Landfill Gas Recovery

Landfill gas (LFG) is the natural by-product of the decomposition of solid waste in landfills and is composed primarily of carbon dioxide and methane. Instead of allowing LFG to escape into the air, it can be captured, converted, and used as an energy source. Using LFG helps to reduce odors and other hazards associated with LFG emissions, and it helps businesses, states, energy providers, and communities protect the environment and build a sustainable future.

WESTON provides design, construction, and O&M services for active and closed landfills, including operating and maintaining cells and caps, gas collection and control systems, landfill gas-to-energy systems, and the environmental monitoring services required for compliance with state and/or local regulations, such as groundwater or methane monitoring. A leader in applying innovative technology-based solutions to fit our clients’ needs, WESTON has received external recognition for the wireless remote monitoring and communications systems we developed to replace traditional, paper-based monitoring of environmental and meteorological data.

Project examples:

City of Macon, GA - Provided all services to design and construct the landfill gas collection and control system (GCCS) to meet Title V requirements and provide an alternative fuel to an end-user. Use of an innovative drilling technology and remote monitoring technology earned WESTON and the City of Macon the 2006 Innovation Award from the GA Chapter of SWANA. The GCCS removes over 1.2 million cubic feet per day of LFG that supplies ~14 MMBtu per day of the LFG to fire the brick kilns of an off-site end-user adjacent to the landfill.

Fulton County, GA - Performed LFG collection system design and construction. The initial phase of the project included the design and construction of 39 active gas extraction wells, initially routed to a utility gas flare. A subsequent utilization project will enable an industrial client to offset $2M of fuel oil with gas collected from the landfill; WESTON is now pursuing VERs (carbon credits) for the client.
