Gasification of Waste Materials: Technologies for Generating Energy, Gas and Chemicals from MSW, Biomass, Non-recycled Plastics, Sludges and Wet Solid Wastes explores the most recent gasification technologies developing worldwide to convert waste solids to energy and synthesis gas and chemical products. The authors examine the thermodynamic aspects, accepted reaction mechanisms and kinetic constraints of using municipal solid waste (MSW), biomass, non-recycled plastics (NRP), sludges and wet solid wastes as feedstock. They identify the distinctions between pyrolysis, gasification, plasma, hydrothermal gasification, and supercritical systems. A comprehensive summary of laboratory and demonstration activities is presented, as well as field scale systems that have been in operation using solid waste streams as input, highlighting their areas of disconnect and alignment. The book also provides a summary of information on emissions from the stack, comparing them with other thermal conversion systems using similar feedstock. It then goes on to assess the areas that must be improved to ensure gasification systems become as successful as combustion systems operating on waste streams, ranging from feedstock processing to gasifier output gas clean-up, downstream system requirements and corrosion. The economics and future projections for waste gasification systems are also discussed. For its consolidation of the current technical knowledge, this text is recommended for engineering researchers, graduate students, industry professionals, municipal engineers and decision makers when planning, designing and deploying waste to energy projects, especially those using MSW as feedstock. - Provides field demonstrations of large scale systems, their results and the challenges that need to be overcome when developing commercial applications and possible solutions - Presents the most recent technologies in lab and demonstration scale - Examines the critical development needs and real life challenges for the deployment of waste to energy technologies - Provides information on the economics and sustainability of these technologies, as well as their future perspectives

This title includes a number of Open Access chapters. Increasing attention is being paid to the valorization of solid wastes—converting them into energy or other useful products. This book describes recent research into methodologies and technologies for managing various forms of solid waste, while at the same time generating energy and revenue with less impact on the environment. Topics include combustion, gasification, pyrolysis, and hydrothermal carbonization. The transition from a fossil fuel-based economy to a more sustainable economy will require a solid foundation of ongoing scientific research. The editor of this compendium, a well-respected researcher in the field, has selected studies that help to build that foundation.

Most coveted energy forms nowadays are gas in nature and electricity due to their environmental cleanness and convenience. Recently, gasification market trend is starting to switch to low-grade feedstock such as biomass, wastes, and low-rank coal that are still not properly utilized. In this sense, the most promising area of development in gasification field lies in low-grade feedstock that should be converted to more user-friendly gas or electricity form in utilization. This book tried to shed light on the works on gasification from many parts of the world and thus can feel the technology status and the areas of interest regarding gasification for low-grade feedstock.
