Apidic acid (AA) manufacture results in the production of ca. 1 mole of nitrous oxide (N2O) per mole of AA. Emissions of N2O by the AA industry currently account for about 5-8 percent of the worldwide anthropogenic N2O emissions (after accounting for N2O abated by some manufacturers). Even though this N2O does not make a major contribution to global warming and ozone depletion, major AA producers worldwide have agreed to substantially reduce these emissions by 1996-98. Producers have formed an inter-industry group to share information on technologies being developed for N2O control. Technology options being studied by DuPont (and by others) include thermal destruction, recycling, and catalytic decomposition.
