Abstract:
Production of Nordic Salmon has become an industry with continuous growth and the aim to exceed oil and gas in terms of Norwegian export value in 2030. This rapid growth in a traditional farm-based production has required need for regulations and technical solutions in order to handle both waste water treatment and sludge handling. Scanship has successfully transferred technical solutions from waste handling at cruise ships to the land-based fish farming. The solution is dewatering and drying of sludge to a stable bi-product. This will reduce transport cost and make it possible to store the product over longer periods in the remote fjord areas of the Norwegian west coast. As part of the solution Scanship has established collaboration with end users for the reuse of sludge as a bi-product. The different areas where the bi-product has become a value are within fertilizer, biogas and incineration. The nutritious rich product with high energy content makes it a high-quality biproduct.
