Abstract
The management and disposal of agro-wastes are the major environmental problems nowa-days and presence of substantial quantity of silica in agro-wastes made them possible to convert waste into valuable fertilizer materials. The present study aimed to extract silica from various agro-wastes such as paddy straw (PS), sugarcane bagasse (SB), maize cobs (MC) and coconut husk (CH) by exposing to various calcination temperatures (500o C, 600o C and 700o C) and characterized through XRF, FESEM-EDAX, TEM, FT-IR, XR-D and other basic properties. The recovery of silica from paddy straw calcined at 700o C was higher than that of other temperatures and sources tested.
