    Chemists have invented a new class of catalysts that can destroy some of the worst pollutants before they get into the environment. The invention of TAML catalysts is just one of the many achievements of green chemistry, which strives to develop products and processes that reduce or eliminate the use and generation of hazardous substances. TAMLs can prevent staining by attacking dyes after they detach from one fabric but before they attach to another. The effectiveness of Fe-TAMLs at decolorizing fragments at two pulp mills in U.S. and one in New Zealand have been tested. Fe-TAMLs reduced the staining of the water by up to 78 percent and eliminated 29 percent of the organochlorines.
