Bio-methane from Organic Dairy Waste could be a 'New Gold Rush' on the Farm
The back end of a cow generates 80 pounds each day of what Dennis Haubenschild, who owns 750 of them near Princeton, refers to as a “non-depletable renewable resource.”
Now, technology and policy are aligning for farmers to take advantage of all that manure in a surprising way — by turning it into gas that can fuel vehicles.
Haubenschild was among the first dairy farmers in the state to experiment with biogas production, and he uses manure-turned-gas to generate heat on his farm. But climate change policies in California and Oregon have created a different, national market for the gas that comes from livestock manure.
