    This thesis aims to develop an industrial symbiosis model for 24 facilities located in the Adana Organized Industrial Zone (AOSB). Within the framework of the European Union Green Deal (EU Green Deal) and the United Nations (UN) Sustainable Development Goals, which emphasize the global importance of the circular economy (CE) model, this thesis focuses on all aspects of industrial symbiosis to transform organized industrial zones into eco-industrial parks and promote greener and more sustainable production. All facilities have been coded with NACE codes, and potential symbiosis alternatives between them and within in-factory processes have been examined. Potential matches have been identified and evaluated based on criteria such as environmental gains, emission reductions, and decreases in electricity, natural gas, and waste production that could be achieved through symbiosis. Value stream maps have been prepared for all facilities, and tables summarizing production and consumption processes have been created. Potential matches with other facilities have been identified, and a visual network was created through network analysis. Life cycle analyses (LCA) were conducted for two facilities, assessing the potential benefits of symbiosis through LCA. Subsequently, environmental benefits of symbiosis were calculated using emission factors. This study reveals that, as a result of possible industrial symbiosis scenarios, an industrial symbiosis system formed by the companies subject to the thesis could potentially achieve approximately 120,000 tCO2 emission savings and 15,000 MWh electricity savings annually. This study will contribute to future industrial symbiosis efforts in the transformation process of an organized industrial zone into an eco-industrial park.

    Evaluation of Waste Management System in İzmir-Karaburun Peninsula From Sustainability Perspective
    (Izmir Institute of Technology, 2022) Hajatnia, Haniyeh; Ökten, Hatice Eser; Ökten, Hatice Eser; 03.07. Department of Environmental Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Global solid waste generation is constantly rising, hence the need for management strategies that implement environmental improvements. The sustainable municipal solid waste management strategy for municipalities must include collection and transportation. The collection and transportation sector have been neglected while it is one of the most significant polluters. As a result, this study aims to model municipal solid waste transportation using Life Cycle Assessment (LCA) software which we used CCalC2 for this study and CML2001 methodology was used. To demonstrate how different approaches to waste management through transportation can reduce environmental impacts, LCA modeling was done for the three districts of Urla, Çeşme, and Karaburun, all of which are located on the Karaburun Peninsula. Each district was assigned three scenarios, with Scenario 0 representing current municipal practices, Scenario 1 representing a 50% reduction in plastic waste, and Scenario 2 representing a 50% reduction in all renewables. Results showed that only plastic separation might not be enough to achieve significant e reductions in environmental impacts. It has been demonstrated that in the transportation sector of Urla and Çeşme, Scenario 1 had a CO2 reduction of 3.7% and Karaburun had a CO2 reduction of 3.8% while Scenario 2 represented at least a 20% reduction of carbon footprint in all three districts. Findings of this research will support municipalities in the roadmaps they will choose for the Municipal Solid Waste Management applications.
