Large appliances (white goods) require special disposal methods because some of them contain chlorofluorocarbons (CFCs), which are also known as Freon.
Freon represents several different CFCs, which are a group of aliphatic organic compounds containing the elements carbon and fluorine, and, in many cases, other halogens (especially chlorine) and hydrogen. Freons are colorless, odorless, nonflammable, noncorrosive gases or liquids. During the 1990s, the US Congress passed a law banning the use of CFCs in new products and more environmentally friendly hydrofluorocarbons were developed for use as refrigerants.
Federal law mandates that refrigerants be recovered and recycled. Appliances that contain refrigerants include refrigerators, freezers, air conditioners, water coolers and dehumidifiers. Regardless of where you or your waste hauler takes your appliance, the law stipulates that the refrigerants must be recovered before the unit is disposed because CFCs released into the atmosphere can deplete the ozone.
