A The MIX-UP ambition to make the majority of the vast plastics biodegradable. B Overall schematic concept of the MIX-UP-project: mechanically pre-treated, unsorted plastic waste is exposed during Plastics Depolymerisation to heavily engineered, plastic type-specific enzyme blends. These enzymes have been produced preliminarily by defined mixed cultures during Enzyme production. Released metabolites, additives, plastic mono- and oligomers of various plastic types will be used as plastic derived feedstock for defined microbial communities (Mixed culture) to bio-convert them into biomass products (e.g. PHA), and secreted products released during upcycling processes, respectively. During Separation, downstream processing, removal of toxin (e.g. diamines) and product recovery will be tackled. Finally, recalcitrant residues will be subjected to Physicochemical treatments, thereby synthesising added-value products and closing MIX-UP cycle by re-entering into bioprocess steps
