Blue Sun launches commercial-scale enzymatic biodiesel process
Blue Sun Energy announced the implementation of the company’s new enzymatic biodiesel processing technology at its 30 MMgy production facility in St. Joseph, Mo.
“We have fully commercialized the enzymatic process technology and the plant is operating at full commercial scale,” says Blue Sun CEO Leigh Freeman.
Sean Lafferty, vice president of technology and new business, says, “Blue Sun can use essentially any feedstock without limit to free fatty acid content. This reduces pretreatment requirements and costs significantly. Blue Sun’s feedstock advantage alone can yield a savings of 10 cents per pound of feedstock, or 75 to 80 cents lower cost per gallon of finished biodiesel.”
Blue Sun’s process is more efficient in methanol recovery and use, further reducing costs. Also, the value of the glycerin produced is much higher than in standard biodiesel operations—20 to 30 cents per pound versus less than 10 cents per pound traditionally.
“Commercial operations using the enzyme would not have been possible without the many discoveries and inventions of the skilled engineers at Blue Sun, and the support of our partner, Novozymes,” says Bruce Baughman, chief operations officer. Its process utilizes Novozymes’ Callera Trans L enzyme.
Blue Sun says it will soon announce its next technology breakthrough, a major milestone in renewable diesel.
