More Tulare County Dairies To Pipe Biogas To Hwy 99 Plant

New Valley Biodiesel Plants In Works


Screen Shot 2017-04-18 at 12.24.44 PMCalgren Renewable Fuels is permitting some 20 miles of new pipeline in Tulare County to connect Pixley-area dairies to Calgren’s biofuel production plant on Hwy 99.

Calgren president Lyle Schlyer says the company currently connects to just one dairy but will increase biogas volumes by as much as 20 times when the project connects to a number of nearby dairies up to several miles away by the end of 2017 and into next year.

The biogas, collected from covered lagoons at dairies, is both a problem for the diaries and “an opportunity for both of us” adds Schlyer – replacing fossil fuel natural gas for the boilers at the Calgren plant with biogas “lowering our carbon footprint.”

“This is the kind of project people talk about but we are going to get it done” says the Tulare County biofuel maker.

California dairies are under the gun to reduce their methane emissions with some operators looking to spend money for expensive on-site dairy digesters. But this approach to fighting climate change allows dairy operators to export the stuff to a much larger digester at the Calgren plant, allowing them to concentrate on what they know best- milk production.

Schlyer says the gas will be used at the plant for cogeneration, making electricity along with making ethanol. He says the firm is interested in other possible uses for the gas as a transport fuel, for example.

Biodiesel Plant In Works

Calgren is also building a $9 million biodiesel plant at their site using some $3.5 million in grant monies from the California Energy Commission (CEC) to help to pay for this new renewable diesel facility. Like the ethanol they produce the new biodiesel fuel will be sold into the Fresno market.

Schlyer says the plant will test new technology enabling them to handle tougher greases,difficult to process for most biodiesel producers.

Schlyer says the 5.4 million gallon biodiesel plant should be operating by years end. The waste heat from the biodiesel plant built on half an acre will be used at the plant making the whole operation more efficient says a state report.

The CEC is funding several other Valley biodiesel plants this year including two at the Lost Hills Wonderful nut processing plants using shells as a feedstock and in Bakersfield at the state’s largest biodiesel plant run by Crimson Renewables.

The CEC its also funding another dairy biogas collection concept in Kern County with 15 dairies supplying 1 billion cubic feet of biogas a year to a central digester plant.

The dairy industry in the Valley blasted the state for implementing the tougher rules on methane reduction – but now some good could be coming out of it.

Last year Jerry Brown signed a law aimed at cutting methane emissions from cattle operations, thought to be the largest source of heat-trapping methane in the state, mostly from dairy manure.The new law requires the livestock industry to cut methane emissions to a 40 percent of 2013 level by 2030. The state Air Resources Board mandates that 75 percent of the cut needs to come from the state’s dairies.
