Kings County Dairyman Cuts Diesel Emissions 92% With Electric Mixer
By Laurie Greene, Editor
On his dairy in the Kings County town of Hanford, Philip Verway reduced his diesel consumption a remarkable 92% from 7,000 to 500 gallons in a given three-week period. His innovative secret to cutting diesel emissions is converting a diesel-powered commodity mixing machine to an electric mixer.
Kevin Abernathy, director of environmental services for the Milk Producers Council, said, “Rob Vandenheuvel, General Manager for Milk Producers Council, Philip and I helped him get a grant from the San Joaquin Valley Air Pollution Control District, a state-appointed board which aims to minimize diesel exhaust output. We put together a proposal, submitted it, and their governing board actually approved the grant. What began as a concept on paper led to the reality of the processes being implemented on-farm. We had it up and running in about three months. Most importantly, the end results are not only meeting, but exceeding our expectations,” said Abernathy.
The entire operation dramatically reduces total nitrogen oxides (NOX gases), pollutants in the San Joaquin Valley, “Our initial expectation based on the modeling was 22 tons of NOX emissions.” The post-project NOX rates were about two tons—a major reduction.
Abernathy said Verway worked with contractors Duport and Supreme to engineer the electrification of the vertical mixers and built some fail-safe components into the system. Impressed, Abernathy said, “Based on what I have seen, they have done a remarkable job, particularly on the multiple fail-safes. Hats off to Duport and Supreme for coming up with technology that works day-in and day-out, 365 days of the year.”
Abernathy also admired the ingenuity in the California dairy industry, “They continue to come up with some of the most extraordinary ideas. It is an absolute blessing to work with them, and they make my job so much fun with projects like this!”
