LONDON, ONT. – RE Energy will update and expand its existing facility in Kalundborg, Denmark, to supply over 4 million kilograms (8.8 million lbs) per year of Arrabina prebiotic fiber from Comet Bio through an investment. RE Energy, an REE Holding company, will operate the facility under the supervision of Comet Bio, which recently competed a $25 million Series C financing. Some of the proceeds will be used for the investment in Denmark.

Based in London, Ont., and Schaumburg, Ill., Comet Bio uses its patented upcycling technology to produce ingredients from crop leftovers. The company extracts the prebiotic fiber arabinoxylan from sources such as wheat straw, brewer’s grain, corn stover and pea husks. The RE Energy facility will partner with Danish farmers to source wheat straw for Arrabina brand arabinoxylan, which has been clinically proven to promote growth of beneficial bacteria in the gut, help maintain healthy blood glucose levels and support immunity.

“RE Energy is a great partner, and we are excited to be investing with them to build a dedicated manufacturing facility,” said Rich Troyer, chief executive officer of Comet Bio. “This partnership will allow us to serve our customers’ needs for a prebiotic fiber that is fully soluble and easy to add to nutrition bars, baked goods, beverages or any other format that consumers go to for gut health benefits.”

RE Energy’s facility is part of the Kalundborg Eco Industrial Park, an industrial network of private and public companies in Kalundborg. The RE Energy facility uses renewable power. The Comet Bio investment will enable ultra-low-carbon production of Arrabina as well as existing production of biofuel and lignin.
