In the weekly seminars of the Environmental Engineering Department of Hacettepe University, the latest session featured presentations by two Ph.D. students from the department, Özgenaz Dayar and Gülşah Akgül, each addressing critical environmental topics.

In the first part of the seminar, Özgenaz Dayar, an experienced environmental engineer and consultant, presented on the "Polyethylene Terephthalate (PET) Lifecycle Analysis for Sustainability in the Textile Industry." Her presentation covered the environmental impact of PET use in textiles, analyzing its production, usage, and recycling processes. She discussed sustainability strategies aimed at reducing PET-related waste and promoting circular economy practices. Through lifecycle assessment methodologies, she highlighted how informed decision-making in PET usage could contribute to sustainable textile production, ultimately aligning with global environmental goals.

In the second part of the seminar, "Modeling the Future of Secondary Aerosols in the Eastern Mediterranean," Gülşah Akgül, an environmental engineer and atmospheric researcher, explored air quality modeling techniques to predict secondary aerosol formation and distribution patterns. Her presentation detailed how these aerosols influence regional air pollution and climate dynamics, with a particular focus on transboundary pollution effects in the Eastern Mediterranean. She explained the integration of computational models with observational data to project future trends, emphasizing the importance of proactive measures in air quality management.

Both presentations contributed valuable insights to ongoing discussions on environmental sustainability and atmospheric research, demonstrating the department’s commitment to tackling real-world environmental challenges through scientific inquiry
