Biofuel for Modern Farming

Abstract

Agriculture remains one of the most energy-intensive sectors, so the adoption of green energy technologies
offers a sustainable pathway to transform modern farming. Roughly, 180–240 million tonnes of crop
residues remain after their conventional applications, yearly, in India’s agrarian system. An intimidating 92
million tonnes are combusted in the open every year, which causes adverse effects, including the emission
of greenhouse gases that contribute to global warming, increased levels of smog that beget health hazards,
loss of biodiversity of agricultural lands, and the deterioration of soil fertility. Bioethanol, compressed
biogas, biodiesel, and advanced biofuels can be made from remnants such as paddy straw, wheat stubble,
maize stalks, and sugarcane bagasse through the application of highly advanced technologies such as
enzymatic hydrolysis, anaerobic digestion, and production of cellulosic ethanol. Biofuels derived from crop
remains – similar to biogas, bioethanol, and biodiesel – not only provide renewable energy but also produce
fresh income aqueducts for farmers, reduce dependence on fossil fuels, and support a circular economy
in agriculture. This poster emphasizes the prospects for residue-grounded biofuels as a green technology
movement in contemporary agriculture, looking into the metamorphosis of what had been deemed as waste
material into a source of renewable energy. Emphasizing key results, identifying new trends, and proposing
directions for future research to grease crop residue retention to be embraced and maximized to make
sustainable and eco-friendly agricultural practices in today’s agricultural ecosystem.
