Biological wastes obtained from food, oyster shells, were recycled to calcium carbonate and then used as bio-green raw material to replace limestone/carbonate stone for calcium acetate (Ca(CH3COO)2·H2O) production. The conditions (ambient temperature occurred in an exothermic reaction, drying time, yield, and solubility) of the reaction between the bio …

Lime is an inorganic material which contains calcium. This material is predominated by carbonated, oxides, and hydroxides. It is also the name of the natural mineral (native lime) CaO which occurs as a product of coal seam fires and in altered limestone xenoliths in volcanic ejecta. (Krzysztof, 2013). Lime is the high-temperature product of the calcination of limestone. …

The sugar industry is inherently reliant on the use of lime as a clarifying agent, specifically calcium oxide. Oyster shells possess a high content of calcium carbonate, which can be converted into calcium oxide through high-temperature calcination. This process not only addresses the issue of solid waste pollution caused by discarded oyster shells but also yields …
