WTE Residue

[envs]

How viable is separation of waste at source to avoid generation of toxic/hazardous residue from a WTE plant?

What are the common (safe?) uses of fly ash and bottom ash from an MSW-fired incinerator?


Is the control of solid waste by the WTE method (together with good recycling measures, before the waste is sent to the plant) considered a sustainable measure?
If yes, good. If not, how can it be made sustainable? What measures have to be taken?

Thank you!

I think it is very viable. Each waste generated can be evaluated through a hazardous waste determination program.
In the USA we follow USEPA regulations 40 CFR 260, 261, 262.
Program can be question and answer steps following the subparts of the regulations. I would add an extra step to determine if any products of combustion would be hazardous. You can hired a hazardous waste services contractor. They can put together a proposal to evaluate the wastes for WTE.

Fly ash and bottom ash from a WTE plant. Can't help you there. Coal ash can be recycled to a concrete plant. Maybe that helps.

What are you looking to get? Acceptable return, energy to waste ratio?
