What started with the basic concept of “Our food should preferably not be eating our food” resulted in an infrastructure converting vegetable-based waste streams into a high-protein feedstock for farmed fish. Between 2018-2022, Axfoundation carried out the project “Five Tons of Green Fish” in collaboration with the Swedish University of Agricultural Sciences (SLU) and actors from every step of the food chain. The project resulted in Sweden’s first green rainbow trout fed with a circular-based fish feed of mainly insects which, in turn, have been raised on a diet of food waste.
