Thumb Bioenergy LLC

Thumb Bioenergy LLC, a for-profit limited liability company and goods manufacturer based in Sandusky, Michigan, receives federal grants from the U.S. Department of Agriculture's Rural Business Cooperative Services for advanced biofuel production and biofuel-sector pandemic relief. The vendor operates exclusively as a grant recipient; it holds no federal contracts as a prime or subcontractor.

Thumb Bioenergy's federal footprint consists entirely of USDA Rural Business Cooperative Services grants awarded over the past twelve years. Recent awards include a Project Grant for Production of Advanced Biofuel granted January 26, 2026 (completion date January 26, 2026), a COVID Relief for Biofuel Producers grant awarded May 26, 2023 (completion date May 26, 2025), a Production of Advanced Biofuel grant awarded July 1, 2022 (completion date March 3, 2023), and a COVID Relief for Biofuel Producers grant awarded May 5, 2022 (completion date May 5, 2024). All twelve awards documented in the source came from the same federal grantor, the USDA Rural Business Cooperative Services.

Activity has been sparse and episodic. The vendor received two awards in 2020, one in 2021, two in 2022, one in 2023, and one in 2026, with a two-year gap between 2023 and 2026. Combined obligations across all twelve awards total $180 thousand, indicating small grant values characteristic of rural cooperative and producer-relief programs rather than large development initiatives. The vendor does not appear in the federal contracting system and has no subcontract relationships documented in the source.
