Motivation The other day I was waiting at the station for my train. Next to me a young lady was nonchalantly leaning against the wall. Suddenly, she took a cigarette pack out of her handbag, pulled out the last cigarette, put it between her lips, crushed the empty pack, threw it on the ground and hedonistically lit the cigarette. I thought to myself, "What a behavior?!". The nearest trashcan was just five meters away. So I bent down, took the crushed pack and gave it back to her, saying that she had lost it. She looked at me in a rather deranged way, but she said nothing and of waste to the trashcan. brought the piece Often people are not aware of the waste they produce. They get rid of it and that's it. As soon as the charming lady dropped the cigarette pack, the problem was solved for her. The pack was on the ground and it suddenly no longer belonged to her. It is taken for granted that somebody else will do the cleaning up. There is a saying that nature does not produce waste. For long as humans obtained the goods they needed from the ground where they lived, the waste that was produced could be handled by nature. This has drastically changed due to urbanization and waste produced by human activities has become a severe burden.

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

Increasing global consumerism and population has led to an increase in the levels of waste produced. Waste to energy (WTE) conversion technologies can be employed to convert residual wastes into clean energy, rather than sending these wastes directly to landfill. Waste to energy conversion technology explores the systems, technology and impacts of waste to energy conversion. Part one provides an introduction to WTE conversion and reviews the waste hierarchy and WTE systems options along with the corresponding environmental, regulatory and techno-economic issues facing this technology. Part two goes on to explore further specific aspects of WTE systems, engineering and technology and includes chapters on municipal solid waste (MSW) combustion plants and WTE systems for district heating. Finally, part three highlights pollution control systems for waste to energy technologies. Waste to energy conversion technology is a standard reference book for plant managers, building engineers and consultants requiring an understanding of WTE technologies, and researchers, scientists and academics interested in the field. Reviews the waste hierarchy and waste to energy systems options along with the environmental and social impact of WTE conversion plants Explores the engineering and technology behind WTE systems including considerations of municipal solid waste (MSW) its treatment, combustion and gasification Considers pollution control systems for WTE technologies including the transformation of wast combustion facilities from major polluters to pollution sinks

This volume in the Encyclopedia of Sustainability Science and Technology, Second edition, provides a comprehensive overview of complementary strategies for dealing with waste in and around urban areas: Waste-to-energy power plants (WTEs) and recycling. Chapters in this volume describe how these plants can be built within or near cities to transform the non-recycled residues of society into electricity and heat, and the recovery of metals using recycling technology and management techniques. The latter includes resource recovery from construction and demolition and electronic waste streams. With nearly one thousand WTE plants worldwide, waste incineration has become increasingly important as a means of closing the materials life- cycle loop. China leads in the beneficial use of these residues with about 30 new WTEs built in each of the last three years, and with plans for at least another 300 with one or more in each large city. In addition, increasing numbers of cement plants use "waste" materials as alternative fuels. Since currently all of these plants combust less than 20% of the available wastes, and the remainder ends up in landfills or dumps, this sector represents a huge market in the making.This comprehensive reference is suitable for readers just entering the field, but also offers new insights for advanced researchers, industry experts, and decision makers.

Material and Energy Recovery from Solid Waste for a Circular Economy describes solid waste to material and energy recovery to bridge the gap between theoretical possibilities and on-field criticalities. It deals with various resource recovery possibilities from numerous waste streams such as municipal solid, hazardous waste, human faecal sludge, construction and demolition waste, and electronic waste. The practical issues of resource recovery and possible remedies derived through onsite practice and experience are incorporated. It includes real-life feasibility analysis and implementation of waste-to-energy systems supported by case studies. Features: Provides comprehensive discussion on both energy and material recovery Addresses the missing linkage between the techno-commercial feasibility of existing systems and environmental impact Discusses techno-commercial feasibility and environmental impacts Offers balance between theoretical knowledge sharing and practical execution-related issues Includes case study, LCA, and technical feasibility chapters This book is aimed at graduate students and researchers in environmental, civil, and chemical engineering.
