Mahle has received the Partslife 2015 Environmental award for its central filter system for cooling lubricants at the Leibertingen/Germany location. This system sets new standards in economic efficiency and ecology.
The jury selected the project on account of the high degree of energy savings and the significantly improved waste balance sheet. Olaf Henning, Member of the Management Committee and Managing Director of Mahle Aftermarket GmbH, accepted the environmental award on behalf of the Mahle Group on 17 June 2015 at the Partslife anniversary celebration.
“For Mahle, environmental awareness is not just about supporting the development of the automotive industry in terms of CO2 reduction and energy efficiency in the engine. We believe that we should also set a good example in the manufacturing of our own products,” explained Olaf Henning during the award ceremony.
“The new pump and filter system operates centrally and is fully automated. Virtually no waste is now produced, thereby significantly improving the overall waste balance. Thanks to this system, energy costs can be reduced by approximately 20 to 30 per cent in comparison with our individual systems. Moreover, we no longer need additional filter aids thanks to the use of energy- efficient, controlled pumps and achieve cost savings of several thousand euros every month by briquetting the grinding sludge”, says Martin Hack, production supervisor and environmental management officer at the Mahle Leibertingen location. “The previous solution required relatively intense monitoring for the decentralised units, and the work was not particularly popular with the employees. They are pleased that they can now focus on what is essential.”
At the Mahle Leibertingen location, the group manufactures components made from hardened roller bearing steel. The accuracy of the machining processes is—particularly in the grinding operation—dependent on a clean cooling lubricant and optimised chip disposal. To maintain and clean the grinding oil, the Mahle Leibertingen plant therefore uses the award-winning central system, which has been in series operation since July 2014.
