Valorization of Microalgal Biomass and Wastewater Treatment provides tools, techniques, data and case studies to demonstrate the use of algal biomass in the production of valuable products like biofuels, food and fertilizers, etc. Valorization has several advantages over conventional bioremediation processes as it helps reduce the costs of bioprocesses. Examples of several successfully commercialized technologies are provided throughout the book, giving insights into developing potential processes for valorization of different biomasses. Wastewater treatment by microalgae generates the biomass, which could be utilized for developing various other products, such as fertilizers and biofuels.

This book will equip researchers and policymakers in the energy sector with the scientific methodology and metrics needed to develop strategies for a viable transition in the energy sector. It will be a key resource for students, researchers and practitioners seeking to deepen their knowledge on energy planning, wastewater treatment and current and future trends.
