Singapore research team unveils bio-friendly method to extract chitin from crab shells

THE WHAT? A team of researchers at Singapore’s National University has discovered a bio-friendly way to extract chitin and chitosan from crab shells – a by-product of the shellfish industry, according to a report published by Bloomberg Green.

THE DETAILS The method, which uses water and carbon dioxide to extract chitin from cleaned shells is said to cut carbon emissions by up to 95 percent compared with chemical extraction.

The team is planning to trial the method at scale and is said to be in talks to build a facility in Vietnam that would commercialize the bio-friendly technique.

THE WHY? With 90 percent of the world’s shrimp, crab and lobster hailing from Asia, Vietnam is a sensible choice to trial the system. If the green procedure proves competitive, it could help the US$1.9 billion chiton industry become considerably more planet-friendly.
