University of Gothenburg researchers see fish solid waste as good biogas feedstock

In Sweden, digesting fish waste can allow circular fish and vegetable farms (aquaponics) to produce biogas that can be fed back into the energy system of these farms. This also generates excellent nutrition for plants, according to new research from the University of Gothenburg.

The solid waste of fish has been a byproduct with no particular value until now. But a research project at the University of Gothenburg has used the waste to make biogas that can contribute to meeting the energy needs of the aquaponic farms. This is described in Victor Lobanov’s work published in the journal Aquacultural Engineering.
