Chromatin and Calgren Renewable Fuels Sign Multi-Year Alliance for Locally-Grown Sorghum for Ethanol Production

Feb 25th, 2013

Chromatin, Inc., a leading provider of innovative crop breeding technology, sorghum seed products and feedstocks, and Calgren Renewable Fuels, a leading ethanol producer located in Pixley, CA, announced today an alliance to develop a local supply chain for sorghum for the production of fuel ethanol and distiller’s grains. The multi-year agreement covers up to 30,000 acres of sorghum grain to be grown and supplied to Calgren, which produces over 55 million gallons of ethanol annually.

 “We are delighted to be working with Calgren Renewable Fuels – which has been continuously involved with ethanol production since 2009 – in our commitment to expand the use of locally-grown sorghum crops in California for the production of energy-efficient biofuels,” Chromatin Chief Executive Officer Daphne Preuss said.  “Growers located near the Calgren facility recognize the benefits of growing a water-efficient crop like sorghum, and we are pleased that our products provide an affordable alternative to corn that can be used in ethanol production.”

 ”In areas of the Central Valley with water constraints and higher alkalinity soil sorghum looks like an especially good choice. In addition, preliminary tests suggest the protein level of our distiller’s grains may improve a bit,” said Lyle Schlyer, Calgren’s President. “We like the prospect of giving local farmers and dairies better options.” 

 Chromatin is working with California growers who are attracted to sorghum’s water efficiency and tolerance to heat, as well as the cost benefits that come from reduced fertilizer use. In addition, the residue left over from the harvest of sorghum grain can be used as high quality animal feed, or as a feedstock for biogas or cellulosic biofuel production.

 Ethanol plants in California have been seeking alternative crops to corn to reduce feedstock costs, to improve their carbon footprint and to source feedstock from locally grown energy-efficient crops. The EPA recently identified conditions in which sorghum, as an energy efficient feedstock, can qualify for the financial incentives related to producing Advanced Biofuel.

 About Calgren Renewable Fuels 

Calgren operates the longest running fuel ethanol plant in California, continuously supplying ethanol, distiller’s grains, and corn oil to areas in and around Bakersfield and Fresno, CA since 2009. With its unique, energy-efficient process, its fuel ethanol has one of the lowest carbon footprints in the country.
