The EU-funded ReBioCycle project demonstrated that PLA bioplastics can be recycled from mixed plastic waste and returned to virgin-quality material, marking a significant step toward circular packaging in Europe.
The consortium confirmed that PLA can be effectively sorted from mixed plastic waste streams using existing technologies before being chemically broken down into lactic acid and rebuilt into high-quality PLA with properties equivalent to virgin material.
“This is about making circularity real for industry,” says project coordinator Kevin O’Connor. “We’ve connected the full value chain in a way that supports both regulatory compliance and the transition away from fossil-based to bio-based materials.”
Key takeaways:
· The sorting process was carried out at pilot scale in an operational environment, showing that recycling of PLA is technically viable beyond the laboratory. This provides a practical pathway for integrating bioplastics into existing waste streams and recycling systems.
· The EU Packaging and Packaging Waste Regulation requires all packaging to be recyclable by 2030.
· The project confirmed that PLA can first be effectively sorted using existing technologies, achieving purity levels suitable for further processing. The recovered material was then successfully broken down into its core building block, lactic acid, using Torwash’s hydrolysis technology. In the final step, TotalEnergies Corbion
demonstrated that this recovered lactic acid can be repolymerized into recycled PLA with properties equivalent to virgin material.
· These achievements highlight that high-quality recycling of PLA from mixed waste is a working reality. The project effectively closes the loop, using real waste streams and industrially relevant processes to produce new bioplastic of high quality.
· Looking ahead, the consortium will focus on turning this technical success into market reality by developing and validating new applications using recycled PLA, while continuing to scale the process toward full industrial deployment.
