Fiskavfall

Fiskavfall refers to the waste materials generated from the processing of fish. This includes byproducts from fish catches, such as scales, fins, bones, gills, and viscera, as well as processing residues like trimmings and leftover flesh. The composition and quantity of fiskavfall vary significantly depending on the type of fish, the fishing methods employed, and the processing techniques used.

Historically, fiskavfall was often discarded into the environment, leading to pollution and potential ecological damage due to decomposition and nutrient enrichment. However, there is a growing recognition of the potential value and the need for sustainable management of these materials. Modern approaches focus on reducing, reusing, and recycling fiskavfall.

Applications for fiskavfall are diverse. It can be used as a source of protein and nutrients in animal feed, particularly for aquaculture and livestock. Furthermore, it is a valuable raw material for the production of fishmeal and fish oil, which are utilized in various industries. Research is also exploring the use of fiskavfall in the extraction of collagen, gelatin, and bioactive compounds with potential applications in pharmaceuticals, cosmetics, and food supplements. Composting and biogas production are other methods for managing and valorizing fiskavfall, converting it into organic fertilizer or renewable energy. Effective management of fiskavfall contributes to a more circular economy within the fishing and aquaculture sectors.
