Additional information

Since calcium sulfate is an inorganic substance, it does not undergo biodegradation i.e. microbial degradation to carbon dioxide and water, since it doesn’t contain any carbon or hydrogen atoms in its chemical formula. Calcium sulfate will therefore be degraded in the environment by means other than biodegradation. The ions will dissociate; calcium will be assimilated by species in the water and is necessary to maintain a good chemical balance in soils, water and plants and the sulfate will become part of the sulfur cycle or be assimilated by microorganisms and other species that require sulfate as an essential substance in their biological systems/ processes.
