Money from manure: from Oregon digester to Los Angeles freeway
October 21, 2019 by Capital Press
In June 2019, Oregon state regulators approved an expansion of Threemile Canyon Farms’ facility, and Threemile Canyon installed new equipment to purify the methane from its digester.
Threemile Canyon Farms is Oregon’s largest dairy with 68,340 cattle, including 33,000 milking cows. In 2012, the farm built an anaerobic digester to capture methane emissions from all that manure.
