Since November 2014 we have had a fully operational prototype of the "mobile adam-retort"!

Photo 1) The "mobile adam-retort" can be handled by only one person, estimated weight about 140kg (On the right side you see a fixed masonry "adam-retort" which has been in operation since 8 years)

Photo 2) Capacity of 2 wood chambers about 430 litres which can take ~150kg of wet wood, or ~120kg of wood without water, Expected charcoal output about ~35kg per batch. Operation time about 5 hours, cooling occurs over night. This amounts to a daily batch production.

Photo3) It is easy to load wood into the tilted retort (90°)- this actually makes it fun to load the unit....

Photo 3) Burning of wood gas in the external fire box- which starts about after the 3rd hour of wood drying .
We have achieved rather smokeless carbonization, low emissions!

Here we are:  a more environmentally friendly production of charcoal for fuel and biochar !

-Please note
The “mobile adam-retort” is designed for factory fabrication for a significant number of production units.
(The fixed masonry “adam-retort” can be built individually by a mason)

-however the fabrication of such a “mobile adam-retort” made from metal should be crafted by a professional metal worker with a well equipped metal workshop.
So if you are a farmer, a permaculturalist, biochar user, a NGO staff person, don’t come to me and ask for drawings and my advice how to build this retort.      No, please find an individual, an entrepreneur,  who will be interested in manufacturing a whole series of these mobile retorts and who will be willing to be a country's representative.


We still have some issue to achieve smokeless operation and we will test another prototype end of 2018

This "mobile adam-retort" is registered for patent application !    Patent pending, all rights reserved.

We published a youtube video recently:
