Development of Smart Waste Bin for Solid Waste Management

2021, International Journal of Sustainable Development and Planning

Abstract

Growing urbanisation in developing countries, population growth, and changes in human activities and consumption patterns have resulted in significant amounts of trash that must be appropriately disposed of, treated, and managed to provide a sustainable environment and a reasonable standard of life for the growing population. The aim of the paper is to design a smart dustbin for proper disposal of waste without any human intervention by providing a smart technology for waste system monitoring, reducing human time, effort, and intervention. This paper presents a smart waste bin integrated with a microcontroller-based Arduino board which is interfaced with ultrasonic sensors, MQ-2 sensor, servo motor, LCD and GSM modem. The Arduino microcontroller is programmed using Arduino C which measures the height of the dust bin using the ultrasonic sensor. Once the waste gets to the pre-set level, the microcontroller activates the GSM modem to send a message to a designated number. The status o...

Key takeaways

  • [26] investigated time management in waste collection in the city by the use of a smart bin in this study.
  • The system is in three modules, the first module which detects a person standing in front of waste bin, by an ultrasonic sensor triggering the servo motor the opening of the waste bin lid for waste to be deposited inside the bin, the lid remains open for 5seconds after the detected objected has been removed.
  • It was displayed on the LCD" The smart waste bin is filled".
  • The MQ2 gas sensor fitted inside the smart waste bin is able to detect alcohol, smoke, methane and carbon dioxide.
  • This paper aimed at developing an optimize waste bin using smart sensing technology and evaluate the performance of the developed smart waste bin.
