Instead of allowing it to be flared into the atmosphere, Air Liquide's Winnebago facility captures it at the landfill and purifies it into a pipeline-quality gas that is interchangeable with geologic natural gas. In some cases, RNG is one of the only energy sources that can have a negative carbon intensity on a lifecycle basis, depending on the feedstock. Nicor Gas' pipeline infrastructure is a vital component in enabling reduced emissions for those entities who are purchasing and/or retiring the environmental attributes and delivering energy to end users, as well as encouraging RNG development. The company will receive and retire 13,900 MMbtu annually of environmental attributes associated with this project, contributing directly to Nicor Gas' reduction in greenhouse gas emissions from its operations.
