Abstract
Due to rapid growth in population and industrialization, some new technologies are made for waste utilization and cost reduction in industrial processing by using rice husk (lignocellulosic biomass) as a valued material. In this paper various industrial and domestic application of rice husk and rice husk ash are discussed. Rice husk act as adsorbent for removing heavy metals from wastewater. In mostly countries of the world, lignocellulosic biomass used for bioethanol production because it is a renewable and environment friendly fuel. With the review, it is hope that researchers concentrate on producing non-food feedstocks.
