US: A study conducted by researchers at the Massachusetts Institute of Technology (MIT) has found that spray foam insulation applied to walls prior to the entry into effect of the Montréal Protocol banning chloroflourocarbons CFCs) is acting as a ‘CFC bank’ from which environmentally degrading chemicals continue to leach into the atmosphere.
MIT Lee and Geraldine Martin Professor of Environmental Studies Susan Soloman recommended that all such banks be ‘recovered and destroyed.’ “Before demolishing a building, you can take careful measures to recover the insulation foam and bury it in a landfill,” she said.
