The new Horizon Europe-funded GRECO project provides innovative biobased, biodegradable and recyclable food packaging based on novel PLA copolymers, functional coatings, additives and green catalysts. GRECO aims to demonstrate the life cycle and techno-economic feasibility of greener and safer bioplastics value chains for the food packaging sector, based on a safe and sustainable-by-design strategy.
The GRECO project kick-off will take place in Valencia, at AIMPLAS on 16-17 June 2025. European Bioplastics and its members, including TotalEnergies Corbion, AIMPLAS, and INNOTECH COEXPAN-EMSUR, are among the 22 partners that have joined forces to develop and implement “Innovative biobased, biodegradable, recyclable, safe, and circular food packaging” under the lead of the Aristotle University of Thessaloniki (AUTH).
Dimitrios Bikiaris (AUTH), GRECO coordinator, indicates that “The GRECO project aligns with the new Packaging and Packaging Waste Regulation by developing biobased, biodegradable, and recyclable PLA copolymers for food packaging. Our goal is to create sustainable and circular solutions that reduce waste and environmental impact”.
At a demonstrative scale and in the real operational environment, GRECO will design, demonstrate and scale up food packaging materials (e.g., flexible and rigid applications for cheese, processed meat, fresh meat, berries, and nuts) that can meet diverse application needs, preventing moisture and aroma loss and increasing shelf life.
AIMPLAS is contributing to several tasks in GRECO. “We are particularly excited to implement reactive extrusion (REX) as a green chemistry technology for developing tailor-made and safe-and-sustainable-by design PLA-based copolymers for the food packaging sector, scaling them up to TRL 7”, said Belén Monje, leading researcher on Sustainable Chemistry. “Specifically, the contribution on the development of PLA- copolymers by reactive extrusion and on the production of additives by mechanochemistry is novel and groundbreaking and will make it possible to achieve more sustainable, biobased, recyclable and biodegradable PLA-compounds and coatings”.
Novel PLA copolymers will be developed and optimised with the modelling tools to drive the design of the polymers to improve the biodegradability, performance, production rates, yield, and quality in an iterative strategy.
“As part of GRECO, TotalEnergies Corbion is contributing to the development of new PLA copolymers that deliver improved packaging performance and functionality, while boosting recyclability and biodegradability”, said Jenifer Mitja from TotalEnergies Corbion. She added: “Significantly reducing carbon footprints, PLA’s versatility, biobased origin, and wide industrial availability make it a key enabler in addressing the performance and sustainability requirements set by the new Packaging and Packaging Waste Regulation”.^
GRECO will work on different end-of-life (EoL) scenarios, including testing the recyclability of the biobased polymers and materials with mechanical and chemical recycling (both in open and in closed-loop systems). Innovative recycling technologies will also be used on post-consumer plastic packaging approved for food contact and deliver decontaminated recycled-biobased polyesters.
At the same time, a biodegradability assessment will be performed for aerobic and anaerobic biodegradation. The biodegradability of the developed materials will be tested in marine, water, and soil environments. The materials will also be tested for industrial composting conditions and home composting. The certification bodies TÜV AUSTRIA Belgium and DIN CERTCO will benefit from the results of biodegradability testing in open environments and use the inputs to plan changes and revisions in their certification schemes.
The consortium will also collect and analyse qualitative and quantitative data on consumer needs and their perceptions to ascertain how GRECO products align with the perceptions of consumers and their related values, such as sustainability, usability, and accessibility.
