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.
