Abstract - The rapid growth of urban populations and unsustainable waste management practices are leading to severe environmental, economic, and public health challenges. Traditional waste collection systems, which often rely on fixed schedules, are inefficient, resulting in unnecessary fuel consumption, increased operational costs, and overflowed bins. This paper proposes a novel smart waste management system that integrates Internet of Things (IoT) and Artificial Intelligence (AI) to optimize the entire process. The system utilizes ultrasonic sensors installed in smart bins to monitor waste levels in real-time. This data is transmitted via a LoRaWAN network to a centralized cloud platform. An AI-powered predictive analytics module then processes this data, along with historical and contextual information (e.g., location, day of the week), to forecast waste accumulation patterns and generate dynamic, optimal collection routes and schedules for sanitation vehicles. The proposed system was implemented and evaluated through a simulation model and a small-scale prototype. Results indicate a potential reduction in collection frequency by up to 40% and a decrease in total distance traveled by collection vehicles by over 30%, significantly cutting operational costs and carbon emissions. Furthermore, the real-time monitoring capability prevents bin overflow, thereby improving urban cleanliness. The study concludes that the integration of IoT and AI presents a robust, scalable, and sustainable solution for modernurbanwaste management,transforming itfrom a static, reactive service into a dynamic, efficient, and intelligentone.

1.INTRODUCTION
Inrecentyears,rapidurbanizationandpopulationgrowth have led to a significant increase in waste generation, creating major challenges for municipalities and the environment. Traditional waste management methods often rely on manual monitoring and fixed collection schedules, which result in inefficiency, increased operationalcosts,andenvironmentalpollution.Toaddress these issues, the integration of *Internet of Things (IoT)*
and *Artificial Intelligence (AI)* offers a modern and efficient solution for developing a *Smart Waste ManagementSystem*.
IoT enables real-time monitoring of waste levels through smartsensorsinstalledinbins,whichcollectandtransmit data on waste volume, temperature, and bin status to a centralized system. AI technologies, on the other hand, analyze this data to optimize collection routes, predict waste generation patterns, and support decision-making processes. The combination of IoT and AI not only improves resource utilization and reduces operational costs but also promotes sustainability and cleaner urban environments. This intelligent system contributes significantly to the development of *smart cities*, where technology is leveraged to enhance public services and environmentalmanagement.
