MIDDLETON, Wis. (Aug. 11, 2022) – EnTech Solutions, a clean-energy solutions provider, Peterbilt Motors Company, a division of PACCAR, and Maki Trucking, LLC, a regional transportation firm, are partnering to further the sustainability efforts of the Middleton digester renewable natural gas (RNG) facility by incorporating an electric vehicle (EV) tanker truck to transport the facility’s RNG fuel. The Peterbilt Model 579EV will deliver the RNG to the Dane County landfill facility, where it’s injected into the natural gas pipeline to be used as clean transportation fuel on the west coast. U.S. Gain, a division of Wisconsin-based U.S. Venture, Inc., offtakes the RNG for distribution to the transportation market in California.
Electric vehicle transportation is the next step in the Middleton digester’s clean energy endeavors. Maki Trucking is adding the Peterbilt 579EV to its fleet to support the 44-mile round trip Middleton RNG transport route, with the ability to haul two to three loads per day. Clean power to the vehicle will be supplied by EnTech Solutions’ distributed energy microgrid at the Middleton site, with a PACCAR ChargeMax 120. Preliminary modeling indicates that implementation of electric vehicle transportation of the RNG will reduce up to 116 tons of CO2 emissions annually.

The biodigester facility converts agricultural waste from four regional dairy farms into RNG, eliminating greenhouse gas (GHG) emissions normally released by the dairy manure. The site is powered by a distributed energy microgrid that utilizes solar power and battery energy storage to produce more than 2.8 megawatts (MW) of clean energy annually, enough to power more than 400 homes. The addition of EV transportation of the fuel further reduces the RNG’s carbon intensity (CI) score.
“Peterbilt is proud to be leading the charge in medium- and heavy-duty zero-emission truck deliveries,” said Jason Skoog, Peterbilt general manager and PACCAR vice president. “Partnering with Maki Trucking to put the Model 579EV to work hauling clean fuel, powered by clean energy, showcases the level of sustainability that can be achieved with these advanced vehicles in the right applications.”
“Maki Trucking is excited about the expansion of renewable fuels and electric vehicles in the trucking industry,” said Joel Maki, owner. “After 38 years of burning diesel, it was time to look closely at alternatives. For this operation, the EV makes perfect sense. We have the power for the truck generated on-site, we have the product to haul, produced in a sustainable fashion, and we have the farmers to thank for their involvement. This EV is the final link to make it come full circle.”
A Peterbilt EV demo truck was recently at the Middleton facility where it transported multiple loads of RNG to the Dane County landfill pipeline.

“Our renewable energy and clean lakes partnership with EnTech Solutions continues to grow stronger and more climate-friendly with the addition of an electric vehicle tanker truck to haul RNG to our Dane County landfill,” said Dane County Executive Joe Parisi. “Eliminating the burning of diesel fuel and charging the EV truck with on-site solar power at the Middleton digester is a cutting-edge investment to further reduce carbon emissions.”
“EnTech Solutions is on the cutting edge of clean energy technology,” said Dan Nordloh, executive vice president and general manager of EnTech Solutions. “Partnering with Peterbilt and Maki Trucking to transport the clean RNG produced at our Middleton digester facility demonstrates our commitment to proving that these clean-energy options are available and are viable solutions to lessening the environmental impacts of the agriculture and transportation sectors.”
