Purpose and goal
The purpose of Fiskbajs was to design a solution that can convert fish farming residual stream into the fertilizers that a greenhouse today buys as NPK based on fossil raw materials. The project has successfully demonstrated two such solutions with positive side effects such as energy production, disruptive business models, increased circular production, which makes the licensing process for aquaculture easier and the production of fish and crops more cost-effective, where both units show a clearly reduced environmental impact.
Expected results and effects
Fiskbajs has achieved its target of goals where the establishment of the greenhouse in Höganös municipality has the opportunity to be based entirely on circularly produced and bio-based fertilizer, which facilitated the municipality´s process to enable the planning process for industrial production of food in urban environment. Furthermore, the energy that can be extracted in connection with biogas production is a strongly improving unit for the operations of the greenhouse, which completely reduces its need for purchased, costly peak-load energy.
Planned approach and implementation
The implementation and design has followed the analysis carried out by RISE at Gårdsfisk residual stream and then matched it to the nutritional need that Kullatomater has for its operations. With high overall knowledge in greenhouse cultivation, aquaculture and biogas technology, simple and robust solutions have been developed for further testing and evaluation. In a comprehensive approach, AWA compared the proposed solutions and produced an IP strategy and recommendation.
