Abstract Scope |
In the recent scenario, when the world economy is falling due to the spreading of the coronavirus, three R’s – Reduce, Recycle and Reuse are very important factors. In this context, waste management and their conversion in value-added products is a key feature to implement the three R’s formula. To achieve the goal of sustainable development, biomass is considered an alternative source for non-renewable. In the present report, two different agriculture wastes are used for the extraction of SiO2. Rice husk (RH) and Rice straw (RS) are taken as precursors for SiO2 production. Further, two different extraction methods including chemical and biological routes are employed to extract SiO2. The obtained SiO2 was characterized by various experimental techniques like X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy. |
