*** .I wonder why he haven’t figured out a way to burn our garbage
How Singapore does it.

Japan also.
The big problem is what to do with the ashes after everything is burned. In Japan they are using it as fill for land reclamation for now. https://www.youtube.com/watch?v=sAu3LVktMwE

hey...thanx for that. their recycling is strict...ours doesn’t even meet any standard...
The biggest issue with “trash” burning is generation of dioxins/dibenzofurans from inefficient combustion in a mixed waste stream.
Ideally, after you have mechanically separated out all the metal and glass fraction for recycling (or in latter case doing something like tumble grinding it for use as a silica adjunct to concrete or graded aggregate), you could shred a mixed paper/plastics waste stream in a ratio that’s amenable to blowing it into the combustion space with forced air and get a pretty decent efficiency of the combustion.
Otherwise, if you saw incomplete products being generated you could boost temperature with supplimental fuel, or further air or straight oxygen forcing.
As for the ash, you can either put it in concrete, or if it’s rich enough in needed elements, run it through an extractive process. Right now a huge use of metal processing slag is grinding up and using it as a cementitious concrete additive. It’s on the same line as Roman use of volcanic ash as an additive to their concrete (which remains a truly badass material).
Another waste management avenue I’m always puzzled hasn’t been explored more is casting the more intractable or expensive waste streams into a sphereical or dart shape (large) forms and either releasing it to punch into the abyssal plain pelagic ooze or directly down into the convergent margin of a plate (think Marianas trench) where it would eventually be subducted and recycled through the tectonic system (and no, it’s not going to screw anything up. If you took everything ever built or generated by man and put it into a subduction zone the earth wouldn’t even burp from it...)
