The EU-funded ReBioCycle project has 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.
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, at a time when industry faces increasing regulatory pressure under the EU Packaging and Packaging Waste Regulation, which requires all packaging to be recyclable by 2030.
Working with industrial partners including Torwash and TotalEnergies Corbion, 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 repolymerised into recycled PLA with properties equivalent to virgin material.
These achievements highlight that high-quality recycling of PLA from mixed waste is not a future ambition but a working reality. The project effectively closes the loop, using real waste streams and industrially relevant processes to produce new bioplastic of high quality.
Project coordinator Kevin O’Connor said the results demonstrate that circular solutions for bioplastics are already within reach. “This is about making circularity real for industry,” he said. “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 .”
As pressure mounts on the packaging sector to transition to more sustainable solutions, the project’s results provide timely evidence that biobased plastics can play a central role in a circular economy. The technologies developed can be integrated into existing infrastructure, lowering barriers to adoption while supporting broader European ambitions under the Green Deal and Bioeconomy Strategy.
“Demonstrating that recycling PLA from mixed waste collection to new high-quality PLA material is a reality, is a major step in fulfilling the ambitions of the PPWR in terms of packaging recyclability” says Maelenn Ravard, Regulatory and Sustainability manager at TotalEnergies Corbion. She adds “Achieving circularity is all about having a strong value chain and this is the strength of ReBioCycle consortium”.
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.
