Medical waste also known as clinical waste usually refers to waste products that cannot be considered general waste, produced from healthcare premises, such as hospitals, clinics, doctor’s offices, labs and nursing homes. Discarding of this waste is an environmental concern, as many medical wastes are known to be infectious or biohazardous and could potentially lead to the spread of contagious diseases. Examples of infectious waste include blood, contaminated "sharps" such as needles and scalpels, and particular body parts. Sharps include used needles, lancets, and other tools capable of penetrating skin. Infectious waste is often sterilized by being “cooked” at extremely high temperatures. The most common method of sterilization is an autoclave. The autoclave uses steam and pressure to sterilize the waste. Although the autoclave is known to be as one of the most effective ways because it reduces the amount or size of waste we put out, it is also problematic because an autoclave comes at a very high price as well as a new issue that deals with how the ash is disposed. One particular problem that has always been emphasized are the used of needles and syringes, because of their high likelihood of stick value or of breaking the skin. Chemicals that are not properly disposed also place a huge environmental concern. If an animal came in contact with a chemical or improperly disposed gauze, the animal may contract something that could be detrimental to the survival of an entire food chain. According to health care without harm article, "Hospitals generate more than two million tons of waste each year." But other United States EPA
