A cracking idea

A big theme in textiles and materials development at the moment is sustainability and recycling so this story about egg packaging made of eggs has scrambled our minds.

Researchers as Tuskegee University added egg shell nanoparticles (350,000 times smaller than the diameter of a human hair) to a plastic polymer consisting of 30% PLA (polylactic acid, a polymer derived from cornstarch) and 70% PBAT (polybutyrate adipate terephthalate, a petroleum polymer that, unlike other oil-based plastic polymers, is designed to begin degrading as soon as three months after it is put into the soil). This resulted in a material that was 700% more flexible than other bioplastic blends and this pliability could make it ideal for use in retail packaging, grocery bags and food containers — including egg cartons.

How amazing to be able to make a valuable material out of a waste product!
