5 million tons in 2011, and it is known that about 40% of this product (1 million tons) consists of wastes containing high levels of chitin (15-20%), proteins (25-40%), inorganic salts (ash 40-55%), and carotenoid pigments (about 15%) [6], Therefore, not only do these wastes contaminate the environment but also tons of products of great economic potential are being wasted.
