Landfill
site for the disposal of waste materials by burial
A landfill is a site for the disposal of waste materials, including municipal solid waste. It is the oldest and most common form of waste disposal, although the systematic burial of waste with daily, intermediate, and final covers only began in the 1940s. In the past, waste was simply left in piles or thrown into pits (known in archeology as middens).
Landfills take up significant amounts of land and pose environmental risks. 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 during an earthquake. Once full, the area over a landfill site may be reclaimed for other uses.
Both active and restored landfill sites can have significant environmental impacts which can persist for many years. These include the release of landfill gases that contribute to climate change and the discharge of liquid landfill leachates containing high concentrations of polluting materials.
Operations
Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to:
Confine waste to as small an area as possible
Compact waste to reduce volume
They can also cover the waste daily with layers of soil or other materials, such as wood chips and fine particles.
Begin with the source’s own compact description: “Landfill” is site for the disposal of waste materials by burial. The dossier treats that line as a proposition to test through Landfill, site and disposal, not as a finished interpretation.
Why this record matters
The phrase “site for the disposal of waste materials by burial” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 23, 2026. The linked authority identifier is Q152810. The Library of Congress control number is sh85117286. 1 of 1 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
