What BioCNG does

BioCNG, LLC is a Madison, Wisconsin-based engineering and technology firm that designs, manufactures (via exclusive partner Unison Solutions), and commissions biogas conditioning systems used to convert raw biogas from landfills, wastewater treatment plants (WWTPs), food/organics digesters, and agricultural digesters into vehicle-grade compressed natural gas (CNG) fuel meeting SAE J1616 standards. The company's core product line consists of four modular, scalable unit sizes (BioCNG 50, 100, 200, and 400) processing 50 to 2,000 scfm of biogas to produce 100 to 10,000 gasoline-gallon-equivalents (GGE) per day. Treatment removes hydrogen sulfide, moisture, siloxanes, volatile organic compounds, particulates, and carbon dioxide, with fully automated operation and a fuel-quality guarantee tied to inlet gas standards. As of the most recent data, 11 BioCNG systems were operating across nine U.S. sites spanning Wisconsin, California, Colorado, Louisiana, and Michigan, drawing biogas from landfills, WWTP digesters, and food/green waste digesters.

BioCNG's commercial model combines hardware system sales with a professional services wrapper that includes site evaluation, plant design, permitting support, financial pro forma preparation, construction management, and operator training. The company is co-inventor of the patented conditioning system and operates through both direct enterprise sales to municipalities, landfill operators, and WWTP owners and through channel partners such as ANGI Energy Systems (fueling stations) and Air & Gas Technologies (Northeast CNG infrastructure). Since November 2015, BioCNG has operated as a subsidiary of Tetra Tech, Inc. (NASDAQ: TTEK), an engineering-consulting firm ranked #1 in U.S. solid waste and environmental management practices, which extended BioCNG's project execution capacity and integration into larger solid-waste and environmental engineering engagements. Production costs are reported in the $0.65 to $1.15 per GGE range, allowing end-user fleets to procure fuel at roughly half the cost of gasoline/diesel while qualifying for federal Renewable Identification Number (RIN) credits and various state incentives.

The company's primary customers are government entities (counties, parishes, municipalities, sanitary districts) operating landfills and WWTPs, alongside private refuse-hauling fleets (e.g., South San Francisco Scavenger, Atlas Disposal in Sacramento) and transit operators such as Grand Valley Transit. BioCNG also markets to fleet managers running return-to-base garbage trucks, transit buses, street sweepers, and municipal pickups, as well as to industrial food processors and agricultural operators with on-site anaerobic digesters. The business monetizes through one-time capital equipment sales, ancillary engineering services, and—where applicable—joint participation in federal RIN credit revenue generated by the renewable fuel produced.

Revenue model

1. Biogas Conditioning System Sales: BioCNG designs and sells biogas conditioning systems to municipalities, landfill operators, and WWTP operators. The company provides systems along with permitting, installation, and construction management services. Systems are available in standard sizes (50, 100, 200, 400 scfm) with modular expandability.
2. Federal Renewable Fuel Credits (RINs): Federal renewable fuel credits (RINS) are available for biogas-based CNG from landfills, wastewater treatment plants and manure/organics digesters. These credits provide additional revenue streams for BioCNG system operators.
3. CNG Vehicle Fuel Production: BioCNG produces and sells CNG fuel from biogas sources. Production costs range from $0.65 to $1.15 per GGE, allowing operators to sell fuel at approximately half the cost of gasoline and diesel while maintaining profitability.
