The NIBIO report was developed on behalf of Andøytorv AS and Andfjord Salmon AS. The research institution explored both opportunities and limitations related to the use of fish sludge from Andfjord Salmon as a CO2-reducing component in products like growth media, soil improvers and fertilizer products for agriculture, gardening and other relevant areas of application.In this context, fish sludge means fish feces and leftover fish feed that sinks to the bottom of the land-based farming facility at Andøya, which in turn is collected by cleaning robots.
The NIBIO report concludes that dried fish sludge from Andfjord Salmon’s land-based farming facility has the properties required to satisfy the treatment requirements set in current regulations. This will still be valid after the expected upcoming revision of Norway’s fertilizer regulations. Thus, the fish sludge has many potential areas of application. As an example, fertiliser made from dried fish sludge can be used as an additive in growth media such as organic and organo-mineral fertilisers, used on agricultural land, for gardening, and other agricultural purposes.“
To reuse biological waste is both sustainable and profitable. We will use NIBIO’s recommendations in our continued efforts to explore the compelling commercial opportunities our fish sludge brings”, says Rasmussen.Andfjord Salmon has developed an innovative and sustainable patented aquaculture concept for land-based farming of Atlantic salmon. The company’s flow-through facility is escape-proof, lice-free and its innovative cleaning system avoids polluting marine life. Additionally, the facility will be partly powered by the use of solar panels and wind turbines.
