Leather is a fantastic material who's use has been pervasive through most of human history. But it's production is a scourge on the environment due to both the methods used to tan it, and the source of the starting material. In this video we explore a method for making a leather like material, without harming the environment, and without having to harm any animals. The starting material is a waste product from a drink that is becoming increasingly popular: Kombucha. As kombucha cultures grow, a layer of cellulose and proteins grow on the surface of the liquid. With a bit of simple processing, this layer can be transformed into an incredibly strong and flexible material that looks and feels like real leather.

This research was made possible by Scihouse and this is far from the last you'll be seeing on this topic. All of us at scihouse are very excited about this technology and are working hard to continue to improve and develop it.
