CrustaTec is a Guatemalan company that produces a biopolymer made of shrimp shell waste, discarded by the industry, which can be used to remove textile dyes from wastewater. The chitosan biopolymer contained in the crustacean`s shell is an ideal absorbent and floculant for the dyes as it is non-toxic, biodegradable and also allows to recover the dyes for reuse. Since it is low-cost, it can be used by both large and small textile industries.

CrustaTec was part of the Young Water Solutions Fellowship in 2018.
