Please provide links to the articles you mentioned. I'm left to speculate without more information. Regardless, I have to disagree. The current ASTM standard isn't something that is enforced; once a Bio-diesel producer demonstrates that their production facility can make ASTM standard fuel, they are free to produce and sell whatever they want, with no quality enforcement. (I'm not sure what the BQ9000 standards are, so perhaps they are different.)
This article, among many others that can be found, discusses the issue: http://www.twincities.com/mld/twincities/business/15984811.htm
Quote from the article:
...word came of large-scale [Bio-diesel] quality problems elsewhere, based on a
series of tests on pure biodiesel performed by the National Renewable
Energy Laboratory and co-funded by the biodiesel industry. "[Fuel samples] were taken from all over the country," said George Douglas, a
laboratory spokesman. "And the failure rate was about a third."
Having a voluntary standard isn't working. Realistically, we need enforcement of the standard to have consistent, quality Bio-diesel. It's inconvenient, but changing to alternative fuels requires the two largest industries (vehicular and energy) in the US to retool; It's difficult to fault them for wanting a quality alternative to change to.
Keep in mind you're free to make and use whatever quality of fuel you want. In my opinion, this is likely to remain, as regulation of independent producers would be difficult, expensive, and would provide little in the way of "public good".
