Biohazard waste refers to materials that pose a risk to human health or the environment due to their infectious, toxic, or otherwise hazardous nature. This type of waste is commonly generated in settings like hospitals, laboratories, and research facilities, where biological agents such as bacteria, viruses, or other pathogens are present. Proper disposal is crucial to prevent contamination and the spread of disease. Examples of biohazard waste include used needles, contaminated gloves, and any materials that have come into contact with infectious substances. Regulations govern the handling and disposal of this waste to ensure safety, often requiring specialized containers and treatment methods to mitigate risks.
