Abstract
Active chitin is recovered from shellfish waste in a mechanical process without chemical additives. Shellfish waste is subjected to drying followed by grinding and treatment in an air classifier to separate the same into two major components, one being predominately active chitin and the other being a heavier component of predominately protein and calcium carbonate, which is an enhanced protein meal. A screening process for the first major component further separates most of the calcium salts from the active chitin, and all components are then packaged and stored for further use.
