Yoshida Juken, a home building company in Omuta, Fukuoka Prefecture, has developed a method to improve the heat retention and insulating properties of exterior walls by using rice hulls. They’ve applied for a patent for their method, which utilizes material usually disposed of by incineration. The intent is to reduce greenhouse gases by reducing fuel consumption. The company has been working on the idea since January 2009.
