Dry ice blasting is a relatively new cleaning method used to remove mold from walls and other surfaces. It works on the same principles as sand blasting, or blasting with other mediums such as soda or plastic beads that are fired under pressure by a jet of compressed air onto the surface that needs to be cleaned. However, dry ice blasting offers many benefits over these methods and other chemical methods of removing mold and other surface contaminants from substrates.
Kennedy and Sugar make the claim in ‘A low carbon infrastructure plan for Toronto, Canada,’ published in the latest issue of The Canadian Journal of Civil Engineering. The paper aims to show how cities can make a positive difference using realistic, achievable steps. Their research shows that it is technically possible for cities to reduce their greenhouse gas emissions by 70 per cent or more in the long-term.
