This book provides useful information and applications of biochar produced from agricultural waste for removal of contaminants from industrial effluent and reutilization of waste sludge in the production of biofuel/bioenergy. It describes how designer or modified biochar or combined application (biochar + microbes) can be applied successfully for reuse of wastewater and contaminated soil for ecorestoration, environment protection, and sustainable development. It also deals with the unique features, advantages, and disadvantages of techniques for biochar production and analyses. It underlines a road map in development of future strategy for pollution abatement and sustainable development. Features: Provides exhaustive coverage of biochar and its production and properties Highlights use of biochar in pollution control and environment protection Covers use of agricultural waste/waste biomass for dye decolorization and degradation Explores synergistic approaches for contaminants removal for better insights into basic and advanced biotechnological applications Describes how biochar treatment can be successfully applied for reuse of wastewater and contaminated soil ecorestoration and environment protection This book is aimed at graduate students and researchers in chemical/biochemical engineering, biotechnology, environmental sciences/engineering, and agriculture engineering.
