It sublimates and returns to the atmosphere as carbon dioxide (CO2) gas. CO2 is a naturally occurring element that constitutes less than 1% of our atmosphere.

People sometimes think it disappears too, but it does not. All cleaning involves the relocation of dirt. When you mop a floor, the dirt moves from the floor, to the mop, to the water in the bucket. With dry ice, the dirt moves from an undesirable area to an area where you can better deal with it. If it is a dry substance, it generally falls to the floor where it is swept away or vacuumed during normal maintenance. If it is a wet substance like grease, you take a methodical approach like hosing down a driveway. You start at one end and guide the grease to the other end where it is vacuumed or squeegeed up.

Yes, however, the removal rate is dependent on many factors including: the underlying surface profile of the substrate; the thickness of the coating; the adhesive bond strength of the coating; and the cohesive strength of the coating (generally a function of age). Paint removal rates can vary dramatically, from 300 square feet/hour down to 1 square foot/hour. Generally, if you have concerns with contamination, toxic substances, waste disposal, or substrate damage, dry ice blasting should be considered as a cleaning option. Otherwise, grit blasting is probably a more efficient method for paint removal.

Yes, with proper ventilation. Because CO2, or dry ice, is 40% heavier than air, placement of exhaust vents at or near ground level is recommended when blasting in an enclosed area. In an open shop environment, existing ventilation is sufficient to prevent undue CO2 buildup.

Dry ice pellets vary in uniformity of size and hardness. Triventek can deliver consistent, uniform pellets. This is due to having the pellet machine in house ready to use when you need them. Often the logistics of getting pellets can be a daunting task, and when you finally receive them, they lack the consistency of fresh pellets.
