Burning trash isn't really plausible due to the heterogenous nature of trash.
The stuff is a mixup of everything: tires, coffee grinds, diapers, lots of paper, stuff like that (mainly paper.)
Paper generates lots of bad stuff, tires...*whoa*, and many of the things we throw out (plastic!!) have chemicals for which high energy (fire) acts as a catalyst and releases harmful vapors which have no use.
Try something like superconductor-based turbines maybe?
