As such, biochar is a low-cost and environment-friendly material that can be used as ...
Occurrence and load of micropollutants discharged from urban and industrial wastewater treatment plants to receiving environment in the Yeşilırmak Basin İnce, İrem; Yetiş, Ülkü; Department of Environmental Engineering (2021-8-27) The occurrence of micropollutants in the aquatic environment is an emerging topic. It is known that the wastewater treatment plants (WWTPs) are the main point sources of the micropollutants. With this regard, the purpose o...
Transportation and recycling effects on the household textile waste of Eskisehir using LCA Sipahi, İlayda; Kurt, Zöhre; Department of Environmental Engineering (2021-8-16) Textile is a material that could be diversified the most, therefore considerations of textile waste recycling/ reuse and the effects of its landfill should be carefully considered. In this thesis, transportation and recy...
Assessing the potential benefits from the application of best available techniques in the textile industry Gülveren, Merve; Yetiş, Ülkü; Department of Environmental Engineering (2021-7) The Integrated Pollution Prevention and Control (IPPC) Directive, which was recasted as the Industrial Emission Directive (IED) in 2010, is the main EU’s legal instrument regulating pollutant emissions from industrial esta...
SERICIN PROTEIN RECOVERY FROM SILK DEGUMMING WASTEWATER IN PILOT SCALE VIA MEMBRANE HYBRID PROCESSES Gençtürk, Merve; Yetiş, Ülkü; Çapar, Gökşen; Department of Environmental Engineering (2021-5-17) The conventional degumming method that consists of alkaline washing of silk yarn with Marseille soap at high temperatures, dissolves sericin protein into the water and produces so-called silk degumming wastewater (SDW) whi...
Evaluation of the water-food nexus with the focus on agricultural water management in the Upper Sakarya watershed Özel, Beyza; Alp, Emre; Department of Environmental Engineering (2021-5-15) This study investigates the tradeoffs between water and food (agriculture) nexus and evaluates alternative scenarios focusing on sustainable water governance for agricultural production in Upper Sakarya Basin. For this pur...
Assessment of the Hydrological Alterations and Environmental Flows in Sakarya Watershed, Turkey Özcan, Cansu; Alp, Emre; Department of Environmental Engineering (2021-5) In this study, a holistic environmental flow assessment (EFA) adopted from the ELOHA framework is performed for the Sakarya Watershed. The most significant environmental flow events were quantified using natural streamflow...
Chemical Alternatives Assessment for Substitution of Hazardous Chemicals with Safer Alternatives Rahim, Danial; İmamoğlu, İpek; Department of Environmental Engineering (2021-5) Consumer demand for safer chemicals has given rise to chemical alternatives assessment (CAA) to enable informed substitution of hazardous chemicals. The aim of this thesis was to evaluate alternatives for five hazardous ch...
Pestrans: a software developed for assessing the fate and transport of pesticides in soil environment Alshahethi, Aiman Mohammed Qaid; Ünlü, Kahraman; Department of Environmental Engineering (2021-2-15) Excessive and uncontrolled use of plant protection products in Turkey caused major concerns as many pesticides proved to possess hazardous impact on soil and groundwater systems. The main objective of this thesis is to dev...
