[Gasification] Ash to land?

[Pels, J.R. (Jan)]

I would say so. When you make charcoal and burn it elsewhere, then
dispose the ash safely. 

Depending on the temperature you make or lose active groups that can
bind metals. Char made at high temperature does not bind metal very
well. pH is also critical for heavy metal mobility.
