One Big, Beautiful Bill Signed into Law on Independence Day Strengthens Path to Prairie-Powered Renewable Natural Gas

Roeslein Renewables: Production Tax Credit Extension Will Accelerate Efforts to Restore 30 million Acres, Strengthen Rural Economies,
and Expand RNG Markets

ST. LOUIS, July 7, 2025 /PRNewswire/ -- Roeslein Renewables proudly celebrates the signing of the landmark "One Big, Beautiful Bill" legislation by President Donald J. Trump this Independence Day. The legislation includes a critical two-year extension of the Clean Fuel Production Tax Credit (Section 45Z), moving the sunset date from December 31, 2027, to December 31, 2029. This extension is a major victory for U.S.-produced renewable energy sourced from anaerobically digested livestock manure and biomass, and reaffirms the nation's commitment to rural revitalization, energy independence, and environmental stewardship.

Roeslein Renewables extends its sincerest thanks to President Trump, the United State Senate, and Members of the House of Representatives for recognizing the value of renewable natural gas (RNG) and for passing this crucial budget reconciliation legislation, which includes provisions critical to the continued growth of the U.S. biogas industry.

Bryan Sievers, Director of Government Relations at Roeslein Renewables, shared the following statement in response:

"With the passage of the One Big, Beautiful Bill, Roeslein Renewables is excited to see that cellulosic feedstocks, including swine manure, dairy manure, poultry manure and other types of manure, along with cellulosic biomass including winter-hardy cereal rye, native perennial prairie, and other crop residues will provide significant benefits to farmers, livestock producers, and producers of renewable natural gas that will drive development and capital investment in the livestock manure and biomass based anerobic digestion industry on our nation's farms and ranches."

Roeslein Renewables and Horizon II: A Living Example of Energy Innovation and Environmental Restoration

Horizon II is a commercial demonstration project featuring anaerobic digester facilities owned and operated by Roeslein Renewables in partnership with Sievers Family Farms. The farm consists of an 1,800-acre corn and soybean operation with a 2,400-head beef cattle facility owned and managed by the Sievers family.

This project exemplifies Roeslein Renewables' vision: restore 30 million acres of native prairies and grasslands — (approximately the area of Iowa), alongside 100 million acres of cover crops (roughly the area of Missouri and Kansas). When combined with livestock manure from thousands of small farms, these biomass sources have the potential to supply up to 17% of the nation's natural gas demand (RNG White Paper)².

Supported by the Section 45Z production tax credit, the co-digestion of livestock manure and biomass from native prairie and winter-hardy cover crops will not only provide clean, renewable energy but will also deliver major environmental benefits. These include significant reductions in nitrogen, phosphorus, and sediment runoff into waterways, as well as the creation of rich wildlife habitats across America's agricultural landscape.

Roeslein Renewables collaborates with Penn State University and Iowa State University on several USDA grants, including C-Change and Horizon II, which includes the creation of a video series called Prairie Prophets, that presents scientific data to support the vision of clean renewable natural gas production from rural America while addressing environmental challenges such as cleaner water, healthier soils, and improved air quality. These outsized ecosystem services and benefits will also generate substantial new revenue streams and create jobs for those who make their home in rural America, while simultaneously reducing the burden and costs to their communities' water purification systems, improving water quality in the Gulf of America, and supporting President Trump's "Make America Beautiful Again" Executive Order.

"Since founding Roeslein Renewables our overarching goal has been to provide farmers an alternative way to use land, especially highly erodible acres, in ways that will benefit the environment, wildlife, and their own livelihood," said Rudi Roeslein, Roeslein Renewables Founder and Chairman. 

Horizon II is certified under the International Sustainability and Carbon Certification (ISCC EU)³ and meets the requirements of the Renewable Energy Directive (RED II) (Directive [EU] 2018/2001) promoting the use of energy from renewable sources.
