..as luck has it, thermochemical gasification, properly done,
will "eat" those dioxins etc in the interface between the
combustion zone and the reduction zone in the charcoal bed.
..now, given the previous historical incineration dioxin disasters,
expect (and budget) to prove it both in theory and in practice.
..chk the recent discussion these last 2 weeks here on "dioxin
formation", starts from my comment on that in: ...
...then from digest-posters (same thread, but broken up by bad mail
client software, a mail list can only guess how to handle these):

..Jai here speaks of biological gasification, which also
works ;o), it's easier to get approved and harder to get
the right germs working right, that again depend on what
kinda people you have engineering this plant, and kinda
staff you can get to run your plant for you.

Scenarios always come in sets of three:
best case, worst case, and just in case.
