A Wisconsin project dubbed the “world’s largest manure biogas project” emits nearly 5,000 metric tons of climate-warming methane annually, roughly equivalent to emissions from 30,000 gasoline-powered vehicles, according to state data that adds to concerns about the impacts of large-scale manure digesters.
Five years after the US Department of Agriculture (USDA) guaranteed more than $100 million to what’s billed as the “world’s largest manure biogas project”, the loans are in delinquency, which, along with operational failures and underperformance at such plants, has seemingly prompted an agency-wide pause on loan guarantees for such projects, according to The New Lede’s analysis of federal data.
More than 30 food, health and environmental organizations are urging the US Department of Agriculture (USDA) to disqualify digesters that turn animal waste into gas from a federal renewable energy grant program, alleging that such funding causes pollution and benefits large factory farms.

Industrial-sized livestock operations have long been known for contaminating the environment and mistreating animals. Now, amid growing government incentives to turn the manure generated at these operations into climate-friendly biofuels, there are mounting concerns that the efforts could make industrial farming bigger and more dangerous.
