The Hydrologic Evaluation of Landfill Performance (HELP) model is a quasi-two-dimensional hydrologic numerical model for conducting water balance analysis of landfills, cover systems, and other solid waste containment facilities; it was developed for the United States Environmental Protection Agency.
The Olusosun nigerian dumpsite is a 100-acre [1] dump in Lagos, Lagos State, Nigeria. [2] It is the largest in Africa, and one of the largest in the world. The site receives up to 10,000 tons of rubbish each day. Waste from around 500 container ships is also delivered to the site, adding a substantial portion of electronic waste. Some of this ...
Landfill operation in Hawaii. The area being filled is a single, well-defined "cell" and a protective landfill liner is in place (exposed on the left) to prevent contamination by leachates migrating downward through the underlying geological formation. Landfills have the potential to cause a number of issues.
In 2011, GMI awarded a grant to the LAWMA for studies evaluating the feasibility of capturing landfill gas from the Abule Egba and Solous Landfills. Based on their findings, LAWMA developed a landfill gas energy project to the local residents which serve as a reliable source of electricity. [10] 15 September 2020, LAWMA launched the LAWMA Academy.
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 ...
All landfills sites in South Africa are required by law to have a buffer zone between the active landfill and adjacent communities. [3] The Buffelsdraai buffer zone would be a minimum of 800 m wide and 787 ha in extent and would shield the neighbouring communities, namely Buffelsdraai and Osindisweni, from the impacts of the landfill.

Landfill mining and reclamation (LFMR) is a process which excavates and processes solid wastes which have previously been landfilled. [1] The process aims to reduce the amount of landfill mass encapsulated within the closed landfill and/or temporarily remove hazardous material to allow protective measures to be taken before the landfill mass is replaced.
A landfill liner, or composite liner, is intended to be a low permeable barrier, which is laid down under engineered landfill sites. Until it deteriorates, the liner retards migration of leachate , and its toxic constituents, into underlying aquifers or nearby rivers from causing potentially irreversible contamination of the local waterway and ...
