The groundbreaking study of the University of Greenwich and international collaborators proposes the best policy roadmap to revolutionize the EU’s plastic recycling capabilities, and uses cutting-edge system dynamics modeling to mitigate environmental and supply chain risks.
Amid growing global concerns about climate change and material scarcity, the European Union faces tough challenges. Although it produces more than 89 million tons of packaging waste each year, domestic recycling capacity is dramatically delayed, with over 10 million tons of disposal possible.
Decades relying on exporting waste to countries such as China, Malaysia and Vietnam collapsed in 2018 due to the imposition of a global waste import ban. This confusion revealed a serious vulnerability. The EU’s recycling infrastructure was not built for circulation. Built for outsourcing.
In a timely response, researchers at the University of Greenwich have worked with Greenovation Solutions (UK) and Westcon-Comstor (USA) to develop a dynamic model that predicts how different policy strategies will affect the EU’s ability to recycle packaging waste.
Their research, published in the Annals of Operations Research, employs systems dynamics simulations to rigorously test innovation-driven, subsidized, and market-oriented policy scenarios.
Innovation-focused policies lead to long-term benefits
Of the three policy types evaluated, innovation-focused policies (e.g. R&D grants, tax easing for green technology development) emerged as the most impactful over time.
These policies increase recycling productivity by promoting technical breakthroughs in material separation, sorting and remanufacturing. This model shows that such innovations will stimulate cost reductions, profitability improvements, capacity growth, and outperform all other policy types by 2040.
“It’s not just about supporting innovation, it’s not just about preventing the future, it’s about creating scalable domestic systems that eliminate the need to eliminate problems overseas,” explained Dr. Li Zhou, co-author of the University of Greenwich.
Subsidies provide immediate support but fade
Subsidies-focused policies – tax incentives for recyclers and public funding for collection systems – show short-term benefits, but the surveys have made them faster and higher. Without simultaneously stimulating and innovating the demand side, such subsidies risk becoming economically inefficient and unsustainable over time.
“Subsidies are necessary to support early stage ecosystems,” the author argued. “But they have to evolve in parallel with innovation and market maturity.”
Market-based mechanisms generate momentum
Interestingly, like the 2018 China Waste Prohibition, there are market-based policies that are most effective immediately after a shock, including minimum recycled content obligations, extended producer liability (EPR) rules, and public awareness campaigns. These policies rapidly stimulate demand for recycled materials and encourage manufacturers to increase recycled input usage.
The study recommends that the optimal policy mix, which allocates 84% of the resources to innovation-centric policies, 16% to market-based policies, and eliminates pure subsidies entirely.
Blueprints for circular resilience
This study marks the first time such a broad combination of EU recycling policies has been evaluated in a dynamic long-term simulation model. Using data from 28 EU countries, this model provides practical recommendations tailored to both the development and development of the recycled economy. It explains real-world economic signals, including inflation, profitability, and cost structure, while simulating disruptions such as global bans and price shocks.
For policymakers and fundraising institutions, its meaning is clear.
Investing in the green innovation ecosystem is paramount to achieving the EU’s 2030 goal of recycling 70% of packaging waste. Short-term market shocks should be eased through responsive market-based policies rather than temporary revisions. A customized policy mix based on local cost structure, waste volume and profitability metrics will give you the best results.
Drive circular transitions
With increasing scrutiny of environmental accountability, this study provides a science-supported policy guide for building resilient circular recycling systems in the EU. It resonates with the broader ambitions of European green trading and circular economy action plans, setting the stage for smarter regulatory frameworks and strategic innovation investments.
As the EU faces pressure to close the packaging waste loop, this study offers not only diagnostics, but dynamic prescriptions based on systems thinking, economic realism and technological foresight.
