transporting a fuel mix comprising liquid and
solid residual materials, separately to the rotary
drum kiln;
burning the fuel mix in a flame, for forming
active carbon;
burning the feed in the flame at a temperature of
over 700°C, for forming CaO and flue gases;
calcining the CaO at a temperature of over
1,200°C in the presence of SiO2 [sic], Al2O3 [sic],
