Sustainable Chitosan-Recovered Aquaculture Feed

Pennotec (Pennog Ltd) has led a successful Cefas Seafood Innovation Fund Technical Feasibility project. Through this project we were able to demonstrate that our wholly biodegradable solid-liquid separation aid chitosan could be used to selectively remove proteins and oils from fisheries processing effluent. Chitosan formulations are derived from crustacean shell by-product, using Pennotec’s sustainable bio-refinery technology platform.

Our follow-on collaborative Research and Development project with Sustainable Feeds Ltd  evaluated the performance of recovered protein and oil from fishery effluents and bio-solids captured from aquaculture as feed sources for polychaete worm cultivation. This project is a highly innovative Circular Economy opportunity to convert aquaculture wastes into a new and sustainable source of high value aquaculture feed.
