Abstract

The research aims to create a prototype infectious waste bin for public toilets in commercial buildings to automatically disinfect contaminated toilet paper to prevent the spread of diseases. This study explores commercial buildings to analyze toilet waste management and to design a bin prototype with 3 sections. (1) The first level is a touchless lid for receiving toilet paper waste. (2) The second level is to be sprayed thoroughly over its entire surface with disinfectant (0.1% or 1000 ppm sodium hypochlorite) via 2 positions of fog nozzles made of brass with a flow rate of 7 liters per hour spread disinfectant evenly cover all of the waste within 45 seconds and retrained for 15 minutes to eliminate germs. (3) The waste then passes to the third or bottom level, which operates as a drawer that staff opens to retrieve the waste. The study gathers feedback from facility managers to evaluate the innovative product and establish its credibility. The first factor to be considered is its effectiveness in disinfection. User feedback on functionality, aesthetics, usefulness, and purchase decision is positive. The results of the prototype bin disinfection test showed that it could completely eliminate E. coli. and 99.995% to eliminate B. subtilis.
