No, it works. People just complained about the smell and local regulators keep preventing expansion.
The most creative use of that technology would be to rid a city of solid waste in order to produce oil, minerals and distilled water. Get rid of sewage and produce power? A win on both accounts.

Actually, the process works. The issues they ran into were:
1) Environmental -- right or wrong, local residents complained about foul (no pun intedned) odors coming from the plant, and
2) Cost -- they had expected in the wake of "mad cow" issues that the feedstock would essentially be waste that would not cost them anything, but restrictions on feeding animal parts back to animals never happened. Additionally, they were never able to get the language changed that would have allowed them to claim biofuel tax credits.
