A process and a business method for converting wood waste to charcoal have been invented. Multiple high productive thermo energy simplified bio-cokes furnaces create an outlet discharging the earned volatile gas and the wood tar from the carbonization device. By taking back the gas and the wood tar mixed with the air into the furnace, the present invention produces evenly distributed heat with higher energy productivity. The present invention adopts different Coefficients of Thermal Expansion (CTE) for the top opening zone and the carbonization chamber, to avoid transmittal of oxygen from outside the furnace. Charcoal produced with a reduced energy use by the present invention can replace bio-cokes produced from general waste incineration. Through the creation of higher carbon charcoal, the present invention introduces a source of environment-friendly, cost effective and sustainable heat use. Accordingly, the present invention proposes promising business models both to the suppliers and the consumers.
