The Basics of Heap Leach Pad Operation
Heap leaching is a unique technique, but it’s based on some fairly basic concepts.
Why Rain Covers Can’t Replace the Need for Landfill Liners
All landfills need impermeable cover materials eventually when they shut down.
Tips on Choosing a High Quality Landfill Cover
There’s more to shopping for a landfill cover than just material selection.
What Materials Work Best for Landfill Rain Covers?
It’s not enough to avoid general purpose tarps and stick to geomembranes to find the right landfill cover.
Why is Storm Water Containment So Challenging at a Landfill?
A lot of attention is paid to leachate control and management at a landfill, and for good reason. Each cell can produce thousands to millions of gallons of wastewater.
Repurposed Tarps vs Geomembrane Rain Covers
The term, tarp, is commonly used casually in the landfill management business to refer to rain covers used for temporary and daily cover.
Temporary Rain Covers vs Permanent Closure Covers
Landfills must be capped and closed when they’ve reached capacity and can no longer accept more waste.
How Landfill Cell Design Limits Leachate
Despite the risks of leachate, it’s an unavoidable part of any landfill. Storing any kind of waste will result in leachate creation, even if there’s no organic waste mixed in to release water as it decomposes.
The Problem of Leachate and Storm Water at the Modern Landfill
Water, in general, is a tricky thing to handle at a waste facility. Most municipal waste facilities known as landfills accept only dry waste products, but there’s still quite a bit of water in most “dry” waste streams.
How Long Can Liners for Leachate Ponds Last?
Choosing a liner means considering more than just how well it will handle the initial installation.
Designing the Leachate Pond with Secondary Containment in Mind
Secondary containment is the process of planning for eventual leaks, spills, and other forms of exposure.
Why Cover a Landfill Leachate Pond?
Covers are widely used in landfill designs in order to control the production of leachate.
Treatment Options for Improving Leachate from Landfills
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.
Why Lining is Essential for Leachate Ponds
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.
Building a Complete Leachate Collection System
A complete leachate collection system begins under the landfill and extends from under the cells of trash.
How is Landfill Leachate Formed?
While this thick runoff liquid is similar to many other byproducts from commercial and industrial processes, it’s also unique in some ways.
What are Landfill Leachate Ponds?
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.
Secondary Containment and Leak Detection for Landfill Cells
Secondary containment is a major challenge for every outdoor waste storage project, but it’s particularly hard for landfill operators.
Soil Caps vs Geomembrane Caps for Landfill Cells
It’s often a misconception that landfill cell designers choose between soil or impermeable covers when creating a cap for a closed unit.
Designing Multi-Layered Liner Systems for Landfills
Lining a landfill is quite possible, but it is a bigger challenge than some operators first assume.
Open Dumps vs Sealed and Capped Landfill Cells
For centuries, solid waste disposal was informal and largely consisted of burning and burying trash in small amounts near a home or business.
Why Methane Makes Landfill Capping So Tricky
The lined and capped design of a modern landfill cell may make it seem like the perfect way to contain solid waste, regardless of its composition or age.
Why Landfills Liners and Caps Go Hand in Hand
Landfill cell design requires more than just correct volume calculations and properly sloped berms.
