In Belgium, and I do not see why it would be different in France, in
Germany, in the Netherlands and in Denmark, MSW incinerator bottom ashes
are hauled by using trucks (lorries in UK) to landfills. Fly ashes are
supposed to be neutralized, f.i. by vitrification.

Fly ashes are what comes out of the electrostatic dust filter and, if
present, from the bag filters supposed to depollute the incinerator fumes.

Although they pretend they never do it, some MSW incinerator operators mix
fly ashes and bottom ashes, the mix being dumped as such in landfills. The
result is a substantial decrease in operating costs.

Some countries use bottom ashes in road construction. This practice raises
questions. Bottom ashes are basic, chemically speaking. Rain water is acid.
Acid + base generates salts and water. Salts are then leached through the
ground, sometimes down to the water table. But who can prove the water
pollution comes from thes bottom ashes.

I hope this answers your question. Best regards,
