New Fjell Tech Agenda: Turning Fish Sludge into Future Feed

December 2025

Fish sludge - From waste to feed?  

We’re excited to announce the release of our latest Fjell Tech Agenda paper: “Fish Sludge: From Waste to Feed?” written by Researcher Nina Liland at Institute for Marine Research. 

This edition dives into one of aquaculture’s hottest topics—how fish sludge, once seen as a waste problem, could become a valuable resource in the circular bioeconomy. The paper explores the promise (and challenges) of upcycling sludge into feed for insects and other uses

Curious about how fish farming waste could become valorized as a potential byproduct? Dive into the science and research, the hurdles, and the future potential of transforming waste into value.
