Products includes fridges, freezers and any appliances with refrigerating devices such as water coolers. Some appliances also contain refrigerant gases classified as Ozone Depleting Substances (ODS) such as chlorofluorocarbons (CFC), hydro-fluorocarbons (HFC) and hydro-chlorofluorocarbons (HCFC) that are now banned.
These gases are captured and treated in ODS recovery plants. Cold appliance de-pollution entails a variety of processes: compressors are decontaminated to recover ODS and oils; insulating foam is treated to recover ODS; metals are salvaged and resold; and plastics can be re-used for new products. Recovered oils and ODS are destroyed in a specialised treatment process.
