Greenbelt Resources Corporation announced that the bioethanol produced from its ECOsystem process meets the high standards of Natures Comfort Meds Biotechnology (NCM Biotech) for use in performance testing of its patented CBD (aka canibidiol) extraction process. The bioethanol tested was produced from local brewery waste, a feedstock targeted for use by Greenbelt's Paso Robles ECOsystem (PRECO). When complete, PRECO will be a waste-to-energy interconnected system (ecosystem) designed to produce half a million gallons of bioethanol from a variety of feedstocks available in the Paso Robles area.
