Need Landfill Gas, Bio-Gas Or

Other Renewable Natural Gas (RNG) Pipeline Services?

USDI supports many owners and producers of RNG through successful design and operation of their RNG pipelines, from the plant to the end user.  Whether the end user be another pipeline, local gas distribution system, or a private customer, USDI can provide a tailored solution to fit your budget.

USDI is quickly becoming a leader in the operation and field services to RNG pipeline facilities.  We currently work with nearly twenty (20) RNG pipeline facilities across multiple states, including Nebraska, Wisconsin, Missouri, Michigan, Ohio, Pennsylvania, Kentucky, Virginia, Tennessee, North Carolina, Arizona, and Indiana.  Most of these pipelines carry unprocessed landfill gas, however, there are several that process, clean, and compress the gas to pipeline quality.  USDI is also working on pipeline projects that are creating RNG from sources other than landfills, such as methane from animal waste and anaerobic digestion of grass or other stock.  USDI is your full service RNG resource as we can provide design, inspection, construction, and operation of your pipeline.  If you also need assistance on the production side of the pipeline, USDI has successfully partnered with several experts in the production field and can work with you to find an appropriate solution.
