NREL survey shows 95% of biodiesel samples achieved ASTM standards

In Colorado, the latest national survey of 100% biodiesel (B100) “blend stock” samples by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications. The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers – along with reliable operation of the nation’s vehicles powered by biodiesel blends.
