In Malta, consultancy firm AquaBioTech Group has joined forces with industrial partners and research institutes in Denmark, Norway, Iceland and Greenland for a three-year project called PROFIUS. It’s being funded by Blue Bio ERA NET and coordinated by Dr Ann-Dorit Moltke Sørensen at the Technical University of Denmark. The project aims to address challenges that prevent the reutilisation of lumpfish (roe and carcass) and tuna side-streams and to find new ways to use these by-products.
