Özet
In this thesis, newly developed environmental and social life cycle sustainability assessment methodology was applied on the packaging waste management collection systems, for the first time in Turkey. To the best of our knowledge, many environmental life cycle assessment studies were performed on waste management system modeling. On the contrary, there are only a few social life cycle assessment studies on waste management systems. And, most of these studies mainly focused on the integrated waste management systems. However, each stage of an integrated waste management system involves a different management-operation strategy for itself. To achieve an optimum efficiency in a municipal solid waste management system, it is important to analyze each stage's requirements. In this management process, a well-organized separate collection stage increases the entire systems' efficiency. This thesis consist of a detail analysis of separate-collection of packaging waste in terms of energy and resource consumption. Thus, it is an important application analysis for service suppliers and decision-makers. Applied methodology in this research is a holistic approach which integrates the environmental and social impacts together. Integrated environment and social analysis of the systems, is a significant aspect considering the importance of sustainable life concept. Thus; for the decision makers, the concept of sustainability was also covered and assessed in this study under the two perspective—environment and society, for the first time in Turkey. In the literature, there is not a comprehensive life cycle assessment study on packaging waste management system. Therefore, this study is unique and will contribute to case studies especially on social life cycle assessment of waste management system, considering the insufficient number of the case studies in the literature.
Özet (Çeviri)
Source-separated collection of recyclable packaging wastes has been a huge issue for metropolitan cities such as Istanbul considering their socially, economically, culturally and environmentally cosmopolite structure. In order to provide an environmentally and socially effective separation-collection and recycling application; management system has to be analyzed with a holistic approach including the issues, such as recycled packaging material amounts, source consumptions, related emissions, working conditions, social acceptability and human rights. In the scope of this thesis, existing and alternative municipal packaging waste management systems were analyzed and compared each other in terms of environmental and social impacts. The research was mainly based on a long term site observation, data collection and existing system analysis. After the existing system analysis, alternative scenarios were determined for the research area. Environmental performance of alternative scenarios were calculated in terms of existing system data, whereas more site observations and interviews with social groups were conducted for determination of the social impacts. Both environmental and social impacts of the scenarios were determined by using Life Cycle Assessment methodology. Results of the study showed that informal collection was environmentally more effective than the formal collection systems. Even the resource consumptions were increased, more recycling material collected systems were still environmentally more beneficial. On the other hand, social impact assessment results indicated that informal collection system had social disadvantages compared to formal systems. And finally, it was found that environmental and social weaknesses of the system could be minimized with integrated system applications.
