Entwicklung von abgelagertem Hausmüll aus den 80er Jahren und mechanisch-biologisch behandeltem Restmüll – ein Vergleich
Seit 2004 muss nach österreichischer Deponieverordnung Restmüll vor der Ablagerung einer Behandlung unterzogen werden. Diese kann thermisch (Verbrennung) oder biologisch erfolgen. Ziel der mechanisch-biologischen Behandlung ist die Abtrennung und Verwertung der heizwertreichen Fraktion und die Reduktion von Deponieemissionen durch die biologische Vorbehandlung. Die Ablagerungsfähigkeit wird durch Grenzwerte für die biologische Aktivität unter aeroben und anaeroben Bedingungen und den Brennwert definiert.
Fünf drei Meter tiefe Profile einer Ablagerung von Hausmüll mit einer Zumischung von Klärschlamm aus den 1980er Jahren wurden mit herkömmlichen Parametern, Infrarotspektroskopie und thermischer Analyse charakterisiert. Abhängig von den vorherrschenden Umweltbedingungen, vor allem vom Luftzutritt, entwickelte sich das Material unterschiedlich mit zunehmender Tiefe. Proben aus verschiedenen Tiefenstufen wurden mit heutigem MBA-Material und Material aus einer alten Deponie, die Hausmüll und Baurestmassen enthielt, verglichen. Unterschiede wurden durch infrarotspektroskopische und thermische Analyse sichtbar gemacht. Die Datenauswertung erfolgte mithilfe multivariater statistischer Verfahren. Der Effekt der biologischen Behandlung in Hinblick auf den Zeitrahmen der Stabilisierung wird durch den Vergleich thermoanalytischer Daten der Profil- und der MBA-Proben aus derselben Anlage

DETERMINATION OF PARAMETERS FOR DESCRIPTION OF WATER BALANCE IN LANDFILLS WITH STABILISED MUNICIPAL SOLID WASTES
© IWWG International Waste Working Group (10/2007)
The deposit of untreated waste is forbidden since June 2005 in Germany and since January 2004 in Austria. Wastes for deposit must be pre-treated thermally or mechanical-biologically and have to fulfil the stability criteria of the Waste Storage Ordinance (AbfAblV). Due to the changed waste characteristics in opposite to untreated wastes, high emplacement densities are achievable with pre-treated wastes. Caused by high loads attained by overlaying waste layers on MBT landfills, low hydraulic conductivities could be already ascertained in laboratory and in situ tests.
COUPLED SIMULATION OF MSW LANDFILLS

Since 1997 the collaborative research centre ‘SFB 477 - Life Cycle Assessment of Structures via Innovative Monitoring’ runs at the Technical University of Braunschweig. Within this framework models for both time dependent mechanical behaviour and reactive transport processes have been developed at the Institute for Structural Analysis so far (Krase & Dinkler 2005; Krase & Dinkler 2006; Kindlein et al. 2005; Kindlein et al. 2006, Hanel J. 2001, Ebers- Ernst J., 2001). Experimental data from corresponding projects of SFB 477 enable validation of the governing parameters.
GREENHOUSE GAS BALANCE OF DIFFERENT WASTE MANAGEMENT STRATEGY
© IWWG International Waste Working Group (10/2007)
The well-known principles of the Waste-Hierarchy (Council of European Communities 1991), which lists minimization of waste production as first priority before recycling, and prior to treatment by means of incineration and landfilling has been widely accepted by policy makers and industry experts. However, it is evident that even with growing environmental awareness during the 1990’s and well implemented glass and paper recycling schemes through source segregation in most western countries, we still generate an increasing amount of mixed municipal solid waste (MSW).
PLACEMENT AND COMPACTION OF TREATED MUNICIPAL SOLID WASTE IN MODERN LANDFILLS RESULTS OF GEOTECHNICAL AND HYDRAULIC TESTS AND MONITORING
© IWWG International Waste Working Group (10/2007)
Since June 1st 2005, in Germany, treatment of municipal solid waste (MSW) is required before deposition without any exception. This means either deposition of incineration ashes or mechanically-biologically treated waste (MBP), formerly called mechanically-biologically pretreated waste. Optimum compaction of this residual waste is required after layering. As MBP, in its mechanical behaviour is quite different from conventional MSW, the ASA, the German association of most of the owners and waste management companies as well as local authorities of landfill sites, operated with MBP, initiated large field tests on the Lueneburg landfill site. These in-situ tests were carried out in order to find out the fundamentals for layering and compaction technique and how to achieve best results.
LIFE CYCLE ASSESMENT OF MUNICIPAL SOLID WASTE MANAGEMENT POSSIBILITIES IN ASTURIAS (SPAIN)
© IWWG International Waste Working Group (10/2007)
Municipal Solid Waste (MSW) constitutes a serious problem in urban areas. A waste hierarchy is often suggested and used in waste policy making. Different versions of the hierarchy exist, but in most cases the following order is suggested: 1. Reduce the amount of waste, 2. Reuse, 3. Recycle materials, 4. Incinerate with heat recovery, 5. Landfill. The first priority, to reduce the amount of waste, is generally accepted. However, the remaining waste needs to be taken care of as efficiently as possible. The hierarchy after the top priority is often contested and discussions on waste policy are intense in many countries.
