How do they make lump charcoal?
Lump charcoal is made by taking wood, usually limbs, branches, slabs from lumber mills, scraps from milling operations, etc. and heating this wood in a closed container in the absence of oxygen. Here’s a link to a video that aired on KETC, the public television station in St. Louis: Charcoal Making. Note that this is the same company that was featured in an Episode of “Dirty Jobs” on the Discovery Channel.
