Article Citation - WoS: 1Life Cycle Assessment of Tomato Paste Production: a Case Study(Pamukkale Unıv, 2024) Üçtuğ, Fehmi Görkem; Tekin, Zehranur; Dayıoglugil, Zeynep; Ulusoy, Ercan; Oktaylar Keyik, Şule; Keyik, Sule OktaylarThis study involves the cradle -to -gate life cycle assessment of tomato paste production in Turkey. All the data was obtained from a large-scale production company located in north-west Turkey in 2020. CCaLC software with Ecoinvent2 database alongside CML2001 method was used for the analysis and the following impacts were taken into account: acidification potential, carbon footprint, eutrophication potential, human toxicity potential, ozone layer depletion potential, and photochemical smog potential. Functional unit was chosen as 1 kg of tomato paste sold in glass jars. The results show that the biggest contributor to environmental impacts was the raw material supply stage, mainly due to fungicide (for agriculture) and metal (for packaging) use. Energy required for agricultural and production processes were also found to have significant effects of the impacts. The results were found to be in very good consistency with earlier literature. Using photovoltaic panels for meeting 10% of the electricity demand of agricultural and production processes or utilizing tomato harvesting waste to produce biomethane were found to have almost no positive effects as far as impact reduction is concerned. These results show that switching to organic farming seems to be essential if environmental impacts of processed food products such as tomato paste are to be reduced.Article Promoting Utilization of Biofuels in the Transportation Sector To Reduce Co2 Emissions: Comparative Analysis(Gazi Univ, 2022-12-16) Bozbay, Utku; Güngörmüşler, MineIn this study, due to the high contribution of the transportation sector to generate CO2 emissions, an evaluation for the best scenario of the replacement of petroleum derived fuels by renewable and sustainable alternatives was assessed with a multi collative approach suggesting the second-generation bioethanol as the most promising one. In this context, this paper focused on the practices over the past 23 years in the following four countries; Turkey, China, Sweden, and Brazil, with a comparative regression analysis between the CO2 emissions generated from the consumptions of total energy and biofuels. Accordingly, a curve-fitting and an estimation on the formation of CO2 emissions with the incrementing blends of gasoline by 3 to 100% of bioethanol was forecasted for 2020 to 2030. The outcomes of the comprehensive research indicated the international and national benefits of biofuel use, thus, promoting the potential integration of bioethanol in the Turkish transportation sector.
