Abstract:Effective segregation of solid waste is a basic requirement for efficient waste management and recycling in modern urban settings. Conventional manual segregation techniques are time-consuming, laborious, and prone to errors, as well as unsafe and inefficient. While there are highly advanced automated segregation systems available, they often require expensive infrastructure and sophisticated technology, thereby limiting their use in small-scale and decentralized waste management practices. This paper presents the design and development of a compact automatic waste segregation machine using a rotating plate mechanism that is capable of segregating waste into dry, wet, and metallic fractions. The device uses inductive proximity sensors and moisture sensors along with a microcontroller-based rotary actuation system to enable precise object identification and gravity-fed discharge into separate bins. The experimental results on the developed prototype showed an average segregation efficiency of 94.7%, a processing time of 2.1 seconds per object, and a low power consumption of about 18 W. The suggested arrangement provides a mechanically simple, rugged, and economical solution for decentralized waste management in residential areas, educational institutions, hospitals, and public utility areas, thus promoting environmental sustainability and recycling efficiency.
