Minnesota’s Inver Grove Heights is getting a new renewable natural gas plant on its landfill, where biogases will be converted into natural gas. The plant is expected to be operational by March 2022 and will cost an estimated $40 million to build.
As landfill waste decomposes, it produces biogas, which is approximately 50 percent methane. Once the biogas is collected, the plant will treat it so it's pure methane and send it into the Xcel Energy pipeline. It will then be used to fuel a fleet of trucks that run on compressed natural gas.
The technology is new to Minnesota, but not to the rest of the country. There are approximately 70 similar facilities nationwide.
Inver Grove Heights city officials said the facility will have environmental benefits and be good for the city.
