Biotrend contributes to the transition to a circular bioeconomy and to the creation of sustainable plastics. In this week’s annual meeting of the RES-URBIS project www.resurbis.eu, waste-derived PHBV, a biodegradable biopolyester, comes to focus. Industrial food-processing waste was used by the team at the New University of Lisbon to select and grow mix microbial cultures able to accumulate PHBV. By using its novel aqueous-base method, Biotrend extracted and purified PHBV which could be effectively processed by extrusion at INRA/Montpellier to obtain a PHBV filament and by electrospinning at Bioinicia, further widening the range of applications.
