Sustainability: Don't waste seafood waste

Authors: Ning Yan& Xi Chen

Publisher: Nature

In developing countries, waste shells are often just dumped in landfill or the sea. In developed countries, disposal can be costly — up to US$150 per tonne in Australia, for example.

Yet shells harbour useful chemicals —protein, calcium carbonate and chitin, a polymer similar to cellulose, but which contains nitrogen (see 'Shell biorefinery'). The potential value of such shells for the chemical industry is being ignored. Scientists should work out sustainable ways to refine crustacean shells, and governments and industry should invest in using this abundant and cheap renewable resource.
