DMASWA Landfill Reduces Greenhouse Gas Emissions by 65%

The Dubuque Metropolitan Area Solid Waste Agency Landfill (Agency), via its participation in the Iowa Department of Natural Resources (INDR) Environmental Management System (EMS) program, set a goal in 2016 to reduce greenhouse gas emissions by 2,000 tons of carbon dioxide equivalents (CO2e). To achieve the EMS goal the Agency sought to develop a project to utilize landfill gas (primarily methane) in a beneficial manner. In March 2020, an agreement was reached with Dubuque Gas Producers to develop a Renewable Natural Gas (RNG) project on site to capture the gas, treat the gas to meet all pipeline standards and then deliver it to a Black Hills pipeline.

The Agency’s reported CO2e emissions were 39,424 tons in 2016. With the RNG plant coming online in 2021, the Agency’s reported CO2e emissions were reduced to 13,708.8 tons, a reduction of 25,715.2 tons or 65% from 2016 base year.
