A new non-stick coating made from edible wax could help reduce waste by allowing all of the liquid to flow smoothly from the container.
Created by a team from Colorado State University, the non-stick coating is made from beeswax, in contrast to the fluorocarbon chemicals used to make many of the coatings used today. Beeswax has similar chemical properties to fluorocarbons, but is non-toxic, so is much safer for the environment. The team developed the coating by melting the wax and then spraying it inside the containers, where it easily repelled a number of different liquids, including tea, syrup and cola.
