Varcor: From Dairy Waste to Drinking Water

The VarcorTM system from Washington state-based Sedron Technologies converts dairy manure into high-value components in a continuous closed loop, all without tractors, manure spreaders, or waste lagoons.

Natural gas could power new chapter in manure-to-energy

July 13, 2022 | Marc Heller

Unlike electricity generated from methane, renewable natural gas doesn’t have to be sold to a utility company and put on the power grid, where returns are meager in most of the United States. Instead, it’s fed into pipelines and sold to municipalities or transit agencies for vehicles or to industrial users, generating credits under state clean air standards in California and, perhaps soon, New York and other states.

‘Cow power’ goes dark as manure-to-electricity fizzles

July 12, 2022 | Marc Heller

Absent a national commitment to make renewable energy from manure financially viable, cow power is unlikely to catch on the way its proponents hoped.

Scientist “confident” U.S. dairy will mitigate methane emissions

The U.S. dairy sector is well on its way to reaching methane emission mitigation, says Juan Tricarico, Ph.D.

Can Biodigesters Save America’s Small Dairy Farms?

May 16, 2022 | Anne N. Connor

Here’s a carbon markets crash course

March 11, 2022 | Abby Bauer

The phrase “carbon markets” gets tossed around often during conversations about sustainability and agriculture, but how many people truly know what a carbon market is and how their farm could participate in one?

Sustainability in Agriculture

February 6, 2022 | Farm Bureau

America’s farmers and ranchers are leading the way in climate-smart practices that reduce emissions, enrich the soil and protect our water and air, all while producing more food, fiber and renewable fuel than ever before. U.S. agriculture contributes just 10% to overall GHG emissions, far less than other major industries, and plays an active role in enhancing wildlife and absorbing carbon.

The New California Gold Rush into Anaerobic Digesters

February 4, 2022 | Chuck Abbott

Each cow on a farm with a digester can generate $2,827 a year in air pollution and biofuel credits for methane that would otherwise go into the atmosphere.
