Nitroshrimp: garnalenafval omzetten in biobased meststoffen
Een team van UM-studenten afkomstig van de bacheloropleiding Business Engineering en het Maastricht Science Programme, plus studenten van de master Biobased Materials heeft de 2e plaats behaald in de Nederlandse voorronde van Biobased Innovation Student Challenge Europe (BISC-E) Competition 2022.

BISC-E encourages students to develop innovative biobased products and processes. Team Nitroshrimp presented the laboratory proof of concept of converting shrimp waste into biobased fertilizers, together with a life cycle assessment and a business plan. The competition mainly assessed technical and economic feasibility of the idea.
Chitin, the second most abundant biopolymer on Earth
Chitin is a polymer mostly found in crustaceans, but also in exoskeletons of other animals. It is a large waste stream, in the Netherlands for example more than 3000 Tons annually generated from shrimp waste alone in which the majority is not used.

Nitroshrimp, including three students from the Biobased Materials Masters, found a way to convert this polymer into an N-fertilizer which can also be used for the preparation of value-added chemicals. To this day, N-fertilizers are prepared through the Haber-Bosch process, responsible for 627 million metric tons of CO2 yearly emission. By replacing this process alleviates the environmental burden and facilitates the transition towards a sustainable biobased economy.
