There is an increasing demand for environmentally sustainable sourcing of ingredients for the food, pharmaceutical and supplements industries. In the case of calcium carbonate (E170) as by-products from the egg and shellfish processing industries these have the potential to be sustainably sourced. In addition to their green credentials, biogenic carbonates have intrinsic benefits in terms of their chemical composition, such as a low heavy metal burden. However, their biogenic origin can potentially lead to manufacturing issues such as higher levels of co-mineralising components and the organic templates of their natural production. This contribution identifies the regulatory barriers to the adoption of biogenic eggshell calcium carbonate by assessing materials from biological sources along with commercial precipitated and ground carbonates against current regulatory standards.
