The City of Taunton, MA (City) has undertaken a competitive procurement process to consider proposals for a private company to develop, design, permit, finance, construct and operate a Solid Waste Management Facility (SWMF), which may be sized up to 1800 tons per day (TPD), to serve both the City’s and region’s needs for long term solid waste management. A comprehensive Request for Qualifications and Proposals (RFQP) for the SWMF was issued in June 2008. The City initiated the procurement process because its current landfill is scheduled to reach capacity in 2013. The procurement process focused on conversion technologies capable of recovering materials and producing electricity or fuels, and maximizing diversion of waste from landfilling. Technologies considered included both traditional and emerging technologies; e.g., composting, co-composting, thermal gasification, aerobic and anaerobic digestion, hydrolysis and mechanical means of waste separation into useful products. Landfilling and traditional waste-to-energy technologies were not considered.

Taunton, Massachusetts (City) is a city of 55,000 people located in Southeast Massachusetts, approximately 35 miles from Boston. Currently it hosts a regional landfill that will reach capacity in 2013. Beginning in 2005, the City began the process of searching for a solid waste management technology to replace the landfill. The focus for the search has been on conversion technologies capable of recovering materials and producing electricity or fuels, and maximizing diversion of waste from landfilling. Technologies being considered include both traditional and emerging technologies; e.g., composting, co-composting, thermal gasification, aerobic and anaerobic digestion, hydrolysis and mechanical means of waste separation into useful products. Landfilling and traditional waste-to-energy technology are not being considered.

The article analyzes the features of municipal solid waste management in Tokyo. Special attention is paid to the analysis of trends in the volume of waste in the city of Tokyo over the past decades, as well as the reasons for the constant decline in these volumes. The article deals with the waste management activities of the Clean Authority of Tokyo, discusses the features of treatment of various types of waste, as well as the arrangement of the Tokyo city waste landfill. It was noted that the capital of Japan succeeded in creating an effective system for the disposal and recycling of municipal solid waste that can ensure the environmental safety of the city, as well as integrate waste into the country’s fuel and energy complex. An important feature of Japanese waste management companies is the desire not only to comply with official environmental standards, but also to adhere to their own standards, even more stringent. Based on an analysis of Japanese experience, the authors put forward proposals for optimizing the sphere of waste management in Russia. In particular, attention is drawn to the need to prevent an environmental catastrophe caused by a careless attitude to waste, improve the quality of life of citizens, prevent social unrest associated with environmental pollution, and also involve waste in the generation of electricity and heat. The authors note that as part of the “trash” reform, it is necessary to increase the environmental awareness of citizens, provide citizens with relevant and complete information about the industry, and create stricter environmental standards for waste to energy plants and other enterprises involved in waste management.

Municipal solid waste (MSW) is an energy source that should not go untapped or unutilized. The waste must be properly utilized through combustion, anaerobic digestion, and landfill gas acquisition, as it represents material and energy content. This will reduce the effects of global warming, which is as a result of high concentration of carbon dioxide, methane, and other greenhouse gases (GHGs), in the atmosphere. This chapter focuses on the technologies for solid waste management and the thermodynamics involved in the process for sustainable and cleaner energy. The equations presented represent the thermal efficiency, conversion efficiencies, as well as possible work that can be derived from a power plant utilizing MSW as fuel. It is important that countries in Sub-Saharan Africa vigorously pursue sustainable waste management technologies, especially recycling and landfilling, while exploring and investing in waste-to-energy technologies that will perform optimally using the composition of the waste in Sub-Saharan Africa in the design of the waste-to-energy technology.

In India, rate of waste generation varies from 0.12-0.60 kg/capita/day. This paper lists established solid waste management practices in India by providing the latest factual data from various reports and surveys being conducted in India in the period 2016 and beyond. This paper also gives an insight into some of the recent studies that have been in India related to solid waste and waste to energy technologies by describing their study area along with mentioning their critical observations.

The city of Mumbai (Bombay), India is facing a solid waste management crisis. The infrastructure has been unable to keep pace with economic development and population growth, resulting in insufficient collection of municipal solid waste (MSW) and over-burdened dumps. Improper disposal of solid wastes over several decades and open burning of garbage have led to serious environmental pollution and health problems. This study examined the solid waste management process in Mumbai and the potential for implementation of waste-to-energy facilities. Mumbai’s average per capita waste generation rate is 0.18 tonnes per person. Although the reported collection efficiency of MSW is 90%, almost half of the city’s 12 million people live in slums, some of which do not have access to solid waste services. The most pressing problem is the acute shortage of space for landfilling. When the present waste dumps were constructed they were at the outskirts of the city, but now they are surrounded by housing colonies, thus exposing millions of people to daily inconveniences such as odors, traffic congestion, and to more serious problems associated with air, land, and water pollution and the spread of diseases from rodents and mosquitoes. Mumbai is the financial center of India and has the highest potential for energy generation from the controlled combustion of solid wastes. The lower heating value of MSW is estimated in this study to be 9 MJ/kg, which is slightly lower than the average MSW combusted in the E.U. (10 MJ/kg). The land for the first WTE in Mumbai would be provided by the City and there is a market for the electricity generated by the WTE facility. The main problem to overcome is the source of capital since the present “tipping fees” are very low and inadequate to make the operation profitable and thus attract private investors. Therefore, the only hope is for the local government and one or more philanthropists in Mumbai to team up in financing the first WTE in India as a beacon that improves living conditions in Mumbai, reduces the City’s dependence on the import of fossil fuels, and lights the way for other cities in India to follow.
