Protection of the ozone layer

Refrigerator demanufacturing according to the the SEG system protects the recovering ozone layer. Even though CFCs are no longer being used. The CFC in old refrigerators still retains all of its potential hazard. Every gram that escapes unhindered weakens the ozone layer.

CFCs rise to the stratosphere and there they damage the ozone layer that protects the earth from hard UV radiation. The consequence of this damage is an increase in short-wave UV radiation that represents a danger to people, animals and plants.

Climate protection

The SEG’s activities contribute greatly to climate protection. One of the major approaches to climate protection is the reduction of emissions of greenhouse gases caused by man.

Water vapour, CO2 and methane are natural greenhouse gases. Global warming is primarily caused by an increase in the proportion of natural greenhouse gases, mainly through the combustion of fossil fuels, which releases CO2.

However, products such as CFCs and the substitute coolants now used also contribute to the greenhouse effect. The impact of CFCs on the greenhouse effect is about 10,000 times greater than that of carbon dioxide. This becomes clear when one knows that, despite their comparatively low proportion in the atmosphere, CFCs contribute 22% to the creation of the greenhouse effect.

The substitute substances in refrigeration, freezing and air conditioning technology have greatly reduced potential for ozone destruction. Second-generation substitute substances such as the widely-used R134a no longer have any potential for ozone destruction. However, their contribution to potential greenhouse effects is high. With R134a this is 1,430 times greater than with CO2 and with others it is up to 12,000 times greater. Today hydrocarbon gases (pentane/butane) are to be found in domestic refrigerators as coolants as well as in insulation foam and these appliances are designated as VHC appliances. (VHC stands for volatile hydrocarbons ). The potential greenhouse effect of pentane/butane is about three times greater than that of CO2.
