How are petri plates discarded?

Petri plates should be discarded in a designated biohazard waste container to prevent contamination and ensure safety. After use, they should be autoclaved or treated with disinfectants to sterilize any microbial cultures before disposal. It's essential to follow institutional protocols for biohazard waste disposal to comply with health and safety regulations. Always handle them carefully to avoid spills or exposure to hazardous materials.
