LIFE BioTHOP project addresses the challenge of developing a new cross-sector value chain to produce biodegradable, compostable and recyclable products with enhanced environmental sustainability and mechanical functionality. These new bioplastic products will compete with the fossil-based counterparts in terms of price by utilising low cost waste-derived hop fillers; in mechanical functionality, through the use of a composite approach; and in sustainability terms, through the vertical energy integration of mass site production pathways.
