Design and Development of Smart Waste Bin for Effective Waste Collection and Management

Abstract

AbstractIn modern cities, waste management has become a problem as waste is being generated faster than it is being managed, and this is leading to serious environmental pollution. Most conventional trash bins in place are not being emptied efficiently enough which leads to the overflow of waste and the breed of pests, insects and the dreadful diseases they cause and spread. It is a known fact that carbon dioxide and other air pollutant resulting from unmanaged wastes causes global warming which is dangerous to human wellbeing. So, this work proposes a smart waste bin to curtail indiscriminate disposal of waste and it incorporate the use of mobile technology to notify the waste management personnel for timely and effective handling of the waste. The designed intelligent waste bin is made up of two systems. The automated lid system is the first part, and it is responsible for the opening and closing the cover-lid of the bin without the need for physical contact between the user and the bin. It also prevents the user from coming in contact with the waste-borne germs, bacteria, and viruses that may be present on the surface of the waste bin. The second is the communication system which will be responsible for informing the waste management authorities about the level of the waste in the bin so that the bin can be emptied as soon as possible. The smart bin opens when the incoming trash is at a distance of 20 cm (or less) to the bin. The bin will not open at a distance greater than this threshold of 20 cm, likewise it will not open when the waste bin is 95% full relative to its capacity. The waste management personnel are notified through the communication system attached to the smart bin when the bin is 95% full so that the waste in the bin could be emptied. This prevents trash overflow from the bin and ultimately makes the environment cleaner, more eco-friendly and prevent global warming.KeywordsSmart binArduino NanoUltrasonic sensorServo motorGSM module
