Environmental Protection by Recycling - Dry Ice Blasting.....

Hi everyone. I am an engineering student. I read something called dry ice blastingand hazardous waste disposal while browsing net. Well I don’t know why, but I am curious to know about it. I know about traditional labor intensive methods like scrapers, wire brushes, sand blasting and pressure washing. I know dry ice is basically solid form of CO2, but I have no clue about this dry ice blasting and industrial cleaning .
Can somebody throw some light on this or at least suggest some site where I can find some info on this.

There are service companies available that offer dry ice blasting for cleaning equipment. The method uses dry ice pellets and compressed air. For a demonstration, go to http://www.diamonddryiceblasting.com/
