Glanris is a startup that turns rice hulls into a high-performance hybrid water filtration media that can remove metals and organics. Rice hulls are the hard protective coverings on grains of rice and are a common waste product. Currently, rice hulls around the world are burned, resulting in the release of greenhouse gases. Glanris diverts this waste and instead uses it as a filtration method that is faster and cheaper than traditional water filters. Learn how this method can be used in industrial and residential settings.
