06 Jan 2014 --- Once a buzzword in the biofuel industry, algae are gaining attention for their application to the feed and food industries as a highly sustainable source of protein and DHA omega-3 enrichment. As such, Alltech is continuing to expand its algal DHA plant in Winchester, Ky., USA, one of only two plants in the world commercially producing a high-DHA heterotrophic microalgae. The facility, which is capable of producing approximately 15,000 tons of algae, has already been updated since its opening in early 2011.
