ABSTRACT

The unsystematic waste management is a growing environmental concern in today’s rapidly developing world, contributing to flooding, soil and water degradation, and posing risks to public health. This study presents the development of an automated segregator trash bin for solid waste, which also features an electronic charging incentive for users. The research aimed to design and implement the hardware and electrical circuit, develop a software algorithm, ensure effective waste segregation, assess detection accuracy, and verify the prototype's charging functionality. The prototype’s construction involved assembling hardware components and electrical circuits, which include a microcontroller, capacitive, inductive, and ultrasonic proximity sensors, actuators, charging bays, lead-acid batteries, and waste bins. The researchers employed an experimental design and used statistical tools such as mean, standard deviation, and paired t-tests to evaluate the prototype's performance. Results indicated that the prototype achieved 100% accuracy in segregating dry plastic trash accurately, while metal had 76% accuracy. A significant value of p = 0.002091, which is less than 0.05, the significance level, in the battery’s voltage output between the initial and final tests confirmed the battery’s reliability as a power source. Additionally, the charging bays provided users with an incentive by offering at least 20 minutes of charging time for their devices in exchange for correct waste disposal. Overall, the prototype completed all stages of its operation: detection, segregation, and charging. This system encourages proper waste segregation and rewards users for participating, benefiting individuals and the environment. This innovative approach to waste management promotes sustainable practices and offers a practical solution to one of today’s major environmental challenges.
