Bioreactor landfills represent a new approach to landfill operations.
Geomembranes are synthetic membranes used to control fluid or gas migration.
Landfills that hold construction rubble like stones, wood, drywall, shingles, bricks, etc. offer substantially lower hazard potential
Some of the biggest concerns about sanitary landfills continue to be their ability to prevent contamination of the local environment
Leachate management is potentially the most significant, long-term, recurring cost for landfill care
A major historical problem with waste disposal, whether during the bad old days of primitive dumps or even in early landfill designs
Since leachate treatment and disposal can be a significant part of the operating cost for sanitary landfills
Leachate has long been an issue for garbage collection sites because of typically high levels of toxic contaminants
Choosing a liner means considering more than just how well it will handle the initial installation.
Secondary containment is the process of planning for eventual leaks, spills, and other forms of exposure.
Covers are widely used in landfill designs in order to control the production of leachate.
Leachate may exit the landfill mound as a highly concentrated mix of chemicals, organic matter, and heavy metals, but it doesn’t have to stay that way.
Leachate ponds often look deceptively simple. If they’re designed to hold relatively diluted leachate, they may even appear like a natural pond with healthy vegetation around the edges.
A complete leachate collection system begins under the landfill and extends from under the cells of trash.
While this thick runoff liquid is similar to many other byproducts from commercial and industrial processes, it’s also unique in some ways.
Depending on its size, the site plan, and the amount of annual rainfall, a landfill can generate hundreds of thousands of gallons of leachate water per year.
