Experts in Cuba have undertaken the initialization of a new plant
based on Japanese technology to deal with the destruction of
substances that cause Ozone Layer depletion.
The fragile gaseous strata filters sunlight and impedes harmful solar
ultraviolet radiation reaching the surface of the Earth, thus
preserving human, plant and animal life.
Ozone Technical Office (OTOZ from the Spanish acronym) specialist,
Natacha Figueredo MSc, explained to the Havana Reporter that this
modern installation cosntructed in the Siguaney cement factory in the
province of Sancti Spiritus, commenced operations last April and is
presently in a functional stabilization phase.
During the first stage Ozone depletion substances (SAO from the
Spanish acronym) collected during the substitution of more than
2,500,000 refrigerators and almost 300,000 air conditioners in the
residential sector are to be destroyed.
The works form part of the “Energy Revolution” which fully eliminated
the use in Cuba of chlorofluorocarbons (CFC) in domestic
Hydro-fluorocarbons (HCFC) will later be destroyed in the plant which
will, over the coming months, be collected from refrigeration and
climatization units around the country.
Through this initiative, Cuba has attained the destruction this year
of some 258.4 kilos of SAO, a result which places the island within an
elite group of nations in the region with the capability to undertake
this complex process. Capacity will increase once the plant
The installation is part of a demonstrative collection, recovery,
storage, transport and regeneration of substances detrimental to the
ozone layer initiative, that is the result of a strategy developed by
the OTC and the Montreal Multilateral Protocol Fund, via the United
Nations Development Program (PNUD).
The project seeks to ensure an environmentally safe outcome to SAO
destruction by averting emission into the earth’s atmosphere, thus
contributing to Cuba meeting Montreal Protocol Commitments to
gradually eradicate and reduce SAO use.
Cuba is the first country to totally eliminate CFC consumption in
domestic refrigeration, a significant contribution to the
confrontation of climate change related issues that affect the planet,
because the gasses that impact on the Ozone Layer have a potent
greenhouse effect. According to OTOZ data, the actions undertaken on
the island have reduced CO2 atmospheric emissions by 4 million tons
OTOZ director and doctor in Sciences, Nelson Espinosa explained that
one of the most notable Cuban achievements of the past twenty years is
the total elimination of a group of substances that deplete the Ozone
layer, including the use of CFC’s in the manufacture of pharmaceutical
and industrial aerosols and methyl bromide in the fumigation of crops,
storage units and other industrial installations.
