And in case you’re wondering, they don’t taste like chicken; instead, they’re often described as having a nutty flavor and a shrimp-like texture once they’re out of their shell. Before you ...
Commercially, chitin is extracted from the shells of crabs, shrimps, shellfish and lobsters, which are major by-products of the seafood industry. [2] [3] The structure of chitin is comparable to cellulose, forming crystalline nanofibrils or whiskers. It is functionally comparable to the protein keratin. Chitin has proved useful for several ...
It is made by treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide. Chitosan has a number of commercial and possible biomedical uses. It can be used in agriculture as a seed treatment and biopesticide, helping plants to fight off fungal infections.

The powdered shells of crustaceans are processed to acquire chitin, a polysaccharide found in the shells, from which chitosan is derived via deacetylation. Water that is more brackish, or saline requires larger amounts of flocculant. Flocculation is often too expensive for large operations. Alum and ferric chloride are used as chemical flocculants.
New research shows that adding shrimp shells to cement makes it stronger and more environmentally friendly. How did we come up with this combo?
Fertilizer: Fish byproducts can be used to produce both solid and liquid fertilizers. Solid fish waste can be composted, added whole or grounded and placed on soil to add nutrients. Fish waste can also be emulsified and used to create fish based liquid fertilizers.
Since fish emulsion is naturally derived, it is considered an organic fertilizer appropriate for use in organic horticulture. In addition to having a typical N-P-K analysis of 5-2-2, fish emulsion adds micronutrients. [2] Fish emulsion, applied as a liquid fertilizer, is also used when growing roses to enhance the bloom color of the flowers. [3]
