One advantage of land-based aquaculture is that emissions can theoretically be contained and reused. However, the techniques for doing so keep evolving. If the Nordic aquaculture industry is to grow in an environmentally sustainable manner, information is needed on the best available techniques.

The Nordic Council of Ministers therefore requested a report on the best available techniques for reducing and reusing emissions from land-based aquaculture. This report explores the state of play of Nordic aquaculture and takes stock of emerging and established techniques for reducing emissions and managing waste, with a focus on the circular economy. Improving waste management might improve the viability of land-based aquaculture, supporting the sustainable growth of this sector.
