AEGL offers extensive experience and skill in drilling and well installation; pipeline installation; and the construction of gas compressor stations, flaring stations, and scrubbing and treatment stations. Additionally, AEGL’s expert understanding of and involvement in geosynthetics installation gives the company a unique perspective in the measures necessary to maximize LFG system effectiveness while protecting the installation’s other containment technologies.
THE IMPACT OF LFG SYSTEMS
As waste decomposes, gases such as methane, carbon dioxide, oxygen, nitrogen and other volatile organic compounds (VOCs) are produced. About 50% of the gases produced within municipal solid waste are methane, a greenhouse gas that can be harmful to human health and the environment. These gases are also potentially explosive. LFG systems relieve the pressure that these gases can cause inside the landfill, as well as prevent the gases from migrating laterally and threatening surrounding structures. Recovered LFG from landfills is either flared or developed as an alternative energy source. There are more than 500 landfill gas-to-energy projects active in the United States right now. The volume of gas contained in American landfills is equal to about 5% of the country’s annual natural gas usage.
