Initially, the CHARTHERM^TM process was developed to solve the problem of wood treated with CCA (Chromium/Copper/Arsenic). Today, CHARTHERM^TM is the only process in the World to have been developed on an industrial scale that can be used to deal with problems associated with recycling wood treated with CCA, or any other type of polluted wood.

Thereafter, the CHARTHERM^TM process was being developed and optimised, it was revealed that the clean Carbon powders, the CARMATH^TM and the CORBAN^TM, produced during this process, had very specific properties.

The CARMATH^TM and the CORBAN^TM are raw materials that can be used for numerous applications without undergoing transformation (filtration, purification, molecular sieve, anti-static shielding,...).

Thus, the CARBSTYL^TM process, derived from the CHARTHERM^TM process, can be used to produce Carbon powders from different types of organic solids such as wood, of course, but also viscose, bagasse, chicken litter and other biomass, including tyres.

The CARBSTYL^TM process consists of three main steps:

• The first step consists in preparing the raw material. In the case of wood, this involves grinding. The purpose of this conditioning process is to break down the raw material so that the size and texture of the broken-down parts optimise the thermal stage of the process.

• The second step, “Chartherisation”, is the most important part of the process. Chartherisation constitutes the thermal stage of the process during which the wood is distilled.

• The carbonaceous product obtained at the end of the Chartherisation process, collected at the bottom of the column, is treated to be able to extract the final Carbon powder, otherwise known as CARMATH^TM or CORBAN^TM. The refining involves a grinding stage and a separation phase.
