Wastewater Treatment with Biochar: From Fundamental Research to Technical Developments and Applications provides an overview of challenges and opportunities for biochar as adsorbents to contribute to carbon neutrality. The book offers new perspectives on how to strengthen wastewater treatment through CE and resource recovery. It also explores how biochar can contribute to carbon neutrality in the framework of the CE. By identifying existing knowledge gap, the book uncovers new research directions for further development in closing the loops by implementing the circularity of the biochar. Wastewater Treatment with Biochar: From Fundamental Research to Technical Developments and Applications meets the need of societies, university students and policy makers on scientific/engineering approaches to deal with water pollution problems. The book disseminates knowledge on how to contribute to emerging understanding in the biochar with respect to the relationship between materials’ structure and adsorption performance that paves the ways for a new direction of water technology in the future for wastewater treatment.
