2005: Middletown Landfill

In the fall of 2005, the Environmental Geochemistry Laboratory class (E&ES 281), at the request of the Jonah Center, conducted a preliminary study of methane production at the city landfill. Methane (CH4) is a greenhouse gas with about 20 times the heat trapping capability of CO2.  It lasts for about ten years in the atmosphere and decays to CO2. So there are both environmental and economic reasons to explore methane capture.

Students presented their findings at a public meeting at First Church of Christ Congregational on Dec. 20, with about sixty people in attendance. The study and landfill modeling yielded an estimate that 209 cubic feet of methane is released from the landfill per minute.

The Jonah Center sent the data from the Wesleyan study to the U.S. EPA Landfill Methane Outreach Program, which analyzed the results to determine whether it was economically feasible to capture and use the gas.  Assuming methane emissions of 150 cubic feet per minute (a reasonable estimate), flaring the gas to destroy the methane would reduce annual greenhouse gas emission equivalent to removing 2900 cars from the road.  Utilizing this same methane to fuel a 350 KW generator would be equivalent to reducing annual greenhouse gas emissions from an additional 2800 passenger vehicles or powering 280 homes for one year.  (Source, U.S. EPA Landfill Methane Outreach Program).

Endurant Energy LLC (Oak Terrace, IL) is the “developer;” Environmental Credit Corporation (State College, PA) will market the greenhouse gas reduction credits; William Charles Waste Companies (Rockford, IL) will determine the best location for the wells. Highland Power (Brockton, MA) will arrange for the local test well drilling. This initial phase of the project will determine the amount and quality of the gas emerging from the landfill. If there is sufficient gas, a 350 kW electricity generator will be installed to supply power to the grid.
