ABSTRACT:
A method and apparatus for treating mixed waste by pyrolysis. Organic mass is carbonized by heating to carbon in a pyrolysis reactor (3) in an oxygen-free environment. Pyrolysis gases are distilled for oil and the gases are used for energy production. Solid matter resulting from pyrolysis is sieved for separating inorganic coarse particles from a carbon fraction. The carbon fraction is milled in two operations, first with a roller mill (8) and then with a jet mill (10), a removal of metal being performed between the operations. The pulverized carbon fraction is classified by means of ionizing particle separators (11, 12, 13). The multi-stage particle separation is followed by discharging clean air and recovering fine carbon.
