Volkswagen, which introduced its Clean Diesel Technology on the race track in 2008, announced it’s using B5 biodiesel to power its race cars, transport vehicles and generators for the 2009 Jetta TDI Cup season.

And now they want your input on what those sustainable practices and standards should be — they’ve released the first draft of their “Principles and Baseline Practices for Sustainability” (PDF) to the public under a 45-day comment and review period.

So, if you’ve ever questioned the wisdom of growing our own fuel, or you’ve wondered how biofuels can be considered sustainable at all given other seemingly cleaner options like solar, wind and geothermal, now’s your time to speak up.

It’s early in the pre-dawn dark hours of the morning. A group of Northern California pseudohippies just finished a game of Zonk — or rather, the game just stopped because somebody quoted a line from Harold and Kumar Go to White Castle and everybody forgot what they were doing.

Yet, by a stroke of luck, the conversation about Harold and Kumar reminds the group of their real reason for staying up so late. They pack into a truck and head down to the local fast food joint looking to load up — but it’s not the food they’re loading up on, it’s the nasty, half-rotted, leftover fryer grease.

According to an article in the Jakarta Post, an official from the Indonesian government has spilled the beans on Samsung’s plans to invest up to $1.63 billion dollars in what’s sure to be a controversial acquisition of land for growing oil palms and construction of a biodiesel plant in Indonesia.

But first, a digression.

Part 1: When an egg was just an egg

I remember a time when an egg was just an egg. Nobody argued about that. It was a blissful time. Yet, for all its strengths, it was a fragile time held together by unsupported conclusions and limited knowledge.

Lack of warranty support for biodiesel has been a major stumbling block for new diesel owners who want to start using the fuel. But three long-awaited ASTM specifications could help change that.

Automakers and engine manufacturers have been requesting a finished blend specification for B20 biodiesel blends for several years, with some citing the need for that spec as the single greatest hurdle preventing their full-scale acceptance of B20 use in their diesel vehicles.

On June 19th, after more than five years of research and discussion, the American Society for Testing and Materials (ASTM) finally approved the following specifications for biodiesel fuel:

• Changes to the existing B100 biodiesel blend stock specification (ASTM D6751)
• Finished specifications to include up to 5% biodiesel (B5) in the conventional petrodiesel specification (ASTM D975)
• A new specification for blends of between 6 percent biodiesel (B6) to 20 percent biodiesel (B20) for on and off road diesel.

If that’s gibberish to you, here’s the take home message: the new specification for B6-B20 biodiesel blends could prompt more automakers to fully support B20 in their new cars and trucks.

Most of us are at least vaguely familiar with biodiesel, but how much do we really know?

While biodiesel is easily the most popular alternative fuel available, it’s commonly misunderstood or misrepresented by inaccurate information. Since the most frequent question I get is, “So what exactly is biodiesel, anyway?“, I decided to write a tome covering all the basics—a one stop shop for all your biodiesel- related questions.

It’s been exactly one year since I published the first Biodiesel Mythbuster on GreenOptions.com, and its popularity made a sequel inevitable. By way of a short introduction, here’s what I wrote last year:
