Green mussel shells contain a high content of calcium that can be potentially used for starting biomaterials. A powder processing and subsequent calcination-dissolution-precipitation (CDP) technique for recycling the shells into the value-added of precipitated calcium carbonates (PCC) is presented in this paper. In the experimental study, the received green mussel shells were initially washed and ground and followed by heat treatment at different temperatures in an electric furnace. PCC product was precipitated from the blended solution of calcium and carbonate ions derived from the heat-treated ground powder. The precipitating solids were then investigated via XRD, SEM-EDX, and FTIR methods. The XRD Rietveld method confirmed that the raw green mussels were rich in crystalline aragonite, which could be recycled into vaterite and calcite in the PCC product. The current study demonstrated that the green mussel shells are technically possible for the starting materials in biomedical applications. © 2021 Elsevier B.V.
