Summary

Per appliance it is estimated that about 150 grams of CFC-12 are contained in the refrigerating cycle and about 600 grams of CFC-11 in the foam. About 80% (at an ambient temperature of 20°C) of CFC-12 is dissolved in refrigerating machine oil. It is necessary to pulverize insulation and recover CFC-11 from the fine foams in this insulation. CFC-11 that is degassed in the shredder must be recovered with an absorption unit to achieve a high recovery rate. CFCs, which bond together firmly and are stable, require a temperature of at least 800°C for destruction. Since a few years ago, destruction of CFCs has received practical application with a few exceptions.
