Loess Hills Regional Sanitary Landfill RNG Plant
The Issue
In 2019, Waste Connections acquired the Loess Hills Regional Sanitary Landfill in Malvern, Iowa. The landfill operated a gas capture system with a flare but lacked an on-site facility to beneficially convert the landfill gas into energy.
Our Solution
We invested approximately $40 million and worked with ESI, in collaboration with Kinder Morgan, and bp to construct a state-of-the-art Renewable Natural Gas (RNG) plant capable of processing up to 4,000 Standard Cubic Feet per Minute (SCFM), along with a pipeline to connect with the grid. The multi-step plant treats the landfill gas to pipeline-grade methane and seamlessly integrates the gas into Kinder Morgan's pipeline network.
The Benefit
The focus on gas capture at the site is expected to reduce fugitive emissions. At the same time, increased delivery of less carbon-intense RNG into the local pipeline displaces fossil fuel-derived sources, benefiting the environment. Additionally, the investment is expected to generate attractive returns for Waste.
