A legacy of scientific advances and policy actions on plastic pollution – the LABPLAS project reaches the end

After two productive days in the final General Assembly in Vigo, Spain, the LabPlas H2020 Project has come to an end. Four years of intensive research into the sources, transport, and impact of plastic pollution, made LABPLAS reach significant advances on several fronts. The project tackled the full land-to-sea continuum, aiming to equip European authorities with the robust scientific evidence needed to inform and support effective plastic governance policies. LABPLAS harmonized sampling tools across environments, expanding the monitorable plastic size fraction down to 10 µm, and developed novel analytical techniques capable of detecting and identifying nanoplastics as small as 30 nm. It also integrated advanced toxicity testing schemes to assess plastic impacts across food webs and created a suite of environmental models to fill spatial and temporal gaps not covered by field measurements. LABPLAS also developed biodegradation test methods tailored to freshwater, marine, and soil environments, along with a comprehensive Life Cycle Assessment (LCA) framework for evaluating biodegradable plastics.  At the macro level, the AIR Centre made notable contributions with the development of the open-source POS2IDON tool (Pipeline for ocean feature detection with Sentinel 2) to detect suspected areas of floating plastics accumulations in the ocean using Sentinel-2 satellite imagery and machine learning models. While the absence of large plastic patches prevented full validation in LABPLAS case study areas, the developed platform (POS2IDON) was applied in locations where large aggregations of plastics was foreseen or known, such as the highly-polluted Honduras Gulf, or the coasts of Mexico and Southwestern Europe following major disasters or events (see below).

As part of this effort, AIR Centre enabled a series of High-Level Dialogues on Plastics Governance, engaging policymakers, scientists, and industry leaders to address the growing challenge of plastic pollution. Outcomes from these discussions led to the creation of several Policy Briefs. 📘 Learn more in LABPLAS policy briefs focusing on:

• Tyre particle emissions
• Biodegradable plastics and their lifecycle impacts
• Plastic additives and toxicity
• Analytical methods for SMNPs

In addition to the policy briefs on specific topics, the AIR Centre also contributed with general policy recommendations on the governance of plastics based on the outcomes of the high-level events organised in the context of LABPLAS. Read the full report Overall, the LABPLAS project has taken remarkable strides in understanding, measuring, modelling, and addressing plastic pollution across environments and scales. Its multidisciplinary research has produced a rich legacy of tools, data, methods, and policy-relevant insights that will continue to guide future research and support the development of effective plastic governance.  The project’s final outcomes, including key scientific results and policy recommendations, are consolidated in the LABPLAS Legacy Document, available at: 🔗 https://labplas.eu/legacy-document/
