Nanomaterial Fabrication from Paddy Straw for Bioethanol Production

The depletion of natural resources and the relatively small carbon footprint they generate are the main reasons for the push for renewable energy sources. Because they are renewable and emit little carbon dioxide, biofuels are considered the best prospects for use as alternative energy sources. Furthermore, the lack of effective processes and technologies makes large-scale bioethanol synthesis time-consuming. Pretreatment of the rigid and inflexible agro-industrial waste to release sugars is a mandatory step for ethanol production. Previously, this was achieved through chemical, biological, and physical processes that required expensive solvents and chemicals, large amounts of energy, effective organisms, and high temperatures and pressures to release the tightly bound configuration of the substrates. The production of unfavorable and inhibitory compounds as well as equipment degradation is caused by these expensive and complex technologies. Nanotechnology has been extensively studied for its potential to improve biofuel production methods due to its superior adsorption, catalysis, and reactivity capabilities. The role of these advanced nanotechnologies and associated nanoscale elements in biomass conversion as well as their impact on yield and bioethanol production processes are elaborated in this chapter.
