Description
High purity, technical antifreeze fluid, which is also used in building services, heat recovery systems and as a refrigerant in motor vehicles.
In an industrial environment, the use of ethylene glycol is more common due to lower purchase prices and lower operating costs due to lower viscosity (lower pump consumption). and better heat transfer properties.
Ethylene glycol is a toxic substance that is hazardous under REACH and requires greater care in terms of safety at work.

Life Cycle Assessment (LCA) - Per 1 tonne (T) :
-
Based on Ecoinvent database (from raw material extraction to the end of the production process)
-
Carbon footprint = ∿ 1630 kg CO2 eq / T , which is approximately equal to (US EPA data):
-
∿ 6590 km travel (car)
-
∿ consuming 690 liters of petrol
-
∿ burning 820 kg of black coal
-
∿ 2.5 month-long energy consumption of an average European household
-
∿ burning 4 barrels of oil
-
Carbon neutralization of this quantity would require at least:
-
∿ Development of 27 seedlings over 10 years
-
∿ One-year-long carbon sequestration capacity of 0.8 hectare forest
