The Second International Conference on Sustainable Waste Management: Circular Economy and Resource Recovery builds upon the success of the first conference by addressing the evolving challenges associated with waste generation, resource depletion, environmental pollution, and energy consumption. This edition places a stronger emphasis on transitioning from conventional waste management practices toward circular economy–based solutions that promote resource efficiency and value recovery. By fostering collaboration across academia, industry, and government, the conference seeks to contribute to resilient waste management systems and accelerate the transition toward a circular and resource-efficient economy.
The 2nd International Conference on Sustainable Waste Management invites researchers, academics, industry practitioners, policymakers, and technology developers to submit original research papers, reviews, and case studies addressing recent advances and future directions in sustainable waste management, circular economy, and resource recovery. The conference aims to provide a multidisciplinary platform for knowledge exchange across engineering, environmental science, materials science, energy systems, digital technologies, and policy, with a strong focus on innovation, scalability, and real-world implementation.
