<p>Waste is discarded materials of no further use to the owners and the pattern of its generation is a function of the level of urbanization, industrialization and economic status of society. The most convenient strategy of solid waste disposal is landfill ...

Performance of four different municipal solid waste landfill liner systems, i.e., Subtitle D composite liner system, composite liner system with a geosynthetic clay liner (GCL) instead of low permeability compacted soil, Wisconsin NR500 liner system, and proposed ...

Many states allow construction of landfills over previously mined areas. However, mitigation of the underground mines by filling or removal is often required prior to landfill construction. A settlement analysis for the proposed vertical expansion of a residual ...

Understanding and prediction of the spreading of acid mine drainage (AMD) in groundwater and the breakthrough of acidity and heavy metals downstream of waste deposits are important for risk assessments of mining sites.

In this paper, the problem of nitrogen will be discussed in detail according to the separate problem fields based on the authors' experience, as well as on the basis of a review of the relevant literature. Furthermore, possible solutions will be proposed and ...

Almost 60% of waste disposal sites in Brazil are open dumps with no infrastructure for environmental protection. It is usual to find uncovered waste. The rainwater runs off over the uncovered top of the waste dump. This water may contaminate the soil. This ...

This paper describes characteristics of tailings ponds, highlighting situations and events that weaken such facilities, and provides a method for calculating the destructive capacity of tailings flow slides from failed facilities.

<p>The U.S. Environmental Protection Agency has collected and reported data on the generation and disposal of waste in the United States for more than 30 years. We use the information to measure the success of waste reduction and recycling programs across ...

This study describes a way of studying landfill microbial communities using landfill gas and landfill gascondensate, which allows collecting many numbers of samples without disrupting the waste. Comparisons between landfill waste and landfill gas microbial ...

In this paper is shown that former and present landfill techniques at the Filborna plant in Helsingborg, South Sweden are compared with respect to impacts on the environment
