On receiving recovered refrigerants at the
RRR Hub, cylinder details are recorded,
content tested, and mass of refrigerant
weighed. On receiving at the Hub, the
recovered refrigerant is checked to
assess whether it can be reclaimed. Any
contaminated refrigerant, which cannot
be reclaimed, is sent for destruction to
the nearest facility in Europe and the
client billed for the destruction costs.
Generally, refrigerant recovered from
well-maintained plants and recovery
done according to standard practice can
virtually be all reclaimed. The percentage
which cannot be reclaimed and sent for
destruction is less than 2%.
On site recovery of refrigerants is done
by Enviroserve teams, at no charge to
large clients who have entered into a
contract or others do their own recovery
with cylinders provided by Enviroserve. A
continuous supply of recovered refrigerant
is vital for the sustainability of TRH by
Enviroserve as a viable and profitable
enterprise.
Hosting of seminars on ozone
depletion, training of technicians in
recovery, engagement with government
departments, participation in all climate
change meetings, regular emails to clients
to assess their requirements, are part of the
ongoing Enviroserve marketing strategy to
promote RRR.
Many corporations now also see RRR as
part of their corporate social responsibility
(CSR) and insist that all their service
providers do the same and has created
further awareness for all role players to
follow the Enviroserve lead towards saving
our planet.
Enviroserve has the capacity to reclaim
8 000kg/day. At times, batches are
consolidated to have the plant operate at
full capacity. All recovered refrigerants are
reclaimed to the ARI 700 standard and is
comparable to virgin refrigerant.
With the Enviroserve equipment,
refrigerant can be recovered on site at the
rate of 100kg per minute. Stuart Fleming
from Euroserve, emphasised that recovery
was not just about collecting a saleable
commodity but was much quicker than
the time spent in waiting for systems to be
fully vented when allowed to blow off.
Recovered refrigerant which can be
reclaimed is exchanged at Enviroserve for
quality assured reclaimed refrigerant at
a fraction of the price of virgin imported
refrigerant. The supply of reclaimed
refrigerant is not only to clients in the
Middle East, but as far afield as Canada.
At the time of the visit a consignment
of yellow painted 50kg cylinders of R22
was about to be dispatched to Canada
ahead of the 31st December 2019 ban on
the imports of reclaimed R22.
The RRR at Enviroserve is also
promoted as a step towards reducing
the environmental impact of disposable
cylinders.
