How Singapore is turning multi-storey car parks into farms

How Singapore is turning multi-storey car parks into farms

Eyleen Goh runs a farm from the top deck of a car park in Singapore.

And this is not a small operation – it supplies nearby retailers with up to 400kg of vegetables a day, she says.

“Singapore is quite small but we have many car parks. It is pretty much the dream to have farms [here] to meet the needs of residents in the community,” she says.

At least a dozen of these rooftop farms have now sprouted up across the South East Asian city state.

The government started leasing out the unusual plots in 2020 as part of its plans to increase local food production. The country of 5.5m people currently imports more than 90% of its food.

But space in this densely populated island nation is scarce and that means land is not cheap. Singapore has some of the world’s most expensive property.

One farmer told the BBC that the high cost of his first car park plot meant that he had to give it up and move to a cheaper location.

When BBC News visited Ms Goh’s farm, which is about the third of the size of a football field, operations were in full swing.

Workers were picking, trimming and packing choy sum, a leafy green vegetable used in Chinese cooking.

At the other end of the facility meanwhile, another employee was busy re-potting seedlings.

“We are harvesting every day. Depending on the vegetables we are growing, it can range from 100kg to 200kg to 400kg per day,” Ms Goh says.

She says starting the farm cost around S$1m ($719,920; £597,720), with much of the money being spent on equipment to help speed up harvesting.

Although she has received some subsidies, Ms Goh says her business is not profitable yet.

She has 10 employees and pays a rent of around S$90,000 a year for the space and another car park site, which is still being set up.

“Our setting up period happened during the Covid pandemic, so logistics were way more expensive and took a longer time,” Ms Goh explains.

“Moreover, this was the first rooftop car park tender awarded [by the government] so the process was very new to everyone,” she adds.

Singapore’s rooftop farmers are also finding other ways to make money.

Nicholas Goh, who is not related to Ms Goh, says he has managed to turn a profit by charging people a monthly fee to harvest vegetables at his urban farm.

He says the idea is particularly popular with families who live nearby as “it is a community kind of approach, rather than a commercial approach”.

However, another urban farmer, Mark Lee, says high costs have driven him to move to an industrial building that charges a “negligible” i.e. lower rent.

“Vegetables are ultimately just vegetables. You can get it at the freshest and best quality but there is limitation to how much one would pay. We’re not talking about truffles here,” Mr Lee says.

 

‘Existential issue’

Rooftop farms are not the only way Singapore aims to increase the amount of food it grows.

Most of the country’s home-grown produce comes from high-tech facilities that are heavily subsidised by the government. It had 238 licensed farms in 2020, according to official figures.

Some of the farms are already profitable, and can expand their production to increase profits, the Singapore Food Agency (SFA) says.

“Food security is an existential issue for Singapore. As a globally connected small city-state with limited resources, Singapore is vulnerable to external shocks and supply disruptions,” an SFA spokesperson tells BBC News.

“This is why it is important that we continuously take steps to secure our essential resources,” the spokesperson adds.

 

The farms are located in public housing estates. NATURE’S INTERNATIONAL COMMODITY

 

Earlier this year, the issue of food security came into sharp focus in Singapore when several countries in the region banned or limited exports of key foods.

Governments reliant on imports tried to protect their food supplies as the Ukraine war and the pandemic pushed up the cost of everything from staple foods to crude oil.

By 2030, Singapore aims to produce 30% of the food it consumes itself – more than three times the current amount.

Professor William Chen of Singapore’s Nanyang Technological University says more support should be offered to urban farms.

“There are measures in place such as productivity grants from SFA, and regular farmers’ markets to encourage consumers to buy more local produce,” says Prof Chen, who is a director of the university’s food science and technology programme.

“Perhaps helping local farmers to adopt simple technologies… may be considered,” he says.

However, Sonia Akter, an assistant professor at the Lee Kuan Yew School of Public Policy, believes high operating costs are likely to remain a major challenge for urban farmers.

“Singapore is offering a lot of subsidies and financial support to entrepreneurs who are working in this space,” she says.

“The question is whether these farms will be able to operate and be commercially viable when the government support stops flowing.”

Back on a rooftop surrounded by tower blocks in the midst of Singapore’s urban sprawl, Ms Goh may seem a world away from traditional agriculture.

However, she echoes the sentiments of generations of farmers who have come before her: “Giving up is not an option. The more challenging it is, the more rewarding it will be.”

What does true sustainability look like in the hotel industry?

What does true sustainability look like in the hotel industry?

In a bid to become more environmentally sustainable, Raffles Hotel Singapore has reimagined its signature drink: the Singapore Sling, a fruity gin-based cocktail dating back to the 1900s.

In 2018, the 5-star ultra luxury hotel partnered with spirits company Proof & Company’s ecoSPIRITS programme to transform the drink’s life cycle. Using a closed-loop distribution system, they were able to eliminate several thousand kilograms of packaging waste annually. Furthermore, for every 25 Singapore Slings served, a native tree is planted in Kalimantan and Sumatran rainforests.

According to consultancy firm Deloitte’s calculations, every glass of Singapore Sling now emits 200 fewer grams of carbon dioxide than before.

Raffles Hotel is not the only establishment raising its sustainability game. In 2019, Marriott International, the world’s largest hotel chain, phased out single-use plastic toiletry bottles in favour of larger pump dispenser bottles. Meanwhile, Hilton committed to reducing food waste by 50 per cent by 2030.

Many of these initiatives are driven by consumer demand for more sustainable accommodation, which has skyrocketed in recent years. According to Booking.com’s 2021 Sustainable Travel Report, 81 per cent of travellers said that they want to stay in sustainable accommodation in the upcoming year, a significant jump from 62 per cent in 2016.

Local hospitality and tourism institutions are also putting greater pressure on hotels to decarbonise. In March 2022, the Singapore Hotel Association (SHA) and Singapore Tourism Board (STB) launched a Hotel Sustainability Roadmap which urged establishments to reduce emissions by 2030 and reach net-zero emissions by 2050.

“There’s just more pressure all around now,” said Eric Ricaurte, founder of hospitality consulting firm Greenview. “While previously we only saw incremental changes like reusing linen towels, hotels are now also paying attention to issues like energy and carbon. We’re seeing sustainability appear on the radars of hotels everywhere.”

But amidst hotels’ greater focus on sustainability, how many of these changes are greenwashing — initiatives designed to mislead guests and present a false environmentally responsible public image?

 

There is some great work happening, but there’s a lot of PR-driven hot air too.

– Tim Williamson, customer director, Responsible Travel

 

Greenwashing, or genuine change?

There’s a mix of both, says Tim Williamson, customer director of Responsible Travel, an activist company seeking to design conscious trips.

“There is some great work happening, but there’s a lot of PR-driven hot air too,” said Williamson. “For example, while some hotels have set net zero targets, they may ‘hide behind’ carbon offsetting to reach these goals, which is not the same as a real reduction in their emissions.”

According to Ricaurte, another form of greenwashing is when hotels offer an asymmetrical representation of their environmental impact. He pointed to some hotels which may have removed plastic straws, but still use large amounts of plastic in other aspects of their operations.

To identify hotels that genuinely care about sustainability, Ricaurte said guests could consider whether the hotel pays attention to both lower-hanging fruit — like providing plant-based options on their restaurant menus — as well as formal certifications.

There is currently a growing list of globally-recognised sustainability certifications for the hotel sector, including the Green Key eco-label, Green Globe, as well as Booking.com’s recently launched Travel Sustainable Badge. But Williamson says not all certifications are created equally. Less credible schemes may only require hotels to undertake a self-assessment, rather than be evaluated by an independent third party.

“There is also the issue of what is relevant,” said Williamson. “Reducing water consumption may be less of a priority for a hotel in Scotland than for a hotel in a drought-ridden area of southern Spain, but many green certification schemes don’t make this distinction. This means businesses may have a green badge but still be failing to address the challenges most pressing in their local area.”

Rather than relying solely on certifications, Williamson instead encouraged consumers to “look behind the labels” and ask for written policies and specific examples.

“What percentage of employees are local, and do they receive a fair wage? How much of the produce is sourced from local suppliers? What are they doing to help protect and restore nature, and how are they cutting food waste? Don’t take all labels at face value,” he said.

 

Transparency trade-offs

While green marketing is on the rise, not all hotels have opted to integrate sustainability into their branding. Raffles Hotel Singapore, for example, features little about sustainability on its website.

“We think that sustainability and saving the planet shouldn’t be used as marketing highlights,” explained general manager Christian Westbeld. “They should be something that you really live by. We all have to do the right thing.”

Westbeld says that when the hotel closed its doors for extensive restoration from December 2017 to August 2019, sustainability was high on the agenda. The environmental footprint was taken into consideration in all aspects, from the plumbing systems to kitchen equipment, and even the linen in each guest suite.

“For example, the windows in each suite are now double glazed to better retain cold temperatures, therefore encouraging guests to use air-conditioning for shorter periods of time,” said Westbeld.

However, most of this information is not highlighted to travellers on Raffles Hotel’s marketing platforms.

Dr Victor Nian, Chief Executive Officer of Singapore-based think tank Centre for Strategic Energy and Resources, said such an approach eliminates the issue of greenwashing entirely. However, he cautioned that transparency is also very important.

“If a hotel publishes a sustainability report on their website, it’s often a positive sign that they are trying to do something. It also gives you a chance to compare sustainability among different hotels,” he said, adding that such reports are often endorsed by a verified body.

“But if they don’t publish anything, people won’t know what they are doing at all,” he said.

Laura Houldsworth, Asia Pacific managing director at Booking.com, an online travel agency, shared similar views: “We think hotels should be encouraged to share their sustainability initiatives. We believe in educating travellers and empowering them with the right knowledge, so they know how to avoid these pitfalls.”

 

An uphill battle

Westbeld admits it can be difficult to prioritise sustainability as an ultra luxury destination.

“We will never compromise on service standards and guest experience,” he said. “For example, we won’t openly recommend guests not to change sheets. It is a guest’s choice — they can approach us and say they only want to change it every other day. But we don’t compromise on hygiene and comfort.”

Hotels also face constraints that they may not be able to immediately address.

According to Ricaurte, one of the biggest challenges in reducing emissions is the design of the building itself, since the key moments when those design decisions are made may not have factored in sustainability. This results in the hotel lagging behind on building sustainability standards.

Hotels are often also constrained by their location and local energy grid.

“In Singapore, if the electricity grid is mostly powered by fossil fuels, there’s very little hotels can do to decarbonise that,” said Dr Nian.

While there are still ways hotels can reduce their energy consumption, such as improving the air-conditioning efficiency or exploring rooftop solar, Dr Nian said that these measures often have limited impact in driving down absolute emissions. Hotels may also be reluctant to implement these changes due to cost barriers, he added.

Ultimately, as demand for sustainability grows, the notion of luxury may need to be redefined for travellers and hoteliers alike to meet their sustainability goals, says Responsible Travel’s Williamson.

“Luxury doesn’t have to be all about air-con and all-inclusives. It can also be about bespoke, authentic experiences and great personal service,” he said. “It could be a small, locally-owned hotel with its own vegetable garden and hosts who know the best off-the-beaten-track spots for hiking, food and culture. Or a small ship cruise which really gets you into the nooks and crannies of a place, instead of a colossal liner.”

“High-value, low-impact tourism can benefit local communities and important conservation work too. Everyone wins.”

Scientists from A*Star, NTU find way to upcycle old solar panels

Scientists from A*Star, NTU find way to upcycle old solar panels

Recycling old solar panels is challenging, but scientists from Singapore have found a way to upcycle the silicon inside and turn them into materials that can convert heat into electricity.

The team comprising researchers from the Agency for Science, Technology and Research (A*Star) and Nanyang Technological University (NTU) turned old solar panels into thermoelectric materials.

Such materials convert heat into electricity, and work in a similar way to how hydropower generation plants use water movement to drive turbines to generate electricity.

The joint study was published in the scientific journal Advanced Materials in March.

Dr Ady Suwardi, the deputy head of the soft materials research department at A*Star’s Institute of Materials Research and Engineering said that by moving heat from one side to another, thermoelectric materials generate electricity.

This can then be used for applications like cooling, added Dr Ady, who co-led the study.

The team found that impurities and defects in the silicon used to make solar cells actually enhance the performance of thermoelectric materials.

A solar panel is made up of many solar cells, also known as photovoltaic cells.

Separating the materials used to make solar panels and recycling each of them is a complex and costly process, said Associate Professor Nripan Mathews.

Prof Mathews, who is the cluster director of renewables and low-carbon generation (solar) at the Energy Research Institute @NTU (ERI@N), added that current recycling methods are able to recover only the glass and metallic support structures from solar panels.

Solar cells contain a complex mix of materials such as aluminium, copper, silver, lead, plastic and silicon.

Silicon, which is extremely pure, makes up 90 per cent of solar cells. However, this normally ends up in landfills.

This is because silicon has to be chemically treated and remelted to be recycled into pure silicon, said Prof Mathews.

He added that it is challenging, energy-intensive and expensive to recover the silicon to create new, functional solar cells.

“While silicon holds very little weight in the entire solar panel, it is the most valuable part of it, which explains why it is important for us to try and upcycle it,” said Prof Mathews.

The team is currently looking to pilot the technology for large-scale upcycling of waste silicon to create silicon-based thermoelectrics.

This can be used for high-temperature energy harvesting applications such as converting heat generated from industrial waste processes into electricity.

There are a number of research efforts ongoing in Singapore to see how solar panels can be recycled.

The NTU project, for example, is one of two currently supported by the National Environment Agency’s (NEA) Closing the Waste Loop funding initiative.

The $45 million initiative was launched in 2017 to boost research and development in areas such as the recovery of materials from waste streams.

The other project, a recycling programme led by Singapore Polytechnic (SP), aims to recycle solar panels on a commercial scale and recover more than 90 per cent by weight of the materials from the solar panels, said NEA.

In 2019, The Straits Times reported that Sembcorp and SP will also work together to develop a pilot recycling plant for solar panels.

However, the institutions declined to comment when asked for updates on the effort.

Another research effort by NTU spin-off EtaVolt, a solar tech firm, is working with the university on various other solar recycling projects, said its co-founder and chief executive Stanley Wang.

The project is not funded by NEA’s Closing the Waste Loop initiative.

Dr Wang said that the upcoming projects aim to recover materials from decommissioned solar panels so they can be recycled and reutilised as raw materials for battery, solar panel manufacturing and other industrial applications.

“This would allow us to recover the end-of-life value of these raw materials, which can potentially be given back to companies in the form of rebates to incentivise them to recycle their solar panels sustainably,” he added.

Sustainable shopping: How this mall wants to help save the planet with you

Sustainable shopping: How this mall wants to help save the planet with you

In recent years, terms like “fast fashion” and “overconsumption” have seeped into modern society’s consciousness, giving shopping a bad rap. Raffles City is changing that, one eco step at a time.

Through the Project Green campaign–a series of sustainability initiatives involving retail, hospitality and corporate stakeholders–Raffles City Singapore is revolutionising its retail experience for the better.

“By providing our retailers, office tenants and hotels a suitable platform via Project Green to expand on their green offerings, Raffles City aspires to make a bigger impact to inculcate sustainable living in the daily lives of our shoppers and stakeholders, and to adopt an eco-conscious attitude to make a positive impact on our planet together,” says general manager of Raffles City Singapore, Steve Ng.

 

Raffles City’s Project Green showcase is held at Level 3 Atrium and features activities you can take part in. PHOTO: RAFFLES CITY

 

From July 8 to Sept 25, there will be a slew of activities lined up for shoppers at the mall. Discover your inner eco-warrior when you take part in workshops that teach you how to incorporate recycling into your everyday life, through ordinary activities like dining and shopping. Here are three easy ways to get involved.

 

Learning to go green

Held at Raffles City Level 3 Atrium, the Project Green showcase features brands within the mall and their sustainability efforts.

Leading by example, Raffles City has created part of the display using upcycled materials from the mall’s past Christmas decorations. It includes a prominent tree centrepiece with two bicycles that shoppers can pedal to power up the lights.

At the F&B and beauty zones are Nespresso and L’Occitane, which will hold masterclasses and upcycling workshops. Learn how Nespresso recycles their used capsules, turning them into new aluminium objects, while L’Occitane unveils its Recycling Program – the first in Singapore to accept empty packing from any beauty brand. And while you’re at it, why not pop by their first and only eco store in Singapore on Level 1?

Social enterprise Terra SG, known for its engaging eco-education programmes, will be running weekend public workshops. Featured mall tenants will also take turns to run workshops that help educate shoppers on other ways to go green.

 

Recycling as a lifelong journey

Going green is not just in fashion these days – it’s essential to help reduce our carbon footprint and preserve the Earth for the generations to come.

Unsure how to start? Head to the Green Corner at Lobby A on Basement 2 for inspiration.

A permanent set-up, the space has been reimagined and decked out with preserved moss, recycled wood and steel frames, with low-energy lighting and interactive elements.

 

Located at Basement 2, Lobby A, the Green Corner is a great place to learn about adopting recycling habits. PHOTO: RAFFLES CITY

 

To be refreshed every quarter, the Green Corner is designed to educate the public about sustainability and how to adopt good recycling habits.

Featuring interactive educational displays, vending machines which take in recyclable items, as well as recycling and e-waste bins, the Green Corner also has a Bag Sharing Station for shoppers to, well, share the love by depositing their unused paper bags for other shoppers to take and use.

 

Making a difference with your shopping

With beautifully designed reusable bags becoming commonplace in Singapore, make ‘Bagless Fridays’ your new shopping habit as you wind down for the weekend.

A new initiative by Raffles City, ‘Bagless Fridays’ will take place throughout the Project Green campaign. Shoppers are encouraged to BYOR (Bring Your Own Reusables), with participating tenants not offering shopping bags in order to reduce plastic bag use and wastage.

As a bonus, shoppers who use their own recyclable bags at participating stores at Raffles City can earn double STAR$ on the CapitaStar app.

For a minimum spend of $450, shoppers will receive a Raffles City x Tiong Bahru Bakery limited edition reusable Sttoke cup specially designed in celebration of the bakery’s 10th anniversary.

Singapore green-lights nuclear power in low-carbon energy import proposals

Singapore green-lights nuclear power in low-carbon energy import proposals

Singapore’s Energy Market Authority (EMA) is allowing firms to propose importing nuclear energy as part of a scheme to acquire low-carbon electricity from overseas.

Only plans involving coal will be rejected outright in the latest call for applications that started on Friday (1 July). In an earlier round that ended in April, both coal and nuclear power were banned.

EMA said it is open to proposals from “diverse” low-carbon energy sources in the region, in response to a query from Eco-Business on why the change was made.

“EMA will also be considering a range of factors such as price-competitiveness, source diversity and safety when evaluating the proposals,” added Lee Seng Wai, director of the energy connections office at EMA.

Singapore wants to fulfil four gigawatts, or 30 per cent of its energy supply, by 2035 with imports of clean energy – defined as electricity produced with at most 150 kilograms of carbon dioxide emissions per megawatt-hour. Projects could start higher but must reach this level within five years of commercial operation.

Nuclear energy could fit the bill, with an “emissions factor” of 13 kilograms of CO₂ per megawatt-hour, on par with wind power and about a third of solar power, according to the United States energy department.

 

Emissions factors of various sources of energy, along with Singapore’s aggregate electricity generation, which is largely via natural gas. Data: US National Renewable Energy Laboratory, Singapore Energy Market Authority.

 

Singapore currently produces electricity almost entirely with natural gas. Each megawatt-hour generated creates about 400 kilograms of carbon emissions, according to EMA.

Proponents of nuclear power say the energy source can provide a consistent flow of low-carbon electricity – something wind and sunlight struggle to achieve. Critics fear the lasting impact of both disasters and nuclear waste, a permanent solution for which largely does not exist.

Neighbouring Malaysia and Indonesia could be possible candidates to supply Singapore with nuclear power based on their technological experience, said Dr Philip Andrews-Speed, a senior principal fellow at the National University of Singapore’s Energy Studies Institute.

“They have been working on nuclear power for decades. They could, in principle, tomorrow, make a decision (to build a reactor),” Dr Andrews-Speed said.

“But of course, as with everywhere in the world, this is a political issue. It is not purely energy policy,” he added.

The 2035 time frame EMA has set for Singapore’s energy imports may also be tight. Malaysia is thinking of building a new research reactor to replace its current 40-year-old model, according to a policy paper published this year, but no time frame has been set. It does not have a commercial plant.

The country did explore accelerating its nuclear power programme about 10 years ago, but progress has stalled under recent administrations.

Meanwhile, Indonesia wants to build its first commercial nuclear power plant by 2045.

Both Indonesia and Malaysia have said they will not export renewable energy, complicating Singapore’s plans to buy clean energy from its neighbours.

“Maybe Singapore is indicating it is accepting a wider choice of technologies,” Dr Andrews-Speed said, of Singapore’s decision to allow nuclear power in its latest call for import proposals.

He added that the cost of nuclear power over the next few years will depend on the type of technology used and the countries involved in building the reactors.

As it stands, nuclear power could cost over US$200 per megawatt-hour, much higher than solar and wind power, which caps off at around US$50 per megawatt-hour. Geothermal energy could reach close to US$100 per megawatt-hour, according to US-based asset manager Lazard.

Interest in nuclear energy worldwide has crept up recently, even outside its traditional supporters like France and China, amid high energy demand and fossil fuel prices. The United Kingdom wants to more than triple its capacity by 2050. Japan and the Philippines are planning to restart shelved plants.

Nuclear power is not in Southeast Asia’s regional green finance guidebook because of the high risks nuclear waste brings. The European Union considers nuclear energy projects green following a landmark vote this week, but its inclusion had attracted sizeable opposition from lawmakers and environmental groups.

Singapore does not have a nuclear power plant. In a scenario-planning paper released in March, EMA said the city-state could rely on domestic atomic energy to get its energy sector to net-zero emissions by 2050, if the world goes through a disorderly energy transition.

 

Longer runway

Singapore’s latest call for energy import proposals will be open for 18 months, till the end of 2023. The earlier round lasted only five months, and EMA said firms had asked for more time.

The agency said proposals from the earlier tranche will be automatically considered under the new round, which takes place under tweaked rules that allow consortiums to modify their plans after submitting initial papers.

EMA had earlier said it received 20 proposals in the earlier round, which detailed plans to import solar, wind, geothermal and hydropower from Indonesia, Malaysia, Thailand and Laos.

Has KFC found the secret sauce to circular packaging?

Has KFC found the secret sauce to circular packaging?

Fast food restaurants are big waste generators. However, the lack of viable sustainable alternatives to single-use plastic and the industry’s emphasis on cost and convenience means cheap, disposable foodware will be on their menus for some time yet.

Fast food chain KFC and Singapore-based sustainable foodware company TRIA are looking to disrupt the fast-food packaging industry with what they call the “world’s first” closed-loop single-use packaging pilot project.

In a six-month trial, one KFC restaurant in Singapore will switch its non-recyclable boxes, cups, and cutlery to those made from NEUTRIA, a rapidly degrading plant-based polyester developed by TRIA. The used packaging will be collected by TRIA and fed into their patented Bio24 digester, which turns it into compost within 24 hours.

Conventional plastic recycling faces many challenges in Singapore. Even if the food packaging is technically recyclable, segregating and cleaning it could potentially cost five times more than producing new packaging from scratch. Furthermore, most of the country’s plastic is incinerated. With little incentive to recycle or reduce plastic consumption, plastic waste is only expected to increase. Since 2017, plastic recycling rates have remained extremely low, usually hovering around 4 – 6 percent.

TRIA claims its product can remain relatively cost-competitive without compromising on sustainability. However, apart from ensuring the product’s economic viability, TRIA’s chief executive Ng Pei Kang says that sustainable foodware companies must give higher priority to their F&B partner’s operational needs if they are to make such packaging more widely accepted.

“I think it’s great that we are experimenting with [sustainable foodware like reusable cups], but we also need to empathise more with the food brands. How can KFC extend this to the 20,000 outlets they own without changing their operations? [With our model], they don’t need to hire more people or get new trash bins. If it’s not business as usual, it would be very tough [for restaurants to accept these new packaging products].” Ng said in an interview with Eco-Business.

During the pilot launch event at Shanaya Environmental Services on 21 June, KFC revealed that cost-competitiveness, design flexibility and operational resilience were some of the main factors which attracted them to TRIA’s product.

“Since 2017, we’ve been looking for new ways to reduce our use of non-recyclable packaging. We’ve previously considered edible spoons, but they could not meet our cost or operational requirements. However, TRIA was open to extensive redesigns and testing to ensure their product could withstand our daily operating needs and be collected and processed at an acceptable price point,” said Lynette Lim, general manager of KFC in an interview with Eco-Business.

Redesigning KFC’s mashed potato and coleslaw cup was particularly difficult for TRIA’s designers. Using the company’s plant-based material, the cup had to maintain its structural integrity when stacked, in addition to being heat and moisture-resistant. While it has yet to be tested in-store conditions, Lim cited this as an example of TRIA’s commitment to KFC’s operational standards.

For every tonne of NEUTRIA and food waste fed into the digester, TRIA claims that 200 – 300kg of compost can be produced. While the company has not yet secured an offtake agreement for its compost, it has signed memorandum of understandings (MOUs) with local rooftop farming company Comcrop, and Norwegian chemical and fertiliser company Yara International. Ng also highlighted how TRIA’s products and services can help these companies achieve their own business goals in a more profitable and sustainable way.

“Yara is looking to expand their regional presence here, and I think they are interested in our product because it could be a low-carbon source of fertiliser. In Europe, they have access to hydroponic power, which allows them to profitably produce low-carbon, green fertiliser. However, shipping this fertiliser to Asia is not realistic. That’s where we come in,” Ng explained.

In an upcoming bio-valorisation pilot, Yara hopes to produce bio-equivalent fertiliser from TRIA’s compost. Upon receiving TRIA’s product, Yara could theoretically adjust its nitrogen, potassium and phosphorus content to ensure that it is nutritionally equivalent to commercial fertilisers. Other than reducing costs, the closed-loop system allows the fertiliser to be traced, therefore building greater confidence in prospective buyers.

However, TRIA’s technology is not without drawbacks. The composting system hinges on TRIA’s ability to take ownership of and reprocess its post-consumer waste. Singapore is planning to introduce an extended producer responsibility (EPR) law for packaging by 2025, which could reduce public expenditure and the amount of waste sent to landfills. Nevertheless, Professor Seeram Ramakrishna, a mechanical engineering professor and chair of the National University of Singapore’s (NUS) Circular Economy Taskforce pointed out that achieving EPR has its difficulties.

 

What is extended producer responsibility (EPR)?
EPR is a policy approach where producers are given significant financial and/or physical responsibility for the treatment and disposal of post-consumer products.

 

“For EPR to work effectively, the presence of good waste management systems must be in place, including infrastructure to reprocess the waste. There should be a high level of compliance and enforcement,” explained Ramakrishna.

While Ng is confident TRIA can handle KFC’s in-store waste, he admitted that a system for managing takeaway waste remains elusive for now.

“Takeaway waste will still be sent to the public waste management system. However, the majority of packaging is used for dine-in purposes, and that’s where we are able to help,” Ng said.

In a previous interview with Eco-Business, Ng also professed that sourcing top talent for the sustainable food packaging industry remains a challenge. Furthermore, the hygiene and economic concerns of the pandemic have slowed the appetite for innovative new technologies like TRIA’s, he said. However, he stated that a partnership with one of the world’s most recognisable brands was an important step towards a circular packaging economy.

Big data, low carbon: how data centres innovate for sustainability

Big data, low carbon: how data centres innovate for sustainability

Data centres are well-known for being energy guzzlers because of the growth of digital demand. Worldwide, they consume an estimated 200 terawatt hours a year (TWh/yr), or nearly 1 per cent of global electricity demand.

That said, the energy consumption of data centres has not grown at the exponential rate of Internet traffic. This is due to the huge strides made in energy efficiency in data centres. Improvements in the efficiency of servers, storage devices and data centre infrastructure, as well as the move away from small data centres to larger cloud and hyperscale data centres, have all helped to limit the growth of electricity demand.

According to figures from a report by the International Energy Agency (IEA), from 2010 to 2020, the number of internet users worldwide has doubled and global internet traffic has expanded 15-fold. But global data centre energy use has been flat since 2015, at about 200 TWh/yr.

Globally, leading data centre operators have committed to carbon neutrality and science-based targets for emissions reduction by 2030. To achieve these goals, they have partnered with technology companies to develop ways of reducing energy consumption at all levels of operation – from direct-to-chip cooling to providing on-site prime power through alternative energy fuel cells.

 

New cooling solutions

One of the main areas of innovation is developing new solutions to cool data centres more efficiently as their capacity grows. Typically, cooling accounts for a large proportion of overall power consumption. Estimates from 2021 suggest that the figure ranges from 30 to 37 per cent.

Air cooling has been widely adopted in data centres since their inception. The basic principle of such systems involves circulating cold air around the hardware to dissipate heat.

But air cooling systems are struggling to keep up with the increases in the power density of racks. Thanks to new generations of central processing units (CPUs), rack power requirements have moved from below 20 kilowatts (kW) to up to 40 or 50 kW today, easily.

Air cooling systems have evolved to address higher densities, but there is a point at which air just does not have the thermal transfer properties to do so in an efficient manner. This has caused organisations to look into liquid cooling, as water and other fluids are up to 3,000 times more efficient in transferring heat than air.

Liquid cooling is available in a variety of configurations that use different technologies, including rear door heat exchangers and direct-to-chip cooling.

Rear door heat exchangers is the more mature technology, where a liquid-filled coil is mounted in place of the rear door of the rack. As server fans move heated air through the rack, the coil absorbs the heat before the air enters the data centre.

Direct-to-chip cooling integrates the cooling system directly into the computer’s chassis. A liquid coolant is brought via tubes directly to the chip, where it absorbs heat and removes it from the data hall. The warm liquid is then circulated to a cooling device or heat exchange.

One of the world’s largest data centre providers, Equinix, for example, is developing a new direct-to-chip cooling technology at their Co-Innovation Facility (CIF) located in the Washington DC area. Developed in collaboration with Zutacore, the system introduces a cooling fluid to an evaporator overlying the CPU to absorb heat directly, which in turn causes the liquid to evaporate and produce a constant temperature over the CPU.

 

Hotter temperatures

Some operators are challenging the thinking that data centres should be operated at low temperatures of 20 to 22 degrees celsius. There is evidence to support the running of data centres ‘hot’, i.e., increasing their temperature by 1 or 2 degrees Celsius, which improves efficiency without any significant sacrifices in system reliability.

In Singapore, the Infocomm Media Development Authority has been trialing the world’s first ‘tropical data centre’, to test if data centres can function optimally at temperatures of up to 38 degrees Celsius and ambient humidity up to or exceeding 90 per cent.

Running with simulated data, the trial would test how data servers react under various situations, such as peak surges or while transferring data, and in conditions such as with no temperature or humidity controls.

 

Using digital resources and analytics to optimise energy usage

Smart solutions monitoring energy consumption patterns allow data centres to configure the optimal use of their resources, as well as to identify and diagnose equipment problems and take steps to fix them. Software powered by artificial intelligence (AI) can also assist companies to better manage their infrastructure and maximise the utilisation of their CPUs.

In an interview with Fortune, Equinix’s chief executive Charles Meyer explained that AI is used in the company’s data centres to “anticipate where power needs to be applied, how cooling… needs to be done to improve the power usage efficiency of the facility overall”.

 

Using on-site lower-carbon energy sources

New cooling solutions and digital resources are offsetting the energy consumption from increasing data centre services. However, there remains the question of energy supply to the facility overall.

A totally carbon-free solution would involve locating a data centre beside a wind- or solar-generated renewable energy source, or purchasing 100 per cent green energy from the grid. But these may not always be feasible solutions. In Singapore, for instance, space constraints limit the use of solar energy, and wind conditions are not sufficient for wind power.

Alternatives include the use of fuel cells for primary power supply at data centres. Fuel cells generate power through electrochemical reactions using natural gas, biogas or LPG. Testing by Equinix at CIF indicates they are 20 to 40 per cent cleaner than gas-powered electricity generation.

When fuel cells are set up near data centres, there are even greater efficiencies. The generated electricity has less distance to travel and hence less energy is lost in the transmission process.

Equinix has deployed fuel cells at 15 of its facilities, including the carrier-neutral SV11 opened in San Jose in 2021, which utilises 4 megawatts (MW) of fuel cells for primary power production on site and can scale up to 20 MW of fuel cells.

Equinix is also part of a consortium of seven companies (including InfraPrime, RISE, Snam, SOLIDpower, TEC4FUELS and Vertiv) which launched the Eco Edge Prime Power (E2P2) project. E2P2 is exploring the integration of fuel cells with uninterruptible power supply technology and lithium-ion batteries to provide resilient and low-carbon primary power to data centres.

This work will also pave the way to transition from natural gas to green hydrogen (hydrogen produced using renewable energy) in fuel cells. Such advances are a step change towards sustainability where green hydrogen is available.

 

A holistic approach

Energy efficiency is crucial in determining future emissions in an industry that will continue growing in response to digitalisation and data consumption.

Besides energy efficiency, major data centre operators are interested in holistic sustainability gains that minimise carbon emissions. They consider how sustainable their supply chains are, total resource use and the company’s whole carbon footprint such as the embodied carbon in building materials.

Equinix, for example, has adopted a global climate-neutral goal by 2030 and has embedded decarbonisation actions across its business and supply chain.

Jason Plamondon, Equinix’s regional manager for sustainability in Asia-Pacific, says that the company is “well on (its) way to meeting (its) climate commitments, with over 95 per cent renewable coverage for (its) portfolio in FY21, maintaining over 90 per cent for the fourth consecutive year”.

He adds: “As the world’s digital infrastructure company, we have the responsibility to harness the power of technology to create a more accessible, equitable and sustainable future. Our Future First sustainability approach includes continuing to innovate and develop new technologies that contribute to protecting our planet.”

Singapore undertakes new voluntary commitments for ocean protection

Singapore undertakes new voluntary commitments for ocean protection

Singapore will be renewing the 10 voluntary commitments previously submitted at the first United Nations Oceans Conference (UNOC), and undertaking nine new ones for marine protection.

Three of the island state’s new commitments involve environmental research projects. These are related to sustainable management of marine fish populations, the use of solar energy to facilitate coral growth, and a Marine Climate Change Science programme.

Other new commitments seek to spearhead the shipping industry’s green transition, for example by incentivising ship owners to become more sustainable. The country wants to lead the charge on the maritime industry’s transition to energy efficient technologies and low or zero carbon fuels, said its foreign minister Vivian Balakrishnan, delivering an official statement at the UNOC in Lisbon, Portugal, this week.

“The challenges facing the ocean have increased with each passing year. We need to urgently scale up actions to collectively protect the ocean, and mitigate the impacts of climate change,” Dr Balakrishnan told member states.

 

What are voluntary commitments?
At the first UN Ocean Conference which took place in New York in 2017, member states agreed to create a list of commitments to further the implementation of Sustainable Development Goal 14, “Life Below Water”.

Ocean governance experts that Eco-Business spoke to, however, have expressed doubts about the efficacy of the voluntary commitments. The non-binding nature of these commitments raises questions about their ability to drive ambitious action for marine protection, in Singapore and beyond.

Dr Michelle Voyer, a researcher on ocean governance at Australia’s University of Wollongong, said that there can be problems evaluating whether the commitments have been implemented as planned, or if countries are succeeding in meeting their objectives.

“There is no mechanism that I am aware of at present which tracks the performance over time,” she said.

While submitters can update their commitments with a progress report on the Registry, this is not mandatory.

Globally, over 1900 voluntary commitments have been registered on the Ocean Conference Registry. These have primarily been made by governments and non-governmental organisations, but also include other stakeholders like United Nations entities, academic institutions, and the scientific community.

Based on the registry data, the Singapore government has submitted a total of 33 commitments since 2017, including the nine new ones. A check by Eco-Business found that progress updates have been submitted for at least 23 commitments, and seven commitments have been completed to date.

Ho Xiang Tian, co-founder of environmental advocacy group Lepak in SG, is confident that implementation would not be an issue for Singapore.

“The real question is whether the voluntary commitments can fulfill the needs of what the oceans require to thrive,” he said. “There is a global target to protect 30 per cent of Earth’s oceans by 2030, but I don’t think we are anywhere close to that.”

The 30 by 30 initiative seeks to designate 30 per cent of the world’s land and ocean as protected areas by 2030. More than 100 countries have publicly committed to this goal to date.

Land reclamation and dredging practices need better management: youth activists Kathy Xu, a marine conservationist from Singapore and founder of social enterprise The Dorsal Effect, said she was happy to see the focus on research on ocean species and sustainability in Singapore’s new commitments.

“The areas of the research sound promising, and I’m all for science based methods,” she said.

“However, the devil is in the details that we do not have,” Ms Xu noted. She added that she hopes the government will tap on the diversity of marine expertise in Singapore, including civil society stakeholders, “not just academic ocean conservationists”.

Alice Soewito, a member of environmental group Singapore Youth for Climate Action, said that while Singapore has made advances in the maritime shipping industry, the government could better manage land reclamation and dredging practices.

“These practices can result in chronic sedimentation that harm and kill corals, thereby impacting the rest of the marine ecosystem,” she said.

Since the 1960s, Singapore has adopted an aggressive approach of land reclamation to accommodate industrial activities and a growing population. The island’s land area has expanded by nearly 25 per cent over the last two centuries. The National University of Singapore’s Reef Ecology Lab has said that many coral reef ecosystems were “smothered” by past reclamation practices.

These environmental impacts extend beyond Singapore’s borders. A 2010 report by international NGO Global Witness claimed that sand mining practices in Cambodia’s Koh Kong province, from which Singapore imported sand up till 2016, severely depleted local fish and crab stocks.

Malaysia and Indonesia banned sand exports to Singapore in 1997 and 2007 respectively due to environmental concerns.

On a global scale, Dr Voyer pointed out that many current commitments have a strong emphasis on research and science, as well as capacity development.

“Of course we always need to be improving the knowledge base,” she said. “But I would like to see greater emphasis on recognising the existing capacity within many coastal communities and amongst ocean stakeholders.”

“This includes engaging with local knowledge, and being bold in trying ideas put forward by the communities,” said Dr Voyer.

 

Negotations underway for new global ocean treaty

This year’s Ocean Conference, which took place from 27 June to 1 July, sought to scale up ocean action with a specific focus on science and innovation. Member states adopted a political declaration reaffirming their commitment to ocean conservation.

While this declaration is not binding, it lays the political foundation for an upcoming legally binding instrument — the Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction, colloquially known as the BBNJ Treaty. Singapore serves as the current president of the Intergovernmental Conference and will help to facilitate the fifth round of negotiations taking place in August this year.

In his speech, Dr Balakrishnan called on all delegations to “work towards the conclusion of an ambitious and future-proof BBNJ treaty as soon as possible”.

Singapore airlines to launch sustainable aviation fuel credits

Singapore airlines to launch sustainable aviation fuel credits

Earlier this week, Singapore Airlines (SIA) announced that it would launch the sale of sustainable aviation fuel (SAF) credits in July 2022. The move is part of a pilot initiative of the Civil Aviation Authority of Singapore (CAAS) and global investment company Temasek to advance the use of SAF in Singapore.

he credits will be available for purchase to corporate customers and individual passengers as well as air freight forwarders. On offer will be a total of 1,000 SAF credits, corresponding to 1,000 tonnes of neat sustainable fuel uplifted from Singapore Changi Airport, to be blended with conventional jet fuel.

Every credit purchased is expected to reduce CO2 emissions by 2.5 tonnes, for a total of 2,500. Now, this might be a mere fraction of the emissions that the regular fuel still needed – both for regulatory reasons and a lack of supply – is responsible for. However, aviation isn’t going anywhere, neither is climate change, and the transition toward sustainable fuels has to start somewhere. Ms Lee Wen Fen, Senior Vice President Corporate Planning, Singapore Airlines, said,

 

“As we progress with the SAF pilot in Singapore, we can now offer more opportunities for our corporate customers and travellers to mitigate their carbon emissions using SAF credits, which are registered and accounted for within the RSB Book & Claim System. This will help to accelerate and scale up the collective adoption of SAF, reinforcing our commitment to achieve net zero carbon emissions by 2050.”

By purchasing SAF credits, customers will help stimulate the demand for SAF, which in turn will increase supply. As it becomes more available, even though they are by no means a perfect solution, sustainable fuels will begin to make more of a dent in aviation’s carbon footprint.

 

Sustainable Air Hub Blueprint in the works

Singapore has its sights set on becoming a South East Asia SAF hub. As part of its Green Plan 2030, Changi has ambitions to become one of the early movers in the region, thus far lagging behind the US and Europe when it comes to production and uptake. Mr Han Kok Juan, Director-General, CAAS, stated,

 

“The creation of a trusted and vibrant marketplace for the sale and purchase of SAF credits in Singapore will help support the adoption of SAF which is essential for the decarbonisation of the aviation sector and a key element of the Singapore Sustainable Air Hub Blueprint which CAAS is developing.”

Combining offsets and SAF

From Q4, all of SIA’s customers will be able to purchase a mix of SAF credits and carbon offsets as part of the SIA Group Voluntary Carbon Offset Programme, through a partnership with Climate Impact X, a global marketplace and exchange for high-quality carbon credits. Mr Mikkel Larsen, Chief Executive Officer, Climate Impact X, commented,

 

“SAF credits can help to spur adoption by enabling competitive price discovery, and channelling finance towards projects that can drive the use of sustainable fuels at the scale necessary to support decarbonisation in the aviation sector. Through CIX’s ongoing efforts to curate verified projects for our platforms, we aim to increase access to quality carbon credits worldwide and drive environmental impact at scale.”

The workplace of the future: smart, sustainable, holistic

The workplace of the future: smart, sustainable, holistic

The workplace as we know it has evolved dramatically during the Covid-19 pandemic, expanding into our homes and complex digital-physical spaces. As organisations and their employees continue to navigate hybrid working arrangements this year, how can technology help to shape green and conducive workplaces of the future?

Many new innovations are aimed at helping workplaces save energy. While energy efficiency may not be the snazziest of climate solutions, it remains a potent and cost-effective way to slash emissions without major reworks of existing infrastructure. The International Energy Agency (IEA) has projected that low-cost measures, such as better ventilation and LED lighting, if implemented globally, could slash 3.5 gigatonnes worth of carbon emissions a year.

The savings would amount to 40 per cent of the emissions that need to be abated to limit global warming to 2 degrees Celsius. With the increased focus on climate mitigation, energy efficiency solutions for the built sector is now a US$340 billion market globally that is set to grow by over 8 per cent through 2027.

In addition, in Singapore, energy efficiency incentives like the Green Mark Incentive Scheme are encouraging companies to pursue smart, sustainable and predictive solutions in the workplace. Companies are paying closer attention to their carbon footprint to support sustainability goals, and this requires more tools to monitor and optimise utilities consumption.

These tools usually come in the form of building intelligence systems, such as SP Digital’s GET Control. The system uses AI and IoT to optimise and regulate air-conditioning and maximise energy efficiency in real-time, based on changes in occupancy, current weather conditions and forecast data. The smart damper system, for example, divides large open-plan office spaces into micro-zones to enable better air-flow distribution and control. With predictive intelligence working together with all the sensors and smart dampers, data is sent wirelessly to a central control unit that recommends and adjusts the dampers dynamically such that the desired temperatures are met, making the office energy efficient and comfortable.

Clement Cheong, SP Digital’s vice president of sales and customer operations, says that GET Control responds to the needs of corporate real estate owners and commercial landlords in Singapore.

“Landlords are seeing more occupants coming into work and at different times,” he says. “They need to adapt their buildings and systems to cope with this change dynamically. For example, they do not need as much cooling or fresh air supply at non-peak or low occupancy periods.”

Moreover, he adds that the pandemic has also made employees even more conscious of indoor environmental quality. “They want to have visibility into IAQ (Indoor Air Quality) and the building’s measures to monitor and improve IAQ. Even though occupants may spend less time in the office, they want a better, healthier indoor experience.”

He explains that currently, building owners or tenants have limited visibility into indoor air quality in offices and limited ability to intelligently control it. Traditional air side control and management technologies tend to be “reactive”, that is, facility managers make adjustments when occupants complain of any indoor thermal discomfort. Because such technologies do not take into account dynamic changes in ambient temperatures, they are not as energy efficient as a system with real-time tracking capabilities like GET Control.

He shares a case study from an educational institution in Singapore, where facility managers were faced with frequent occupant complaints about hot and cold spots in the office. Besides the fact that facility managers had to make time-consuming manual adjustments, the building’s cooling efficiency was poor, resulting in high energy use and carbon emissions. When SP Digital’s GET Control was deployed, the site saw more than 30 per cent airside cooling energy savings, enhanced thermal comfort and indoor air quality for employees, and improved operations and productivity.

On a larger scale, some multinational corporations are leading the way in greening their offices, and their examples might provide insights into the future of the sustainable workplace. One of them is Meta, which operates the social media platform Facebook and aims to achieve a 50 per cent reduction in carbon by 2030. At its 260,000 square-feet office in Singapore, spread over four floors at Marina One Tower, this target has translated into environmental control systems that use the latest in automated sensor technology, which can optimise even the smallest indicators of energy efficiency. Numerous sensors are in place to measure temperature, air, light and motion open spaces, meeting rooms and lifts.

Apart from office management, Meta Singapore also uses technology to assist employees to adopt carbon reducing behaviours, and, while in the workplace, to holistically analyse their carbon footprint across the product supply chain, recycling, water and waste management.

Looking ahead globally, the journey to make buildings more sustainable will be a long one. Currently, the built environment is responsible for nearly 40 per cent of all greenhouse gas emissions in the world. According to a report by the International Energy Agency (IEA), the 2020 pandemic caused a drop in the buildings sector carbon emissions, followed by a moderate rebound in 2021, but buildings are not on track to achieve carbon neutrality by 2050.

In Singapore, energy efficiency remains a core tenet of the city-state’s decarbonisation pathway, even as longer-term solutions such as carbon capture and clean energy imports are being considered for the next few decades. Power generation firms are provided subsidies to upgrade their turbines and software; a similar fund is in place for building owners to buy more efficient air-conditioning systems and install motion sensors that automatically switch off appliances when not needed. Buildings contribute close to 15 per cent of Singapore’s national emissions — the high fraction resulting from the almost complete urbanisation of the island-state.

As part of its efforts to reach net-zero emissions around 2050, the government wants 80 per cent of buildings in Singapore – both old and new – to adopt energy efficiency measures by 2030, up from 50 per cent today.

There is growing awareness among businesses that greening their offices makes economic and environmental sense. The Singapore Building and Construction Authority’s Green Mark Incentive for Existing Buildings – a $100 million fund started to co-sponsor the adoption of energy-efficient technologies in existing buildings – has been fully committed, as has a separate $50 million fund which does the same for small and medium enterprises.

This suggests that more landlords in Singapore understand that the initial outlays of such green investments may be high, but returns in the long run justify the cost, given the changes in expectations of workplace experience, energy efficiency and sustainability in post-pandemic times.
