Rice husk is an abundantly available waste material in all rice producing countries. In certain regions this low value agricultural by product is used as a fuel for parboiling paddy in rice mills, it produced 13-15MJ/kg of energy. The partially burned rice husk in turn contributes to more environmental pollution. This rice husk contains nearly 20 percent silica, can be made into adsorbent material, which is used, in environmental remediation. Developed countries have accepted and followed the concept of “no waste” and all such materials are termed as “new resources” for new material development through value addition. In the present study hybrid precursor, which contains both carbon and silicon, used for the removal of heavy toxic metals, such as lead, copper and zinc present in wastewater .The efficiency of the hybrid precursor in the removal of heavy metals is approximately 90%.
