01 Corporate Social Responsibility | Report, June 2008 | Environmental protection, production and sites Solvent-free cleaning agent Throughout its manufacturing process, L’Orange uses a solvent-free bio-cleaning agent that removes oil residues and grit with the help of microorganisms. In comparison to cleaner solvents, it is more efficient, non-combustible and has no hidden health risks. L’Orange has more than halved its solvent use. Components and tools are cleaned in special washbasins at 37 degrees (the optimum temperature for the microorganisms). Water protection Our aim is to use water as sparingly as possible and protect water from impurities as securely as possible. Wherever possible, we use circulation systems to reuse water. In Friedrichshafen Plant 2, rainwater from the eastern end of the site is cleaned through a gravel filter in a bio-purification plant for surface water. First, the rainwater is collected and fed into a forebay. Light materials that rise to the surface are retained there, while heavy materials and dirt particles sink to the bottom of the forebay. The water then runs through a gravel bed with reeds growing in it. The roots of the reeds provide further natural cleaning and it is only then that the water flows out into Lake Constance. This cleaning process achieves a similar result to that of a conventional rainwater purification basin, plus it saves energy and money. MTU also uses water from Lake Constance at Plant 2 to cool the test benches and machine tools. In order to savely avoid impurities, the installed monitoring systems are state-of-the-art. Tognum is currently working with energy suppliers on a concept that will enable the use of waste heat from the engine test benches to heat communal buildings in the neighbourhood. Soil protection For Tognum, the protection of soil and groundwater is one of the most responsible tasks related to environmental protection. The top objective is not to generate any impurities at all in the first place. Technical devices such as collecting basins, double-wall containers, sealed flooring and leakage warning probes can be used to prevent liquids that are hazardous to waters from entering the soil. At the Friedrichshafen site (which is almost 100 years old), the company has systematically detected all pollution and thereby ensured that there can be no contamination of the groundwater.

01 Corporate Social Responsibility | Report, June 2008 | Environmental protection, production and sites Waste avoidance Avoidance and reuse are better than disposal. That's why the reprocessing and recycling of raw, auxiliary and operating materials has been common practice for years. In order to prevent waste being generated at all, the company implements innovative technical processes and environmentally friendly production planning. The Tognum companies use returnable packaging and thus do not allow large volumes of wooden and cardboard waste to accumulate in the first place. The most crucial contribution is the delivery of vendor parts to the warehouse and assembly plants. Tognum specifies the use of returnable packaging in the container instructions and supplies such packaging, e.g. metal pallets. Returnable packaging is also used when sending finished parts for engines and drive shafts from Germany to assembly sites in the USA and Asia. When dispatching drive shafts supplied by Rotorion to automotive manufacturers in large numbers, special frames are used and these can be sent back. Traffic For parts transportation and the use of cars for business trips, Tognum uses particle filters and economical cars and lorries that comply with the EURO 5 emissions standard. The development of a car-sharing system means that approx. 15 percent fewer cars are needed. The carpool in Friedrichshafen comprises approximately 400 cars, lorries and vans. All diesel vehicles (including management vehicles and vans) are equipped with a diesel particle filter and thus achieve the best possible emission values. In 2008, two lorries will be purchased with Bluetec catalytic converters in compliance with the EURO 5 emissions standard. In the future, parts transportation between company sites will be carried out with these lorries. For urban traffic, Tognum has purchased ten Smart cars that are equipped with a start/stop function and therefore use approximately eight percent less fuel. Tognum promotes the formation of driving communities for the journey to work and for business trips. With the support of the company, a group of employees and works council members runs a bicycle group that provides free rental bikes for staff. The activities of the group include improving the infrastructure relating to cycling, managing changing rooms and lobbying for cycle paths. MTU Environmental Foundation As its site lies directly on Lake Constance, MTU has an especial responsibility for and a longterm interest in the protection of the ecological diversity of the lake. The company provides permanent support for environmental and nature conservation projects with the aim of maintaining the natural living conditions of plants, animals and humans in and around the lake. In 2004, the MTU Environmental Foundation was created for this purpose, with a foundation capital of more than half a million euros. The foundation supports measures to protect flora and fauna around Lake Constance, e.g. the 'Fischfreundliche Renaturierung Bodensee' ['Fish-friendly renaturation of Lake Constance'] research project. As an expert consultancy committee, the foundation's advisory board consists of highly skilled specialists from official bodies and the Baden-Württemberg State Institute for the Environment, Measurements and Nature Protection. 7
