Biochar for Environmental Remediation: Principles, Applications, and Prospects synthesizes state-of-the-art knowledge on biochar-based systems for environmental remediation. The book examines a wide variety of biochar applications for the remediation of inorganic, organic, microbial and emerging contaminants in various environmental media, including drinking water, industrial wastewater, urban stormwater, industrial and indoor air pollution, and contaminated lands and soils. Researchers, engineers and graduate students will find this to be a valuable reference for understanding opportunities for the use of biochar in environmental remediation as it fills the gaps in existing literature and offers a clear roadmap to guide future research.

An increasing body of evidence shows that biochars have potential applications in environmental remediation of contaminants in soils, aqueous systems, and air pollution control. This book uses a systematic approach, covering biochar preparation, properties and characteristics, removal mechanisms, industrial applications, regeneration and disposal of spent biochar, lifecycle analysis and environmental and human health risks.
