  • the heat supply to the material in the degassing channel via the surrounding it Coat is relatively inefficient. Direct heating of the garbage in the Degassing channel can only enter if it is sufficiently dry to to allow partial combustion. Garbage with a moisture content above 30% cannot be processed in this way.
