Finally, analysing and supporting the social acceptance of circular bio-based products has been launched, whilst the project is being disseminated amongst stakeholders with the goal to achieve engagement and knowledge sharing.

The ambition of PROMOFER project is linked (i) to the use of specific biobased wastes from different industries, generated in significant amounts in Europe and showing specific overcomes to be valorised into high-added value products and (ii) to improve fermentative processes to produce bioplastics (PHBV and PU), whose yield are often inefficient to compete with chemical synthesis processes. On the one hand, agro-industrial wastes (low value starches, whey permeate, industrial wastewater) will be used to produce PHBV a biodegradable and biobased bioplastic. On the other hand, lignocellulosic biomass (rice straw, wheat straw and prune waste) will be used to produce 2,3-BDO a chain extender in thermoplastic polyurethanes.

PROMOFER project will establish different strategies for the improvement of the different bottlenecks present at industrial level in the production processes of two highly valuable compounds for the biobased market such as PHBV and 2,3-BDO. PROMOFER will contribute to significant knowledge advancements of the state-of-the-art in biobased waste treatments, improvements of strain capacities, uses of biocatalysts, process designs and downstream processes.

PROMOFER is coordinated by Aimplas and the Consortium counts 13 partners from 7 European Countries. The project will run for 48 months, until June 2028.
