The charcoal production technology developed by Bricarbras a Hübner Group Company is the state of art in clean charcoal manufacturing. Charcoal is a important raw material for the steel and pig iron production. The old pollutant brick kilns give place for a new clean technology that uses trained personal, and provides higher efficiency in the conversion of wood into charcoal. With Bricarbras technology the charcoal production has no environmental impact because it's a clean process.

The carbonization kiln with vertical metal cylinders consisting of a semicontinuos charcoal production system. The charcoal production unit (CUP), to produce 3000 m3 of charcoal per month comprehends:

• 8 kilns;

• 3 metal cylinders per kiln, totalizing 24 per CUP;

• 24 grades cast in special alloys, with an internal chimney (1 for each cylinder)

• 1 smoke incinerator;

• 1 firewood dryer.

The polluting smoke generated during carbonization is taken to a smoke incinetator, an equipament responsible for both feeding the firewood dryer with hot air and thermally destroy toxic substances including methane, one of the global heating agents without impacting the environment.

The firewood dryer is an authetic innovation without similar in the market. Besides using the hot gases from the smoke incinerator, the dryel is fitted with a microwave emitter positioned on the dryer wall. With the Bricarbras system it is possible to dry 250m³ stereo batches os firewoor in times from 30 to 48 hours.
