Preface

The widely recognized terminology of biochar was first introduced in 2006, and has become increasingly important as a green and carbon-negative solution to some global problems, such as climate change and environmental pollution. The potential capacity of biochar as an effective, low-cost, and environment-friendly adsorbent and catalyst to remove various pollutants, which is related to its relatively large surface area and abundant surface functional groups, was quickly unveiled afterward. Seventeen years on, numerous scientists have worked on biochar technology, and it is proven that biochar with a science-informed and fit-for-purpose design can serve a promising agent for wastewater treatment. The booming biochar market in current years renders biochar a ready-to-implement technology for smart and sustainable wastewater treatment.

In this book we summarize recent research development on biochar production and emerging applications with a focus on the value-added utilization of biochar technology in wastewater treatment, succinctly summarizing different technologies for biochar production and characterization with an emphasis on feedstock selection and pre/post-treatment. The text discusses the mechanisms of biochar’s various roles in different functions of wastewater treatment (i.e., adsorption, biofiltration, anaerobic degradation, sludge dewatering, sludge composting, nutrient recovery, advanced oxidation process, odor control, removal of pharmaceuticals and personal care products, removal of emerging contaminants, fate and transport in the environment, and life cycle assessment). It includes the latest research advances in manufacturing optimization and improvements to update the carbonaceous materials with desirable environmental functionalities.

Discussion and case studies are incorporated in treating municipal wastewater, industrial wastewater, agricultural wastewater, and stormwater to illustrate and emphasize the promising prospects of biochar technology in the treatment of various wastewater in actual utilization. Perspectives and future research directions of the emerging biochar technology in wastewater treatment are presented to provide insights for readers and researchers in biochar application for wastewater treatment.

State-of-the-art knowledge of biochar technology is crucial to sustainable wastewater treatment. Given our global targets of carbon neutrality, sustainable blueprints, human well-being, and one health for the planet, we hope this book will inspire interdisciplinary stakeholders to join hands and transfer knowledge to new generations for the sake of our sustainable future.
