ABSTRACT:
A method for producing a solid fuel from combustible waste includes sorting and grinding the waste, treating the waste by heating in the absence of oxygen in a first pyrolysis reactor and then collecting the waste so treated. Polluting elements in the gases emerging from the pyrolysis are removed while the gases are hot before being directly reused to heat a first pyrolysis reactor so that solids leaving the pyrolysis operation provide a fuel without the pollutants initially contained in the waste. The device for carrying out this method includes a pyrolysis reactor and a unit for supplying an absorbent to a zone wherein the gases generated by pyrolysis are contacted by the absorbent to remove the polluting elements; the absorbent and the decontaminated solids are separated from each other.
