Abfallentsorgungsplanung - Beeinflussung der Umweltauswirkungen von Deponien

Subject of this study are the environmental impacts of landfills for municipal solid waste and the possibilities to influence them by means of waste management and site planning. This approach reflects upon the multibarrier concept, as it is fixed in the German technical regulations for municipal solid waste, the 'Technische Anleitung Siedlungsabfall (TASi)'. According to this concept, three independent barriers shall reduce the environmental impacts of the landfill: the election of (hydro-) geologically qualified sites, technical means like containments, and - last not least - the pretreatment of the waste itself. These barriers and their interaction are discussed emphasizing the planning phases 'solid waste management concept' and 'site election'. In chapter 2, a qualitative enumeration of environmental impacts as well as the affected environmental compartments is given, with emphasis on the interaction between compartments. Following, the environmental impacts and the possibilities to influence them by means of waste pretreatment are analysed. This would be incomplete without taking the impacts from pretreatment plants into account; these latter are discussed by evaluation of 'comparison studies' (chapter 3). Quantitative accounts on landfill emissions and other impacts under the conditions of thermal resp. mechanical-biological pretreatment are given in chapter 4. The next two chapters deal with the impacts on the local environment and the possibilities to influence them by means of the site selection. Chapter 5 gives an overview on the selection process for a landfill site in the German region Ostholstein. Chapter 6 describes for each environmental compartment the resulting conflicts, methods for investigation and analysis as well as standards of value, and assesses the results. In the final chapter 7, the results are reflected focussing the TASi standards. The conclusion is, that some of these standards are not adequate; suggestions are given for more appropriate, environmentally sound landfill concepts.
