The new garbage incinerator here in Uppsala is a state-of-the-art CHP system. A bit over 100 MW IIRC.
Of course, incinerating garbage does pose the problem of rendering unrecoverable a number of non-renewable raw materials that could otherwise have been reused.
This problem is easily overcome. When Sweden signed the antipersonell mine ban treaty and couldn't use AP-mines anymore, we renamned them "defence charges". Hence, we got the brilliant idea of renaming garbage incineraion "energy recycling". ;) Peak oil is not an energy crisis. It is a liquid fuel crisis.
It's the copper, aluminium and iron that goes up in the air and is scattered to the winds...
Or, at best, is oxidised so far into uselessness that recovering them becomes a real energy hog.
