Design and Development of a Mechanized Waste Cleaning System Using Sprocket-Chain Mechanism

Abstract

This research presents the development of a mechanized waste cleaning system utilizing a sprocket-chain mechanism integrated with rakes and powered by a DC motor. The primary objective is to reduce manual labor and enhance the efficiency of waste collection in public and industrial environments. The system comprises sprockets, chains, rakes, a structural frame, and stroller wheels for mobility. The rakes, attached to the chain, lift waste as the chain rotates via sprockets driven either manually or by a motor. The prototype was fabricated using locally available components and tested under controlled conditions. Key parameters, such as rake pitch, chain tension, and motor torque, were optimised to ensure smooth operation. The system demonstrated effective waste lifting and transport, with minimal energy consumption and maintenance requirements. The environmental impact assessment indicates a reduction in manual waste handling and associated health risks. Furthermore, the system aligns with multiple UN Sustainable Development Goals (SDGs), including SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Cities and Communities), and SDG 13 (Climate Action). The results validate the system’s potential for scalable deployment in urban sanitation, river cleaning, and industrial waste management. The study concludes that the proposed mechanism offers a sustainable, low-cost, and efficient solution for semi-automated waste collection.
