In our plant in Öhringen, Germany, a package of measures enabled us to save valuable resources - 178 tons in total - in 2005 and 2006. For example, the waste produced during startup of injection-molding machines was decreased, the number of defective plastic parts was systematically reduced, and sprues of injection-molded parts were reground directly at the machine and added to the fresh resin. After customer approval, we were also able to use more than 200 tons of recycled resin in place of new resin.

Energy management system established for german plants
In view of the rising energy costs and the general unpredictability of German energy policy, MAHLE launched a systematic concept, consistent across the Group, for an in-house energy management system generating potential savings of 10% per year.
