South Hills upgrades landfill biogas to produce RNG that will be sold in the vehicular transportation market as renewable compressed natural gas. Production at the facility is expected to exceed one million gallons of renewable fuel per year. Green Rock has partnered with United Green Energy, and others, to manage the renewable natural gas offtake.

RNG is derived from renewable sources, such as organic waste from landfills, municipal waste from wastewater operations, or animal waste from agriculture operations. The production of RNG reduces greenhouse gas emissions by capturing the methane emissions produced from the decomposition of these waste products.
