This study addresses the pressing issue of waste management at TUP-Manila by developing an innovative trash bin with a built-in shredder. Designed to efficiently process Styrofoam thermoplastics, glass, tiles, and branches which are abundant in TUP-Manila, the device features a proximity sensor for automatic activation, an ultrasonic sensor to detect bin capacity, and a force-stop button for safety. Powered by a 1-horsepower induction motor and controlled by an Arduino microcontroller, the shredder reduces waste volume significantly, producing fragments of waste between 21 cm – 141 cm. Testing revealed its effectiveness in reducing waste volume, ease of integration into existing waste management systems, and a Very Satisfactory evaluation score of 4.28 across functionality, aesthetics, durability, and safety. While occasional blade jamming and noise levels were limitations, the device demonstrated potential for improving waste handling efficiency and sustainability in academic and industrial settings. Recommendations for future development include incorporating counter-knives for more consistent shredding, enclosing exposed components for added safety, and exploring renewable energy sources. This research highlights the feasibility of integrating mechanical and electronic technologies for sustainable waste management practices.
