Lidl launches city-wide drinks packaging recycling scheme

Posted on by dishanth
Lidl launches city-wide drinks packaging recycling scheme

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.”

Absolut Vodka in Paper Bottles

Posted on by dishanth
Absolut Vodka in Paper Bottles

Over 50 years ago, we were introduced to the concept of box wine – a wine that came in a box with a collapsible bag inside. The invention gained popularity because it was cheaper than other wines and spirits. Adding the integral tap in the bag made it easier to pour a glass of wine and store it. From an environmental standpoint, boxed wine is recyclable and easier to transport. Although glass is recyclable, it requires a lot of energy to produce and transport.

Switching to cardboard is less energy-intensive to produce and is a lot lighter in comparison to transport. Although boxed wine has been associated with being a cheaper quality wine, the quality has improved significantly over the years, with many winemakers packaging their products in boxes.

If wine can be packaged more sustainably, what about other types of alcohol? Swedish company Absolut Vodka wants to switch from glass bottles to paper bottles. As part of a pilot project, Absolut has made bottles out of 57% wood fibres certified by the Forest Stewardship Council. To prevent the liquid from leaking through, the bottles contain an integrated moisture barrier made from recycled plastic.

This pilot project is part of a collaboration with Paboco and the Pioneer Community. Paboco is a paper bottle company working towards creating the world’s first 100% bio-based and recyclable paper bottle. The paper bottle is recyclable as paper packaging and can be designed to hold many different products, from soda to sun location. The company has partnered with L’Oreal, the Coca-Cola Company, Procter & Gamble and many others to help introduce smarter and more sustainable packaging solutions into more significant markets.

Paboco is no stranger to packaging alcohol in paper bottles. They have been successful with beer company Carlsberg with their Fibre Bottle, made out of plant-based PEF polymer lining. The material is compatible with plastic recycling systems and can degrade in nature. The PEF, which is made out of natural raw materials, protects the taste and fizziness of the beer, and the outer shell helps to keep the beer colder for longer compared to cans or glass bottles.

Absolut Vodka has been testing these paper bottles for over a decade, and they are finally launching 500-millilitre paper bottles in select Tesco stores in Manchester, in the UK. The city of Manchester was chosen as a testing site because it had the recycling infrastructure to handle the bottles. Absolut also found that Manchester had higher household recycling rates than any other region in the UK.

Much like how wine boxes are lighter and less energy-intensive to transport, Absolut will calculate the carbon footprint of the paper bottles, which will be significantly lighter than their traditional glass bottles. The company is also collecting feedback from consumers, retailers and distributors and will use their findings to make necessary adjustments. They will also be working on developing ways to make the bottles from more than 57% paper and achieve a 100% paper bottle target.

While glass is a better option and can be used infinitely, compared to plastic bottles, it is pretty costly to recycle. Glass can only be recycled in furnaces that use high energy to reach high heat, increasing pollution. The switch to paper bottles could have a significant impact on the emission that comes from the food and drink industry. While Absolut Vodka is only one of many alcohol companies, it could be the inspiration needed to make the switch. We might see our liquor stores go from clanky, heavy glass bottles to lightweight paper ones in the near future.

Greenwashing is out: companies need to get serious about their sustainability journey

Greenwashing is out: companies need to get serious about their sustainability journey

Businesses are increasingly being held accountable for their environmental and social impact. And Siegwerk, a global provider of inks and coatings for packaging, has taken a leading role in driving sustainability within the sector. The company is committed to producing packaging solutions to drive a circular economy for the industry, and supporting sustainable transitions along its supply chain.

Like many companies, Siegwerk has taken an incremental approach to expanding its sustainability strategy. “We started our sustainability journey by looking at how our products could better enable a circular economy,” says Alina Marm, Global Head of Sustainability and Circular Economy at Siegwerk. “That laid the groundwork for us to launch an entire new strategy on sustainability with a broad scope, covering carbon neutrality targets and diversity as a quantifiable target, but also looking at the conditions in our supply chain and creating transparency around these conditions in order to continuously improve.”

For Marm, the three primary aspects that define sustainable packaging are true circularity, carbon neutrality and fairness in the supply chain: “Carbon neutrality meaning zero emissions, and fairness in the supply chain meaning that there’s nobody who suffers as a result of your business practices.”

There is an increased need for transparency around companies’ sustainability data. Consumers are more educated about greenwashing and will no longer just take companies at their word when it comes to sustainability claims. Special interest groups such as NGOs are also publicly highlighting discrepancies between company commitments and performance.

“There is a huge regulatory push to bring sustainability reporting on par with financial reporting. And this is a game-changer. It’s going to make it much easier for consumers to look up data and make decisions about which products to buy and which companies to support,” Marm says.

But this is one area that is severely lagging. A survey conducted by Deloitte in April 2022 revealed that only 3 per cent of consumer companies say they produce sustainability data that is as accurate and verifiable as their financial data. Siegwerk is one of the first companies in its sector to commit to reporting on the carbon footprint of its products. “There is no option but to embrace sustainability holistically,” says Marm. “It’s not just about doing the right thing, it’s also about remaining competitive and future-proofing your business.”

The Power of Responsible Sourcing

Posted on by dishanth
The Power of Responsible Sourcing

Climate change, circular economies, ESG and sustainability have all become business priorities over the past few years, with global supply chains sitting right in the middle of these issues – both as a major contributor to the problem and as an area of focus for improvements. Businesses must, therefore, purchase materials and products from companies that can show that they have good sustainability practices, from both a labour and manufacturing point of view.

The benefits of responsible sourcing and sustainable packaging

Responsible sourcing has been shown to influence consumers buying decisions, with studies suggesting that up to 70% of consumers would pay more for sustainably-produced goods. Businesses must therefore meet the increasing demand from consumers for products that are both environmentally and socially responsible.

Yet businesses are still learning when it comes to improving their responsible sourcing process, with Richard Howells, Vice President of Solution Management for Digital Supply Chain at SAP, describing it as an “evolving landscape,” allowing businesses the opportunity to combine sustainability initiatives with efficiency efforts and customer demand.

“While the ‘Amazon Effect’ has led to heightened consumer expectations for quick delivery, there is a similar demand for eco-friendly products,” Howell says. “In fact, 90% of Gen X consumers say they’d be willing to pay more for sustainable items – compared to 34% just a couple of years ago.

“In today’s market, for businesses to prosper and expand they must discover novel approaches to meet rising demands for ESG standards, placing greater emphasis on responsible sourcing.”

Responsible sourcing within procurement

For businesses to build a responsible and resilient supply chain, leaders need to acknowledge that procurement is the first step. “The procurement team begins the sourcing process by evaluating potential goods and materials that would make up the products made and distributed in the supply chain,” says Etosha Thurman, Chief Marketing & Solutions Officer, of Intelligent Spend and Business Network at SAP.

“In their evaluation, they are considering the environmental, societal, and economic impact of sourcing the materials. For example, potential risks with energy efficiency, water and land usage, and hazardous materials.”

To ensure businesses adopt responsible sourcing, leadership needs to set out clear definitions which align with the ESG goals of the organisation. Procurement professionals must also be educated about the necessary steps to ensure the goods and services under consideration meet the criteria.

Technologies role in responsible sourcing

In today’s rapidly evolving business landscape, technology stands as a pivotal ally in driving sustainability across the source-to-pay (S2P) and procure-to-pay (P2P) processes. By seamlessly integrating innovative solutions, organisations can navigate strategic sourcing, procurement, and supplier relationships while adhering to responsible and ethical practices.

“Technology can help organisations follow sustainable practices at every stage of the S2P and P2P process,” Thurman says. “In strategic sourcing, the right solutions can help analyse current and future spending, find and source from suppliers, ensure compliance and reduce risk with sustainability in mind. SAP Ariba Sourcing is a good example of a solution that enables users to prioritise suppliers that align with ESG goals.”

During the P2P process, Thurman reminds organisations that it is important to use solutions that help guide business users to make risk-aware and sustainable purchases, ensuring contract compliance with sustainable procurement policies. “The guided buying capability in SAP Ariba Procurement solutions can help guide employees to purchase from sustainable suppliers,” she adds. “Technology can also be a valuable tool in nurturing relationships with sustainable suppliers. Taulia’s Sustainable Supplier Finance solution allows users to reward suppliers that share their ESG qualifications with early payment incentives.

What’s more, to build a sustainable and risk-resilient supply chain, businesses need to establish strong relationships with key suppliers, which must be diverse. The supply chain data then needs to be monitored and analysed in real time, and investment needs to be made in technologies that can enhance supply chain visibility and agility.

“Efficient, effective technology can help businesses acquire and manage the data and information they need to measure compliance, minimise risk and boost sustainability,” Howells says. “Businesses must examine their value chains comprehensively, from sourcing raw materials to understanding the end product’s lifecycle. By adopting technology-driven solutions like blockchain and IoT, companies can ensure that their sustainability efforts extend beyond the surface level to every aspect of their operations.”

What’s more, SAP works with its partners to provide efficient solutions to business operations, while recognising the importance of monitoring and measuring not only cost, speed, profitability and customer service, but increasingly, emissions, waste, inequality and other sustainability and risk KPIs across the supply chain. This can be accomplished by connecting every process, contextualising every decision and collaborating with partners without obstacles. However, there is no one-size-fits-all solution for supply chain complexities.

Howell explains: “Buyers on SAP Business Network can choose vendors based not only on price and availability but also on human rights records and third-party sustainability ratings. Suppliers share human rights questionnaires to their profiles on SAP Business Network, where buyers can access them. Buyers are automatically notified any time a supplier they are doing business with updates their questionnaire. This saves suppliers time and helps buyers easily prepare for due diligence processes.”

Final thoughts

Embracing responsible sourcing is paramount for businesses aiming to navigate the evolving landscape of sustainability, satisfy consumer demands and enhance their growth prospects. Through integrating technology, fostering diverse supplier relationships and monitoring supply chain data, organisations can achieve a holistic approach to ESG standards, ensuring lasting positive impacts on both their operations and the wider world.

In a rapidly changing business environment, responsible sourcing stands as a gateway to sustainable success. By aligning with ESG goals, leveraging technology-driven solutions, and nurturing supplier relationships, businesses can forge resilient supply chains that not only meet current demands but also pave the way for a more environmentally and socially conscious future.

M&S switches from plastic bags for life to paper options

Posted on by dishanth
M&S switches from plastic bags for life to paper options

The new bags have been rolled out to all M&S Stores with a food department across the UK. They are made using an FSC-certified paper and, according to M&S, are capable of carrying more than 15kg.

A natural resin is applied to the bags to enhance water resistance without rendering them hard-to-recycle.  Customers are being encouraged to use the bags multiple times before recycling at home and M&S claims this offers a convenience benefit, as plastic bags are not collected from homes and need to be taken to supermarkets with soft plastic collection points.

M&S’s director of corporate affairs Victoria McKenzie-Gould said “the vast majority” of customers –  more than 70% – already bring their own bags.

“But, on the odd occasion when we all need to reach for one more bag, we’re pleased to be offering a more sustainable option for customers,” she said.

A smaller and less robust paper bag will be added to M&S’s clothing and home departments. Like the food bag, it will be made using FSC-certified paper and be coated with a recyclable natural resin.

The switch means that M&S will need to find an alternative use for the soft plastics it collects in-store for recycling, which has, to date, been used to make bags for life. McKenzie-Gould said the intention is to incorporate this recycled content into bin bags.

M&S will continue to sell reusable tote bags in addition to the paper bags.

Push for paper packaging

Packaging company DS Smith revealed today that 80% of UK-based consumers would prefer to receive a product in paper or cardboard packaging than plastic packaging.

The firm polled 500 adults who shop online at least four times a year. One in five said they would be willing to pay more for a plastic-free option and one in four said they would not shop again with a brand they perceived to use too much unnecessary packaging.

“At a time when consumers are keeping an eye on their spending and competition for customers is fierce, brands risk losing business if their packaging fails to meet online shoppers’ increased sustainability standards,” said DS Smith’s e-commerce business unit lead for the UK, Anne Curtis.

Candy Bar Wrappers Go Plastic Free

Posted on by dishanth
Candy Bar Wrappers Go Plastic Free

For the first time since its launch in 1936, Nestlé is changing the packaging of their famous Mars candy bar wrapper for a more environmentally friendly alternative.

Traditionally, candy bar wrappers are made out of a combination of aluminum and plastic. These materials are difficult to recycle because of how hard it is to separate the two materials. Moreover, the plastic is not biodegradable and can take 10-20 years to decompose. This is at the risk of pieces remaining in the environment longer than that. At the end of their short life, candy bar wrappers will inevitably end up either in landfills or the environment.

New Jersey based TerraCycle has implemented a candy bar wrapper recycling program to address this problem, collecting used wrappers from individuals and institutions.

Candy bar wrappers are recycled at TerraCycle through a process called mechanical recycling. This process involves shredding the wrappers into small pieces, washing them to remove any contaminants, and then melting them down to create new plastic pellets. These pellets can then be used to make new products, such as benches, flower pots, or playground equipment.

TerraCycle offers a variety of recycling programs for candy bar wrappers. These programs are available to individuals, schools, businesses, and organizations. To participate in a program, the only cost is to purchase a collection kit from TerraCycle. The collection kit includes a shipping label and a prepaid shipping box.

Once you have purchased a collection kit, you can collect candy bar wrappers. You can collect wrappers from your own home, school, or workplace. When the collection kit is full, you can ship it back to TerraCycle for recycling.

Nestlé Steps Up

Nestlé is taking the problem of candy bar wrapper waste one step further by completely changing what their chocolates are packaged in. The company is piloting a program to wrap its Mars bars in recyclable paper.

The company also announced that it would be switching the plastic packaging on KitKat bars to 80% recycled plastic, allowing them to be recycled at supermarkets across the UK or put in household recycling bins in Ireland. This is an initiative that could save 1900 tonnes of CO2 annually.

In addition, the company is looking to explore new types of packaging. Nestle is investing hundreds of millions of pounds to redesign thousands of types of packaging. This investment will be put towards meeting its goal of reducing the use of virgin plastics by one-third by 2025. The company also plans for over 95% of its plastic packaging to be designed for recycling by 2025.

Nestlé’s Institute of Packaging Science has been working since 2019 to develop the next generation of packaging materials. In addition to recyclable packaging materials, they are looking at developing refillable or reusable packaging and how to incorporate compostable and biodegradable materials. The Institute’s strategy focuses on five pillars, all of which are linked to reducing waste:

  1. Reducing the use of plastic packaging material
  2. Scaling reusable and refillable systems
  3. Designing better packaging materials
  4. Supporting infrastructure to help make recycling easier
  5. Shaping new behaviours

Nestlé is a global food and beverage company that has been criticized for its water bottling operations. Critics argue that Nestle is extracting too much water from local communities, often with no meaningful compensation to local jurisdictions and areas already facing water shortages. Some have argued that the company doesn’t sell water; the company sells single-use bottles. Bottles that contribute to pollution and environmental damage.

The need for bottled water, is of course, a marketing ploy. Critics argue that Nestle’s marketing campaigns make bottled water seem like a healthier and more convenient alternative to tap water, even though there is no scientific evidence to support this claim.

The plastic-free Mars bars will be available at 500 Tesco stores in the UK for a limited time.

Milk & More to trial doorstep deliveries of refilled Coca-Cola

Posted on by dishanth
Milk & More to trial doorstep deliveries of refilled Coca-Cola

From next Monday (5 June), Milk & More customers in South London and some parts of the South will be able to buy one-litre bottles of Coke Zero which they will then be instructed to rinse and leave on their doorstep for collection.

The collected bottles will be sent off for washing and refilling; they can be refilled up to 20 times before they need to be recycled.

Milk & More already offers reusable glass bottles for several of its own-brand lines including milk, water, fruit juices and soft drinks. In total, it delivers 80 million refillable bottles each year already.

Milk & More’s chief executive Patrick Muller said: “Our customers want to be more sustainable, but they are busy people and need simple solutions to help them, so we are confident that they will welcome this trial as it offers them exactly the same service as they already have with Milk & More.”

The business is working with Europe’s largest Coca-Cola bottler, CCEP, on the new trial. It will run for a minimum of eight weeks and the hope is to reach 100,000 customers.

CCEP’s senior sustainability manager Jo Padwick said the trials will allow for the gathering of “valuable insights into how consumers respond to return-based trials in comparison to recycling”.

The Coca-Cola Company, globally, is notably aiming for 25% of its beverage sales to be housed in reusable or returnable packaging by 2030. It announced this target last year.

The Milk & More trials are being touted as the only way, at present, for UK-based customers to receive refillable Coca-Cola to their homes.

Pre-filled reusable Coca-Cola Company products have previously been offered via Tesco and Terracycle, under the Loop scheme. However, Tesco stopped offering Loop services last July.

Are fashion brands right to trial home-compostable bioplastic bags?

Posted on by dishanth
Are fashion brands right to trial home-compostable bioplastic bags?

Tuesday (13 December) saw the Amsterdam-based Fashion for Good initiative launching a new ‘Home-Compostable Polybag Project’. Under the project, retailers will trial alternatives to plastic polybags for six months, for applications like transporting products to stores, storing products in warehouses and completing online orders. They will seek to understand the transparency, durability and longevity of the innovative bags, plus how they are managed once they become waste.

Given that the fashion sector now uses more than 180 billion polybags each year, there is the potential for innovative solutions to displace a significant amount of single-use plastics that are hard to recycle.

Levi Strauss and C&A have signed on as the first brands to participate in the Project. They will be trialing compostable solutions from TIPA and Greenhope, which claim that their products will compost in either home composting environments or municipal facilities. Both firms have had the composability of their packaging verified by a third-party certification scheme. They provide packaging with 25-25% bio-based materials.

Fashion for Good clarified in a statement: “Composting can be tested in two environments, home environments and industrial environments. Home composability can happen in a backyard composting bin and at ambient temperatures, whereas industrial composability requires higher temperatures (50-60°C) and specific conditions at a large-scale facility.”

This Project is the latest in a string of efforts to tackle plastic polybags by Fashion for Good. The organization first stated plans to work on the topic in 2019, promising to look at a mix of solutions including recyclable options, compostable and reusable models. Last year, Fashion for Good published a whitepaper on scaling reusable models following trials with Zalando and Otto.

Commenting on this new phase, Levi Strauss’s chief sustainability officer called it an “exciting opportunity” that “not only moves Levi’s towards achieving [its] goal of eliminating single-use plastic in consumer-facing packaging by 2030, but also puts into practice the industry collaboration required to solve these ubiquitous challenges”.

C&A has a similar goal to replace at least half of single-use plastics in online shopping and the supply chain with more sustainable alternatives by 2028.

 

A truly sustainable alternative?

Fashion for Good has stated that “bio-based polymers have been found to have a lower carbon footprint when compared with fossil fuel-based polymers. The bio-based polymers are generated from biological feedstock, such as food crops, organic waste and wood pulp. The final compostable plastic blends are generally derived from a mix of bio-based materials and petroleum feedstocks.”

There are questions around whether the petroleum feedstock elements of compostable packaging have a lower carbon footprint, and about what happens to these kinds of materials when they are not processed in a municipal facility.

Packaging provider sourceful has this week published research revealing that the global compostable packaging market is likely to be three times larger in 2026 than it was in 2021. This means that infrastructure and collection schemes need to be scaled up – the UK, for example, has no public collection schemes for homes and, as such, only 3% of compostable are industrially composted.

Sourceful has emphasized that proper waste management is important because compostable ending up in landfill can have a significant climate impact. A study of the life-cycle emissions of 20 common packaging materials by Sourceful found that bags made with compostable mono-material films, when left to degrade in nature, generate 228 grams of CO2e each. A comparable virgin plastic bag generates 118 grams, the study found.

Looking at emissions across the lifecycle, the conclusion was that the compostable bag would generate 2.5 times more CO2e than the virgin plastic bag if both ended up in landfill.

Most packaging solutions in the compostable market cannot be managed at home at present. So, it bears noting that the solutions being used by Fashion for Good will have a different lifecycle carbon footprint due to their ability to be managed in homes.

Sustainability initiatives at Coca-Cola Europacific Partners

Posted on by dishanth
Sustainability initiatives at Coca-Cola Europacific Partners

Coca-Cola’s iconic bottles are internationally recognised, but Coca-Cola Europacific Partners aims to implement a more sustainable purpose for used bottles
For Coca-Cola Europacific Partners, Indonesia and Papua New Guinea, Lucia Karina is the Public Affairs, Communication and Sustainability Director. In her role, Karina is passionate about implementing sustainable strategies, utilising green energy and working together with stakeholders to support local communities.

“We embed our sustainability initiatives into our activities,” explains Karina. “Not only for the supply chain section, but also in the commercial side. So this forward strategy consists of water management, sustainable packaging, the climate, our society and the supply chain. We are also looking at how we can reduce our sugar content in our drinks.”

The company is also working to implement a reuse or recycle policy, to minimise the volume of Coca-Cola products going to landfill.

“We are removing unnecessary and hard-to-recycle packaging. We want to make sure that 100% of our packaging actually is recyclable.”

Coca-Cola has increased the recycled content in its packaging to reduce the use of new material, including plastic made from fossil-fuels. In Indonesia, the company joined with Dynapack Asia in a joint venture and built a PET recycling facility, with a capacity for 25,000 tonnes every year.

“In Indonesia we also built the social foundation Mahija Parahita Nusantara. This is a non-profit foundation and we are trying to work to improve the lives and welfare of the waste pickers that work in these communities. We want to ensure that we increase the quality of the collection for the feedstock of the Amandina Bumi Nusantara recycling PET.”

Mono-material packaging: A recycler’s wish

Posted on by dishanth
Mono-material packaging: A recycler’s wish

Recycling closes the loop for a circular economy, but the more complicated the packaging design, the lower the chance of it being recycled. Could mono-material packaging be the answer to this problem?

 

‘Circular economy’ has become the buzzword for businesses around the world, regardless of industry. Oftentimes, the phrase is merely used for marketing purposes, with little attention paid to its concepts and principles.

There are numerous players involved in the lifecycle of one product. From raw materials suppliers and logistics companies, to manufacturers, distributors, consumers, and disposal, it may not be sufficient when only one of the players upstream creates a ‘circular product’ without involving the other players downstream to ensure that the loop can truly be closed.

Over the centuries, the human-environment relationship has grown from a circular one to a linear one. In the past, what our ancestors used to take from nature was returned to nature at the end of its life.

 

No material is as difficult to differentiate as plastic.

 

From a material scientist’s perspective, civilisation developed along with newly synthesised materials that allowed technology to flourish—materials that nature is unable to assimilate in a short period of time. Nevertheless, learning to be better stewards of materials can drive our economy back to a circular one.

For the packaging industry, the answer may lie in mono-materials.

Packaging serves a necessary function—protecting or preserving the product it contains. The material chosen for the packaging has to satisfy this basic functionality. But as products get increasingly sophisticated, more functionalities of packaging are needed and a single material may not be able to satisfy all of the requirements.

Laminations, coatings and additives went into the material formulation to achieve the packaging solution. The need for labels to print the necessary product information and branding further complicated the design. This is how a simple packaging purely used to contain a product can become a concoction of differing materials.

Recycling cannot deal with mixed materials, even for plastics.

No material is as difficult to differentiate as plastic. A transparent plastic can be polyethylene terephthalate (PET), polyvinyl chloride (PVC) or even general-purpose polystyrene (PS).

But these plastics cannot be mechanically recycled together and have to be separated, if not the quality of the recycled PET (which has a higher recycled value) will be downgraded or even contaminated beyond reusability.

The process of mining iron comes from extracting iron ores since iron does not exist as a pure element on earth. This requires energy input to purify the ores to obtain pure iron before it can be further used in the manufacturing of products.

The reverse engineering of products (such as recycling) into individual materials follows the same process. Recycling could be an energy-intensive activity, but it helps to close the loop for a circular economy in packaging products.

However, the more complicated a packaging design, the more effort is needed.

Unfortunately, this segregation often comes from human intervention in developing countries before the actual recycling can take place. If packaging consists of only one material, these preliminary steps can be avoided. The pathway to recycling will also be shorter and more efficient.

For the multi-layered materials that cannot be separated, either simply because it is not economically viable or not intervenable manually, the easiest method would be to take the inseparable materials and downcycle them into a composite particle board.

The only way to know if this mixture of inseparable materials is durable or even toxic is through testing it, but the composite particle board is thereafter rendered non-recyclable.

Is it possible to standardise the transparent plastic type to use for takeaways?

When it comes to determining which plastics to use for packaging, retailers are simply spoiled for choice. But when it comes to service packaging (e.g. takeaway containers), do we really need to look beyond PET and PP?

In the resin code, 7 refers to ‘others’, yet this one number encompasses many different types of plastics, and even biodegradable plastics are currently listed under ‘7’.

To determine if the plastic is recyclable or not, a consumer must know what the resin code represents, and which types of plastic can be collected—which is dependent on the local recycling infrastructure. Such in-depth knowledge may fly over the face of most consumers.

Thus, standardising which mono-material to use for a certain type of packaging—especially those with low functionality such as single-use packaging—may be the key to ensure a truly circular economy.

Plastics have great flexibility when it comes to engineering the material into the required packaging properties. Yet it is the same flexibility that results in the proliferation of plastic types that goes beyond the 7 resin identification codes.

While certain industries like automobiles or electronics would benefit from advanced plastics, comparatively, packaging for everyday items does not require the same level of complexity.

With a thorough understanding of the recycling process and infrastructure, much can be done by the packaging design engineers to mindfully create packaging for ease of recycling.

And mono-material can be a great place to start.
