Hospitals dispose of amputated limbs as medical waste under the 1988 Medical Waste Tracking Act, notes the Environmental Protection Agency (EPA). Medical waste includes all sorts of waste generated from treatment of humans or animals, including removed body organs, such as limbs, tonsils or appendices.
Biomedical waste must be disposed of properly under the law. Hospitals may have some sort of onsite facility to treat or dispose of waste. Often, this involves incineration. The treatment of medical waste is controlled by each state, and regulations for disposal vary from state to state, notes the Healthcare Environmental Resource Center. Some facilities may have a company that picks up and disposes of their medical waste products.
