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.
