To produce 1 ton of charcoal, 6 tonnes of wood are required.
The charcoal comes from the partial combustion of natural wood, in a closed environment and without air or oxygen.
The combustion allows to evict the water and the tar of the wood and to keep a maximum of pure carbon in order to obtain a constant and a quick cooking time of the food.
At the end, the charcoal is carrying by conveyors to be dusted and graded. Then, there is a sorting between :
- Chunks for restauration quality
- Means pieces for high quality
- Fine coal (dust) for briquettes
The fumes during the carbonization are destroyed by incineration.
