Sustainable Power (PINKSHEETS: SSTP) in Natchez, Mississippi, a division of controversial alternative fuel company U.S. Sustainable Energy (PINKSHEETS: USSE), is trying to turn dried distillers' grains (DDGs) and old cars into fuel.

DDGs are widely recognized as a relative benign organic byproduct of the conventional ethanol manufacturing process.

"Automobile fluff" is perhaps less well known. It's the trade name for leftover remnants from the dismantling process of motor vehicles. Currently, it undergoes remediation and is disposed of in landfills at high costs to its handlers and the environment.

It's known to contain many hazardous materials, is one of the leading sources of mercury contamination, and had been declared "hazardous waste" by the State of California.

This morning, Sustainable Power Corp. said in a statement that it's been turning it into fuel through its parent company's modified pyrolysis-based "Rivera Process," credited to USSEC founder John Rivera, and getting great results.

The numbers aren't worth repeating here, because no units were given and they were all asterisked as not yet having been independently verified, but the company claims to be able to produce significant amounts of biogas, in addition to liquid and carbon, from both DDGs and auto fluff.

Yes, that's right. Biogas from car parts. Not syngas, biogas.

A small, odd private company called BioCentric, with a bizarre web site, issued a release today with Sustainable Power, claiming to be supplying the company with 20,000 pounds of DDGs and auto fluff for further experiments.

The company says it has witnessed the Rivera Process in action, and pledges to "further define and verify this technological process" by bringing an expert along for further tests and discussions.

Sustainable Power Corp. is working to develop and manage green power plants utilizing USSEC's process.
