Biochar

This book highlights the latest research on biochar, a low-cost carbonaceous material produced from biomass, and is regarded as an economical substitute to the activated carbon. The book describes the production and the characteristics of biochar through various techniques/methods such as pyrolysis, gasification, torrefaction, and hydrothermal carbonization of carbonaceous biomass, such as agricultural residues, algal biomass, forest residues, manures, activated sludge, energy crops, digestate at high temperature (300–900 °C) and under O2-limiting conditions. The book also highlights the several unique properties of biochar such as an efficient, cost-effective, and environmentally-friendly material for diverse contaminants removal. The variability in physicochemical properties (e.g., surface area, micro-porosity, and pH) provides an avenue for biochar to maximize its efficacy to targeted applications. This book interests academics working in the development of green and sustainable technology in agricultural engineering, material science, chemical engineering, and environmental science.

Dr. Showkat Ahmad Bhawani is presently working as an associate professor at the Department of Chemistry, Faculty of Resource Science and Technology, UNIMAS Malaysia. In addition to this, he has a teaching experience of two years from King Abdul Aziz University-North Jeddah and a post-doctoral experience of three years from the Universiti Sains Malaysia, Malaysia. He received his M.Sc. in Analytical Chemistry and Ph.D. in Applied Analytical Chemistry from Aligarh Muslim University, Aligarh, India. He is working on the synthesis of molecular imprinting polymers for the removal/extraction of dyes, fungicides, and various natural products from environmental and biological samples. In addition to this, he is also working on the development of new test methods and determining standard conditions for analysis (separation, isolation, and determination) of various analytes from environmental and biological samples.
