Which of the following are main categories of health care waste?

The correct answer encompasses the primary categories of health care waste, which are essential for proper management and disposal within healthcare facilities. These categories reflect the different risks and handling procedures required for various types of waste generated in medical settings.

General waste refers to non-hazardous materials that do not pose significant risk to health or the environment. Hazardous waste includes any material that can be harmful to human health or the environment, typically requiring special handling and disposal protocols. Infectious waste is particularly important in healthcare management, as it consists of materials that can transmit infections, such as used needles, contaminated supplies, and laboratory cultures. Lastly, radioactive waste is generated from the use of radioactive substances in diagnostics or treatment, requiring stringent handling to protect health workers and the public.

Notably, the other options presented do not accurately reflect the primary classifications needed for effective health care waste management. They either mix unrelated categories, such as garden and construction waste, or include types of waste that are not typically associated with health care settings, like electronic and food waste, which are better categorized in other waste management systems.
