The rapid escalation of global waste production and the simultaneous depletion of finite natural resources have necessitated a fundamental economic shift from a linear "take-make-dispose" model to a Circular Economy. However, a significant barrier to the widespread adoption of circular practices is the fragmentation of the market, which prevents consumers and businesses from efficiently trading reusable, upcycled, and recyclable goods. Current digital solutions are often generalized, lacking the specific intelligent tools required to foster trust, efficiency, and discovery in second-hand trading. This paper presents the design and implementation of the "AI Smart Circular Economy Marketplace" (EcoMarket), a centralized, intelligent web-based ecosystem tailored for sustainable commerce. The proposed system utilizes a modern, scalable technology stack, comprising Next.js for a high-performance frontend and Node.js for a robust backend architecture. Furthermore, the system integrates distinct intelligent algorithmic modules to automate product categorization, provide personalized user recommendations based on behavioral analysis, and estimate product lifecycles to promote informed purchasing. By simplifying the user experience and providing data-driven insights into product reusability, this platform aims to bridge the gap between supply and demand in the circular economy, ultimately contributing to significant waste reduction and improved resource efficiency.
