Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill. The testing methodology is used to determine if a waste is characteristically hazardous, i.e., classified as one of the "D" listed wastes by the U.S. Environmental ...
A shaking table laboratory test works to explore the strength characteristics at interfaces between different components of the landfill. Of primary concern is the contact between soil and landfill liner, as this is usually considered to be a weak point in the system. [4] A dynamic centrifuge test works to model the landfill in a scaled-down form.
A garbage landslide [1] is a man-made event that occurs when poorly managed garbage mounds at landfills collapse with similar energy to natural landslides.These kinds of slides can be catastrophic as they sometimes occur near communities of people, often being triggered by weather or human interaction.

The act established a framework for states to better control solid waste disposal and set minimum safety requirements for landfills. [4] In 1976 Congress determined that the provisions of SWDA were insufficient to properly manage the nation's waste and enacted the Resource Conservation and Recovery Act (RCRA). Congress passed additional major ...
The use of landfill gas is considered a green fuel source because it offsets the use of environmentally damaging fuels such as oil or natural gas, destroys the heat-trapping gas methane, and the gas is generated by deposits of waste that are already in place. 450 of the 2,300 landfills in the United States have operational landfill gas ...
There are different designs for landfills used for municipal solid waste or household waste, construction & demolition waste, and hazardous waste. According to an EPA report, the number of municipal solid waste landfills has gone down from 7924 in 1988 to 1754 in 2006. There were close to 1900 construction & demolition landfills in 1994.

For a long time, it was believed that paper is a relatively safe and environmentally friendly waste product, degrading quickly in landfills. Rathje showed, however, that paper is typically a bad degrader: newspapers dumped in landfills as much as over half a century ago, turn up again as fresh and as readable as the day they were issued.

Some types of Lithium-ion batteries such as NMC contain metals such as nickel, manganese and cobalt, which are toxic and can contaminate water supplies and ecosystems if they leach out of landfills. [17] Additionally, fires in landfills or battery-recycling facilities have been attributed to inappropriate disposal of lithium-ion batteries. [18]
