What about heavy metals? I've been very interested in gasification of
biosolids (locally you can get paid to take them *and* free delivery, all nice
and dry) and the question of heavy metals immediately arose. I'd think that MSW
would also contain a fair amount of heavy metals, perhaps even more. Of course,
if so, one might look at it as a way of concentrating them if they aren't
destroyed or chemically nullified, possibly a resource for recycling?
