Resource-smart upcycling fish processing side streams as part of a circular economy (UP-SIDE)
Seafood production generates up to 70% side streams, which are mainly used for feed or biogas today. The pH shift process is a unique tool to produce high-quality food proteins and oil from these side streams instead; enabling shorter and less energy-intensive seafood value chains. Based on successful research on the pH shift process at Chalmers, AquaFood was founded in 2021 and is now focusing on industrial process implementation, which could greatly increase resource efficiency in the seafood industry. In UP-SIDE, the objectives are to; (i) secure critical volumes of high-quality fish side streams for pH shift-based food production; (ii) improve the pH shift technology in terms of TRL, safety and resource efficiency; (iii) adapt the protein/oil products for a more diversified future food system.
