Abstract

Waste generation during shrimp processing is a serious environmental and public health issue that has motivated the search for valorization alternatives such as chitosan extraction. Due to its properties, such biopolymer has been used in different sectors like pharmaceutic, water treatment and biomedicine. In this work, process simulation and environmental evaluation was carried out for the conversion of shrimp-derived chitosan into chitosan microbeads modified with thiourea. To this end, it was used the process simulation software Aspen Plus® and the waste reduction algorithm (WAR). Four cases were considered regarding contributions of energy and products. The conversion yield was calculated in 2 kg MPs-Thiourea/kg chitosan. The environmental evaluation showed that case 3 reached the highest total output impacts (1.23×10+3 PEI/h), followed by case 2, case 1 and base case. It was concluded that energy contributions are less than product contributions and the overall process is environmentally friendly for atmospheric and toxicological impacts.
