Investments in physical infrastructure and technology upgrades are needed to radically improve recycling economics, quality, and uptake. In 2016, the global share of mismanaged plastics was around 41%, and has been projected to increase to 56% in 2040, contributing to almost tripling the annual volume of plastic entering the ocean. Part of this has to do with the fact that a substantial share of global plastic waste today is still left uncollected, while a share of collected waste ends up directly being dumped into the environment. To help increase well-managed collection rates, investments in rural areas will particularly be needed since they represent 45% of uncollected waste and account for a similar share of plastic leakage into the ocean. For middle-/low-income countries, where funding is less available but whose informal sector plays an essential role in the collection of 59% of all plastic recycled globally, investing in the formalisation of the sector could increase the value of after-use plastic packaging and reduce the likelihood for material leakage.
When it comes to sorting and recycling processes, only 35–40% of the virgin material value of plastics collected for recycling is currently retained for a next use cycle (due to significant losses during processing), indicating the need to complement efforts to increase the collection rates with actions to drastically improve recycling yield, quality, and economics. This will require directing investments towards the scale-up of sorting and recycling processes, while making use of the latest technology upgrades—such as advances in process control, chemical marking technologies, and automation. However, the ability to create high-purity after-use streams at competitive prices will largely depend on packaging and material design; an essential upstream measure that can help unlock the full potential of recycling and reprocessing efforts. The Ellen MacArthur Foundation’s 2017 report, The new plastics economy: catalysing action, has estimated that by leveraging such measures, together with packaging designed for recirculation, recycling economics could be improved by around USD 190-290 per tonne collected, or USD 2–3 billion annually across OECD countries. To tap into such benefits, investments of at least USD 150 billion will be required in collection and reprocessing over the next five years alone to ensure that the plastics we do need can be circulated. This has led many, such as the Polyolefin Circular Economy Platform (PCEP), to call for investment decisions—taken as part of recovery packages—to contribute to shaping forward-looking infrastructure that will accelerate the transition to a circular economy. However, without significant action on elimination and redesign these costs would be significantly higher.
Packaging design in particular has a direct and significant impact on the economics of recycling. Without fundamental redesign and innovation, about 30% of plastic packaging will never be reused or recycled, and non-recyclables entering the recycling streams result in additional net costs. As an example, opaque PET bottles, that are difficult to recycle, add an estimated USD 1-2 million a year in avoidable costs to the French recycling system.
Policymakers are increasingly turning their attention towards policies that improve recycling economics and support the creation of markets for recycled plastics. In the EU, for example, a new tax on non-recyclable plastic packaging waste (EUR 0.80 per kilogramme or EUR 800 per tonne) will be introduced as of 1st January 2021, with the ambition to increase recycling rates. However, the effectiveness of the measure in tackling the systemic issue is still being debated. Other actions taken prior to the pandemic include the EU Strategy for Plastics in the Circular Economy with the ambition to increase sorting and recycling capacity fourfold by 2030. The new EU Circular Economy Action Plan contributes to this by mobilising policies that: improve product design towards reuse and recyclability, reduce complexity of packaging materials, boost the recycled content of products, improve separate collection of plastic waste, and reduce single-use plastics where necessary.
Investments in recycling infrastructure can also offer opportunities to address climate change and create additional jobs. A study by Material Economics showed that scaling high-quality recycling processes within Europe could supply up to 60–70% of the material input needed for plastics production, approaching the recycling levels for aluminium today. With recycling saving around 90% of the CO2 emissions arising from new production, this can have a significant impact. Not only do these technologies help us to meet our climate targets, but they can also create jobs in higher income economies. According to some studies, on a per-tonne basis, the processing of recyclables alone can sustain about 20 times more jobs than landfill, and plastic manufacturers making use of recycled materials, about 100 times more jobs than landfill.
For the world’s emerging and lower income cities, investments in after-use infrastructure offer much needed economic and societal opportunities. Around the world, an estimated 15–20 million waste pickers earn a living from the informal collection, sorting, and recycling of discarded items. Worldwide, they may even be responsible for collecting more plastic for recycling than the formal sector, accounting for 15–20% of collection globally. For two-thirds of waste pickers, these earnings are the main source of household income, with more than three-quarters of them having formal businesses as their main buyers. However, the pandemic has made informal communities particularly vulnerable, facing unprecedented threats to their health, safety, and livelihoods. Their health has been jeopardised, due to limited access to healthcare, hygienic necessities, and protective equipment, and their jobs threatened, due to temporary shutdown of recycling centres. As such, investing in and formalising this sector could offer huge opportunities to keep materials in circulation, while also improving sanitary conditions and alleviating poverty.
When it comes to tackling plastic pollution, however, focusing on collection, sorting, and recycling alone will not be enough. According to the July 2020 report developed by The Pew Charitable Trusts and SYSTEMIQ called Breaking the Plastic Wave: A Comprehensive Assessment of Pathways Towards Stopping Ocean Plastic Pollution, applying a strategy that focuses solely on recycling—including an ambitious design for recycling coupled with a scale-up of collection, sorting, and recycling infrastructure—would still result in “18 million metric tons of plastic flowing into the ocean each year by 2040”. The latter would cost governments USD 250 billion more than if an integrated system-level approach was taken (see paragraph below), between 2021 and 2040. Therefore, any solution based solely on waste management and recycling is highly unlikely to succeed in stopping plastic pollution—as it will neither be technically nor financially feasible. A comprehensive circular economy for plastic is needed, in which it never becomes waste or pollution.
An integrated approach is needed that deploys both upstream and downstream solutions to effectively tackle plastic pollution. This includes the global implementation of multiple synergistic system interventions by industry and government such as the elimination of problematic and unnecessary plastic packaging, switching from single-use to reuse models, scaling waste collection, sorting and recycling, and substitution to other materials where relevant. Compared with business-as-usual, such a comprehensive circular economy approach has the potential to reduce the annual volume of plastics entering our oceans by over 80%, generate savings of USD 200 billion per year, reduce greenhouse gas emissions by 25%, and create 700,000 net additional jobs by 2040. To catalyse change towards such an integrated approach, collaboration across sectors and regions are needed that is driven by a shared sense of direction. It is for this reason that the New Plastics Economy initiative has spent the last four years rallying businesses and governments behind its common vision of a circular economy for plastic. Today, this vision unites more than 850 organisations across the plastics value chain, public and private sectors through the New Plastics Economy Global Commitment and Plastics Pact network. These initiatives drive collective action to eliminate the plastic we don't need, to innovate so that all plastic we do need is reusable, recyclable, or compostable, and to circulate all the plastic we use, keeping it in the economy and out of the environment.
