[Stoves] Stoves Digest, Vol 20, Issue 24

[adkarve]

it is not at all necessary to use wood for making charcoal. We have more
than a 100 kilns operating in India, and the raw material that we use are
just dry leaves, agricultural waste, needles of conifers and paper and
cardboard waste from cities. The process of charring is that of oven and
retort, copied from the process used by Yuri.Therefore the pyrolysis gas is
burned within the kiln itself and it is not allowed to pollute the
atmosphere.
