Article Citation - WoS: 29Citation - Scopus: 32Wind Farm Site Selection Using GIS-Based Multicriteria Analysis With Life Cycle Assessment Integration(Springer Heidelberg, 2024-01-19) Demir, Abdullah; Dincer, Ali Ersin; Ciftci, Cihan; Gulcimen, Sedat; Uzal, Nigmet; Yilmaz, KutayThe sustainability of wind power plants depends on the selection of suitable installation locations, which should consider not only economic and technical factors including manufacturing and raw materials, but also issues pertaining to the environment. In the present study, a novel methodology is proposed to determine the suitable locations for wind turbine farms by analyzing from the environmental perspective. In the methodology, the life cycle assessment (LCA) of wind turbines is incorporated into the decision process. The criteria are ranked using analytical hierarchy process (AHP). The study area is chosen as the western region of Turkiye. The obtained suitability map reveals that wind speed is not the sole criterion for selecting a site for wind turbine farms; other factors, such as bird migration paths, distance from urban areas and land use, are also crucial. The results also reveal that constructing wind power plants in the vicinity of Izmir, canakkale, Istanbul, and Balikesir in Turkiye can lead to a reduction in emissions. Izmir and its surrounding area show the best environmental performance with the lowest CO2 per kilowatt-hour (7.14 g CO2 eq/kWh), to install a wind turbine due to its proximity to the harbor and steel factory across the study area. canakkale and the northwest region of Turkiye, despite having high wind speeds, are less environmentally favorable than Izmir, Balikesir, and Istanbul. The findings of LCA reveal that the nacelle and rotor components of the wind turbine contribute significantly (43-97%) to the environmental impact categories studied, while the tower component (0-36%) also has an impact.Article Citation - WoS: 18Citation - Scopus: 18Efficient Disaster Waste Management: Identifying Suitable Temporary Sites Using an Emission-Aware Approach After the Kahramanmaras Earthquakes(Springer, 2023-07-31) Demir, A.; Dincer, A. E.The clean and sustainable disposal of waste generated by natural disasters is crucial for effective disaster waste management. The initial stages of waste management involve determining the quantity of waste and identifying suitable temporary sites for its disposal. This study estimates that the Kahramanmaras province produced approximately 15 million tons of construction and demolition waste and 41,000 tons of household waste following the recent Kahramanmaras Earthquakes on February 6, 2023. Additionally, the study proposes eight temporary disaster waste sites considering various environmental and technical criteria. It should be noted that this is the first study to factor in emissions from waste transportation when selecting temporary disaster waste sites. An algorithm that considers the transportation network to calculate emissions for each map pixel is developed and integrated with geographic information system to identify the best temporary disaster sites. The results show that the most suitable location for temporary sites is southeast of the city center. The transportation time of the waste to the most suitable temporary site is found to be 98 days when 1000 trucks are in operation. The estimated emissions due to the transportation of the waste to the recycling facilities in this region are approximately 88,000 tons of carbon dioxide, 4.4 tons of sulphur oxide, 7.6 tons of nitrogen oxide, and 47.7 tons of particulate matter. The approach employed in this study can be utilized to identify suitable temporary sites for waste management after any natural disaster.
