Session Highlights on Plastics and the Bioeconomy
The seminar commenced with Lorette Du Preez from EUROPEAN BIOPLASTICS discussing how legislation like the Global Plastics Treaty can enhance bioplastics’ role in achieving a circular economy. Du Preez flagged challenges such as high costs and lack of demand, urging stronger legislative support. Filippo Giancarlo Martinelli from MAGFI presented recycling technologies, notably the ReBioCycle project, which aims to facilitate bioplastics’ integration into the circular economy. Jesús Agüero of BIOVAL noted that biotechnology has been recognized as a strategic sector in Valencia’s reindustrialization strategy.
Bioplastics Production from Waste
The second session explored bioplastics manufactured from waste, featuring Caterina Coll from PERSEO BIOTECHNOLOGY. She outlined how organic waste, particularly from urban and agri-food sources, is transformed into valuable products like bioethanol and biofertilizers. Pablo Ferrero from AIMPLAS discussed the environmental benefits of biopolymers in reducing pollution and fossil fuel dependence. Innovations in waste processing were highlighted by Rosa Puig of NOVAMONT, while Jenifer Mitjà from TotalEnergies Corbion focused on end-of-life solutions for polylactic acid (PLA).
Post-Production Techniques
Bruno Ferreira of BIOTREND emphasized various production methods for polyhydroxyalkanoates (PHAs). José María Guijarro from SAV elaborated on leveraging biotechnology for managing residues like rice straw, while Vincent Gavroy of APPLEXION introduced purification technologies to enhance fermentation for bio-based products.
Advancements in Microbial Recycling
Laura de Eugenio from CSIC highlighted innovations in enzymatic recycling, with Kristie Tanner from DARWIN BIOPROSPECTING discussing the commercialization of microbial applications. Christian Sonnendecker from the University of Leipzig shared insights on advancing enzymatic recycling processes for plastics such as PET and PBS.
Biodegradability and Compostability Research
On day two, Francesco Colizzi from IQAC offered strategies to enhance polymer biodegradation via enzyme modification. Presentations by Jing Liu and Elton Melo introduced new methods for testing biodegradability, while Gemma Buron’s work on polyethylene degradation stood out. Elena Domínguez emphasized the agricultural benefits of biotech-derived bioplastics aligned with sustainability goals.
Techno-Economic Analysis and Future Projects
The final session included Apostolis Koutinas presenting research on bioplastic degradation in packaging, followed by Kealie Vogel’s life cycle analysis of wood-derived biopolymers. A roundtable discussion centered around the RED MARFIL project, showcasing efforts to develop new bioplastics from biomass waste for valuable applications in agriculture and transport.
The seminar was supported by multiple organizations, underscoring its collaborative nature and shared commitment to advancing bioplastics and sustainability.
