There has been a significant increase in municipal solid waste (MSW) generation in India during the last few decades and its management has become a major issue because the poor waste management practices affect the health and amenity of the cities. In the present study, various physico-chemical parameters of the MSW were analyzed to characterize the waste dumped at Gazipur landfill site in Del...

As a developing country the protection of groundwater resources is extremely important in India. Landfills are a major source of water pollution. The filling for the disposal site in Ahmedabad, occurs at a distance of about 50 meters from Ahmedabad plant water intake. In addition, there are several holes are near the tip, which is used for drinking and domestic use. A survey of the composition ...

Problem statement: There is growing concern about landfill adverse health effects from exposure to landfill emissions. Approach: Airborne dust samples from houses near Jeleeb AlShuyoukh landfill and control residences were analyzed for molds and bacteria and Volatile Organic Compounds (VOCs) each month for one year. Results: The number of mold species was greater in the residences close to Jele...

Introduction Modern landfills are highly engineered containment systems, designed to minimize the impact of solid waste (refuse, trash, and garbage) on the environment and human health. In modern landfills, the waste is contained by a liner system. The primary purpose of the liner system is to isolate the landfill contents from the environment and, therefore, to protect the soil and ground wate...

In Hong Kong, landfill dumping has been a main approach for municipal solid wastes disposal and will be continued in the near future. However, gaseous emission from municipal waste may causes offensive odours and disturbs the neighbours around landfill sites. Usually there are not enough buffer zones between landfill sites and the nearest sensitive receptors due to a land restriction in Hong Ko...

The technology used in landfill covers is changing, and an alternative cover called the evapotranspiration (ET) landfill cover is coming into use. Important design requirements are prescribed by Federal rules and regulations for conventional landfill covers but not for ET landfill covers. There is no accepted hydrologic model for ET landfill cover design. This paper describes ET cover requireme...

This paper begins by providing an outline of various waste stabilisation techniques on which the concept of bioreactor or process-based landfills is based, followed by an overview of the research and development of this alternative landfill approach. The paper then presents a summary of the Australian experience. It also reports on the current state of bioreactor landfills and discusses the dif...

In this research, Chapter 1 is dedicated to analytical evaluation of landfill gas recovery. The majority of the world's municipal solid waste in is still going to the landfills, US being no exception. According to BioCycle and Earth Engineering Center, about 270 million tons of waste are landfilled annually in US. Anaerobic degradation, a naturally occurring process on the landfills, generates ...

Carbon dioxide, methane and nitrous oxide are the major Greenhouse Gases (GHG’s), which emit from landfill areas and contribute significantly to global warming. Moreover, that the global warming potential of methane is 21 times higher than that of carbon dioxide and it has highest generation (60%) than other gases. Therefore, there is immense concern for its abatement or utilization from landfi...

Recently, roofed landfills have been gaining popularity in Japan. Roofed landfills have several advantages over non-roofed landfills such as eliminating the visibility of waste and reducing the spread of offensive odours. This study examined the moisture balance and aeration conditions, which promote waste stabilisation, in a roofed landfill that included organic waste such as food waste. Moist...
