CO2 Snow Environment Concern is growing that CO2 is a green house warming gas. The snow cleaning process does not contribute new CO2 to the atmosphere. The CO2 gas used for cleaning is a byproduct of other industrial processes and it can be recycled. The contaminant removed will be concentrated at the location where the snow flakes sublimate. This facilitates waste collection and disposal. Waste disposal requirements depend on the type and amounts of soil removed. The process is not designed for heavy soil loadings, therefore waste quantities should be minimal.
