This book covers the various technological developments and challenges in converting biomass residues into different forms of bioenergy. The continuous increase in the world population increased the demand for food products. The incorporation of modern technologies in agriculture increased the production of various food products, ending with excess generation of agricultural biomass residues from primary and secondary agriculture industries. Since, these biomass residues are a rich source of valuable bioproducts, they can be converted into various forms of bioenergy, such as biogas, biochar, biooil, biodiesel, and bioethanol. Besides, this approach is expected to address the gaps in biomass residue management and transformation to valuable bioproducts, and it also enhances the circular economy perspective. The book can be a valuable reference for beginners, researchers, and professionals interested in sustainable construction and allied fields.
