be sure to sort metal by separating the nails out of the studs and the electrical boxes and cable from the wood and drywall. The same goes for vinyl flooring, old carpet, and anything else that ends up coming out.

Once the sorting part is done, you’ll need to know where to dispose of everything properly. This will vary based on your location and the rules in your area, but you likely won’t have more than two or three stops to make to ensure you’re recycling instead of throwing out your construction waste.

 

What To Keep In Mind For Yourself, Or Communicate To Your Builder

Having stated goals is super important in keeping on track. That goes for you and for someone you hire! It also applies to your day-to-day efforts to live greener, not just in your eco renovation project.

Here’s our list to get you started:

  • Minimize the demolition work.
  • Use salvaged building materials.
  • Plan for deconstruction — meaning you can easily remove building parts during the next renovation.
  • Using materials that reduce waste during installation or use (that minimize packaging, adhesives, finishes, etc.).
  • Reduce and recycle waste during construction.
  • Use prefabricated components and materials prepared in a factory (such as framing) to reduce off-cut waste on your site.
  • Use standardized components that fit the dimensions of your house to reduce off-cut waste on your site.
  • Use materials and products that are durable, low maintenance, recyclable or reusable.

Products By Room To Keep Your Reno Eco-Friendly

If you plan ahead when you’re in the early stages, before you begin your eco renovation project, you’ll be able to think through what materials are coming out of each room and what you can use to build and redecorate to keep your materials environmentally responsible.

Painting – choose eco-friendly paints

Kitchen – reuse/repurpose kitchen cabinets, tips to save water, sell old appliances and fixtures

Bathroom – Pick water-wise fixtures, install energy-efficient equipment, eco-friendly materials

Living room – buy recycled furniture, upcycle your current furniture, save window hardware and screens, repurpose carpeting, etc.

Bedroom – salvage flooring, sell or donate doors

Remember that as you’re planning what you can do and what you need a contractor to do, there’s also a middle ground, and that’s your friendly neighborhood handyman. It’s a great option to call a handyperson to paint, assemble or disassemble furniture, or help with installations. These aren’t tasks a builder will do, but you can take some work off your plate using a handyperson!

 

Embrace a Zero Waste Lifestyle

This is your chance to make a significant impact on how much waste you produce — don’t let that stop with your eco renovation! Reducing daily waste is something that adds up quickly and makes a more significant impact than you might think, especially when that’s compounded over your lifestyle as a whole.

It takes some planning and coordination, but with a bit of extra thought and effort, your home renovation can be a great refresh for your life without having harmful impacts on the environment. You don’t have to be a DIY master to reduce, reuse, and recycle!

21 circular economy solutions: changing how we eat, live and travel for a more sustainable world

21 circular economy solutions: changing how we eat, live and travel for a more sustainable world
  • In 2019 the global economy consumed over 100 billion tonnes of materials.
  • The Circularity Gap Report highlights how moving to circular economy can reduce consumption levels and help mitigate climate change.
  • These 21 changes to how we make, keep and discard things can build more sustainable systems and a circular economy.

Never before has humankind made and consumed so much stuff. In 2019, for the first time, the global economy consumed over 100 billion tonnes of materials.

Already five of the nine planetary boundaries have been transgressed during humanity’s short presence on Earth, driven by a throwaway culture that too often exploits nature. Our economy has become inherently linear, and it may be difficult to reimagine how we make, use and discard things unless we shift toward a more regenerative and inherently natural system.

 

How can we build a circular economy?

The latest edition of the Circularity Gap Report explores the concept of a circular economy and investigates its role in climate mitigation and in cultivating more equitable societies around the world. Ultimately, the model will require a systems shift: radically rethinking how we use resources to fulfil our needs and wants. The report presents a range of circular solutions, based on four key principles of the circular economy: using fewer resources, using resources for longer, recycling resources and regenerating resources.

The report applies these strategies to “key societal needs and wants” – such as housing, nutrition and transport – to transform how resources are fed into the economy. If applied globally, this could result in a 28% reduction of resource use and greenhouse gas (GHG) emissions of 39% – keeping the world on track to reach its goal of limiting global warming to 1.5 degrees. Here we outline 21 strategies that can be applied in daily life, to businesses and at local and national government level. Importantly, these are not only grounded in energy policies – they go far beyond and span economic policy, industry, business and individual consumer behaviour.

 

Feeding the world and the circular economy

Providing nutrition to the world is an extremely resource and emissions intensive task: accounting for 10 billion tonnes of GHG emissions and 21.3 billion tonnes of resources a year. It’s also extremely inefficient as more than 30% of all food produced is thought to be wasted. While a massive proportion of the global population are malnourished, many others are overweight. Nutrition for all can be delivered with a fraction of the resources currently pumped into the linear food systems. The current model is ripe for change to a circular economy.

 

Build a circular economy through food sufficiency and cutting excess consumption.

 

1. Enough really can be enough

It’s extremely impactful to first slash excessive consumption before increasing production to tackle food shortages and scarcity. The words “no” and “refuse” are important in the circular economy.

2. Put healthier, satiating foods first

Let’s make cutting excess consumption tangible through food sufficiency: bringing the per capita caloric and protein intakes of high-income, high-emitter countries (such as the US or many in the EU, see the Shift profile on the right) down to match healthy levels – 2,000 calories a day for a typical woman. This can be done by reducing the material and emissions footprint per calorie of foods by prioritising healthier and more satiating foods over foods with low nutritional value. Think here of sugary beverages and refined, heavily processed items that require resources and energy to be produced, but their “empty calorie” effect on our stomachs means they are a wildly inefficient diet choice.

3. Embrace a plant-based diet

Animal-based proteins are yet another inefficient way to reach our daily calorie quota: 25kg of grain and about 15,000 litres of water is needed to produce only 1kg of beef – inputs that could instead be used to nourish humans. In some parts of the world, where a variety of other high protein, nutritious options are available, ditching animal proteins can be one of the most impactful individual actions for the climate. Eating a primarily plant-based diet could slash global emissions by 1.32 billion tonnes of carbon dioxide equivalents.

 

The role different countries play in reducing waste and building a systems approach for the circular economy.

 

4. Shop your fridge and cook creatively

Circular shifts will also deliver secondary benefits such as less packaging needed for food – a massive win in terms of reducing single-use plastic – reduced obesity and healthier overall communities. It could also help to reduce food waste, also a strategy in itself needed to make our food systems more circular. Try doing this at home by not only cutting excess consumption, but planning your meals ahead, looking up innovative recipes to make use of your broccoli stems or fruit peels, shopping your refrigerator before heading to the market and skipping impulse buys if possible. Food service can employ the use of AI apps, such as Winnow, which has been found to cut kitchen waste by 50% or more.

5. Check for certifications

Choosing food that is sustainably sourced – meaning it comes from ecosystems that are managed according to environmental standards that enable regeneration – is a strong circular choice. A range of sustainable and carbon-neutral certification schemes aim to provide this ethical stamp to consumers. Nowadays, even cheese can come with a PAS2060 certification, the international mark of carbon neutrality.

 

Eating a primarily plant-based diet could slash global emissions by 1.32 billion tonnes of carbon dioxide equivalents.

6. Support local

Sometimes we need to look to the past to learn lessons for the future. Practising the habits of our grandparents by going local and regional when picking our ingredients can have substantial environmental plus points. This often reduces the need for hot-housing vegetables, which equates to a reduction in fuel inputs, plus fewer food miles and lower transportation impacts. Supporting or practising urban, organic and precision farming models can also eliminate harmful synthetic fertiliser use, a huge source of emissions on its own.

In the UK, interest in allotments soared during the COVID-19 pandemic as home-grown food caught on. Lastly, backed by carbon-neutral biomass certification, using food waste and losses as animal feed – instead of the usual soy-based feeds – is an age-old tradition that will support the growth of secondary markets, take a chunk out of livestock emissions and help to avoid deforestation. While it’s not legal in the EU, it’s a successful practice in Japan and South Korea, where about 40% of food waste is used as feed.

7. Cook clean

Finally, cooking with polluting fuels is a silent killer: nearly 4 million people die a year from illness related to the associated pollution. Food preparation resources can also be made more circular, and safe, by replacing polluting traditional biomass and black carbon producing stoves with clean cooking apparatuses, including advanced solar-electric stoves. Increasing access to clean and sustainable energy around the world will be key to making this circular act available to those who most need it.

 

Homes and buildings and the circular economy

Providing shelter for the world is the most intensive “need” in terms of resources and emissions. Buildings are often developed without regard for the ecosystems of which they are a part. And in our civilisation’s history, we have built a lot: the mass of human-made things, from pavements to apartments to phones, now outweighs all natural biomass, such as trees and animals. Using circular economy strategies to lessen the load of our housing needs on the environment, and building with (rather than over) nature is imperative. Fulfilling the global economy’s need for housing is currently responsible for nearly 40 billion tonnes of resources and 13.5 billion tonnes of GHG emissions a year.

 

Multi-purpose buildings reduce the overall floor space needed and optimise resource efficiency, and also deliver proportional savings on heating and cooling.

8. Design flexible, multi-purpose homes

To make our need for housing circular, we must ultimately call for fewer, but better, new houses to be built and make using them for multiple purposes the norm, especially in higher-income countries where we have masses of stock already built up. To make the most of the buildings we already have, they should be used flexibly and be able to adapt as time and needs evolve. Imagine a hybrid building that is used as a flex-work office space, a community centre and an evening school. Such spaces can be payment-per-use, such as the cross-industry collaborative building Dutch Mountains in Eindhoven, the Netherlands. Multi-purpose buildings reduce the overall floor space needed and optimise resource efficiency, and also deliver proportional savings on heating and cooling. These savings will be further boosted by cuts in energy consumption that can be practised by anyone: lower room temperatures, smart metering and improved thermal insulation.

9. Use existing homes for longer

To continue making the most of the buildings already gracing the Earth, we must prioritise extending the lifetime of existing stock. Up until the 1960s there were strong traditions of reusing and sorting building materials, but this began to change as the construction industry in Europe moved from lime mortar to cement mortar, building materials became cheaper, and there were fewer requirements regarding the service life of buildings. Supporting and urging government interventions that ban building with virgin materials and policies to cap new construction in line with available volumes of secondary materials for building can reduce the need to extract finite materials from the Earth. Ultimately, waste from demolished buildings can be processed into new building materials, such as concrete mix or building sand. These options massively boost resource efficiency in production and performance.

10. No building left behind – or empty

Core circular methods must be practised at all levels, from the consumer to the national government. These include renovation, refurbishment, retrofitting and modular design. Modular design allows us to easily adapt buildings over time to suit changing needs and carries the potential for deconstruction, relocation and reuse of elements (or even whole buildings). Underused and disused buildings should also be occupied – in a time of resource scarcity buildings should not be sitting empty. Only with these methods can we try to meet the global housing demand within our global stock limits.

11. Nature-based solutions and renewable technologies

Nature-based solutions (NBS) can also lower material and energy demand for housing. We can be inspired by low-energy approaches such as Passivhaus design (this minimises the requirements for mechanical space heating, cooling and ventilation), while also applying renewable technologies such as solar photovoltaic or thermal, air-source and geothermal heat pumps to shrink the carbon footprint of a property. The Mahali Hub in South Africa are modular homes built with upcycled and locally available materials and a range of sustainable additions such as rainwater harvesting and passive cooling, resulting in net-zero homes.

We need to see the widespread use of low-carbon construction materials, material lightweighting and local sourcing to help to cut embodied energy in the housing system. And to add some regenerative power, the use of natural or renewable building materials, such as wood, straw and hemp, can boost biodiversity and regenerate ecosystems, while also generally slashing material footprints due to their lightweight character. Green roofs and living walls are all examples of NBS interventions with regenerative benefits, at least in terms of thermal performance, water management, biodiversity and air quality.

Consuming and producing goods and the circular economy

Fulfilling the societal need for consumables – a diverse group of items ranging from refrigerators and furniture to clothing and cleaning agents – is not hugely resource-intensive compared to housing, for example, at 6.9 billion tonnes of resources and 5.6 billion tonnes of GHG a year. However, it’s incredibly wasteful, toxic and it is a huge drain on a different set of resources: cotton, synthetic, fossil fuel-based materials such as polyester and all the dye pigments and chemicals that go with it.

The production of low-cost, synthetic materials, which form the backbone of cheap, fast fashion, has increased nine-fold in the past 50 years, using around 350 million barrels of oil each year and shedding microplastics in the process. Meanwhile, the fashion industry is responsible for a fifth of waste water globally. That’s why we must move towards a circular economy.

 

Shifting consumption choices and mainstreaming circular design, both usage and acquisition rates can decline.

—@circleeconomy

 

12. Make careful consumer choices

As we know by now, we need to begin by using less. Aside from conscious choices and utilising the all-important r-word – refuse – we need to start with the efficient design and use of consumer products. By shifting consumption choices and mainstreaming circular design, both usage and acquisition rates can decline. Tangible actions include: increasing digitisation to reduce paper use; not making textiles from animals; aiming to eradicate single-use plastic; optimising the usage of electronics to minimise e-waste; choosing only eco-labelled responsibly-sourced timber furniture, and prioritising local purchasing and sourcing.

13. Get repairing and sharing

We must also learn to make the most of the stuff we have. Here, encouraging repair, maintenance, sharing, re-manufacturing and take-back programmes for textiles, appliances, furniture and machinery are powerful and should form the base of circular systems. Durable denim meets circular business models in the case of Kuyichi: the company’s resale business model offers a take-back scheme for customers to easily give their denim a new lease of life to their denim, as well as a resale service for preloved goods.

14. Support ‘right to repair’

The backwards practice of designing products to break relatively quickly, planned or built-in obsolescence, must be eliminated, or we should choose not to invest in the companies that fail to do so. A phone with an old battery should not have to be tossed out and replaced, but should instead be repaired, the battery replaced easily with available and value-for-money replacement parts. Design for disassembly, customisation and replacement parts are all practical and marketable options that should become mainstream. The EU has no dedicated policy in place to stop the absurd practice of planned obsolescence, yet, Biden in the US has taken a bold and necessary step in formally backing “right to repair” legislation that calls on companies to release the knowledge and tools required to repair many common devices.

15. Consider chemicals

To reduce the level of toxins and pollutants in the environment, we should prioritise the use of sustainable materials for chemical-free consumables. This is imperative in light of recent research that posits that the fifth planetary boundary to be surpassed is chemical pollution – spurred by plastics and chemicals from farmland fertilisers, for example, leaching into the environment. We use products and dispose of them, but they don’t just go away. To avoid further environmental degradation, businesses and consumers alike can prioritise bio-based alternatives, chemicals leasing and natural fertilisers, and organic compost in gardens.

16. Recycle and help build secondary markets

We can also look to recycle our consumables when refusing, repairing or refurbishing are not possible avenues. Closing loops and boosting value in secondary markets will allow a circular market for consumables to thrive. To get there, governments must promote the recycling of plastics, synthetic fibres, paper, wood and wood by-products; as well as specifying recycled content obligations, and substituting them where possible for virgin or raw material. On the plastics front, a range of legislation in this arena has been rolled out: by 2030, all plastic bottles in the EU must contain 30% recycled content, while this stands at 50% in California; and in Maharashtra in India, industrial packaging produced in the state must include 20% recycled content. All steps in the right direction, but this has got to move faster, while concurrently turning off the plastics tap by reducing unnecessary plastics production. If applied globally, this could cut 1.23 billion tonnes of greenhouse gas emissions and save 2.18 billion tonnes of materials, according to the Circularity Gap Report 2022.

 

Mobility, travel and the circular economy

Mobility systems in their current form are responsible for 8.7 billion tonnes of resources and 17.1 billion tonnes of GHG emissions a year – coming in second only to housing. With its mammoth footprint and contribution to air pollution worldwide, mobility is commonly associated with GHG emissions reduction in the minds of both policymakers and the public.

Current mobility habits leave much to be desired. Privately owned vehicles in Europe sit unused for 90% of the time, while the phenomenon of “ghost flights” recently shocked the world: airlines flying empty planes just to retain flight slots, all the while spewing GHG emissions. From driving to flying, opportunities for change are plentiful as we look towards a circular economy.

 

We can learn a lot from the behaviours practiced during the COVID-19 lockdowns – namely a cut in long-distance travel and telecommuting for work.

—@circleeconomy

 

17. Travel less often

When it comes to cutting the resource and emissions intensity of mobility, the simplest way is to reduce travel. We can learn a lot from the behaviours practiced during the COVID-19 lockdowns – namely a cut in long-distance travel and telecommuting for work. Post-pandemic, these environmentally friendly behaviours can continue to be encouraged through a range of interventions.

The provision of regional and local hubs – the so-called 15-minute city being piloted in both Paris, the US and China, for example – allows residents to reach amenities within 15 minutes, either by foot, bike or public transport. Shared and virtual offices, telecommuting and working from home when possible can continue to be promoted by employers, especially as many companies acknowledge that staff productivity was maintained.

18. Go for lightweight designs

Vehicle design improvements are another more incremental way to reduce the level of materials used in mobility. Lightweight and smaller vehicles, such as cars and scooters, result in less steel and aluminium used for production, as well as lower fuel consumption and embodied energy.

19. Keep your car for longer

When it comes to prioritising durable design and material selection, plus optimising repairability and maximising maintenance, we can also use materials for longer – extending the lifetime of vehicles.

20. Share when you can

As well as better designed vehicles, better utilisation of all vehicles will further reduce the intensity of this societal need. With personal vehicle ownership no longer the dream it once was, interventions include shared mobility, via car clubs and pools, ride-sharing, and public transport, with park-and-ride provision to cut fuel consumption.

21. Design for reuse

Finally, optimising end-of-life vehicle management is critical to cycle flows, with the recycling of metal and plastic components, and the use of recycled materials, on the rise.

Electric truck hydropower, A flexible solution to hydropower in mountainous regions

Electric truck hydropower, A flexible solution to hydropower in mountainous regions

Electric Truck Hydropower & Mountain Regions

Mountain regions have a large potential for hydropower that cannot be harnessed effectively by conventional technologies. IIASA researcher Julian Hunt and an international team of researchers developed an innovative hydropower technology based on electric trucks that could provide a flexible and clean solution for electricity generation in mountainous regions.

In our transition towards a more sustainable future, hydropower will likely grow in importance as a renewable energy source. Despite its potential, innovation in hydropower technology has been slow in the last century. Conventional methods used today rely on two connected reservoirs with different water levels where the potential energy of the water is converted into electricity.

In steep mountain regions, the potential for generating electricity from a small stream of water is high, however, the hydropower potential of these regions remains untapped as it requires storage reservoirs, which have environmental and social impacts. IIASA researcher Julian Hunt and an international team of researchers developed a new technology called Electric Truck Hydropower that could become a key method for electricity generation in steep mountainous regions. The results of the study have been published in the journal Energy.

Electric Truck Hydropower would use the existing road infrastructure to transport water down the mountain in containers, applying the regenerative brakes of the electric truck to turn the potential energy of the water into electricity and charge the truck’s battery. The generated energy could then be sold to the grid or used by the truck itself to transport other goods. Electric Truck Hydropower could also generate electricity in combination with solar and wind resources or provide energy storage services to the grid.

“The ideal system configuration is in mountainous regions with steep roads, where the same electric trucks can be used to generate hydroelectric power from different locations. This increases the chances that water will be available,” says Hunt.

 

Figure: Schematic description of the system where the empty truck moves up the mountain to collect the containers filled with water at the charge site and the truck with the full container goes down the mountain generating electricity. The water is then unloaded at the discharge site.

 

The proposed technology is an innovative, clean source of electricity that is competitive with solar, wind, and conventional hydropower. Cost estimates show that the levelized cost of Electric Truck Hydropower is US$30–100 per MWh, which is considerably cheaper than conventional hydropower at US$50–200 per MWh.

The environmental impacts of Electric Truck Hydropower are also significantly smaller than that of conventional hydropower.

 

“This technology does not require dams, reservoirs, or tunnels, and it does not disrupt the natural flow of the river and fish passage. The system requires only roads, which already exist, charging and discharging stations similar to small car parks, a battery facility connected to the grid, and the trucks,” explains Hunt.

When looking at the global reach of this technology, the research team estimated that Electric Truck Hydropower could generate 1.2 PWh electricity per year, which is equivalent to about 4% of global energy consumption in 2019. The technology could harness the previously untapped potential for hydropower on steep mountain ranges. The regions with the highest potential are the Himalayas and the Andes.

“It is an interesting electricity generation alternative due to its high flexibility. For example, if a country is in an energy crisis, it can buy several electric trucks to generate hydropower. Once the crisis is over, the trucks can be used to transport cargo,” Hunt concludes.

Waitrose and Muller to scrap coloured caps on milk bottles in recycling trial

Waitrose and Muller to scrap coloured caps on milk bottles in recycling trial

Waitrose has partnered with Muller to scrap coloured caps on milk bottles as part of a plastic recycling trial.

The supermarket chain will sell Muller products with clear caps on their bottles, which can be recycled into food-grade packaging, unlike the usual blue, green and red lids.

The businesses estimate that this could increase the availability of recyclable plastic, high-density polyethylene (rHDPE) on the market by 1,560 tonnes a year.

The trial will take place at all 331 Waitrose stores between April 4 and 30, following a successful in-house trial, they added.

Research conducted by Muller found that the majority of shoppers support the change, with 80% telling the brand they would choose a bottle with a recyclable clear cap over a coloured cap.

Liam McNamara, commercial director at Muller Milk & Ingredients, said: “Everyone is thinking more about what they buy, the nutritional benefits, the value it represents and the packaging used.

“We want to be the partner of choice for our customers, we recognise the commitments they are making in this area, and following a successful trial period, then this is another step we can offer.

“As the first dairy company in the UK to trial clear caps on fresh milk, we are working hard to innovate and lead in issues that are not only important for customers, but for consumers too.”

Karen Graley, packaging innovation lead at Waitrose, said: “As food businesses, we need to do more to protect our planet from unnecessary plastic waste so we’re delighted to be involved in this trial.”

 


ECD Automotive goes the extra mile building fully-custom electric Land Rover Defenders

ECD Automotive goes the extra mile building fully-custom electric Land Rover Defenders

The world of aftermarket tuning has never failed to amaze us. Tuners have been building cars that range from being capable of running 7-seconds in street-trim, to perfect classic restorations as reliable as your new Camry. While we all love the rumble, fire-spitting, E85 smell of tuned internal combustion engines, we can’t deny that the last decade has seen an impressive rise in electric engines, both from the OEM and aftermarket sides.

An Innovator like Bisi Ezerioha of Bisimoto made his name off of building and racing Hondas. Now he’s putting all his expertise into mind-blowing electric vehicles. The revolution is diverse, however, and while Bisi comes from a car-tuning background, companies such as E.C.D. Automotive Design is approaching their business from an enthusiast perspective.

E.C.D went from having a passion for classic Land Rovers, to building a Tesla-powered Defender with no bolt left unturned. Best of all, customers can now build their very own, fully-custom Land Rover Defender through E.C.D. Automotive Design. We talked to E.C.D.’s Co-Founder, Elliot Humble, to find out how this works and the level of quality and parts on these vehicles.

 

How E.C.D. Automotive Design Started

 

 

Elliot and Tom Humble, brothers from England 40-miles away from the Lode Lane Factory that produced the Land Rover Defender, founded E.C.D Automotive Design. The brothers met Scott Wallace, another automotive enthusiast that would soon become the third partner in the company.

“We founded E.C.D. as car-enthusiasts first,” said Elliot Humble, E.C.D. Automotive Design Co-Founder. “My brother, Tom, and a friend named Scott Wallace were both in Florida for other reasons, and one night over a pack of beer they daydreamed up E.C.D. The next day, Tom quit his job and started building out E.C.D.’s business plan. I left school to join them on this venture.”

In 2013, the three musketeers opened their very first workshop/showroom, working 18-hour days, tearing down Land Rovers, and rebuilding them to their few clients’ wishes. At some point, E.C.D. realized that outsourcing some of the work locally wasn’t ideal, and they had to make a decision. After a small talk, they determined that E.C.D. will have to go all out with a mission to build the highest-quality custom-builds – all in-house.

“The main thing was finding and working with the correct partners to evolve the electric integration to our classic cars. We found that in Electric Classic Cars (ECC).”

The decision led to a complete expansion, with a 30,000 square-foot facility. The facility allows them to do everything in-house, from paint and bodywork, to the final touches and delivery of the projects. This finally gave E.C.D. Automotive Design what they were looking for: complete control. In 2017, the company announced their newest addition, the new Malibu Design Studio in California. This expansion inspired Elliot to look back in remembrance of how it all started.

 

 

“Before E.C.D., I was a student over in England. I didn’t have any previous experience working on trucks like we do now, but I knew I loved them,” said Elliot. “Nowadays, I’m our operations manager, where I do everything from increasing our productivity on-site at the Rover Dome to figuring out how we’re going to make our clients’ wildest dreams come to life.” With the clients’ wildest dreams reaching very high, the evolution of these builds went from custom restorations with LS1 engines, to going full electric with Project Britton.

 

The Land Rover Defender’s Enthusiast Attraction

 

 

Before Land Rover turned into a luxury icon that every celebrity has to have, it was known to be an agriculture four-wheel drive SUV. Land Rover first came on the scene in 1948. With inspiration from the Jeep Willys, the Series I came with a steel frame under an aluminum body. The Land Rover continued building its reputation, but it wasn’t until 1990 that the name “Defender” was born. The Defender stayed on the scene until 2016 when it ceased production, making it a legendary milestone in Land Rover’s history.

Today, enthusiasts from around the world seek this platform for complete restorations. With E.C.D. being the largest and leading authority in custom restorations of these Defenders and classic Land Rovers, they had to push the envelope. Enter Project Britton, the Tesla-powered electric Defender 110. Better yet, customers can now customize and build their very own electric Defenders.

“No, we did not have any formal connection with Land Rovers. My brother, Tom Humble and I grew up near the Jaguar Land Rover plant and have always loved Land Rovers, though,” said Elliot.

 

E.C.D.’s Tesla-Powered Land Rover Defender

 

 

E.C.D. had to restore Project Britton from the ground up. Everything from upholstery to miles of wiring had to be gone through in order to produce this electric Defender. The Tesla-motor allows the Defender to deliver 450 horsepower, which bolts the vintage SUV to 60 mph from a stop in just five seconds courtesy of the 100-kWh battery pack. In addition to the impressive torque, the Tesla-powered Land Rover Defender has over 220 miles of range on tap, with five hours of charge needed to get there.

“At the end of the day, we’re doing this with deep love of older Defenders and a passion to keep them on the road by modifying them to fit into our client’s lives,” E.C.D. Co-Founder Elliot Humble said. “Whether it takes figuring out how to engineer an electric engine into a restored Defender or color-matching the paint to match a favorite shirt, our world-class team can breathe life to our clients’ wildest dreams.”

 

Project Britton Build Specs

 

 

E.C.D. Automotive Design were able to take a 107-horsepower gas guzzler, and turn it into a masterpiece that delivers well over four-times its original power, all with an electric motor. With the tremendous increase in power, the original parts are no longer able to withstand the abuse.

The first parts to go when you send instant torque to the wheels are the axles. The company’s standard procedure is to test each project for 750-miles. This allowed them to find the right upgrades for the axles. The whole car features E.C.D.’s Air Ride suspension, and equipped with high-performance Brembo brakes.

To maintain its off-roading capabilities, a set of BF Goodrich Rugged Trail T/A tires sit on all four-corners, wrapped around 18-inch Hawke Osprey Design silver wheels. This not only gives the Defender an aggressive look, it also gives it the capabilities to go with it.

 

The Defender’s Interior And Exterior Upgrades

 

 

Enhancing the looks of the Defender is no easy feat. After all, its iconic looks stood the test of time. This meant that the taste in design was critical. E.C.D. painted the exterior in Cool Khaki Grey with an Alpine White roof, along with some silver accents to go with the wheels. The team also paid special attention to bold accents around the shell, like the heritage-style grille, swing-away wheel carrier, sidesteps with the SVX silver inserts, and the front-runner roof rack and ladder.

On the inside, the Recaro Expert S seats wrapped in sand beige Porsche Nappa leather provide comfort and support to the driver and passenger. Aside from their great looks, the Recaro seats are both heated and ventilated. While the gauges are all electric, the steering wheel bridges the gap back to classic with its Evander Wood finish. The wood finish continues, this time in a teak wood finish, on the flooring of the rear cargo, with a matching teak wood storage bench that not only gives it an incredible look, but also offers plenty of storage.

 

 

Technology is far ahead of its original age, with an Alpine Floating Halo infotainment system. The system comes with Bluetooth capabilities and WiFi, as well as three charging pads for your phone. Project Britton also features remote start, blind spot monitor, backup sensors, as well as front and rear cameras. Since E.C.D. isn’t new to electric conversions, they were able to go through all the hoops to make this build 50-state legal – a complete game-changer that justifies its high-cost.

 

The Process Each Land Rover Build Goes Through

 

 

With projects like this giving customers complete freedom over their build, the team at E.C.D. has to ensure quality is top-notch throughout the challenges that arise. “Each build is a one-of-one vehicle,” said Elliot. “Each client goes through our detailed design process and is able to choose everything, from the type of stitching to the exterior trim color. When they bring the car onto the line, it follows our streamlined process. The build goes through 20 stations, spending 5 days at each station.”

In spite of the 20 stations taking 100 days to build, the company has been producing 60 cars per year and in the process of scaling up to 100 cars per year. “From start to finish, the build receives 2,200 hours of labor, and it takes customers 14 months to receive their vehicle,” said Elliot.

 

E.C.D. Electric Defender Cost

 

 

The question is, how much would it cost you to build an electric Defender with E.C.D.? Since each build is completely different from the one before, it’s nearly impossible to put a precise price-tag on your dream build. However, the company estimates that your very own Land Rover Defender will be in the range of $200,000 to $300,000.

The number seems extremely high, but when you look at the specs of the vehicle, the amount of engineering that goes into it, the level of customization you have, and the quality of the end-product; it all makes sense. Given that many new SUVs are knocking on the mid-$100,000 door, it’s clearly much cooler to pay the extra money and daily-drive a vintage Defender.

“We restore Land Rovers because we love them. Our passion for these British cars is what got us here in the first place. As long as people love the trucks as much as we do, we’ll continue restoring them. Soon, we plan to branch out from old Land Rover Defenders and Range Rovers to take on electric conversions for classic Jaguars,” Elliot passionately explains.

Just when you think E.C.D. has reached a level where they aren’t looking for improvement, Elliot tells us: “There is always room for improvements and our three quality control departments add those amends as the truck moves through our industry leading digital QC process.” We are excited to start seeing these vintage Land Rovers on the streets and seeing the evolution of the company and how far Tom, Elliot, and Scott can take it.

“Our success comes from being outsiders in the industry. We live by our motto, ‘To evolve not to exist,’ and we are constantly looking for ways to improve the business. Since none of us had worked in the automotive industry in this capacity, we’re able to see things from a different perspective and offer innovative services to our clients,” he concluded. Elliot promised that this year will see some more exciting projects that support their motto and philosophy, and HotCars will be right there to cover it.

Future cities could be 3D printed – using concrete made with recycled glass

Future cities could be 3D printed – using concrete made with recycled glass

3D printed concrete may lead to a shift in architecture and construction. Because it can be used to produce new shapes and forms that current technologies struggle with, it may change the centuries-old processes and procedures that are still used to construct buildings, resulting in lower costs and saved time.

However, concrete has a significant environmental impact. Vast quantities of natural sand are currently used to meet the world’s insatiable appetite for concrete, at great cost to the environment. In general, the construction industry struggles with sustainability. It creates around 35% of all landfill waste globally.

Our new research suggests a way to curb this impact. We have trialled using recycled glass as a component of concrete for 3D printing.

Concrete is made of a mix of cement, water, and aggregates such as sand. We trialled replacing up to 100% of the aggregate in the mix with glass. Simply put, glass is produced from sand, is easy to recycle, and can be used to make concrete without any complex processing.

Demand from the construction industry could also help ensure glass is recycled. In 2018 in the US only a quarter of glass was recycled, with more than half going to landfill.

 

Building better

We used brown soda-lime beverage glass obtained from a local recycling company. The glass bottles were first crushed using a crushing machine and then the crushed pieces were washed, dried, milled, and sieved. The resulting particles were smaller than a millimetre square.

The crushed glass was then used to make concrete in the same way that sand would be. We used this concrete to 3D print wall elements and prefabricated building blocks that could be fitted together to make a whole building.

If used in this way, waste glass can find a new life as part of a construction material.

The presence of glass does not only solve the problem of waste but also contributes to the development of a concrete with superior properties than that containing natural sand.

The thermal conductivity of soda-lime glass – the most common type of glass, which you find in windows and bottles – is more than three times lower than that of quartz aggregate, which is used extensively in concrete. This means that concrete containing recycled glass has better insulation properties. They could substantially decrease the costs required for cooling or heating during summer or winter.

 

Improving sustainability

We also made other changes to the concrete mixture in order to make it more sustainable as a building material, including replacing some of the Portland cement with limestone powder.

Portland cement is a key component of concrete, used to bind the other ingredients together into a mix that will harden. However, the production of ordinary Portland cement leads to the release of significant amounts of carbon dioxide as well as other greenhouse gases. The cement production industry accounts for around 8% of all carbon dioxide emissions in the environment.

Limestone is less hazardous and has less environmental impact during the its production process than Portland cement. It can be used instead of ordinary Portland cement in concrete for 3D printing without a reduction in the quality of the printing mixture.

We also added lightweight fillers, made from tiny hollow thermoplastic spheres, to reduce the density of the concrete. This changed the thermal conductivity of the concrete, reducing it by up to 40% when compared with other concrete used for 3D printing. This further improved the insulation properties of the concrete, and reduced the amount of raw material required.

Using 3D printing technology, we can simply develop a wall structure on a computer, convert it to simple code and send it to a 3D printer to be constructed. 3D printers can operate for 24 hours a day, decrease the amount of waste produced, as well as increase the safety of construction workers.

Our research shows that an ultra-lightweight, well insulated 3D building is possible – something that could be a vital step on our mission towards net zero.
