If your trying to decide on an Environmentally Friendly Surface Restoration process, choose Dry Ice Blasting.
In addition to being clean and safe, it is also important to remember that dry ice is obtained as a by-product of other industrial processes – i.e. it is made from reclaimed CO2. It does not produce CO2 or add CO2 to the atmosphere and therefore does not contribute to the greenhouse effect.
Co2 is produced from many forms of the manufacturing industries. These companies will capture this Co2 rather than release it into the atmosphere.
The Co2 is purchased by companies while still in a gas form, and then turned into liquid Co2. It is the liquid Co2 that is used in hundreds of industries and applications, including Dry Ice Blasting.
‘But we are still putting Co2 into the atmosphere’ is the next question I nearly always hear. Technically yes. But the Co2 we use was already there. It existed before we recycled it and now we have put it to a secondary use.
And by putting it to a secondary use, we will have replaced a technique or method which would have a carbon footprint.
Dry Ice Blasting replaces chemicals, rags, brushes, power tools, grinding discs etc. to perform the same job. The CO2 footprint to manufacture these items outweighs the Dry Ice Blasting process, and the rags that would have been used to capture the chemical and grease would have been disposed of and replaced daily using a landfill or an incinerator.
Dry ice blasting will do the same job, better and faster, with no chemical and no waste stream and therefore having made no new Co2 in the process.
