What American GreenFuels does
American GreenFuels, LLC is a Connecticut-based manufacturer of premium biodiesel, operating what is described as the largest biodiesel production facility on the US East Coast from an integrated site at the Port of New Haven (30 Waterfront Street, New Haven, CT). Founded in 2012 as Greenleaf Biofuels and acquired by Kolmar Americas, Inc. — the US subsidiary of Swiss-based Kolmar Group AG — in 2015, the company converts plant oils (soybean, canola, palm, corn) and animal fats/used cooking oil into fatty acid methyl esters (FAME) via the transesterification chemical process. Production capacity has grown from 15 million gallons annually in 2016 to more than 60 million gallons per year following a major turnaround and expansion completed in June 2025, supported by direct access to truck, rail, and ocean barge logistics at the New Haven Terminal.
The company's commercial offering consists of a core biodiesel product and a complementary Bioheat line (biodiesel blended with heating oil). Revenue is generated through B2B volume-based sales to Northeast US biodiesel and diesel blenders, diesel resellers, heating oil suppliers, transportation fleets, and industrial users, with occasional export to international biodiesel markets. Pricing is not publicly disclosed and is negotiated bilaterally with B2B counterparties. Growth is supported by state-level blending mandates requiring increasing biodiesel content in heating oil (notably in Connecticut and the broader Northeast) and by federal incentives including the biodiesel tax credit and EPA Renewable Fuel Standard (RFS) program participation.
American GreenFuels holds BQ-9000 Producer certification from the National Biodiesel Accreditation Commission and operates as a privately held, wholly owned subsidiary of Kolmar Americas; parent Kolmar Group operates more than 20 offices worldwide sourcing and marketing petrochemical, petroleum, gas, and renewable fuel products. Operations are concentrated at a single New Haven production site with corporate oversight from Kolmar's Shelton, CT headquarters (3 Corporate Drive, Suite 500). Headcount of 50+ (many veterans) has more than doubled since the 2015 acquisition. The company has been an active participant in industry advocacy, hosting Senator Blumenthal and Congresswoman DeLauro at the facility and working with the Connecticut Energy Marketers Association and National Biodiesel Board. Notable recent events include a $143,000 EPA Clean Air Act settlement in September 2024 covering 2020–2022 violations, and a June 2025 capacity expansion to over 60 million gallons annually.
