The disposal of waste materials in an environmentally acceptable manner is a great problem needing to be solved with increasing urgency. A known treatment is thermal utilisation, in which the waste materials are burned (incinerated) or else first subjected to low-temperature pyrolysis and the resulting low-temperature pyrolysis products are then at least partially burned. Starting from these known processes, it is proposed according to the invention to carry out the low-temperature pyrolysis in a rotary tubular furnace which contains an immersion bed of prepared low-temperature pyrolysis residues into which bed the waste materials are immersed, which enables direct heating of the rotary tubular furnace. The low-temperature pyrolysis residues obtained in the low-temperature pyrolysis, after mechanical treatment, are then converted into a synthesis gas. <IMAGE> |
