It has been used as building material, fertilizer, insulation material, or fuel. Combustion of rice hulls produces rice husk ash (RHA) which is a potential source of amorphous reactive silica. Most of the ash is used in the production of Portland cement.
Rice hulls (or rice husks) are the hard protecting coverings of grains of rice. In addition to protecting rice during the growing season, rice hulls can be put to use as building material, fertilizer, insulation material, or fuel. AND ANIMAL FEED
