New biodegradable alternative for food from food waste

A material made up of a mix of crab shells and tree fibres has been developed for use in food packaging, comprising the two most abundant biopolymers – cellulose and chitin. Researchers at Georgia Institute of Technology, USA, aimed to produce a thin film that could rival the highest grades of polyethylene terephthalate (PET), showing up to a 67% reduction in oxygen permeability in comparison, meaning that it will keep food fresher for longer.
