(Bioenergy Insight) Canadian ethanol producer Calgren Renewable Fuels has invested in key co-products to sell in addition to its 58 million gpy ethanol output.

The Calgren plant, located in Pixley, California, was the state’s first when it was built in 2009.

Today, the company also sells 400,000 tpy of distiller’s grain for use as animal feed to local dairies and feedlots as well as 1.5 million gallons of corn oil that serves local poultry producers and biodiesel facilities.

Calgren uses dairy manure biogas, made at the company’s new digester, to fire the boilers at the refinery, turning a waste product into a useful low-carbon fuel with the heat generated also making electric power.

As by-product of that process, the dried manure solids that are discharged at the back end of the digester cycle, are trucked back to a dairy every day to be used as bedding for the herd.

Now, Calgren is adding another by-product of the process, namely electricity generated from the expanded cogeneration operation. READ MORE
