“…The total mass loss and remained mass of SSP reported in this work were well consistent with those of the reference and theoretical data of CaCO 3 [3,[5][6][7]. The thermal property obtained indicates that SSP can be transformed to CaO by heating at above 752 °C, which is lower temperature than other shells (800 °C for oyster shell, 753 °C for golden apple snail shells, 900 °C for mussel shell and cockle shell) to obtain a final decomposition product [3,[5][6][7].…”

“…Figure 3 shows X-ray diffraction patterns of SSP and CA samples prepared from four different acetic acid concentrations. The XRD results were compared with those of calcium carbonate and calcium acetate reported in other literatures [3,21,23,27,47,48]. The XRD pattern of SSP clearly showed that the phase present was calcite, which was found to match with the JCPDS data file of CaCO 3 (File no.…”

“…The statistical data shows that many tons of scallop shells were annually disposed of. Over time, microbial decomposition appeared and progressively created very toxic gases such as NH 3 and H 2 S [3, 4]. Alarmed with these problems, the Ministry of Higher Education, Science, Research, and Innovation of Thailand has introduced the Bio-Circular-Green Economic Model or BCG to resolve these problems and financed projects for recycling these wastes, including establishing factories for calcium and fertilizers production to increase the recycling quantity of waste scallop shells (WSS) [5, 6].…”

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.

“…Figure presents the infrared adsorption results of the precursor and calcium lactates prepared by various lactic acid concentrations (40, 50, 60, and 70 wt %). The adsorption spectrum of the CaCO 3 precursor as shown in Figure a indicates the vibrational characteristic of carbonate (CO 3 2– ) anion that is presented in the crystal structure of CaCO 3 . − Some dominating adsorption peaks were explained in detail. An absorption peak at about 1440 cm –1 was assigned to the asymmetric stretching mode of the C–O bond, which is the major adsorption characteristic of CO 3 2– .…”

The scallop shell waste ( Pectinidae , one of saltwater clams) was used as a raw material (precursor) to prepare calcium lactate (Ca(C 2 H 4 OHCOO) 2 ), and the physicochemical properties of scallop-derived calcium lactate were then investigated. The scallop waste was first ground to obtain calcium carbonate (CaCO 3 ) powder, and the calcium lactate compounds were successfully synthesized by the reactions between shell-derived CaCO 3 and lactic acid (C 2 H 4 OHCOOH). The short preparation time, high percentage yield, and low-cost production are the preferred manners, and, in this research, it was the reaction of 70 wt % lactic acid and scallop-derived CaCO 3 . The thermal decompositions of both CaCO 3 precursor and all prepared calcium lactates resulted in the formation of calcium oxide (CaO), which is widely used as a catalyst for biodiesel production. By comparing with the literature, the results obtained from the characterization instruments (infrared spectrophotometer, X-ray diffractometer, thermogravimetric analyzer, and scanning electron microscope) confirmed the formation and crystal structure of both CaCO 3 and its calcium lactate product. The morphologies of calcium lactate show different sizes depending on the acid concentration used in the reaction process. Consequently, this work reports an easy, uncomplicated, low-cost technique to change the cheap calcium compound product (scallop CaCO 3 ) derived from shellfish waste to the valuable compound (calcium lactate), which can be used in many industries.

“…The soft tissue of shellfish also has the same limitation. However, the C and N contained within the mollusk shells can persist long term (Aubin, Fontaine, Callier, & Roque d'orbcastel, 2018;Fry, 2012), and these shells are mostly considered as wastes in the marine environment (Chen, Xu, Lv, Huang, & Jiang, 2018;Chung, Jung, & Park, 2020). If properly managed, these shells from shellfish aquaculture can be used as a longterm C and N sink.…”

Although Korea is third in seaweed production and second in shellfish production globally, this is the first study evaluating ecosystem services of seaweed and shellfish aquaculture in Korea. The objective of this study is to evaluate nutrient bioextraction capacities of major seaweed and shellfish species aquacultured in Korea. C (C) removal of three major aquacultured seaweed species, Neopyropia yezoensis, Saccharina japonica, and Undaria pinnatifida were 24,247, 8,423, and 12,758 tons, respectively, in 2016. N (N) removal of these species was 4,088, 732, and 1,244 tons, respectively. The C and N removal of the Pacific oysters (Crassostrea gigas) were 14,693 and 1,050 tons, respectively. Manila clams (Venerupis philippinarum) removed 2,120 tons of C and 136.5 tons of N. Together, 161,846 tons of CO 2 and 7,251 tons of N were removed by three major seaweed species and two shellfish species. These values are significant amounts, equivalent to 5.7% of CO 2 and 8.6% of N discharged from all wastewater treatment plants in Korea. These results suggest that nutrient bioextraction by aquacultured seaweed and shellfish can be a cost efficient, affordable, and equitable solution for coastal nutrient management programs in Korea and elsewhere.
