“…In the agricultural field, it has been used as a soil amendment, a plant micronutrient, foliar fertilizer, and a soil pH adjuster [35]. More recently, CA has been used to alleviate yield loss in rice [36] and determine the potential acidity of tropical soils [37]. For other applications, CA has been used as starting reagent to return to common compounds such as nano CaO [38] and CaCO 3 [39] and prepare other compounds such as calcium phosphates [40], acetone [41], composite ceramic compounds [42], anhydrite calcium sulfate nanowhiskers [43], and cement mortar [44].…”

The search for sustainable resources remains a subject of global interest. Calcium acetate used in many fields was prepared using waste scallop shell as a raw material, and its physicochemical properties were investigated. The waste scallop shells were transformed to calcium acetate compounds by reactions with four acetic acid concentrations at ambient temperature until the completely dried powder is obtained. The maximum yield of 87% with short reaction time at a low temperature was observed in the reaction of 60%w/w acetic acid with scallop shells. Thermal transformation reactions of all prepared calcium acetate samples revealed temperature conditions for heating to produce other advanced materials. FTIR and XRD results confirmed the purity and solid phase of all prepared calcium acetate samples, and they were compared with those of literatures and found to be well consistent. The obtained timber-like particles have different sizes depending on the acetic acid concentration. This work reports an easy and low-cost method with no environmental effect to produce cheap calcium products to be used in the industry.

Bio-green synthesis was designed and employed for calcium acetate monohydrate (Ca(CH3COO)2·H2O) preparation. Biological wastes obtained from food, oyster shells, were recycled to calcium carbonate and then were used as bio-green raw material to replace limestone/carbonate stone for calcium acetate production. The conditions (ambient temperature occurred in an exothermic reaction, drying time, percentage yield, and percentage solubility) of the reaction between the bio-green CaCO3 and three different acetic (CH3COOH) concentrations (8, 10, and 12 mol·L−1) were investigated. The maximum percentage yield (93.42%) with a shorter drying time (18 h) affected the low cost of the product found in the reaction between the bio-green CaCO3 with 12 mol·L−1 acetic acid. The percentage solubility and chemical compositions without any toxic metal impurity revealed by the XRF technique would be useful to suggest use in the specific application. The XRD, FTIR, and TGA data of Ca(CH3COO)2·H2O prepared by the bio-green CaCO3 obtained from oyster shell wastes in this work and those in previous works used other calcium sources were consistent. The morphologies with different sizes of the obtained Ca(CH3COO)2•H2O depend on the CH3COOH concentrations reported in this work and were different from those reported in previous works because of different calcium sources. According to the observation, it can be concluded that the low-cost and bio-green technique without the environmental effects was successfully applied to produce cheap Ca(CH3COO)2•H2O and reduce greenhouse gas emissions, which can be used in the specific industry.
