From waste to commodity: transforming shells into high purity calcium

The valorisation process is aimed at turning shell waste into calcium carbonate by eliminating water, salt, mud and remaining meat contained in the mussel shell, which are the cause of the related effects of the decomposition of the organic matter and the generation of leachates. Fig. 2 shows the meat attached to the crushed shells.The same scenario is seen globally with egg production expected to stay steady or progress modestly among the major markets around the world (Conway, 2018a).In the past 30 years, egg production has grown up by more than 150% and greater progress was noticed in Asia where production has expanded by four-folds (FAO, 2020).In India, Channelling eggshell waste to valuable and utilizable

Oyster Shells: A Nutritious And Safe Source Of Calcium

The dumor oyster shell hails from the Northeastern shores of the United States and has been used for centuries as a source of food and shelter for oysters. The oyster shell is composed of calcium carbonate, which is also found in the shells of other marine creatures such as crabs, lobsters, and shrimp. The calcium carbonate is what Oyster shell waste contains abundant calcium ions (37.4% of dry weight) making it an economical calcium source for bio-concrete substrate (Kwon et al. 2004). Up to 96% of oyster-shell components are composed of calcium carbonate, which can be treated with acidic solutions to release the calcium ions (Yoon et al. 2003).Agricultural by-products and oyster shell as alternative
