Effect of heat treatment on the cellulose-calcium silicate nanocomposites synthesis from waste wood, clam shell, and glass

Abstract

Cellulose-calcium silicate (CCS) nanocomposites were fabricated through an environment-friendly process from waste wood, glass, and clam shells. Effect of heat-treatment on synthesis of CCS nanocomposites was investigated in terms of the precursor ratio and firing temperature. The optimization of cellulose, silicon, and calcium ratio resulted in the low temperature synthesis and also reducing input energy and the production of toxic by-products. The synthesized CCS nanocomposites were examined for its versatility, especially regarding its ability to replace plastics. The resulting biodegradable material has the potential for use in a variety of applications, including reducing CO₂ emissions.
