Rice husk is an organic waste and is produced inPerfect quantities. It is a major by-product of the rice milling and agro-based biomass industry. Rice husk is a cellulose-based fiber and contains approximately 20% silica in amorphous form (Hu et al., 2008; Mansaray & Ghaly, 1998; Nair, Fraaij, Klaassen, & Kentgens, 2008; Ndazi, Karlsson, Tesha, & Nyahumwa, 2007).
