Our trash isn't recycled into energy, it is destroyed (burned) to extract energy. Except for some metals, the original material no longer exists to be reused.
I suppose if you insist on calling trash-to-energy a form of recycling then every engine that burns a petroleum product is also a recycling system that recycles oil into energy.

Burning leaves various kinds of altered materials behind. Like wood fire in a fireplace leaves ashes and smoke and various gases, burnt trash leaves stuff, too. What kinds of stuff depends on what the trash consists of. So, the questions I have are, what does the waste from burning consist of (metals, glass, plastic gunk, ash)? Is any of the waste toxic or harmful to the environment in any way.? How is the residue or waste from burning disposed of. What happens to it?
Burning oil, coal, natural gas, to create energy produces some pretty nasty by products. What about trash? Just how clean ( or unclean) is it
?
