In rural societies, agriculture and cultivation are considered as the primary livelihood of the individual. Recent development of harvesting in agriculture yields huge amounts of agro-residue as wastes. Converting these crop- residue to dynamic activities in rural areas will aid in procuring silica in an eco-friendly and cheap manner thereby improving the livelihood of the villages which in turn leads to the development of the nation. Naturally, silicon found as oxide form (silica) and as silicates, were used as fertilizers, energy storage devices and adsorbents. In this study, non-conventional sources-sesame oil cake and pearl millet wastes were utilized as a silica source for the generation of mesoporous siliceous materials. This study mainly focussed on synthesising amorphous silica from agro-waste and have compared the agro- based silica with commercially available silica. The characteristics of the mesoporous silica have been determined by Fourier Transform Infrared spectroscopy, X- ray diffraction, Scanning Electron Microscopy and Energy Dispersive X-ray spectroscopy. This study explored the antibacterial potential of the as synthesised mesoporous silicates. The conversion of waste to wealth as this is a versatile, facile method of conversion that can be carried out easily. When relative to the precursor, as- synthesised silica source made from agricultural waste showed much better antibacterial activity.
