Description
Seafood processing generates a huge amount of discards that can be used to recover valuable compounds. In this study, a biorefinery scheme is proposed to obtain calcium carbonate (liming agent), protein hydrolysates (biostimulant), biogas and a biochar-compost composite. Water would be also reused within the process, minimizing water footprint. From this scheme, 1 ton of raw waste could be valorized in 700 kg of a liming agent, 30 kg of biostimulant, 26 kg of biochar-compost composite and 1.2 Nm3 of methane.
