Significant part of fish carcass waste is discarded as common organic waste in sanitary landfills or simply discarded into rivers or ponds. This strongly impacts the environment causing environmental, economic and public health problems. On the other hand, the bone of the fish carcass is a bio-waste rich in calcium. Therefore, it has great potential to be valorized as an alternative calcium precursor in the synthesis of calcium phosphate based biocements for regeneration or replacement of the bone tissue in medical and dental applications. The present work had as main objective to synthesize and characterize calcium phosphate biocement of tilapia carcass bio-waste. Initially, the tilapia carcass bio-waste was benefited (cleaning, drying, comminution, and sieving) and then characterized in terms of chemical composition and X-ray diffraction. Subsequently, the calcium phosphate biocement was synthesized by the wet precipitation process using acid / base to form the precipitate, followed by heat treatment at 900 °C for 2 h. The synthesized biocement was characterized in terms of X-ray diffraction, crystallite size analysis, FTRI, chemical composition, and SEM. The experimental results indicated that biocement of nanocrystalline ?-calcium pyrophosphate was obtained from tilapia carcass bio-waste. Therefore, the tilapia carcass bio-waste can be valued as a high value-added bioceramic. |
