Biofuels an option for agro-waste management

Agricultural residues or/and the postharvest by-products generated via different production processes of agriculture are known as agriculture-originated wastes (agro-wastes), which have the potential to be a promising source of energy and feedstock for the production of high value-added chemicals and other substances. Therefore, it remains a major obstacle for today's society to seek cost-effective strategies in addressing the ongoing issues associated with agro-wastes. The benefits and advantages of agro-waste processing and refining methods are believed to be cost-effective and eco-friendly, as well as could contribute positively toward more sustainable waste management and less-carbon intensive energy utilization path. Indeed, this chapter presents agro-waste-to-biofuel strategies that play a critical role in managing a circular economy, in which the system would effectively eliminate waste by adopting the continued use of resources. Promoting the benefits of the agro-waste-to-biofuel approach and the advantages of embracing the basic tenets of a circular economy can provide incentives for farmers, agro-business owners, and other stakeholders to embrace more sustainable practices in not only modernizing the sector but also contributing toward the overall sustainable development of the economy and society at large.
