The term landfill is usually shorthand for a municipal landfill or sanitary landfill. These facilities were first introduced early in the 20th century, but gained wide use in the 1960s and 1970s, in an effort to eliminate open dumps and other "unsanitary" waste disposal practices. The sanitary landfill is an engineered facility that separates ...
Landfills are the third-largest source of methane emissions in the United States, with municipal solid waste landfills representing 95 percent of this fraction. [15] [16] In the U.S., the number of landfill gas projects increased from 399 in 2005, to 594 in 2012 [17] according to the Environmental Protection Agency.

A modern sanitary landfill is not a dump; it is an engineered facility used for disposing of solid wastes on land without creating nuisances or hazards to public health or safety, such as the problems of insects and the contamination of groundwater.
Sanitation technologies may involve centralized civil engineering structures like sewer systems, sewage treatment, surface runoff treatment and solid waste landfills. These structures are designed to treat wastewater and municipal solid waste. Sanitation technologies may also take the form of relatively simple onsite sanitation systems.
Some landfill sites are used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling. Unless they are stabilized, landfills may undergo severe shaking or soil liquefaction of the ground during an earthquake.
A sanitary landfill is where waste is disposed of in thin layers little by little; each layer is covered and compacted with soil to prevent foul odors and wind blown litter. [5] This method prevents the creation of safety and public health hazards; this landfill has four requirements before it is built.
