he biodiesel industry’s largest trade group has issued a “winter weather advisory” after 50% of the samples in a national test failed to meet quality standards.
The test included a specification for glycerin, which clogged fuel filters in Minnesota last year.
Although National Biodiesel Board officials would not say where the samples came from, the National Renewable Energy Laboratory, a co-sponsor of the test, said none of the bad samples came from Minnesota, which set standards for the fuel after last winter’s clogging problems.
