IS DRY ICE AND CO2 HARMFUL?
The dry ice is made from waste CO2 from manufacturing facilities, such as refineries, fertilizer plants, and ethanol plants. This CO2 would have been vented to the atmosphere; instead it is made into dry ice, which is used to perform cleaning procedures that would otherwise require aromatic cleaners, solvents, and water, which are pollutive, waste resources, and don’t work as well. When cleaning with water, the removed load goes into the sewer system and contributes to higher COD (chemical oxygen demand) and higher BOD (biological oxygen demand) required to process your effluent. You get charged for that in your sewer or water rates.
