Refrigerant must be recovered by a certificated technician before the plant is dismantled. Modern refrigerant
recovery machines should be able to remove well over 95% of the refrigerant in an old system.
All recovered HFC refrigerants can either be:
a) Sent for destruction by incineration at a licenced waste facility
b) Sent to a specialist plant that can re-process the old refrigerant into a gas with properties identical to
virgin refrigerant, to create “reclaimed refrigerant”
c) Given a basic cleaning process, to create “recycled refrigerant”
Given the HFC supply shortage that will be created by the phase down process, it is worth trying to send the
old refrigerant for reclamation as it may have a good residual value. If the old refrigerant is too contaminated
it cannot be reclaimed and must be sent for destruction. It is important not to mix different gases in the same
recovery cylinder – as this would render them unsuitable for reclamation.
Reclaimed refrigerant can be used in any refrigeration equipment. Recycled refrigerant must always be
used with care as it may be contaminated or of unknown composition. The use of recycled refrigerant with a
GWP above 2,500 is restricted to either (a) the organisation owning the plant from which the gas was
recovered or (b) the organisation that carried out the recovery.
