As the population grows and vehicles are increasingly owned, emissions from fossil fuels are worsening environmental problems. In this context, electric vehicles (EVs) present a significant alternative for the development of sustainable transportation systems. However, for electric vehicles (EVs) to become a prevalent form of transportation, the establishment of an effective and efficient charging infrastructure is imperative. The primary objective of this study is to ascertain the most suitable location for the installation of an electric vehicle (EV) charging station within the Erzincan Binali Y & imath;ld & imath;r & imath;m University Yaln & imath;zbag Campus. During site selection, the analytical hierarchy process (AHP) and TOPSIS methods were used to evaluate the criteria. The study was conducted in two stages. In the first, seven active-use transformers on campus were weighed using the AHP method, then the most suitable one was selected using the TOPSIS method.In the second, seven parking areas were analysed using the same criteria. The parking lot selection used the AHP and TOPSIS methods, considering faculty and campus entrance distance, lot capacity and transformer preference score. The findings of the study demonstrate the efficacy of the AHP and TOPSIS methods in the context of multi-criteria and multi-stage decision-making processes. The integration of these methods has been demonstrated to facilitate the optimisation of EV charging station location selection, both in technical and practical terms.

The food industry constantly growing with increasing population and food diversity. In addition to production, the formation of food waste is also increasing. These wastes cause environmental pollution, economical problems and the loss of valuable chemical com-ponents. Tomato is used for tomato paste, sauce and other food production; especially the skin and seed part of tomato is waste. Grapefruit and quince have a significant amount of waste, especially in the beverage industry. The reuse of these wastes can reduce the exposu-re of solid waste, the environmental problem and the recovery of the bioactive components. In this study, some physicochemical, functional and thermal properties of quince, grapef-ruit and tomato waste were determined and their reuse potential was revealed. All three samples showed high hydration properties. According to the dietary fiber analysis, TDF of quince, grapefruit and tomato were 87.90%, 90.34%, and 63.76% respectively. DTG and TGA chromatograms were obtained for the thermal decomposition of the samples. Tomato waste signaled lycopene and its derivatives as distinct from the other samples in the FT-IR spectrum. Based on the results of the study; the use of these wastes in many food products as hydrocolloid, filler, fat replacer is possible, also cost reduction may be possible with the recovery of these samples.
