A wide variety of wastes are too hazardous to be disposed of by traditional means. Hospitals, clinics, laboratories, nursing homes, funeral homes, dental offices and veterinary clinics are just some examples of places that produce potentially dangerous bioactive waste, often referred to as biomedical waste. Proper disposal of biomedical waste is a complex process that must be carefully controlled to avoid serious public health risks. The waste must be placed in special bags, stored separately, transported in refrigerated trucks and carefully disposed of to eliminate potential exposure. In many cases, the waste must be autoclaved before it is land filled. This complex process results in exceedingly high costs for the disposal and treatment of biomedical waste.

The anesthetic gases and vapors which leak into the indoor atmosphere during medical procedures are considered waste anesthetic gases (WAGs). The exposure is of relevance to thousands of professionals in hospitals, operating theaters, patient recovery rooms, dental offices, and veterinary clinics around the world, who may be continually exposed to the waste anesthetic gases during their workday. Typical gases of concern include nitrous oxide N2O and several halogenated compounds in vapor form, such as sevoflurane, isoflurane, enflurane, halothane, desflurane, and methoxyflurane. Short-term exposure to these gases may lead to several symptoms, such as dizziness, headaches, fatigue, nausea. Long-term exposure to some of the anesthetic agents may result in sterility, birth defects, cancer, and liver and kidney disease.
