Improving municipal solid waste management in India
Human activities create waste, and the
ways that waste is handled, stored, collected, and disposed
of can pose risks to the environment and to public health.
Solid waste management (SWM) includes all activities that
seek to minimize health, environmental, and aesthetic
impacts of solid waste. In urban areas, especially in the
rapidly urbanizing cities of the developing world, problems
and issues of municipal solid waste management (MSWM) are of
immediate importance. This book addresses the problem by
focusing on India. A country such as India, with its high
economic growth and rapid urbanization, requires immediate
solutions to the problems related to mismanagement of urban
waste. City managers are actively trying to understand the
problem and are seeking effective ways of intervening. They
realize that such interventions are essential to improving
the quality of their cities and to reducing adverse health
and environmental impacts. For cities to be sustainable and
to continue their economic development, they must be clean
and healthy. They need to improve their SWM systems by
adopting good collection coverage, appropriate transfer
methods, and healthy disposal practices.

Nuclear waste management in Canada : critical issues, critical perspectives
\"What do frequently used terms such as safety, risk, and acceptability really mean? How and why did the public consultation process in Canada fail to address ethical and social issues? What is the significance and potential of a public consultation process that involves diverse interests, epistemologies, and actors, including Aboriginal peoples?\"-- Publisher.

An overview of the environmental pollution and health effects associated with waste landfilling and open dumping
Landfilling is one of the most common waste management methods employed in all countries alike, irrespective of their developmental status. The most commonly used types of landfills are (a) municipal solid waste landfill, (b) industrial waste landfill, and (c) hazardous waste landfill. There is, also, an emerging landfill type called “green waste landfill” that is, occasionally, being used. Most landfills, including those discussed in this review article, are controlled and engineered establishments, wherein the waste ought to abide with certain regulations regarding their quality and quantity. However, illegal and uncontrolled “landfills” (mostly known as open dumpsites) are, unfortunately, prevalent in many developing countries. Due to the widespread use of landfilling, even as of today, it is imperative to examine any environmental- and/or health-related issues that have emerged. The present study seeks to determine the environmental pollution and health effects associated with waste landfilling by adopting a desk review design. It is revealed that landfilling is associated with various environmental pollution problems, namely, (a) underground water pollution due to the leaching of organic, inorganic, and various other substances of concern (SoC) contained in the waste, (b) air pollution due to suspension of particles, (c) odor pollution from the deposition of municipal solid waste (MSW), and (d) even marine pollution from any potential run-offs. Furthermore, health impacts may occur through the pollution of the underground water and the emissions of gases, leading to carcinogenic and non-carcinogenic effects of the exposed population living in their vicinity.

Municipal solid waste management and landfilling technologies: a review
The USA, China and India are the top three producers of municipal solid waste. The composition of solid wastes varies with income: low-to-middle-income population generates mainly organic wastes, whereas high-income population produces more waste paper, metals and glasses. Management of municipal solid waste includes recycling, incineration, waste-to-energy conversion, composting or landfilling. Landfilling for solid waste disposal is preferred in many municipalities globally. Landfill sites act as ecological reactors where wastes undergo physical, chemical and biological transformations. Hence, critical factors for sustainable landfilling are landfill liners, the thickness of the soil cover, leachate collection, landfill gas recovery and flaring facilities. Here, we review the impact of landfill conditions such as construction, geometry, weather, temperature, moisture, pH, biodegradable matter and hydrogeological parameters on the generation of landfill gases and leachate. Bioreactor landfills appear as the next-generation sanitary landfills, because they augment solid waste stabilization in a time-efficient manner, as a result of controlled recirculation of leachate and gases. We discuss volume reduction, resource recovery, valorization of dumped wastes, environmental protection and site reclamation toward urban development. We present the classifications and engineered iterations of landfills, operations, mechanisms and mining.
