The CO² given off during the production processes is captured, purified and stored without losses until needed. When the CO² is returned to the atmosphere during the blasting process, no new CO² is produced. So you are, in effect, putting back into the atmosphere the CO² that was taken out during the original production process.
With a low temperature of -78°C, solid dry ice has an inherent thermal energy ready to be tapped. At atmospheric pressure, solid CO² sublimates directly to vapour without a liquid phase.
What this means is that the dry ice blast medium simply disappears, leaving only the original contaminant to be disposed of. And because there is no water involved, dry ice blasting is the safer, practical alternative for cleaning in the vicinity of electrical sources.
Environmental facts about dry ice blasting
- Dry ice blasting is safe to use with food processing equipment
- Dry ice blasting does not release harmful gases into the atmosphere
- Dry ice blasting does not generate secondary waste
- Dry ice blasting is safe and non-toxic
- Dry ice blasting reduces or eliminates employee exposure to (and corporate liability from) the use of dangerous chemical cleaning agents
Other cleaning methods can be toxic
- Sand, soda, or water blasting can leave toxic secondary waste to be cleaned up in addition to the toxic substrate
- Sand, soda, or water blasting can create downstream contamination that effects surrounding installations
- Soda blasting can kill surrounding vegetation
- Chemical and solvent cleaning methods are toxic, which creates toxic waste to be disposed of
- Workers are exposed to potentially harmful substances through the use of chemicals and solvents
Why risk potential harm to the environment, equipment and users, when dry ice blasting is the safe, environmentally friendly alternative!
