Trash to Treasure: America’s $3B Biogas Surge

Investors pour billions into U.S. biogas as waste-to-energy gains serious momentum

3 Nov 2025

America’s clean energy boom is finding new fuel in old waste. In 2024, the U.S. biogas industry pulled in more than $3 billion in new investment, pushing a once-overlooked technology into the mainstream of renewable energy. From landfills to dairy farms, waste is being transformed into renewable natural gas that powers homes, fleets, and utilities.

According to the American Biogas Council, over 2,500 biogas systems are now operating nationwide. Each captures methane that would otherwise leak into the atmosphere and converts it into usable energy. “This is the institutionalization of biogas,” said Patrick Serfass, the council’s executive director. “It’s scaling alongside wind and solar.”

Wall Street is watching closely. Infrastructure and clean energy funds now view biogas as a dependable asset class aligned with long-term climate goals. Federal incentives under the Inflation Reduction Act are adding fuel, especially through tax credits that reward projects turning waste methane into renewable fuel.

The results are already visible. By mid-2025, U.S. landfill gas systems were capturing roughly 521 billion cubic feet of biogas each year, enough to power more than two million vehicles.

Still, the rush to build is not without hurdles. Developers are running into supply chain snags, slow permitting, and evolving credit eligibility rules. Even so, optimism prevails as capital continues to flow and projects expand in states like California, Texas, and Iowa.

Biogas has moved far beyond a green experiment. It is becoming a central piece of America’s clean energy puzzle. As investors, farmers, and policymakers rally behind the promise of waste-to-fuel innovation, the next challenge will be scale, growing fast without losing environmental integrity.

What was once just garbage is now gold, and the biogas boom shows no signs of slowing.
