Yeah Bret, here's your feedstock for ethanol production. I told you
the bacteria would have to be wearing a blue suit with a red cape or
whatever. I wonder what thallium and PCBs do to internal combustion
engines.

Sewage-Based Fertilizer Safety Doubted
By JOHN HEILPRIN and KEVIN S. VINEYS Associated Press Writer
Mar 6th, 2008 | AUGUSTA, Ga. -- It was a farm idea with a big payoff
and supposedly no downside: ridding lakes and rivers of raw sewage and
industrial pollution by converting it all into a free, nutrient-rich
fertilizer.

Then last week, a federal judge ordered the Agriculture Department to
compensate a farmer whose land was poisoned by sludge from the waste
treatment plant here. His cows had died by the hundreds.

The Associated Press also has learned that some of the same
contaminants showed up in milk that regulators allowed a neighboring
dairy farmer to market, even after some officials said they were
warned about it.

The bacterial process and subsequent refining should eliminate them.
Ethanol is easy to clean. The remaining solid waste or sludge from
those plants, assuming they even work, would be really toxic.

Also the trouble wouldn't be to the engine but to the air as with
coal, high sulfur diesel, etc.

They occasionally use raw sewage in Mexico for some crops, whether for
fertilizer or just irrigation I don't know. Apparently the sun and
the plants do _not_ kill all the bacteria . . .
