Chlorofluorocarbon Destruction
Six thermal oxidation (incineration) processes were approved by the Montreal Protocol for the disposal for CFCs and other ozone depleting substances. APTB has evaluated emissions from the thermal destruction of CFCs, and bench- and pilot-scale tests have been performed to identify the combustion conditions which maximize CFC destruction with minimum products of incomplete combustion (PICs) emissions. These tests have indicated a potential for formation of dioxins and furans as PICs when burning CFCs in combustion systems with refractory contaminated with copper. This work was performed in support of the United Nations Environment Programme (UNEP) and in collaboration with the Institute for Resources and Environment in Japan.
