Edible, biodegradable fibers made from milk protein, cellulose

Milk protein and cellulose derived from plants may be the next big thing in sustainability, thanks to a first-of-its-kind advancement made by researchers at Penn State. Using a manufacturing technique called electrospinning, the team created nanofibers 1,000 times thinner than a human hair and then manipulated those fibers into mats that hold promise for a variety of products, like biodegradable — and even edible — food packaging.
