Piedmont Biofuels scales-up its new enzyme-based biodiesel system

February 7, 2012 |

In North Carolina, Piedmont Biofuels announced that the company has successfully scaled-up an enzyme-based technique to biodiesel production. The traditional biodiesel production method uses chemical catalysts like potassium hydroxide and sulfuric acid. These chemicals form soaps or salts which contaminate both the biodiesel and glycerin phases, producing low-grade co-products.

“With the enzyme process, we eliminate the caustic chemicals which allows biodiesel producers to decrease waste and increase yield, with all types of feedstocks,” says Lyle Estill, President of Piedmont Biofuels. Piedmont Biofuels has been investigating enzyme catalysis for the biodiesel industry for over four years in efforts to find a successful zero-waste output. In 2009, Piedmont began collaborating with global enzyme producer, Novozymes.
