The textile industry is one of the most important economic activities in Guatemala. However, its negative impact is high, due to the frequent discharge of dyes into the waterbodies.

Isabel (26) has developed a filter that applies the biopolymer chitosan obtained from the shrimp shell waste as a low-cost adsorbent for the removal of textile dyes from wastewater. This polymer can be easily obtained from the waste of shrimp shells, which the Guatemalan shrimp industry discards. It presents all the characteristics of the ideal adsorbent, providing a solution to big and small textile industries for the remediation of water contaminated with dyes before being discharged to water bodies. It also allows craft makers to reuse their dyes. Isabel is at the moment adapting it for its use in textile industries as well as local craft makers in the rural areas.
