This reference book provides advanced knowledge on sustainable biogenic waste management. It covers innovative waste processing technologies to produce biofuels, energy products, and biochemicals. To create a circular bioeconomy, it is imperative to develop processes where the waste generated through one process acts as a feedstock for the other. This book discusses the latest developments in biochemical and thermochemical methods of conversion and covers the potential of different kinds of biomass in more decentralized biorefineries. It describes sustainable solutions for a greener supplement to fossil resources. The book is meant for microbiologists, chemists, and biotechnologists.
