The pipeline will transport the renewable biogas from the dairies to the Aemetis biogas upgrading facility at the Aemetis ethanol production plant in Keyes, California, where the biogas will be transformed into commercial-grade renewable natural gas (RNG) for use as a carbon-negative transportation fuel for trucks, buses, and cars.

After a procurement process that included proposals from ten pipeline construction companies, Aemetis selected Machado & Sons due to their extensive experience in utility-grade pipeline construction, as well as their successful completion of a separate carbon dioxide (CO2) pipeline from the Aemetis ethanol production facility in Keyes to the CO2 liquefaction gas plant that was built in 2019.

The company is also currently engaged as a key construction contractor for the Aemetis biogas upgrading facility.

Through a competitive bidding process with a number of highly qualified pipeline contractors, Aemetis is very pleased to select Machado & Sons for the second stage of the dairy biogas pipeline construction. Over the past few years, we have completed a number of projects with Machado & Sons, and continue to be impressed with their collaborative attitude, outstanding safety record, and exceptional construction capabilities said Andy Foster, President of Aemetis Biogas.
