Abstract: This invention relates to a method and apparatus for the processing of shellfish waste meal. More particularly, to increasing the crude protein while decreasing calcium and phosphorus levels of shellfish waste meal. The method significantly reduces the percent calcium and phosphorus in shellfish waste meal by introducing a strong acid while lowering the ratio of calcium to phosphorus and raising or maintaining protein levels of the shellfish waste meal at a neutral pH level.
