Which of the following is NOT considered hazardous waste?

Non-contaminated paper towels are considered safe for disposal and are not classified as hazardous waste. Hazardous waste is defined as waste that poses a level of risk to human health or the environment, often because it contains toxic, reactive, ignitable, or corrosive materials.

Used gloves, contaminated glassware, and chemical spills all fall into categories that may pose such risks, as they can be contaminated with potentially dangerous substances or chemicals that could harm individuals or the environment if not disposed of properly. Non-contaminated paper towels, on the other hand, do not carry these hazards and can typically be treated as regular waste. This distinction is essential for proper waste management practices in the biomedical field, ensuring that hazardous materials are handled according to safety regulations while non-hazardous items are disposed of more easily.
