The total collection and correct disposal of ozone-depletion and greenhouse refrigerant fluids are nowadays professional standards, given that the activity of a certified refrigerator engineer or a refrigeration/conditioning system owner can't be outside of a correct and responsible control of the life-cycle of said fluids, which are de facto hazardous waste. The total collection and correct disposal are also law obligations as provided by European and local regulations in force. Not complying results in administrative and criminal penalties. General Gas, thanks to its Program Agreement with the Environment Ministry, has already implemented the GreenWatch service which provides nationwide collection of exhaust refrigerant fluids destined to disposal (mixed and/or heavily polluted CFC, HCFC, HFC) and/or regenaration (non-mixed or with oil and residue levels below specific values HFC). Refrigerants collected from refrigeration or conditioning systems is de facto a hazardous waste to environment (CER code 140601) and as such must be disposed solely at a center authorized by the Environment Ministry through a Program Agreement.
