US-based Chromatin has signed a multi-year agreement with Calgren Renewable Fuels to develop a domestic sorghum supply chain, for use in fuel ethanol production.

Calgren Renewable Fuels operates a fuel ethanol plant in California, which produces over 55 million gallons of ethanol every year.

As per the terms of the agreement, Chromatin will work with California growers and will facilitate the supply of sorghum grain that will be grown across 30,000 acres of farmland in the state.

Chromatin chief executive officer Daphne Preuss stated that the partnership with Calgren Renewable Fuels supports the company’s commitment to expand the use of locally-grown sorghum crops in California for the production of energy-efficient biofuels.

"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," added Preuss.

The remaining residue from the harvest of sorghum grain can be utilized as high quality animal feed or as a feedstock for biogas or cellulosic biofuel production.
