1s4: Potential for carbon sequestration by using shells from aquaculture as building material
Shellfish are advocated for as a feasible option for a nutrient efficient protein source. Further exploitation for human application requires embedment in a circular designed food system, especially the application and embedment of the contributions of carbon and nutrients. The shells, that often are considered a waste product could be used as source of calcium carbonate that is essential in concrete and traditionally collected by mining. In a running project we investigate the applicability of shells from aquaculture in building material. The application of shells in building constructions holds the advantage that the included carbon is sequestrated for a longer time.Â
