Dr. K. P. P. Udayagee is an environmental engineer and researcher committed to sustainable development, specializing in clean water, sanitation, and the circular economy. She holds advanced degrees in Civil and Environmental Engineering and Agricultural and Biosystems. Dr. Udayagee’s work emphasizes developing sustainable solutions for environmental remediation, waste management, and resource efficiency. She is particularly focused on creating circular systems that enhance sustainability through innovative waste management methods. As a Senior Lecturer, she incorporates these principles into her teaching and research at the University of Sri Jayewardenepura, while supporting global sustainability initiatives.  

Research Keywords: Waste Management and Circular Economy, Industrial Symbiosis, Water Quality, Carbon Sequestration, Environmental Monitoring and Remediation

Advancing sustainable waste management and promoting industrial symbiosis through resource-efficient practices have gained significant attention in addressing environmental challenges. The generation of industrial waste and its improper disposal pose serious threats to both the environment and the economy, particularly as resource demands grow with increasing industrial activity. In recent years, there has been a growing emphasis on reducing waste by identifying opportunities where by-products from one industry can serve as valuable resources for another, promoting resource efficiency and minimizing waste. Dr. Udayagee’s research is dedicated to creating novel, eco-friendly products from industrial waste streams, contributing to the circular economy. Her work integrates industrial symbiosis approaches, focusing on how industries can share resources, reduce waste, and increase resource recovery. By fostering these connections between industries, her research not only addresses waste management challenges but also promotes economic benefits by converting waste into valuable products. Additionally, Dr. Udayagee’s work encompasses environmental monitoring, evaluation, and mitigation to ensure that these sustainable practices are effectively implemented and maintained. This interdisciplinary approach considers both the environmental impacts of industrial processes and the practical challenges industries face in adopting sustainable practices. With a strong commitment to sustainability and innovation, her research advances the development of integrated waste management solutions, contributing to a more sustainable industrial ecosystem.
