Infectious Waste, Bacteria, UV-C


Currently, Coronavirus is unstoppable causing people to alter their lifestyle and adapt to a new normal. An example is the retention of infectious waste such as masks, tissues, drinking straws, antigen test kits (ATK), etc. since these tend to have secretions. Data from the Department of Health from 2-3 years ago shows that more than ten million infectious wastes have been destroyed as it occurs of bacteria gram positive and bacteria gram negative. However, ultraviolet type C (UV-C) can destroy these bacteria. In this research a UVC system has been designed in the trash bin and initiates once the infectious waste has been inserted and the cover is closed. Lighting of the UVC system was performed at intervals of 10, 15, and 20 minutes with a timer relay. The results show that utilizing the UVC system for the longer time of 20 minutes reduced bacteria more than 90 percent which increases the safety of the hazardous waste before it can be disposed of.
