A patented technology to convert landfill gas to ethanol has been garnering attention, most notably from the City of Cedar Rapids, Iowa. Plans are in the works to contract an independent engineering firm to conduct a technical, economic feasibility study for the technology at one of the city’s landfill sites.
The process was developed and patented by Bio-Thermal-Energy Inc. of Cedar Rapids, specifically to improve economics and reduce environmental impacts of landfills. Studies suggest the new process generates a net annual revenue, without a subsidy, and reduces carbon emissions from the landfill by more than 50%.
