Gulf Alternative Energy to convert plant to cellulosic ethanol

Texan bioethanol producer Gulf Alternative Energy (GAE) is to use its new cellulosic feedstock preprocessing technology to convert a first-generation bioethanol plant to cellulosic ethanol production.

The company has signed a letter of intent with Xethanol Biofuels to purchase a plant in Blairstown, Iowa. The plant is currently producing six million gallons of ethanol a year from first-generation feedstock.

GAE plans to retrofit the plant with its new technology, which speeds the conversion of mixed second-generation feedstocks into simple sugars for conversion to ethanol. The new feedstock will be a mixture of agricultural waste products such as corn stalks, corn cobs and switchgrass.

‘We have spent several years developing our cellulosic feedstock preprocessor and now we are ready to put it to work in an existing ethanol plant,’ notes GAEC president John Shear.

GAE’s long-term plan is to purchase other first-generation ethanol plants and retrofit them to produce cellulosic ethanol.
