Diaper Dissolving Machine

Abstract

In landfills, there are approximately 3.5 million tonnes of disposable diapers, according to the Environmental Protection Agency (EPA). Currently, used diapers are disposed of through burning, burying in the ground, or improper disposal on the ground, including illegal dumping by caregivers. These careless disposal practices pose the risk of spreading infectious diseases and contribute to environmental degradation. To address this significant problem, we propose a suitable nappy waste management system. The system consists of a container mounted on a metal pedestal, a shredder at the bottom, a solenoid valve for water supply, a salt distributor, and a control circuit as its primary components. The '1' key on the keyboard needs to be pressed as soon as a nappy is placed inside the container. The solenoid valve will then use a microcontroller to supply one diaper is worth of water at that moment. Like that, salt water supply is likewise managed. The keyboard's button '2' must be pressed if there are two diapers within the container. It is possible to get rid of five diapers at once because the solenoids' operation time grows in tandem. The shredder motor's working time is also adjusted by the microcontroller in accordance with the solenoid's operating time.
