The government-accredited GA 2000 landfill gas analyzer was used to monitor the (methane (CH4) and carbon dioxide (CO2)) generated from subsurface of a landfill. Eighteen sample probes were constructed placed approximately 100 m apart on boundaries site. monitoring gases conducted over period two years, taking into consideration different seasons year. Results study show that as LFG migrates to...

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 ...

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...

This review evaluates current epidemiologic literature on health effects in relation to residence near landfill sites. Increases in risk of adverse health effects (low birth weight, birth defects, certain types of cancers) have been reported near individual landfill sites and in some multisite studies, and although biases and confounding factors cannot be excluded as explanations for these find...

Municipal solid waste (MSW) landfills are among the nation’s largest emitters of methane, a key greenhouse gas, and there is considerable interest in quantifying the surficial methane emissions from landfills. There are limitations in obtaining accurate emissions data by field measurements, and in characterizing an entire landfill with only a few such emissions measurements. This paper proposes...
