- •
Fly ash from municipal solid waste incineration has a high trace element content.
- •
Cd, Pb, and Zn are primarily associated with carbonates and mobile under acid pH.
- •
Microbial treatment promotes the cementation and stabilization of fly ash.
- •
The treatment enhances the leachability of metals.
- •
It can be applied to recover metals of economic interest.
