Lidl launches city-wide drinks packaging recycling scheme

Posted on February 13, 2024 by dishanth

Shoppers will be able to deposit any single-use drinks packaging made from either PET plastic or aluminium, between 100ml and three litres in size. Barcodes must be attached and readable.

Collected packaging will be sent for recycling. Lidl is aiming to capture at least 10.5 tonnes of material every month.

The launch of the scheme is intended to go some way to preparing customers for Scotland’s nationwide deposit return scheme (DRS) for drinks packaging, which was due to launch last August but was delayed until March 2024.

Further delays could yet be announced due to backlash from some retailers, plus the fact that a UK-wide DRS is not due to launch until early 2025 at the soonest.

DRS initiatives see a levy placed on beverages, which customers can only claim back after returning their used packaging to a certified collection point for recycling.

But Lidl has elected not to add a levy to its beverages at present. Instead, customers will receive a 5p reward for every bottle or can returned, with no limit on the amount that each person can claim. They can receive the rewards as either a voucher for money off their next shop, or as a donation to Lidl’s charity partner in Scotland, STV Children’s appeal. The appeal supports children in poverty with education, mental health care, social activities and necessities like food and clothing.

Lidl GB’s chief commercial officer Richard Bourns described the initiative as “a win-win for all”.

He said: “We’re on a mission to eliminate all unnecessary waste, and with over 95% of our own-brand packaging now recyclable, reusable, or refillable we’ve been making great progress. We know that Lidl shoppers share this passion, and we hope that utilising this infrastructure, which might otherwise have been left dormant, will help to make recycling their cans and bottles even more convenient for them.”

Apple touts its first carbon-neutral products

Posted on September 15, 2023September 15, 2023 by dishanth

The Apple product launch event is a highlight in the calendar for anyone working in digital technology. At its headquarters in California on Tuesday (12 September), Apple launched its new iPhone 15 series and ninth Apple Watch series, plus its second iteration of Apple Watch Ultra.

Apple has stated that the new Apple Watch lineup consists solely of carbon-neutral products. It has delivered a 75% reduction in the life-cycle emissions of its watches since 2015 due to investments in clean energy procurement, energy efficiency and reducing transport emissions.

Product re-design and supply chain engagement have also driven reductions in emissions. Each of the watches includes at least 30% recycled or renewable material by weight, for example, including a 100% recycled aluminium casing and 100% recycled cobalt in the battery.

It bears noting that Apple’s carbon accounting for the carbon-neutral claim also covers consumer use of products.

In a statement, the firm said: “Electricity for manufacturing and charging devices represents the largest source of Apple’s emissions across all product lines. To address the latter, Apple has committed to invest in large-scale solar and wind projects around the world. For the carbon-neutral Apple Watch models, the company will match 100% of customers’ expected electricity use for charging.”

To address the 25% residual emissions associated with the watches, Apple will invest in carbon credits “primarily from nature-based projects”.

It has stated an intention to ensure that carbon credits are “high-quality” by assessing whether they represent additional, measurable, quantified and permanent carbon removal. Another key requirement is that the credits are not double-counted.

A surprise move?

Science reporter Justine Calma has argued that Apple’s announcement distracts from the company’s overall impact on climate and the environment. She said a far more important measure of the firm’s work on climate will be whether it delivers its 2030 and 2050 goals.

Apple achieved carbon neutrality for its global corporate operations in 2020 and subsequently pledged to deliver a carbon-neutral value chain by 2030.

It is seeking to reduce emissions upstream and downstream by at least 75% on 2015 levels, only relying on offsetting for a maximum of 25% of residual emissions.

Apple has described this ambition as “aggressive”. Meeting this goal will require increased investments in decarbonising national electricity grids; low-carbon transport innovations and transport efficiencies; product re-design and material innovation.

On the latter, Apple is working to switch to 100% recycled cobalt in batteries, plus 100% recycled tin soldering and gold plating in circuit boards, by 2025. It is also ending the use of leather across all product lines with immediate effect, switching to a new ‘FineWoven’ textile made from 68% post-consumer recycled fibres.

Apple continues to use the language of carbon neutrality despite a forthcoming crackdown on this kind of claim in the EU. Lawmakers voted in May to support a new directive that will prevent companies from badging consumer goods as ‘carbon-neutral’ or ‘carbon-negative’ if they use offsetting. Only time will tell how Apple will choose to communicate its climate efforts to customers in the EU once this directive comes into force.

Charging port changes

Another sustainability-related facet of Apple’s latest product launch is the switch from the Apple-exclusive ‘lightning’ charging port to a USB-C port for the iPhone 15.

The change is being made because the EU is mandating that all electronic devices sold within the bloc from 2024 use USB-C charging, in a bid to reduce the e-waste generated by the need for each home to have an array of different chargers.

In the long-term, the result is likely to be waste reduction. But, in the coming months, there are concerns that there will be a spike in the discarding of Apple ‘lightning’ cables. It is estimated that one-quarter of European residents own an iPhone.

The Ban on Plastic Water Bottles at LAX

Posted on September 5, 2023 by dishanth

Did you know that over 481 billion plastic bottles are used worldwide every year? Americans purchase, on average, 50 billion water bottles per year. This averages about 13 bottles per month for every person. The US, China and Indonesia are the largest consumers of plastic water bottles. Purchasing plastic water bottles in these countries buying, plastic water bottles are seen as a luxury whereby the water is regarded as “healthier” or has a better taste. Countries in the Global South together represent roughly 60 percent of the market. These countries are almost dependent on plastic water bottles due to the lack of reliable access to safe tap water.

The issues surrounding the overconsumption of plastic water bottles include the fact that the groundwater extracted to help fill the billions of plastic bottles a year poses a potential threat to drinking water resources. Moreover, the industry’s growth helps distract attention and resources from funding the public water infrastructure needed in many countries. Using plastic water bottles harms the planet because most plastic gets thrown into landfills. In fact, only 9 percent of the plastic from these bottles is recycled, which is only getting lower due to China no longer accepting US plastics.

Despite the adverse effects plastic, especially plastic water bottles, have on the planet, there is no sign of these sales slowing down. Experts are saying that plastic water bottle sales are expected to rise by 2030.

To reduce the use of plastic water bottles, at least in the US, the Los Angeles Airport (also commonly known as LAX) is banning the sale of these single-use plastic water bottles. Over 9 million plastic water bottles were sold at LAX alone in 2019, which averages more than 24 000 bottles a day. The LAX plastic water bottle ban went into effect on June 30, 2023.

The LAX plastic water bottle ban includes concessionaires, restaurants, lounges, vending machines and events happening at the airport. Only single-use water bottles made from recyclable aluminium, cartons or glass may be sold at the airport. The airport encourages visitors to bring their own reusable water bottles and use the water bottle refill stations located in the various terminals. The LAX plastic water bottle ban does not include other beverages sold in plastic bottles or bottled water from flight services on aircraft. This is something that might change in the coming years.

This new policy is part of the Los Angeles World Airports (including LAX and Van Nuys Airports) Sustainability Action Plan, which targets a zero-waste future. The plan is to make these airports zero waste by 2045. The LAX plastic water bottle ban is only the second airport in the world to ban the sale of single-use plastic water bottles and follows San Francisco International Airport, which placed its ban in 2019. In 2021, San Francisco extended the ban to include other types of beverages.

The LAX plastic water bottle ban is only part of a bigger push for sustainability. Los Angeles World Airport has a long history of committing to environmental sustainability. In the early 1990s, it introduced waste diversion and recycling programs at its airports and in 2007, it adopted one of the first sustainability plans for any airport in the nation. Reducing waste and eliminating single-use plastics are important goals for the Los Angeles World Airports and the City of Los Angeles. The LA City Green New Deal calls for all city departments to phase out single-use plastic by 2028 and achieved 100 percent waste diversion by 2050.

It’s impressive that no other airports have taken these initiatives yet. But we know that California is a leader in the sustainability movement. Hopefully, the LAX plastic water bottle ban will encourage other airports around the US and even across the globe to take part in this initiative and reduce dependence on plastic.

The ShAPE Aluminum Recycling Method Could Change The Industry Forever

Posted on July 25, 2023July 25, 2023 by dishanth

Our Lives are Built with Aluminum

Aluminum is one of the most widely used industrial materials available today. It exists in our cars, our boats and ships, and in the buildings we live in.

In the EV industry, the importance of aluminum cannot be overstated, given that it is required to create the casing of the batteries that power the vehicle. The benefits of aluminum come down to its strength and its weight.

However, mining the raw materials that go into aluminum harms our environment. Bauxite is a mineral used in the creation of aluminum, and the mines that pull the ore out of the ground are responsible for acres of deforestation, water pollution via the Bayer process, air pollution due to the temperatures required to forge it, and other environmental impacts.

The aluminum manufacturing industry has been taking steps to reduce its reliance on new aluminum, though current technology still requires a sizeable amount of new aluminum to recycle scrap aluminum.

However, a new technology has been created that could eliminate that need entirely. This is how the ShAPE aluminum recycling process could change how we procure aluminum.

What is it, and How Does it Work?

The Shape aluminum recycling (Shear Assisted Processing Extrusion) process is an innovative new method of recycling aluminum created by the United States Department of Energy’s Pacific Northwest National Laboratory in Richland, Washington.

This process was created primarily for the automotive industry so as to reduce the reliance on freshly created aluminum and cut the environmental impacts of creating EVs. The process was also created in collaboration with Magna, a leading mobile technology company.

This process could reduce 50% of the embodied energy and 90% of the carbon dioxide emissions output by reducing the amount of aluminum required by mining. The ShAPE aluminum recycling process is unique because it doesn’t require any pre-heating step to remove impurities in the scrap aluminum.

It works by rotating the aluminum on a die in the ShAPE aluminum recycling machine while being pushed through a small opening. Combining rotation and deformation ensures that the metal elements are distributed evenly, eliminating the need for a pre-heating process.

In testing to ensure that the aluminum produced by ShAPE aluminum recycling is as strong as they think, they used electron microscopy and electron backscatter diffraction to create an image of the placement and microstructure of the metal particle within the finished product.

They did this test using aluminum 6063, also known as architectural aluminum. They found that this aluminum product was uniformly strong and lacked manufacturing defects that would otherwise cause the aluminum to fail in its application.

They also found no impurities in the metal, which is important due to the fact that the metal they used was entirely recycled, and raw scrap metal is full of impurities.

While incredibly promising, EV technology currently relies on industries and industrial methods that are incredibly damaging to the environment. The EV industry is working hard to eliminate this contradiction of being eco-friendly yet requiring damage to the environment to be created.

With the ShAPE aluminum recycling method, there could be significant changes to multiple industries, not only the automotive industry. A lead researcher on the project, Scott Whalen, said, “We are now working on including post-consumer waste streams, which could create a whole new market for secondary aluminum scrap.”

While current methods are being used, the environmental damage cannot be understated. However, in the future, using this new method, things could change forever for the better.

Apple aims for 100% recycled cobalt in batteries by 2025

Posted on April 18, 2023April 21, 2023 by dishanth

Apple has unveiled plans to increase the use of recycled materials in its products, with a new target of using 100% recycled cobalt in all Apple-designed batteries by 2025.

The tech giant will also aim to use entirely recycled rare earth elements in magnets for its devices and 100% recycled tin soldering and gold plating in all Apple-designed printed circuit boards by the same year.

“Every day, Apple is innovating to make technology that enriches people’s lives, while protecting the planet we all share,” said Tim Cook, Apple’s CEO. “From the recycled materials in our products, to the clean energy that powers our operations, our environmental work is integral to everything we make and to who we are. So we’ll keep pressing forward in the belief that great technology should be great for our users, and for the environment.”

Reducing Apple’s carbon footprint

The announcement is part of Apple’s broader efforts to reduce its carbon footprint and become more environmentally friendly.

In 2022, the company significantly expanded its use of recycled metals, with over two-thirds of all aluminium, nearly three-quarters of all rare earth materials, and more than 95% of all tungsten in Apple products sourced from 100% recycled material.

Apple’s rapid progress in this area brings the company closer to its ultimate goal of making all products with only recycled and renewable materials and advances its aim to achieve carbon neutrality for every product by 2030.

“Our ambition to one day use 100% recycled and renewable materials in our products works hand in hand with Apple 2030: our goal to achieve carbon neutral products by 2030,” said Lisa Jackson, Apple’s vice president of Environment, Policy, and Social Initiatives. “We’re working toward both goals with urgency and advancing innovation across our entire industry in the process.”

If Apple is able to achieve this goal, it will show major steps towards achieving a more sustainable future for the company.

Decarbonizing Aluminum; a Low-Carbon Future for a Versatile Metal

Posted on March 28, 2023March 28, 2023 by dishanth

What is aluminum, and what is it used for?

Aluminum is a silvery-white, soft, nonmagnetic metal. It has good electrical and thermal conductivity and is used in many products, from cars and airplanes to packaging, foil and cans. It is a highly versatile metal, but many people don’t realize that it’s also one of the most carbon-intensive metals to produce.

Because it is used in so many diverse applications, the aluminum industry has a big environmental footprint. Aluminum production emits about 1% of global man-made greenhouse gas emissions. Most of these emissions come from using fossil fuels to make aluminum oxide (alumina), which is then reduced to aluminum metal in smelters.

The aluminum industry is working on ways to reduce its emissions. One promising technology is “carbon-free” or “green” aluminum production. This process uses renewable electricity – instead of fossil fuels – to produce alumina, which can then be turned into aluminum metal using existing smelting technology.

Several companies are already using or testing this technology, including Rio Tinto, Alcoa, Hydro and China’s Chalco. These companies are betting that carbon-free aluminum will be in high demand from industries and consumers who want to reduce their emissions footprints.

Why is aluminum production carbon-intensive?

There are two main reasons why aluminum production is so carbon-intensive. First, alumina, the raw material used to produce aluminum, is derived from bauxite ore, typically found in tropical regions. The process of mining and refining bauxite ore releases large amounts of carbon dioxide into the atmosphere.

Second, smelting alumina to produce aluminum metal emits significant amounts of carbon dioxide. Smelting is responsible for approximately two-thirds of the total emissions associated with aluminum production.

How will the industry decarbonize aluminum?

The most common method of producing aluminum involves the electrolysis of alumina in a high-carbon anode, which results in significant emissions of greenhouse gases. The industry is developing low-carbon technologies to reduce or eliminate these emissions.

Another promising technology is using renewable energy to power the electrolysis process. This would significantly reduce the carbon footprint of aluminum production. Solar, wind, and hydroelectric power can all power these processes while significantly reducing or eliminating emissions.

Recycled aluminum requires less energy to process and emits far less carbon dioxide than virgin alumina.

Each of these options comes with its challenges, but the aluminum industry is committed to finding ways to reduce its environmental impact. For example, Rio Tinto is investing in research into new smelting technologies that could significantly reduce emissions. Alcoa is working on a project to power its operations with renewable energy from forest biomass waste.

Will the quality of low-carbon aluminum be lower?

Decarbonized aluminum is made using low-carbon methods, which results in a lower carbon footprint. However, some worry that this type of aluminum will be of lower quality than regular aluminum.

No evidence suggests that decarbonized aluminum is any less strong or durable than regular aluminum. In fact, it may even be of higher quality due to the extra attention to the manufacturing process and modern innovations in the process. Low-carbon methods often result in a cleaner and more pure product.

A study by the International Aluminum Institute found that, when using best practices, there was no significant difference in the quality of low-carbon aluminum and regular aluminum. The study found that, in some cases, low-carbon aluminum had superior properties.

This is because environmental regulations are becoming more stringent, forcing producers to innovate and find ways to reduce their carbon footprint without compromising on quality.

Waitrose replaces small glass wine bottles with cans in bid to cut carbon

Posted on January 16, 2023 by dishanth

The supermarket chain, owned by the John Lewis Partnership, announced the change this week. Customers will begin seeing the wine lines in the new packaging from Sunday (15 January).

A total of 19 small wine lines are set to be housed in aluminium cans rather than glass bottles. Waitrose claims that the move will reduce the weight of its wine packaging used annually by 320 tonnes, while also reducing carbon emissions across the value chain.

As the cans are lighter than the bottles, transport emissions are set to be reduced. Emissions reductions are also expected in the upstream value chain. Waitrose’s own life cycle analyses have concluded that an aluminium can will create less than half the amount of CO2e across its lifecycle than equivalent glass bottles.

The new cans can be recycled in with household mixed recycling collections. Aluminium is regarded as an infinitely recyclable material; unlike plastics, the quality of the material does not decrease when it is mechanically recycled.

For these environmental reasons, and for reasons relating to cost and convenience, Waitrose has already moved to canned formats for products including craft beers and cocktails.

Waitrose’s beer, wine and spirit bulk sourcing manager Barry Dick said he hopes the move in the wine aisle will “encourage suppliers to continue to develop a diverse and exciting range of wines in cans”.

Waitrose is notably working towards a 2035 net-zero target for its entire value chain. The John Lewis Partnership moved its 2050 target forward by 15 years back in October 2020. It subsequently joined the UN-backed Race to Zero campaign. John Lewis Partnership is planning to set verified science-based climate targets covering emissions from all scopes, including Scope 3 (indirect) emissions in the supply chain, in the coming months.

Tackling vape waste

The news on the wine packaging comes shortly after Waitrose announced a decision to end sales of single-use vaping products. The retailer had already implemented a ban on sales of single-use vape pens but built upon this by delisting imitation cigarettes.

Waitrose said in a statement that it was concerned about the appeal of single-use vapes to young consumers and about the environmental impact of the products, which contain plastic and lithium and are often littered. Previous research from Material Focus revealed that at least 1.3 million disposable vapes are thrown away in the UK every week – equivalent to two every second. Recycling systems do not yet exist for these products.

Jaguar Land Rover turns to recycled aluminium to cut manufacturing CO2

Posted on August 24, 2020 by dishanth

The firm’s £2m REALITY project is developing high-grade aluminium from a blend of waste cans, bottle tops, and scrap vehicles

Jaguar Land Rover has developed an innovative process enabling it to recycle old aluminium cans, bottle tops, and end-of-life vehicles into brand new, premium cars, in a move it estimates could cut CO2 emissions from its manufacturing by more than a quarter.

Co-funded by the government’s innovation agency Innovate UK, the process was developed in partnership with Brunel University as part of a £2m project called ‘REALITY’, the British carmaker announced on Friday.

Engineers mixed recycled aluminium parts with a reduced amount of primary aluminium to form a new prototype alloy, which it said matches the quality of the materials currently used by the firm in its car manufacturing.

The project involved establishing a system for the recovery of the automotive-grade aluminium used to manufacture its products, the firm explained. Vehicle scrap is typically exported overseas, but the project drew on new separation technology to upcycle material from old cars so it could be blended with aluminium waste, thereby reducing the need for virgin aluminium.

Jaguar Land Rover said it was using pre-production of its Jaguar I-PACE electric vehicle prototypes to test the process, estimating it could potentially reduce alloy production CO2 emissions by up to 26 per cent compared to the current automotive grade.

“This project has allowed us, for the first time, to recover premium automotive-grade aluminium from scrapped vehicles and re-use its unique properties,” said Gaëlle Guillaume, REALITY lead project manager at Jaguar Land Rover. “The potential of this on the production process is a reduction in CO₂impact as well as helping us re-use even more aluminium. As we move into an autonomous, connected and electrified future, with the potential of shared fleets being de-commissioned en masse, it could allow Jaguar Land Rover to engineer this closed loop recycling alloy into tight production schedules to further improve efficiency and environmental benefits.”

Post-consumer recycled aluminium is widely used in products such as cans, food trays, bottle tops, and foil, but is has only more recently started to be utilised in automotive manufacturing. Recycled aluminium uses around 90 per cent less energy to produce compared to raw material production, according to the Aluminium Association.

The REALITY project forms part of Jaguar Land Rover’s recently announced sustainability strategy Destination Zero, through which it is aiming to become a zero emissions, zero accidents, and zero congestion company.
