Pyrolyse-Verfahren zur Restmüllbehandlung in Bayern

The deposition of untreated waste is illegal after the year 2005 on account of the new Technical Instructions for Housing Refuse (Technische Anleitung (TA) Siedlungsabfall). Therefore, the thermal treatment of waste is becoming more important than in the past. The traditionally used grate firing with steam boilers has potential for improvement. The characteristics of the different types of pyrolysis processes are explained and compared using the experience of projects planned, or already realized, in the state of Bavaria. This paper takes credit of the waste pyrolysis plant in Burgau, which is in operation since 1983, and the advanced pyrolysis plants in Fürth (Schwelbrenn-process) and in Ansbach (Thermoselect-process). The conversion-process is another newly developed method of thermal waste treatment. Some information will also be given about the pyrolysis plant for plastics in Ebenhausen. A comparison of the emission of conventional grate firing, and of 2-stage pyrolysis processes with the standards of the German laws for emission (17th BImSchV) shows, that all these processes, if planned correctly, meet the legal standards of emission. It is expected that in the future different thermal processes for waste treatment will prove successful, depending on the task.
