Unlocking New Value from Urban Biowaste: LCA of the VALUEWASTE Biobased Products

The VALUEWASTE project can offer a sustainable solution to transform biowaste into added-value bioproducts, such as proteins from microorganisms and insects biofertilizers. present study focused on the environmental impacts linked obtaining these which was performed by standardized Life Cycle Assessment (LCA) approach, using Environmental Footprint methodology evaluate midpoint impact categories considered. At same time, bioproducts coming were compared regular ones: other protein sources mineral fertilizers. results show that new are firm candidates reach market an point of view. Furthermore, their could be improved reducing energy use (the main contributor) within some categories, ecotoxicity global warming. In case biofertilizers, performance overall worse fertilizers, except for following categories: metal water scarcity. Nevertheless, biofertilizers come biowaste, extending circularity concept, local places, dependency actors. Hence, showed obtained real alternatives implement in circular economy. However, continuous improvement should performed.
