The UK Plastics Pact. has brought together all sorts of different people & organisations with one common mission: to change the way plastic is made and used for good. It’s the first ever pact like this in the world, and is being led by sustainability experts WRAP.
The pact was made possible by the Ellen MacArthur Foundation and their new Plastics Economy work, which has set out clear steps to get to a world where plastics are valued and never become waste. The ultimate dream.
By bringing together everyone who uses plastics across the whole chain with the government, and giving everyone bold and ambitious targets to hit, we’re working together towards keeping plastic in the recycling loop rather than letting it turn into litter which pollutes the environment. The pact covers the research and innovation of new packaging which will encourage businesses to rethink and redesign the stuff they put out into the world and proactively encourage people to re-use and recycle our packaging after they’ve finished with it.
4 key targets to hit by 2025:
1. put a stop to problematic or unnecessary single-use packaging through redesign and innovation
2. 100% of plastic packaging will be reusable, recyclable or compostable
3. 70% of plastic packaging will be recycled or composted
4. 30% will be the average recycled content for all plastic packaging
“Current culture is lead to believe that plastic is not biodegradable. This is incorrect. All plastic is organic in nature and has been proven to biodegrade by microorganisms by several differant groups, some of them being high school students in Canada and Ben Gurion University scientists in Israel. This information has paved the way for BioSphere to bring to market the following technology and become a rapidly growing worldwide used technology. The BioSphere technology allows microorganisms to produce CO2 and CH4, both of these are the result of the consumption of the plastic. When microorganisms consume anything aerobically or anaerobically these two gases are produced. Anaerobic biodegradation produces CH4 and Aerobic biodegradation produces CO2. The BioSphere technology allows the microbes to consume the plastic product in all active microbial environments.
The Science: BioSphere Plastic LLC technology is built on the fundamental properties of building polymers and depolymerization. In the molecular world, the small subunits that ultimately link together to form larger molecules are called monomers, which literally means “single unit” (mono = one). When a bunch of monomers join together into a much larger molecule, they form a polymer, meaning “many units” (poly = many). How does this “linking together” happen? There is a process by which this joining usually occurs, called dehydration synthesis. Two monomers line up next to each other, a hydrogen (H) from one monomer binds with a hydroxyl group (OH) from another monomer, and voilà! A water molecule is born: H+ + OH- = H2O. During dehydration synthesis, two subunits, or monomers, bind to each other where they were once bound to their respective hydrogen (–H) or hydroxyl (–OH) groups. This blissful union is presided over by an enzyme that is mainly there to help speed things along. The name of the process is dehydration synthesis because monomers are literally coming together and synthesizing a polymer by dehydrating, or removing a water molecule. This is how a polymer is formed. How a polymer is hydrolyzed is the basis of our technology. This is done by the addition of water between the bonds. Now the question that people wonder is how we do just that. Anytime you allow water to attack the bonds between polymers this allows for hydrolyzing of the bonds which in turn lowers the molecular weight of the product. The addition of BioSphere additive introductes key elements into the polymer structure which allow hydrolyzation of the polymer. Microbes produce enzymes, these enzymes are part of the organic cycle which produce reactions. Reactions by enzymes which are produced only by microorganisms create catalysts which are formed by gram-negative and grampositive bacteria. The catalysts accelerate metabolic reactions. The metabolic reaction we use (even though there are multiple metabolic pathways in this reaction) is the carbohydrate metabolism. We boost the ATP to carry more energy back to the pyruvic acid (Anaerobic) or the Acetyl CoA(Aerobic) cycles. This in turn creates proteins or lipids from the Pyruvic Acid cycle (Anaerobic) and acetyl CoA cycle(Aerobic). This process created by microorganisms does not occur on the shelf, nor does it occur when water is in contact with the plastic. This reaction of microorganisms only occurs when the product is placed in an active microbial environment. BioSphere additive attracts over 600 differant types of microbes to consume the polymer. The enzymes that the microbes produce react with the BioSphere addtiive creating a catalyst that breaks down the molecular weight of the polymer making it easier for microorganisms to consume the plastic. This is called biodegradation.”
“Recent success in reducing carrier bag (PE) and drinks bottles (PET) waste in Europe suggests lifestyle adjustments are possible, but plastic is ingrained in modern society and a future free from plastic seems unlikely. Complete alteration of human behaviour is difficult to attain, as indicated by the fact that only 9% of plastic waste is recycled3. Therefore in addition to these three solutions to the plastic waste problem (reducing, reusing and recycling), we need a fundamental change in order to make a noticeable impact on the plastic waste seeping into our environment. A new plastic future in which biodegradable polymers replace conventional plastics could be the answer.” source: https://www.nature.com/articles/s41467-018-04565-2
“Some bacteria think plastic is fantastic Bacteria isolated from outside a bottle-recycling facility can break down and metabolize plastic. The proliferation of plastics in consumer products, from bottles to clothing, has resulted in the release of countless tons of plastics into the environment. Yoshida et al. show how the biodegradation of plastics by specialized bacteria could be a viable bioremediation strategy (see the Perspective by Bornscheuer). The new species. Ideonella sakaiensis, breaks down the plastic by using two enzymes to hydrolyze PET and a primary reaction intermediate, eventually yielding basic building blocks for growth.”

“ReverteTM is an oxo-biodegradable additive which is added directly into the film manufacturing process to standard PE, PP & PET to impart this property, with almost no physical impact on the processing of the polymer.”
“These polymers undergo controlled degradation through the incorporation of a ‘prodegradant’ additive (an additive that can trigger and accelerate the degradation process). These polymers undergo accelerated oxidative defined degradation initiated by natural daylight, heat and/or mechanical stress, and embrittle in the environment and erode under the influence of weathering.Reverte™ produces a plastic product with equivalent performance characteristics than the present non-degradables, is cost competitive and results in a product will totally and harmlessly disintegrate in multiple environments, commencing at a predetermined time.”
Food companies trying to reduce their consumption of plastic have a big problem — it’s hard to find suitable recycled material. Nestlé says it’s willing to spend more than $2 billion to try and fix that.
The world’s biggest foodcompany said in a statement Thursday that it would cut costs in other parts of its business to free up more than 1.5 billion Swiss francs ($1.6 billion) to buy 2 million metric tons of recycled plastic between now and 2025.
Nestlé said it would be paying above the market rate for the recycled material, part of its strategy to alleviate a shortage of used plastics suitable for food packaging by luring new suppliers into the business. Doing so shouldhelp the company meet its goal of reducing its use of virgin plastics by a third by 2025.
“Making recycled plastics safe for food is an enormous challenge for our industry,” Mark Schneider, chief executive of Nestlé, said in a statement.
“That is why in addition to minimizing plastics use and collecting waste, we want to close the loop and make more plastics infinitely recyclable,” he added
“The vision of INDIANES is that banana fiber is the solution to the environmental crisis caused by the textile and fashion industry. Banana fiber was used for centuries by Colombian communities and does not require any water or extension of land for cultivation, since it is obtained from the residues of banana agriculture.”
“Mattel announced its goal to achieve 100% recycled, recyclable or bio-based plastics materials in both its products and packaging by 2030.
This new goal expands the Company’s Environmental Sustainable Sourcing Principles that were announced in 2011. The Company now sources 93% of the paper and wood fiber used in its packaging and products from recycled or Forest Stewardship Council (FSC) content, surpassing its 2018 goal of 90%. In addition, the Company has adopted the How2Recycle label, a standardized labeling system that clearly communicates recycling instructions to the public.”
“As soon as we’d received the Generation 1 shoes, we were able to start Phase 2. We collected the shoes, recycled them, kept them in our supply chain and ultimately remade the recycled material into new running shoe components. The material is melted and developed into new pellets, which are heated to form new components including the eyelets and outsole. Virgin TPU material is used to create the remaining components of the midsole and upper. The remade and new materials are fused together to create Generation 2: a running shoe in a blue colourway, that remains one material and is still 100% recyclable for the next generation. So, this is where we are today: launching the next generation of FUTURECRAFT.LOOP and one step closer to a consumer reality – all in the space of just eight months. A first for adidas”.
This Co.Project brought together a range of CE100 members to explore case studies and examples of how retailers can engage with their customers post point of sale to unlock economic opportunities. Cranfield University, Arizona State University and PA Consulting Group surveyed 250 consumers in the US, UK, France and Spain on post-sale behaviours – with a survey response rate of 72 per cent. The conclusions in this report reflect the analysis of the survey results, company case stories and the authors’ experience across a range of markets and geographies.
CE100 Co.Project partners that contributed to the wider report include Stuffstr, eBay, Kingfisher, Philips, Waste and Resources Action Programme (WRAP) and the Ellen MacArthur Foundation. This report was co-authored by PA, Walmart and the Ellen MacArthur Foundation.
“In a new plastics economy, plastics will never become waste or enter the ocean in the first place,” said Ellen MacArthur, an ex-sailor who began her eponymous foundation in 2009.
“These winning innovations show what’s possible when the principles of a circular economy are embraced. Clean-ups continue to play an important role in dealing with the consequences of the waste plastic crisis, but we know we must do more. We urgently need solutions that address the root causes of the problem, not just the symptoms.
“To get there will require new levels of commitment and collaboration from industry, governments, designers and startups,” she continued. “I hope these innovations will inspire even more progress, helping to build a system in which all plastic materials are reused, recycled or safely composted.”
This article by Anne Marie Mohan, senior editor at packworld.com shows every advancement made on biopolymers applied on the packaging industry.
The industrial sector is at its beginnings but huge players such as PepsiCo are partnering with companies active on developing new bopolymers, which are seen as a natural evolution of the actual plastic industry.
New kinds of manufacturing byproducts are being used to produce biopolymers.
Mixed with traditional plastics, these materials not only reduce drastically the carbon footprint of the products on which are applied, but can offer superior properties.
A new generation of sustainably minded designers is pioneering ways of using recycled plastic as a raw material, as concern over pollution increases.
For decades, “virgin plastic” has been used to produce everything from food packaging to furniture. But, as the environmental impact of this material becomes more apparent, an increasing number of designers are exploring alternatives. https://www.dezeen.com/2018/02/02/recycled-plastic-only-choice-say-designers/
“We’re living in a culture where everything we consume and interact with can be tailored to our personal needs, and this expectation for the customisation of our lives and surroundings has – in recent years – found its way to our possessions. But what does the rise of personalisation mean for design? How does it change our products and the design process behind them? Last night It’s Nice That and IKEA hosted The Future of Design: How Personalisation is on the rise for the mass audience, a panel discussion exploring the topic, featuring four experts in the field”.
Plastic is an important and ubiquitous material in our economy and daily lives. It has multiple functions that help tackle a number of the challenges facing our society. Light and innovative materials in cars or planes save fuel and cut CO2 emissions. High-performance insulation materials help us save on energy bills. In packaging, plastics help ensure food safety and reduce food waste. Combined with 3D printing, bio-compatible plastic materials can save human lives by enabling medical innovation.
However, too often the way plastics are currently produced, used and discarded fails to capture the economic benefits of a more ‘circular’ approach and harms the environment. There is an urgent need to tackle the environmental problems that today cast a long shadow over the production, use and consumption of plastics. The million tonnes of plastic litter that end up in the oceans every year are one of their most visible and alarming signs of these problems, causing growing public concern.
Rethinking and improving the functioning of such a complex value chain requires efforts and greater cooperation by all its key players, from plastics producers to recyclers, retailers and consumers. It also calls for innovation and a shared vision to drive investment in the right direction. The plastics industry is very important to the European economy, and increasing its sustainability can bring new opportunities for innovation, competitiveness and job creation, in line with the objectives pursued by the renewed EU Industrial Policy Strategy. 1
In December 2015, the Commission adopted an EU Action Plan for a circular economy. 2 There, it identified plastics as a key priority and committed itself to ‘prepare a strategy addressing the challenges posed by plastics throughout the value chain and taking into account their entire life-cycle’. In 2017, the Commission confirmed it would focus on plastics production and use and work towards the goal of ensuring that all plastic packaging is recyclable by 2030.”
‘A vision for Europe’s new plastics economy’
A smart, innovative and sustainable plastics industry, where design and production fully respects the needs of reuse, repair, and recycling, brings growth and jobs to Europe and helps cut EU’s greenhouse gas emissions and dependence on imported fossil fuels.
−Plastics and products containing plastics are designed to allow for greater durability, reuse and high-quality recycling. By 2030, all plastics packaging placed on the EU market is either reusable or can be recycled in a cost-effective manner.
−Changes in production and design enable higher plastics recycling rates for all key applications. By 2030, more than half of plastics waste generated in Europe is recycled. Separate collection of plastics waste reaches very high levels. Recycling of plastics packaging waste achieves levels comparable with those of other packaging materials.
−EU plastics recycling capacity is significantly extended and modernised. By 2030, sorting and recycling capacity has increased fourfold since 2015, leading to the creation of 200 000 new jobs, spread all across Europe. 19
−Thanks to improved separate collection and investment in innovation, skills and capacity upscaling, export of poorly sorted plastics waste has been phased out. Recycled plastics have become an increasingly valuable feedstock for industries, both at home and abroad.
−The plastics value chain is far more integrated, and the chemical industry works closely with plastics recyclers to help them find wider and higher value applications for their output. Substances hampering recycling processes have been replaced or phased out.
−The market for recycled and innovative plastics is successfully established, with clear growth perspectives as more products incorporate some recycled content. Demand for recycled plastics in Europe has grown four-fold, providing a stable flow of revenues for the recycling sector and job security for its growing workforce.
−More plastic recycling helps reduce Europe’s dependence on imported fossil fuel and cut CO2 emissions, in line with commitments under the Paris Agreement.
−Innovative materials and alternative feedstocks for plastic production are developed and used where evidence clearly shows that they are more sustainable compared to the non-renewable alternatives. This supports efforts on decarbonisation and creating additional opportunities for growth.
−Europe confirms its leadership in sorting and recycling equipment and technologies. Exports rise in lockstep with global demand for more sustainable ways of processing end-of-life plastics.
In Europe, citizens, government and industry support more sustainable and safer consumption and production patterns for plastics. This provides a fertile ground for social innovation and entrepreneurship, creating a wealth of opportunities for all Europeans.
−Plastic waste generation is decoupled from growth. Citizens are aware of the need to avoid waste, and make choices accordingly. Consumers, as key players, are incentivised, made aware of key benefits and thus enabled to contribute actively to the transition. Better design, new business models and innovative products emerge that offer more sustainable consumption patterns.
−Many entrepreneurs see the need for more resolute action on plastics waste prevention as a business opportunity. Increasingly, new companies emerge that provide circular solutions, such as reverse logistics for packaging or alternatives to disposable plastics, and they benefit from the development of digitisation.
−The leakage of plastics into the environment decreases drastically. Effective waste collection systems, combined with a drop in waste generation and with increased consumer awareness, avoid litter and ensure that waste is handled appropriately. Marine litter from sea-based sources such as ships, fishing and aquaculture are significantly reduced. Cleaner beaches and seas foster activities such as tourism and fisheries, and preserve fragile ecosystems. All major European cities are much cleaner.
−Innovative solutions are developed to prevent microplastics from reaching the seas. Their origin, routes of travel, and effects on human health are better understood, and industry and public authorities are working together to prevent them from ending up in our oceans and our air, drinking water or on our plates.
−The EU is taking a leading role in a global dynamic, with countries engaging and cooperating to halt the flow of plastics into the oceans and taking remedial action against plastics waste already accumulated. Best practices are disseminated widely, scientific knowledge improves, citizens mobilise, and innovators and scientists develop solutions that can be applied worldwide.
Improving the economics and quality of plastics recycling
Stepping up the recycling of plastics can bring significant environmental and economic benefits. Higher levels of plastic recycling, comparable with those of other materials, will only be achieved by improving the way plastics and plastics articles are produced and designed. It will also require increased cooperation across the value chain: from industry, plastics manufacturers and converters to public and private waste management companies. Specifically, key players should work together to:
−improve design and support innovation to make plastics and plastic products easier to recycle;
−expand and improve the separate collection of plastic waste, to ensure quality inputs to the recycling industry;
−expand and modernise the EU’s sorting and recycling capacity;
−create viable markets for recycled and renewable plastics.
Using a plant-derived solvent called GVL (gamma-Valerolactone), University of Wisconsin-Madison Professor of Chemical and Biological Engineering James Dumesic and his team have developed an economical and high-yielding way of producing furandicarboxylic acid, or FDCA. One of 12 chemicals the U.S. Department of Energy calls critical to forging a “green” chemical industry, FDCA is a necessary precursor to a renewable plastic called PEF (or polyethylene furanoate) as well as to a number of polyesters and polyurethanes.
“Until now, FDCA has had a very low solubility in practically any solvent you make it in,” says Ali Hussain Motagamwala, a UW-Madison graduate student in chemical and biological engineering and co-author of the study. “You have to use a lot of solvent to get a small amount of FDCA, and you end up with high separation costs and undesirable waste products.”
Motagamwala and colleagues’ new process begins with fructose, which they convert in a two-step process to FDCA in a solvent system composed of one part GVL and one part water. The end result is a high yield of FDCA that easily separates from the solvent as a white powder upon cooling.
The team’s techno-economic analysis suggests that the process could currently produce FDCA at a minimum selling price of $1,490 per ton. With improvements, including lowering the cost of feedstock and reducing the reaction time, the price could reach $1,310 per ton, which would make their FDCA cost-competitive with some fossil fuel-derived plastic precursors.
“We think this is the streamlined and inexpensive approach to making FDCA that many people in the plastics industry have been waiting for,” says Dumesic. “Our hope is that this research opens the door even further to cost-competitive renewable plastics.”
