Sulfur, Energy, and Environment is a guide to the properties of sulfur; its three important compounds; and a review of the production, use, and recovery of sulfur in relation to energy production and environmental protection. After a brief introduction to the history of sulfur, the chemical properties of the element and some important compounds are reviewed, using common analytical methods. Sulfur is a strategic chemical in many modern applications and may make headway into high-volume non-chemical uses as it is being modified according to our changing technology and needs. The sources of sulfur and where it frequently occurs is explained. This discussion is followed by citing reviews of the four most important cycles, that is, the global sulfur cycle, hydrosphere, atmospheric sulfur budget, and the anthropogenic sulfur cycle. Sulfur production methods, coal combustion chemistry, and flue gas desulfurization are then described. The many uses of sulfur are described, including in medicine, agriculture, chemical industry, and the plastic industry. However, throughout the production of sulfur, problems affecting the environment occur, so environmental control and legislation are also discussed. Finally, the trends of sulfur research, production, use and recovery, role of chemistry, and the future overall area where science, energy, chemistry, and the environment exist together are presented. Chemists and chemistry students, industrialists, and environmental planners will find this guide to sulfur helpful. Lecturers in chemistry and researchers in the many fields of application of sulfur will likewise benefit from it.

This second edition is fully updated with new material to create a comprehensive and accessible reference book: New chapters on sulfur removal via bioelectrochemical systems, use of sulfate radicals in advanced oxidation processes and sulfur nanoparticle biosynthesis. New sections on: sulfur cycle chemistry and microbiology; sulfate removal vs. recovery of resources from sulfate-rich wastewaters; microaeration for biogas desulfurisation; biological treatment of gypsum and sulfur-rich solid waste; up-to-date process control for treatment of sulfur-rich waste streams. New case studies with emphasis on practices for sewer and steel corrosion control, odour mitigation, autotrophic denitrification and bioremediation of acid mine polluted sites in both developed and developing countries have been included. Novel concepts of environmental technologies to treat sulfur pollution of wastewater, off-gases, solid waste, soils and sediments are presented. Up-to-date research findings and innovative technologies for recovering resources, i.e. metals, fertiliser, biofuels and irrigation water, from sulfur polluted waste are provided. This book may serve both as an advanced textbook for undergraduate and graduate students majoring in environmental sciences, technology or engineering as well as a handbook for tertiary educators, researchers, professionals and policymakers who conduct research and practices in the sulfur related fields. It is essential reading for consulting companies when dealing with sulfur related environmental (bio)technologies.

In the context of wastewater treatment, Bioelectrochemical Systems (BESs) have gained considerable interest in the past few years, and several BES processes are on the brink of application to this area. This book, written by a large number of world experts in the different sub-topics, describes the different aspects and processes relevant to their development. Bioelectrochemical Systems (BESs) use micro-organisms to catalyze an oxidation and/or reduction reaction at an anodic and cathodic electrode respectively. Briefly, at an anode oxidation of organic and inorganic electron donors can occur. Prime examples of such electron donors are waste organics and sulfides. At the cathode, an electron acceptor such as oxygen or nitrate can be reduced. The anode and the cathode are connected through an electrical circuit. If electrical power is harvested from this circuit, the system is called a Microbial Fuel Cell; if electrical power is invested, the system is called a Microbial Electrolysis Cell. The overall framework of bio-energy and bio-fuels is discussed. A number of chapters discuss the basics – microbiology, microbial ecology, electrochemistry, technology and materials development. The book continues by highlighting the plurality of processes based on BES technology already in existence, going from wastewater based reactors to sediment based bio-batteries. The integration of BESs into existing water or process lines is discussed. Finally, an outlook is provided of how BES will fit within the emerging biorefinery area.

This is a compilation of topics that are at the forefront of many technical advances and practices in air and water control. These include air pollution control, water pollution control, water treatment, wastewater treatment, industrial waste treatment and small scale wastewater treatment.

Handbook of Green Economics reveals the breadth and depth of advanced research on sustainability and growth, also identifying opportunities for future developments. Through its multidimensional examination, it demonstrates how overarching concepts, such as green growth, low carbon economy, circular economy and others work together. Some chapters reflect on different discourses on the green economy, including pro-growth perspectives and transformative approaches that entail de-growth. Others argue that green policies can spark economic innovation, particularly in developing and emerging market economies. Part literature summary, part analysis and part argument, this book shows how the right conditions can stimulate economic growth while achieving environmental sustainability. This book will be a valuable resource for graduate students and academic researchers whose focus is on the green economy. With an increasing interest in the topic among researchers and policymakers, users will find different theoretical perspectives and explore policy implications in this growing subject area.
