Chitin and chitosan from shellfish waste and their applications in agriculture and biotechnology industries.

A shellfish processing plant generates only 30-40% of edible meat, while 70-60% of portions are considered inedible or by-products. This large amount of byproduct or shellfish processing waste contains 20-40% chitin, that can be extracted using chemical or greener alternative extraction technologies. Chitin and its derivative (chitosan) are natural polysaccharides with nontoxicity, biocompatible, and biodegradable properties.
