Choosing Landfill Gas and Leachate Collection Systems
Everything from the exact number of wells installed on a landfill cell, to the type of collection system, affects the selection of a cover material.
Well Spacing for Adequate Control and Efficient Gas Capture
Most of the factors that control the final gas production rate of any particular landfill cell, such as soil compaction or liner selection, are chosen long before it’s closed.
Site Preparation Tips for Landfills Designed for Gas Production
Designing a landfill cell with gas collection in mind from the start, is the best way to maximize production over time.
How Liners Play an Essential Role in Landfill Gas Collection
It’s easy to assume that all gas issues in a landfill cell are handled by the cover and that the liner only manages leachate and other liquids.
Capping Landfills with the Right Cover Material for Gas Collection
Gas release may begin as soon as the first layer of waste is added to the cell, but these early discharges of carbon dioxide and methane are usually permitted as long as they’re limited.
Condensate and Leachate: Inevitable Byproducts of Gas Production
While landfill systems designed for gas collection and control may be primarily focused on gases, liquids also play important roles and can’t be overlooked.
What’s in Landfill Gas?
Landfill gas is often mistaken for being a single type of gas due to being referred to by the LFG term.
Why Collect and Contain Landfill Gas?
All waste eventually breaks down, even if it takes thousands of years.
Handling the Tailings and Residues Left After Ore Processing
Ore processing may be an environmentally friendly and energy efficient way to recover metals that would otherwise be lost.
Pregnant, Processing, and Barren Ponds
Each heap leaching facility has its own system for dealing with the leachate that flows from the pad.
Lining Pregnant and Processing Ponds the Right Way
Each heap leaching facility is unique in its design and the process it uses for ore recovery.
Protecting the Environment from Ore and Mineral Processing
Despite the risks that come with using chemicals to separate ore from rock, heap leaching is one of the safest and least damaging methods to use.
The Power of Solutions and Lixiviants for Separating Ore from Waste
Heap leaching is just the first stage in the ore recovery process.
How Do Processing Ponds Work as Part of the Mining Cycle?
Processing ponds are far from an isolated system on their own.
Heap Leaching and More for Ore Processing
There are many methods for extracting ore from the raw rock and minerals they’re often mixed in with.
Building a Swimming Pond the Right Way
Natural swimming pools are among the trendiest types of residential ponds being built today.
Designing a Residential Pond for Fish
Residential ponds may have a primary use for stormwater detention or wetland conservation, but fish often become a secondary part of the design.
Pre-formed vs Custom Pond Liners for Recreational Ponds
Backyard pond design is particularly challenging for homeowners that need to work on a limited budget.
Which Pond Liners are Right for Residential Designs?
Even a little backyard water feature benefits from a real pond liner.
Common Misconceptions About Liners for Residential Ponds
Pond liners are often mistaken as a material only used on large, professional, or public ponds.
Why Natural Liners and Clay Soils Aren’t Enough for Recreational Ponds
There are plenty of pond building guides, especially older published sources, that claim flexible pond liners are unnecessary.
The Main Types of Backyard and Residential Ponds
Residential ponds may come in many different designs, but they all fall into a few different categories.
Interlift Liners or Single Liner Systems: Choosing the Right Design
For hundreds of years, heap leach pads were simple constructions of graded and berm soil with ore piled directly on top of the ground.
