on sustainable e-waste management in Ghana
Step 1 is followed by a manual extraction of the compressor <strong>and</strong> possibly the cooling grid at
the backside of the device. The corpuses are passed on to step 2 of the CFC-recovery
process.

Step 2 of CFC-recovery
In step 2 of the refrigerator recycling process, the CFCs in the isolation-foam (PUR-foam) of
the devices are recovered. Generally, there are two major ways to carry out step 2:
The first option is based on manual extraction of the foams, using scraping <strong>and</strong> cutting tools
to separate the PUR-material from the casing material. The foam is then passed on to a
treatment facility that is able to incinerate the foam at temperature regimes that destroy the
