As global populations grow and urbanization accelerates, sustainable waste management has become a critical challenge for policymakers, communities, and businesses. This study deals with the current awareness, attitudes, practices, and barriers related to sustainable waste management across diverse demographic groups. Using a structured, multi-dimensional survey instrument, data were collected from a cross-sectional sample comprising 68 students, professionals, municipal staff, and business owners. The paper evaluates the effectiveness of recycling and composting facilities, the adoption of modern waste management technologies, and public willingness to pay for better services. It further explores stakeholder preferences for compensation models, financial incentives, and policy measures that can drive community engagement and corporate investment in circular economy initiatives. Findings indicate a strong public recognition of the importance of sustainable waste practices, yet reveal systemic gaps in infrastructure, funding, and government enforcement. The study identifies AI-based waste sorting, digital tracking systems, and community-driven education as key enablers of future sustainability. The results inform practical strategies and policy recommendations to enhance waste management efficiency, promote behavioral change, and support national goals of achieving zero waste and climate resilience. This research contributes to the global discourse on sustainable urban development and offers scalable models for emerging economies.
