Biodiesel quality improving, says federal lab
4/21/08

A recent sampling of biodiesel showed that overall quality has improved, but significant lapses still exist, reported the U.S. Department of Energy’s National Renewable Energy Laboratory.

Nearly 90 percent of samples met federal standards, the lab reported. Small-to-medium producers had significant failure rates, while larger producers fared well, the Golden, Colo., lab reported.

To be a legal fuel and qualify for tax credits, biodiesel must meet American Society of Testing and Materials International D6751 specifications. To test compliance, the laboratory collected samples of B100, or 100 percent biodiesel, directly from U.S. producers between April and November 2007.

Of 107 producers then in the market, 56 participated, representing 70 percent of the U.S. market in 2007, the lab reported. Most often, the remaining producers were unresponsive to multiple attempts to collect a sample, the lab reported.
