Question: Are there ways to reuse leachate produced in landfills?

Can leachate be reused?

While leachate recycle can reduce the strength of some MSW leachate, it still can pollute large amounts of groundwater. Leachate recycling is best used during the early stage in a fermentation/ leaching, wet-cell approach to MSW management.

What is done with leachate from landfills?

Leachate drains to the leachate collection system, where it is transferred to a central collection pump and piped to an onsite holding pond. If necessary, the leachate is transported to an approved offsite wastewater treatment plant for disposal.

How can we dispose leachate collected from a landfill?

There are many methods of leachate treatment [5] such as: Aerobic Biological Treatment such as aerated lagoons and activated sludge. Anaerobic Biological Treatment such as anaerobic lagoons, reactors. Physiochemical treatement such as air stripping, pH adjustment, chemical precipitation, oxidation, and reduction.

How is the environment protected from leachate in landfills now?

Composite liners requirements—include a flexible membrane (i.e., geo-membrane) overlaying two feet of compacted clay soil lining the bottom and sides of the landfill. They are used to protect groundwater and the underlying soil from leachate releases.

How long do landfill liners last?

A clay liner even a foot thick will fail within five years. That means that it’s pretty safe to assume that any landfill that began operating with unlined or clay lined cells is leaking toxic contaminants.

How is leachate handled at a typical municipal landfill?

Leachate can be controlled in lined landfills with leachate collection and storage systems. These systems typically include provisions for the drainage of leachate within the landfill and pumping the leachate to storage tanks. The stored leachate can then be trucked or pumped to a wastewater treatment plant.
