Since April 1994, the company waste water at the Mertingen site has been cleaned physically, microbiologically and chemically by a waste water treatment plant. Over the years the plant has been systematically updated and in 2004 expanded to include cutting-edge expertise. For years, we have been undercutting the legally required discharge limits considerably.
