Technical Development of Waste Sector in Sweden: Survey and LifeCycle Environmental Assessment of Emerging Technologies
Waste can be considered as an urban burden or as a valuable resource depending on how it ismanaged. Different waste treatment technologies are available at present to manage municipal solidwaste (MSW). Various actors are involved to develop waste treatment technology for certain area.The aim of this study is to analyze the driving forces in technical development in waste sector inSweden. The study is also done to identify emerging waste management technology in Sweden.Moreover, a comparative study of existing and emerging technologies is done by Life CycleAssessment (LCA) model. An extensive literature review and pilot questionnaire survey among thewaste management professionals’ is done for the study. LCA model is developed by SimaProsoftware CML2 baseline method is used for identifying environmental burden from the wastetechnologies.Dry composting, Pyrolysis-Gasification (P-G), Plasma-Arc are identified as potential emergingtechnologies for waste management system in Sweden. Technical developments of thesetechnologies are influenced by indigenous people’s behavior, waste characteristics, regulations, healthor environmental impact and global climate change. Comparative LCA model of P-G andIncineration shows that, P-G is a favorable waste treatment technology than Incineration for MSW,especially in acidification, global warming and aquatic eco-toxicity impact categories.
