Charcoal Retorts | Efficient Charcoal Production
The retort system offers high charcoal productivity and is a more efficient way of scaling up charcoal production. By clever design and using the wood's natural gases to reheat the retorts our charcoal system boasts significant advantages over the more traditional ring style charcoal kilns and offers: More efficient use of raw materials.

Small Scale Biochar | Nebraska Forest Service
Loggers, forestry contractors. Anyone interested in producing biochar for small, niche markets such as farmers markets. Example: Assuming a biochar recovery rate of 33%, a 55-gallon drum retort kiln would yield ~2.5 cubic feet of biochar per batch. One cubic foot of biochar retails between $30 and $60.
Charcoal: A discussion on carbonization kilns
The main masonry or brick carbonization kilns are: "Hot-tail" kiln, Slope type kiln, Surface kiln, JG® Surface kiln, Masonry rectangular kiln, MF1-UFV kiln, Adam-Retort, Missouri kiln, and Argentine kiln. The "hot-tail" is the main kiln used in Brazil. This kiln is made of masonry (bricks laid with clay) and is small-sized [59].

The results indicated that weight of charcoal increased 7.38 % whereas the weight of ashes decreased 18 % at the flue was installed within charcoal retort kilns. Moreover, the gas exhaust from process at the flue was installed inside charcoal retort kilns less than the gas exhaust at the flue was installed outside charcoal retort kilns.
Earth mound kiln
1 kg of insufficiently burned wood (smouldering) is polluting about 700m³ of the atmosphere. About 17 million tons of wood are needed to produce these 3 million tons of charcoal, if the charcoal is produced with this ancient earth-mount-kiln technology. About 11.900.000.000m³ air is polluted per year by this old method in these 2 countries alone!
