The book discusses the commercial applications of biochar and its composites. Biochar prepared from pyrolysis of waste biomass is gaining widespread attention in environmental remediation due to its multifaceted benefits. This book explores these possible applications of biochar in water treatment and removal of pollutants from the contaminated sites. It also emphasizes the role of biochar engineering through different physical and chemical methods to enhance structural and physicochemical properties of biochar such as surface area, porosity and surface functional group. It also focuses on the diverse source of biomass that can be used for biochar production, different methodologies for biochar preparation and biochar engineering for improvement of its properties. Finally, it describes all the applications of biochar that can contribute to environmental remediation and sustainability. Given the contents, the book will be useful for students, researchers and professionals in the area of environmental chemistry and material science.
