Biofuels

Air pollution, rising gas prices and geopolitical uncertainties over petroleum have increased interest in renewable, cleaner-burning biofuels such as ethanol and biodiesel.

Promising New Market

Ethanol is a gasoline supplement that is produced from starchy biomass through an enzymatic process, and biodiesel is a diesel supplement produced from plant oils through a chemical process. These fuels are made from organic matter that represents a promising new market for growers across North Carolina.

Efficient Biomass Resources

Though corn is the initial crop of choice for ethanol refiners throughout the Midwest and West, North Carolina researchers are seeking even more efficient sources of “biomass” or “feedstock” for ethanol refining here. Contenders include pine, switchgrass, canola and even algae and kudzu.

Enzymes developed through biotechnology are used to break down the sugars in starchy vegetation to make biofuels, and to convert cellulose from woody plants into ethanol.

New enzymatic technologies developed by companies such as Novozymes, which operates a major enzyme-production facility in Franklinton, N.C., will help reduce the cost of cellulosic biofuels so they can compete with traditional petroleum-based products.

North Carolina will have its first ethanol-manufacturing plant online in early 2009. Raleigh-based Clean Burn Fuels is developing a $100 million plant on 500 acres three miles southeast of Raeford — a town about 20 miles west of Fayetteville.

In addition, numerous small biodiesel processors and stations are springing up throughout the state.
