Biomedical waste is any waste produced during diagnosis, treatment, or research involving humans or animals. There are four main types of biomedical waste: infectious, hazardous, radioactive, and general. Segregation of biomedical waste involves separating different categories of waste at the source to reduce risks and costs of handling and disposal. Common methods for disposing of biomedical waste include incineration, chemical disinfection, autoclaving, microwave irradiation, land disposal, and inertization.
