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.

About the Authors

Simona Ciuta

Dr. Simona Ciuta was born in Bucharest, Romania. She received her B.S. in Environmental Engineering from Politehnica University of Bucharest. Dr. Ciuta developed her bachelor's thesis at the University of Trento, Italy after being awarded an Erasmus Scholarship. She obtained a Masters Degree in Environmental Management and a Ph.D. in Power Engineering from Politehnica University of Bucharest, Romania. During her Ph.D. she was invited at University of Trento, Italy for research stages to further develop her thesis. Currently, Dr. Ciuta works as a Post-Doctoral Research Associate for the Combustion and Catalysis Laboratory in the Department of Chemical Engineering at City College of New York (CCNY). Prior to CCNY, she was an Assistant Professor in the Power Engineering Department at Politehnica University of Bucharest. She worked as Research Assistant on several European Union funded projects during her Ph.D, in particular in the field of biomass conversion into energy, waste characterization and advanced thermal processes. Dr. Ciuta`s research focuses on waste materials conversion into energy, waste management, thermal processes such as gasification and pyrolysis. She published 12 journal papers, 2 book chapters, and approximately 30 conference proceedings papers in the field. Dr. Ciuta developed a one of a kind intra-particle gas sampling technique that provides significant insight into fundamental reaction sequences happening during thermal decomposition of waste materials.

Marco J. Castaldi

Marco Castaldi was born in New York City and received his B.S. ChE (Magna cum Laude) from Manhattan College. His Ph.D. is in Chemical Engineering from UCLA and he has minors in Advanced Theoretical Physics and Astrophysics. Prior to joining CCNY he was Associate Professor at Columbia University’s Earth & Environmental Engineering Department. Professor Castaldi has approximately 90 peer-reviewed research articles, 40 peer-reviewed conference papers, 3 book chapters and 11 patents in the fields of catalysis, combustion and gasification. Some of his research findings have been covered by The New York Times, The Observer, CNN, and other trade publications. In addition, he was the Editor of the North American Waste to Energy Conference (NAWTEC) Series (ISBN: 978-0-7918-4393-2), Co-Editor of the Waste to Energy text published by Woodhead Publishing, Editorial Board Member of Waste and Biomass Valorization published through Springer (ISSN: 1877-2641) and Catalysts (ISSN 2073-4344). Prior to his academic career in Professor Castaldi worked first as Manager of Fuel Processor Component Development for Precision Combustion Inc. in New Haven, CT overseeing projects totaling $5 MM. Professor Castaldi is Past Chair of the Materials and Energy Recovery Division of ASME, Past Chair of the Research and New Technology Council of AIChE and recent Past-Chair of the North American Catalysis Society’s New York Metropolitan Section. He is a consultant to several companies including WasteManagement and AECOM. Dr. Castaldi is the Director of the Waste-to-Energy Research and Technology Council (WTERT) in the United States, an international organization that supports several students and post doctoral researchers; also, his group is recognized by the American Society of Mechanical Engineers as the foremost research group on chemical kinetics of converting wastes to energy. Dr. Castaldi’s research will lead to the development of advanced waste-to-energy processes and in particular the high-efficiency recovery of energy from biomass processes using catalysis. Understanding the fundamental reaction sequences and their associated kinetic parameters is the sure way to provide the requisite capability to explore and develop new technologies while improving existing ones for converting “waste” resources into renewable energy. Currently Dr. Castaldi has established the Earth Engineering Center at City College, City University of New York. The goal of EEC|CCNY is to bring to bear rigorous engineering solutions that enable responsible use of energy and materials for the advancement of society. Through industry collaborations and research sponsorship EEC|CCNY develops novel solutions to some of the world’s most pressing problems.
