How do you make coconut shell charcoal?

Answer 1

Answer 1: heat it in a metal container, till it stops smoking, and turns black,

or set it on fire and let it burn for a while.

Answer 2: I guess you seek a cheap way to make active carbon. At least I tried to answer that question for myself. I found out: Carbonization of coconut shell is an industrial process, don't try this at home. All kinds of poisons are created burning the coconut shell in the wrong way. You don't want plain ash, it has to be carbonized, not burned, but then there's a danger you inhale CO gas. When the active coal is used for filtering you better be sure there is no poison residue, my guess is you can't.
