    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.

  3. Leachate - Wikipedia

    en.wikipedia.org/wiki/Leachate

    As liquid enters the landfill cell, it moves down the filter, passes through the pipe network, and rests in the sump. As collection systems are planned, the number, location, and size of the sumps are vital to an efficient operation. When designing sumps, the amount of leachate and liquid expected is the foremost concern.

  4. Mechanical biological treatment - Wikipedia

    Residual unusable materials prepared for their final safe treatment (e.g., incineration or gasification) and/or landfill; Further advantages: Small fraction of inert residual waste; Reduction of the waste volume to be deposited to at least a half (density > 1.3 t/m 3), thus the lifetime of the landfill is at least twice as long as usual

  7. Bioreactor landfill - Wikipedia

    en.wikipedia.org/wiki/Bioreactor_landfill

    Landfills are the primary method of waste disposal in many parts of the world, including United States and Canada.Bioreactor landfills are expected to reduce the amount of and costs associated with management of leachate, to increase the rate of production of methane (natural gas) for commercial purposes and reduce the amount of land required for land-fills.

  8. Locally unwanted land use - Wikipedia

    en.wikipedia.org/wiki/Locally_unwanted_land_use

    What makes a LULU such as this unique is that they cause displacement, whereas a landfill, dump, roads, or prisons simply discourage home-buyers from entering the area and keep home prices low. High-end health food stores such as Whole Foods causes displacement by attracting high-earning home buyers into the area, causing rents and home prices ...
