Marine plastic recycling presents significant technical difficulties because recovered materials often contain mixed polymers, sand, salt and other contaminants.

Summary

EU-Funded Research Achieves Breakthrough in Marine Plastic Sorting
Researchers supported by the European Union have developed an advanced technology capable of separating contaminated marine plastic waste with more than 95% purity. The breakthrough, achieved through the CUPOLA project, could improve the quality and commercial potential of plastics recovered from oceans.
Recovered Plastics Could Become Valuable Industrial Products
The technology prepares marine plastic waste for thermochemical processing methods such as pyrolysis and gasification. These processes can convert sorted materials into industrial chemicals, alternative fuels, functional carbon materials, refinery-compatible hydrocarbons and asphalt.
Pilot-Scale Facility Planned to Test Commercial Potential
The research team has incorporated process modelling and economic assessments to evaluate the commercial feasibility of the technology. Establishing a pilot-scale facility is the next priority, allowing researchers to assess its performance under real operating conditions and determine its potential for wider industrial deployment.

SEATTLE (Scrap Monster): Researchers supported by the European Union have developed an innovative technology capable of separating contaminated marine plastic waste with more than 95% purity. The development opens new possibilities for converting ocean pollution into valuable industrial materials.

The breakthrough emerged from the CUPOLA project, funded through the Marie Skłodowska-Curie Actions (MSCA) Staff Exchanges programme. The project forms part of broader EU efforts to address plastic pollution. Since 2014, MSCA has supported 824 ocean- and water-related projects through €441 million in funding.

New Study Sets Numerical Target for Efforts to Combat Marine Plastic Pollution

Marine plastic recycling presents significant technical difficulties because recovered materials often contain mixed polymers, sand, salt and other contaminants. The CUPOLA team addressed this challenge by developing an advanced sorting process designed to prepare recovered plastics for high-quality recycling.

The research involves using established thermochemical conversion methods, particularly pyrolysis and gasification, to transform the sorted waste into useful products such as industrial chemicals, alternative fuels, functional carbon materials, refinery-compatible hydrocarbons and asphalt. The research also incorporated process modelling and economic assessments to examine the commercial feasibility of the proposed technologies.

The next priority is to establish a pilot-scale facility to test the technology under actual operating conditions.
