A nice article on making charcoal from waste.
although I still think the gold standard is pyrolysis as it uses the energy released by the process and reduces airborne toxins considerably.

Charcoal making
Traditionally, charcoal is made from forest wood cut into pieces and partially burnt. However, charcoal can be made from agricultural residues such as stems and twigs that would otherwise be left in the field and burnt away as waste. Some of the common crops whose stems are suitable for charcoal making are soyabean and red gram.
Any kind of wood can be used to make charcoal. However, if softwood is used, it will make soft charcoal and therefore burn more quickly. Also, the method used for softwood would not be applicable for hard wood as the latter is denser and tends to burn slowly.

As I remember, the Amazonian Indians used hardwood.
I wonder if this makes a diffence to TP?
