This project describes a quick and efficient carbonization technology that converts solid waste into bio-carbon after a few tens of minutes of reaction time. Our work is based on adequate parameters such as temperature, pressure and catalytic heat diffuser. This work emphasized the heat and control of pressure within a packed bed of solid waste . the reaction was complete after 20 min. The solid waste will be transformed into bio-fuel with almost zero waste. The gas obtained is in majority the steam of water.
