Chitin is a naturally occurring, white, hard, inelastic, nitrogen-containing polysaccharide that forms the structural component of the exoskeletons of insects, crabs, shrimps, lobsters, and other crustaceans, as well as the cell walls of certain fungi, algae, and yeasts. It is the second most abundant natural polymer after cellulose and consists of a linear polymer of (1→4)-N-acetyl-D-glucosamine. Due to its insolubility in water and many organic solvents, chitin is primarily used as a precursor for chitosan rather than as a direct industrial material.
Chitosan is produced through the deacetylation of chitin and has gained significant industrial importance because of its broad range of applications. It is widely used in the pharmaceutical, medical, cosmetic, textile, paper, food, beverage, and water treatment industries. Its notable properties, including biodegradability, biocompatibility, antimicrobial activity, non-toxicity, and non-allergenic nature, have contributed to its growing commercial demand. Chitosan is also used in wound care, dental surgery, textile sizing and dyeing, paper strengthening, and beverage clarification.
The report highlights that increasing demand for sustainable biopolymers, advancements in chitin processing technologies, and expanding applications in nanocomposites, biofuels, and water purification are driving market growth. Marine biomass, particularly shrimp and crab shell waste, has emerged as an important raw material source for commercial production. According to the report, the chitin market reached approximately $47.29 billion and is projected to reach $79.297 billion by 2028, with a CAGR of 5.07%, supported by continuous technological developments and expanding industrial applications.

Chitin is a naturally occurring polysaccharide found primarily in the shells of crustaceans and the exoskeletons of insects. It is also present in fungi, algae, and certain yeasts. Because it is the second most abundant natural polymer after cellulose, chitin is widely available and serves as the primary raw material for producing chitosan through a deacetylation process.
Chitosan is the deacetylated form of chitin. While chitin has limited direct industrial applications because of its insolubility, chitosan possesses improved functional properties and is used extensively in pharmaceuticals, medical products, cosmetics, textiles, paper manufacturing, food processing, and water treatment due to its biocompatibility and biodegradability.
Chitosan is used across multiple industries. It is applied in wound care, dental surgery, textile sizing and dyeing, paper strengthening, beverage clarification, agriculture, chromatography, food processing, pharmaceuticals, biomedical products, and water purification. Its antimicrobial and biodegradable characteristics make it valuable for sustainable industrial applications.
Shrimp shells, crab shells, prawn shell waste, lobster shells, and other crustacean by-products are the most common commercial raw materials. These materials contain high levels of chitin, making them suitable for extraction and subsequent conversion into chitosan using demineralization, deproteinization, and deacetylation processes.
Demand is increasing because these materials support environmentally friendly and high-value industrial applications. Their biodegradability, antimicrobial properties, compatibility with biological systems, and expanding use in nanocomposites, water purification, healthcare, and sustainable materials continue to drive commercial interest and market growth.
