How many have seen a real life biogas plant in their own country?
Answer:
I have worked nearly 20 years for Thames Water as a Chief Engineer and they have a Sludge Gas plant in Edmonton which also now re-cycles municipal waste. Information available from: Thames Water, catherine.cook@thameswater.co. or Web Site:

I also am a Fellow Member of the Institution of Diesel and Gas Turbine Engineers (IDGTE) which have many members working or running Life BioGas Plants, info at: enquiries@idgte.org

Why yes;
TVA (Tennessee Valley Authority) uses methane gas from wastewater from the city of Memphis, TN, US.
Sadly, it is co-fired with coal, so it is not entirely petroleum independant.
My electrical utility, Washington Electrical Co-op, gets its largest share of electricity from methane burners at the Coventry Landfill (http://www.washingtonelectric.coop/pages... ) The process is so cheap that we're practically the only electrical customers in the region not to be facing big rate increases these days. Besides that, methane is a much worse contributor to global warming than carbon dioxide, so by burning the methane, the utility is making a huge contribution to decreasing greenhouse gases.
Recycling is an entirely different story, which has nothing to do with methane generators or biogas. Recycling diverts reusable materials from the landfill, which is also highly desireable. But once the stuff gets into the landfill, especially compostable materials, and starts breaking down, it creates methane, and that's what powers the generators.
