    Design & Implementation of Smart Waste Collection System with Optimized Route Planning
    (SLIIT City UNI, 2025-07-08) Josheph, A L; Rajaguru, N M
    With the growth of the global population, the challenge of waste management has become more complex. Effective waste management is no longer just a necessity but a critical concern for public health, urban sanitation, and ecological sustainability. Identifying the filled public waste bins in cities and collecting them effectively is one of the essential initial tasks of waste management, to address it more effectively and cost-efficiently the "Smart waste collection system with optimized route planning" is designed. The prototype system utilizes microcontrollers, a Photo- Voltaic power supply unit, ultrasonic sensors, and a wireless module to detect and communicate bin status in a multi-hop wireless network cluster. Each bin is equipped with an Ultrasonic sensor to measure the garbage level and the data is transmitted through neighboring bins to a central control unit using the ISM-based wireless communication multi-hop network, enabling remote monitoring. When bins are detected as filled, their locations are processed to determine the shortest and most efficient route for the collection of garbage using the Google Maps Directions API. The system was tested successfully using a prototype with three waste bins equipped with sensing units, and setting the location on the maps through a cloud-based web visualization built using basic HTML, Python, and Javascript, the system performed accurate fill-level detection and real-time route planning for garbage collection. This solution offers a cost-effective and scalable approach to smart urban waste management by reducing manual monitoring and optimizing collection routes with traffic awareness.

    OPTIMUM ROUTE PLAN FOR EFFECTIVE COLLECTION OF AN INDUSTRY LEVEL BY PRODUCT/WASTE
    (Sri Lanka Institute of Information Technology, 2023-03-25) Peiris, M; Gamlath, I; Bandara, S
    Effective waste management is critical for sustainable development in manufacturing industries, especially in managing industrial waste. Industrial waste can be transformed into high-quality products through circular economic practices, promoting sustainable development. This research aims to develop a methodology to identify an optimal route plan for collecting and distributing industrial waste and products, promoting circular economy practices. To achieve this objective, waste generated by a selected industry needs to be investigated to determine its potential for reuse in other industries. Data on the quantity and variety of waste generated daily was collected, and industries that use waste as a resource to develop their products were identified. The linkage between industries that demand waste as a raw material and those that generate waste can be established using a Geographical Information System. The study focuses on concrete demolition waste and aims to link metal crushing, aggregate suppliers, and concrete block manufacturing industries. The optimized route plan would benefit third-party subdistributors, reducing transportation costs and facilitating effective transportation. Additionally, it would enable new entrepreneurs to establish industries and maintain a good supply chain, creating jobs.
