Ozone-eating chemical to be banned on Jan 1
China will ban a chemical foaming agent, used to make polyurethane insulation, that can deplete Earth’s ozone layer. Affected enterprises are asked to switch to low-carbon and more environmentally friendly replacements, the country’s top environmental watchdog announced on Oct 24. Starting Jan 1, manufacturers of refrigerators, refrigerated containers and electric water heaters will no longer be able to use foam insulation made with the chemical — known as HCFC-141b — according to a statement from the Ministry of Ecology and Environment. China began to weed out HCFCs, a category of ozonedepleting substances, in the polyurethane foam industry in 2011, shifting to lower-carbon and more environmentally friendly alternatives.
