Name a safe method for disposing of laboratory waste.

Using autoclaving or incineration to dispose of laboratory waste is a safe and effective method for managing this type of waste. Autoclaving involves using high-pressure steam to sterilize materials, which is particularly suitable for biohazardous waste, ensuring that pathogens are rendered non-infectious and safe for disposal. Incineration, on the other hand, is effective for certain types of hazardous materials that cannot be sterilized through other means, destroying harmful waste through high-temperature combustion.

This method of disposal is critical in healthcare and laboratory environments, where materials may pose health risks if not treated properly. It ensures that hazardous pathogens or chemicals are safely eliminated, minimizing the risk of environmental contamination and exposure to personnel.

Other methods mentioned, such as landfilling or burning in open air, do not guarantee complete destruction of pathogens or chemicals and can pose serious risks to human health and the environment. Additionally, dumping in a water body can lead to severe ecological damage and public health issues. Thus, autoclaving and incineration represent controlled, regulated, and environmentally responsible options for laboratory waste disposal.
