The Lamb Weston facility in RichlandWashington, processes almost one billion tons of potatoes annually. The Lamb Weston biodigester treats the water, handling up to 29 million gallons daily.

The digester biogas is upgraded into pipeline-quality RNG and injected into Cascade Natural Gas Corporation’s local distribution.  

Pine Creek is responsible for all construction, operations, maintenance, and financing of the Lamb Weston RNG upgrading facility, including pipelines and interconnections.

Pine Creek RNG has standardized on common Pressure Swing Adsorption gas upgrading, flare & thermal oxidizer, and compression technology for all of its project sites.  

Our sites use common controls, are remotely monitored and controlled, report to a central network operations center, and are continually observed for site optimization opportunities.

Pine Creek’s standardization of plant upgrading, combustion & compression hardware, site monitoring & controls, combined with ongoing wellfield monitoring and tuning, significantly lowers the levelized cost ($/MMBtu) of production.
