Shrimp shells to mine uranium from the ocean

Jennifer Newton writes about a hot Green Chemistry article for Chemistry World

Shrimp shells that would otherwise be thrown away by the seafood industry have been turned into tough fibres that can harvest valuable metals from water.

Robin Rogers, and his team at the University of Alabama in the US, had long been interested in using ionic liquids to process cellulose but the Deepwater Horizon oil spill in 2010 encouraged them to try something similar with chitin, the structural biopolymer that makes up the shells of various crustaceans. ‘We started working with the Gulf Coast Agricultural and Seafood Co-Op in Bayou La Batre, looking at uses for their shrimp shell waste, about the same time as the moratoriums on shrimping. It was quite clear that new products and profits were needed.’
