The notion of a lifestyle system leading to zero waste is obviously appealing, and a strategy of total reuse and recycling of: waste material is often advocated. However, there is a growing realization that the recycling process itself produces waste, and the environmental and economic cost of recycling and reusing certain materials invalidates the zero waste approach as a universally viable solution. Thus, solutions must be found to deal with the part of waste that it is not practicable to recycle or reuse. The energy content of municipal waste (whether raw or classified) is about 10MJ kg-1. If the total amount of waste material in any region is around 30 million tons per year or about 1000 kg/ s, the total energy is thus 10,000MJ /s = 10,000 MW. At an electricity generation efficiency of 20%, this could provide 2000 MW plus about 6000MWof district heating. This energy source is largely biomass, which is carbon dioxide neutral, and thus does not contribute to the total atmospheric greenhouse gases. The present work includes many aspects of municipal solid waste combustion, such as the effects of moisture, particle size and ash content effects on solid particle during process rates (moisture evaporation, volatile release, and char burning rate). The COMMENT code has developed to reveal much detailed information on the combustion processes. Through experimental and numerical investigations, the combustion process of simulated MSW in bed can be better understood and the experiment results can be used to amend the mathematics model and be consulted by the application in the project. The results from modeling can show the combustion process, and make us deeply know how the heat transfers in the fuel and gas yields from fuel. At the same time, the simulation can predict the maximum temperature of waste incineration and the trend concerning combustion.

The 4th International Conference on Innovation in Education, Science and Culture (ICIESC) 2022 shows up as a Mathematics and Natural Science, Material Science, Physics Education, Biology Education, Chemistry Education, Vocational Education, Applied Sciences-Computers, Multimedia Technology, Applied Mathematics, E-learning system, Applied Sciences-Information Technology, Applied Sciences-Engineering, Social Science and Humanities, Management Innovation and Heritage Culture research platform to gather presentations and discussions of recent achievements by leading researchers in academic research. With the number participants 260 participants, who came from the various national and international universities member, research institute, and academician. There are 181 papers passed through rigorous reviews process and accepted by the committee. All of papers reflect the conference scopes and become the latest trend. It has been our privilege to convene this conference. Our sincere thanks, to the conference organizing committee; to the Program Chairs for their wise advice and brilliant suggestion on organizing the technical program and to the Program Committee for their through and timely reviewing of the papers. Recognition should go to the Local Organizing Committee members who have all worked extremely hard for the details of important aspects of the conference programs and social activities. We welcome you to read this proceeding and hope the reader can find according to your interests and scientific field.

This book presents an overview of municipal solid waste recycling, and how it can be used to generate clean power, transport fuels that can substitute fossil fuels, and value-based chemicals with minimal environmental impact. It also explains how hazardous wastes and sewage sludge can be treated and disposed of without affecting human and environmental health. A full discussion of established thermal conversion technologies that generate heat, electricity, liquid fuels and useful chemicals from solid waste and supporting case studies describing global waste-to-energy plants in operation make this work highly suited to an introductory course on waste thermal conversion processes.

This book is written by Dr. Hui Zhou as a Ph.D. dissertation in Tsinghua University, China. It establishes the thermochemical characteristics of model compounds in combustible solid waste (CSW), and delineates the influence of different factors on the thermochemical characteristics and the influence interactions between model components have on the thermochemical characteristics. The works provide a theoretical basis for the clean and high-efficiency utilization of CSW as well as the basic knowledge for further understanding the thermochemical conversion mechanisms of complex fuels. Researchers and engineers in the field of thermal engineering and environmental engineering can benefit from the book.

The International Conference on Waste Management and the Environment is organised every two years by the Wessex Institute of Technology in collaboration with other institutions. This fifth conference follows the success of previous meetings held in C diz (2002), Rhodes (2004), Malta (2006) and Granada (2008). Waste Management is becoming one of the key problems of the modern world, an international issue that is intensified by the volume and complexity of domestic and industrial waste discarded by society. Unfortunately, many of the practices adopted in the past were aimed at short-term solutions without sufficient regard or knowledge for long-term implications on health, the environment or sustainability and this, in many cases, is leading to the need to take difficult and expensive remedial action. With our growing awareness of the detrimental environmental effects of current waste disposal, there is a significant onus of accountability for effective waste management. Better practice and safer solutions are required. Not only is there a need for more research on current disposal methods such as landfill, incineration, chemical and effluent treatment, but also on recycling, waste minimisation, clean technologies, waste monitoring, public and corporate awareness, and general education.

Air classified municipal solid waste (MSW) was fired in an atmospheric fluidized bed combustor at low excess air to simulate boiler conditions. The 7 ft2 combustor at Combustion Power Company's energy laboratory in Menlo Park, CA, incorporates water tubes for heat extraction and recycles elutriated particles to the bed. System operation was stable while firing processed MSW for the duration of a 300-h test. Low excess air, low exhaust gas emissions, and constant bed temperature demonstrated feasibility of steam generation from fluidized bed combustion of MSW. During the 300-h test, combustion efficiency averaged 99%. Excess air was typically 44% while an average bed temperature of 1400°F and an average superficial gas velocity of 4.6 fps were maintained. Typical exhaust emission levels were 30 ppM SO2, 160 ppM NO3 200 ppM CO, and 25 ppM hydrocarbons. No agglomeration of bed material or detrimental change in fluidization properties was experienced. A conceptual design study of a full scale plant to be located at Stanford University was based on process conditions from the 300-h test. The plant would produce 250,000 lb/hr steam at the maximum firing rate of 1000 tons per day (TPD) processed MSW. The average 800 TPD firing rate would utilize approximately 1200 TPD raw MSW from surrounding communities. The Stanford Solid Waste energy Program was aimed at development of a MSW-fired fluidized bed boiler and cogeneration plant to supply most of the energy needs of Stanford University.
