"Corporate pork and dairy producers are producing “biogas” to reduce methane emissions. But the actual climate benefits are unclear, and often overstated."
"When the world’s largest pork producer and a major public utility announced they would team up to turn hog manure from North Carolina swine farms into energy, they billed their new partnership as a win-win for both the companies and the climate.
With a $500 million commitment and a recently minted joint venture called Align RNG, Smithfield Foods and Dominion Energy set out to capture the methane emitted from giant hog manure “lagoons,” convert it into biogas—what the industries dub “renewable natural gas”—and inject that biogas into pipelines to heat homes and buildings.
The partnership, the companies said, would create the biggest manure-to-energy project in North Carolina, a state with the potential to become the largest producer of livestock biogas in the country. At the same time, the project would help the companies meet their goals of reducing climate-warming emissions, they said."
