EPA orders recycling of coolant chemicals
April 24, 1993, Chicago Tribune
The government laid down the law Friday on refrigerators and air conditioners: The chemicals that cool them must be recycled to help preserve the Earth’s ozone layer. The Environmental Protection Agency decreed that repair workers who service air conditioners and refrigerators, both residential and commercial, must use new equipment to prevent escape of chlorofluorocarbons (CFCs) and other ozone-depleting chemicals. In addition, the EPA regulation requires that when owners dispose of refrigerators and air conditioners, the refrigerants must be safely removed and recycled. The regulation implements a section of the Clean Air Act amendments of 1990 that barred CFC emissions.
