IS THERE A MORE SUSTAINABLE CLEANING METHOD THAN THIS? 10 Key benefits of Dry Ice Blasting – #4 January 13, 2020




Dry ice blasting = sustainability. 

I don’t think I have ever seen a cleaning method this good for the environment.  Period.  Here’s why.

Dry ice blasting recycles and reuses carbon-dioxide before it is released back into the environment.

By harvesting carbon dioxide, a natural gas that is a by-product of many industrial processes, and processing it into a frozen blast media, (called Dry Ice,) dry ice blasting is taking what is effectively the worlds #1 waste product and giving it a second useful life (chemical free cleaning) before releasing it back into the atmosphere, where it was destined for originally anyway.

How good is that – a waste product getting a second life as an environmentally friendly cleaning agent!


How is recycled carbon-dioxide used for cleaning?

Dry ice blasting is a blasting process similar to sand-blasting or soda-blasting.

However, the ‘media’ that Dry Ice Blasting uses to remove the soil from a surface is rice sized pellets of frozen CO2 (-78 degrees Celsius.)  These pellets are propelled towards the soil by compressed air, and on impact with the soil the Dry Ice pellets give the soil a thermal shock, causing it to go brittle and loose it’s adhesion.  Then the frozen CO2 gas instantaneously turns from a solid into a gas (a process called sublimation) which is like a mini-explosion as the gas rapidly expands.  This action, coupled with the kinetic energy of the Dry Ice pellets hitting the surface at the speed of sound, causes the soil to be dislodged and fall away to the ground.

Using frozen CO2 as Dry Ice Blasting media is a “net zero” carbon foot print cleaning methodology.  It’s one of the most exciting sustainability secrets I’ve seen this decade.  Tell your friends and colleagues!
