Recycling Landfills
Converting landfills into energy sources primarily involves capturing landfill gas (LFG), which is rich in methane, a potent greenhouse gas. Here’s a simplified overview of the process:
Gas Collection
Landfill gas (LFG), rich in methane, is collected using a series of wells and a blower/flare (or vacuum) system1.
Gas Processing
The collected gas is then processed to remove impurities and moisture to improve its quality2.
Energy Conversion
The processed gas can be used in several ways:
Electricity Generation: By burning the methane to power turbines or engines3.
Direct Use: As a direct source of heat or for industrial processes4.
Upgraded to Renewable Natural Gas (RNG): Purified further to meet natural gas pipeline quality standards and used as fuel for vehicles or injected into gas networks.
These methods help reduce greenhouse gas emissions, offset the use of non-renewable resources, and provide a renewable energy source that benefits the community and the environment.
