[Terrapreta] commercial charcaol.

[Tom Miles]

Michael,

I understand that there are circumstances in the US where non-biomass
materials such as bitumen can be used in briquettes for fuel use. I don't
requirement for these companies to disclose ingredients below a certain
level, or whether they have be tested. I have not seen any test data of
commercial briquettes that would show this kind of composition. Most of the
cautions Ihaveseen about using commercial briquettes had to do with the high
alkalinity of barbecue ash.

While in Korea last Fall I noticed an article in the paper that reported on
high levels of heavy metals in charcoal fuel briquettes made from refuse.

Can anyone advise does regular commercial charcoal such as 
Kingsford have any particularly nasty materials in it as binders 
or anything or is it acceptable to add to soil as well.

Thank you,
