Recently developed substitute materials in cooling technology, refrigeration technology and climate technology have a much lower potential for damaging the ozone layer. For the second generation of substitute materials, such as the propellant and coolant R-134a, this potential is reduced to zero. However, these substances have an extremely high global warming potential.
Today, household refrigerators contain hydrocarbon gases such as pentane or butane as coolants and in the insulating foam.
1 refrigerator per year
2.8 t CO2 eq.
(Containing CFCs / hydrocarbons)
1 car per year
6.9 t CO2 eq.
1 house per year
3.7 t CO2 eq.
This comparison makes it clear why every gram of CFCs / hydrocarbons must be extracted and destroyed. Demanufacturing, such as that done by SEG, is an important stepping stone in the pursuit of CO2 reduction.
