However, silica can be found in different types of biomass (inorganic ash). Recently, ashes of various (industrial) biowastes containing silica species, such as rice husk [9,10], bagasse, oil shale, fly, and wheat husk, have been used as a silica source for aerogel production. The company "Green Earth Aerogels" has commercialized the production of silica aerogels from rice husks already.
