    Industrial Symbiosis Model as a Tool of Circular Economy Supported by Lca: a Case Study of Adana Organized Industrial Zone
    (01. Izmir Institute of Technology, 2024) Küçüker, Mehmet Ali; Küçüker, Mehmet Ali; Küçüker, Mehmet Ali; 03.07. Department of Environmental Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    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.

    Hybrid Renewable Energy Systems Design for Green Campus-Iztech
    (01. Izmir Institute of Technology, 2022) Çağlar, Başar; Çağlar, Başar; Açıkkalp, Emin; 03.06. Department of Energy Systems Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    This study focuses on evaluating of standalone PV and Wind systems integrated with energy storage technologies to meet the electricity needs of the Izmir Institute of Technology campus in Izmir. University campuses with their high energy demand are one of the most important application areas for renewable energy systems and it’s critical to determine the types of renewable energy technologies, their size, and techno-economic feasibility for possible future implementation. Solar and wind energy were chosen as renewable energy sources based on the location and renewable energy potential of the IZTECH Campus. Two different energy storage systems are proposed to prevent any loss of power supply in standalone mode: (i) Lead-acid battery and (ii) Electrolyzer, hydrogen storage tank, and hydrogen-powered generator. Models were developed using the dynamic library-based structure of the TRNSYS program. The hourly electrical load was generated based on monthly data taken from the electricity supplier and the power output of PV modules was calculated based on the fixed tilt angle based on real meteorological data for the campus location. The electricity demand and generation were analyzed hourly for one calendar year. The number of PV modules was determined to meet the annual electricity demand of the campus while the capacity and number of energy storage modules were determined based on the maximum accumulative energy deficiency in a year. The round-trip efficiencies and the depth of discharge for the battery and the hydrogen storage efficiency for the hydrogen-based storage option were considered in the analysis. Parameters were calculated for both systems and simulation analyzes were evaluated. An economic cost analysis was performed for each system. In addition, suggestions are made for possible system improvements.

    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.

    Participatory Planning Support System for Assessment of Spatial Conflicts in Izmir Peninsula
    (Izmir Institute of Technology, 2014) Yazdani, Hamidreza; Saygin, Mustafa Ömür; 01. Izmir Institute of Technology
    Development strategies and their possible impacts over time as a consequences of proposed spatial development are one of the main concerns of planners in planning process. Understanding the impact of these changes on environment and balanced management to distribute resources are essential indicators for planning approach aiming to achieve the sustainable development. A precise, accurate and up-to-date data in addition to reliable spatial analysis are basic requirements of sustainable decision making. A Planning support system (PSS) is mainly based on collecting, monitoring, analyzing data and evaluating the impacts of alternative planning scenarios using Geographical Information Systems (GIS) for contributing spatial decisions. This study offers an approach to evaluate possible conflicts between development strategies in an environmentally sensitive areas. The approach is based on a PSS which integrated collaboratively weighted scenarios and natural assets. The study identify a framework for Co-production of data, evaluation of model outcomes and ranking natural and regional assets in cooperation of interest groups by utilizing Delphi survey in a conflict model of Esri ArcGIS. This model reveals impact level of development strategies on environmentally sensitive area and geographically map the conflicts of these strategies on each other and nature. The outcomes of model assist decision makers to produce alternative approaches for sensitive areas where conflicts of different polices are inevitable. Additionally the model utilize public participation in both gathering data and evaluating spatial analysis. This lead to a more adoptable planning practice where planners reach to public knowledge about region and guaranty guaranty consensuses in spatial decision making.
