Environmental sustainability of dry ice blasting

No hazardous substances:
Dry ice blasting involves no noxious or environmentally harmful chemicals or solvents.
Therefore no poisonous or harmful vapours are produced.
This means that personnel are not put into danger by the use of hazardous and harmful substances.

Simple disposal:
Dry ice blasting leaves no abrasive residues.
The loosened dirt falls to the ground and can be swept up.
Only the dirt and nothing else needs to be disposed of.
If, on the other hand, chemicals and solvents are used, noxious residues that must be laboriously disposed of remain.

No secondary waste:
With sand, soda and water blasting the medium used becomes problematic waste whenever hazardous stains are removed.
A very large amount ofsecondary waste accumulates, which, depending on conditions, can be very difficult and costly to dispose off.

Carbon dioxide production:
CO2 is a by-product from other industrial processes.
For example carbon dioxide arises from CO2 cleaning in the synthesis ammonia and methanol.
A large portion of the CO2 used is extracted from the raw carbon dioxide gas that arises in the chemical processing of crude oil and natural gas as exhaust. Furthermore carbon dioxide results from combustion processes in power plants and fermentation.
Therefore in industrial countries CO2 is no longer produced for its own sake and the burning of fossil fuels for extracting CO2 is a thing of the past.
