Chitin and Chitosan harvested from crustacean shell waste

Chitin and chitosan are biodegradable polymers that are extracted from the shells of crustaceans such as shrimps, shellfishes, crabs and lobsters. These seafood wastes are usually discarded unfortunately, but instead they should be collected from food companies and households because they have numerous benefits otherwise.

  • Besides food companies and households restaurants could also be a source for these kind of wastes.
