Abstract

To decontaminate old rubbish dumps, the extracted material is heated so that the organic fraction is reduced to a residue with a carbon content value of less than 5%. The thermal energy is provided by combustion of the gas generated by the rubbish dump and/or by dumping new rubbish.

Description

In der Abfallwirtschaft herrscht ein katastrophaler Notstand in Bezug auf die Errichtung neuer Anlagen, weil die Genehmi­ gungsverfahren meist mehr als 10 Jahre dauern.There is a catastrophic emergency in waste management with regard to the construction of new plants because the approvals procedures usually take more than 10 years.

Unter diesem Druck ist man auf den Gedanken gekommen, alte Abfall-Deponien "umzuschichten", - indem man den Deponieaus­ hub derart mittels zerkleinern, rotten, pressen oder derglei­ chen bearbeitet, daß das Material bei der erneuten Ablagerung weniger Raum einnimmt, so daß die alte Deponie durch Platz für neue Abfälle eine verlängerte Lebensdauer erhält.This pressure has given you the idea, old man "Reallocate" waste landfills - by leaving the landfills stroke by means of shredding, rotting, pressing or the like Chen processed that the material when redeposited occupies less space, so the old landfill by space extended lifespan for new waste.

Mit diesen Maßnahmen erreicht man jedoch bestenfalls eine Volumenverringerung für den Deponieaushub um 20 bis 30%. Die meisten heute betriebenen Abfalldeponien sind jedoch bereits fast völlig aufgefüllt oder gar überfüllt, so daß der beschriebene Notstand kaum um den Zeitraum verlängert werden kann, den Genehmigungsverfahren für neue Deponiestand­ orte oder Verbrennungsanlagen erfordern.With these measures, however, one can at best achieve one Volume reduction for the landfill excavation by 20 to 30%. Most landfills operated today, however, are already almost completely filled or even overcrowded, so that the described emergency was hardly extended by the period can be the approval process for new landfill sites locations or incinerators.

Aufgabe der Erfindung ist es deshalb, das Volumen des Deponie­ aushubes so wirksam zu verringern, daß möglichst für mehrere Jahrzehnte die alten Deponien weiter betrieben werden kön­ nen.The object of the invention is therefore the volume of the landfill to reduce excavation so effectively that possible for several Decades the old landfills can continue to be operated nen.

Die Lösung dieser Aufgabe ist nur durch thermische Behand­ lung des Deponieaushubs, - wie in den Patentansprüchen be­ schieben, möglich.This problem can only be solved by thermal treatment development of the landfill excavation, - as in the claims push, possible.

Die Vorteile des erfindungsgemäßen Verfahrens liegen nicht nur in der Lösung der Aufgabe, der Beseitigung des genannten Notstandes. Sie liegen auch darin, daß alle alten Abfallde­ ponien nach der Behandlung den gesetzlichen Bestimmungen des Abfallwirtschaftsgesetzes entsprechen würden und keine umweltbelastenden "Altlasten" für unsere Nachkommen mehr wären.The advantages of the method according to the invention are not only in solving the task, eliminating the above Emergency. They also lie in the fact that all old waste ends ponia after treatment the legal provisions would comply with the Waste Management Act and none more polluting "legacy" for our descendants would be.
