Abstract from DBPedia
    Chemical waste is a waste that is made from harmful chemicals (mostly produced by large factories). Chemical waste may fall under regulations such as COSHH in the United Kingdom, or the Clean Water Act and Resource Conservation and Recovery Act in the United States. In the U.S., the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), as well as state and local regulations also regulate chemical use and disposal. Chemical waste may or may not be classed as hazardous waste. Chemical waste that contains radioactive elements poses particularly difficult problems of disposal. The difficulties are partly technical and partly political: the radioactive constituents that find their way into groundwater and surface water must be kept to exceedingly small amounts for very long times, and fear of the mysterious effects of radiation makes politicians reluctant to consider disposal of radioactive waste in the area of their constituents. A chemical hazardous waste is a solid, liquid, or gaseous material that displays either a “Hazardous Characteristic” or is specifically “listed” by name as a hazardous waste. There are four characteristics chemical wastes may have to be considered as hazardous. These are Ignitability, Corrosivity, Reactivity, and Toxicity. This type of hazardous waste must be categorized as to its identity, constituents, and hazards so that it may be safely handled and managed. Chemical waste is a broad term and encompasses many types of materials. Consult the Material Safety Data Sheet (MSDS), Product Data Sheet or Label for a list of constituents. These sources should state whether this chemical waste is a waste that needs special disposal.
