An Arizona Dairy Farm is Turning Cow Manure into Renewable Natural Gas
It all starts here - with 25,000 dairy cows at Butterfield Dairy Farm in Buckeye.
"Me and my three sons built this dairy, there was no contractor here, they did it all," said owner Thomas De Jong.
The De Jong family bought land in Buckeye in 2003. They finished their first dairy in 2008 and their second in 2018, but the owner says his family has been in the dairy business since 1620.
