For many experts the world over, our production processes represent a model of efficiency. Why? Because in the early 1990s – when the company was restructuring – we introduced streamlined processes based on the Japanese model. We adapted these methods and ever since have continually and very successfully optimised them at our factories. Put simply, it is about focusing on added value and eliminating waste in the shape of unproductive time, unused storage space and surplus materials.

In line with our environmental efforts, Porsche wastes nothing that is used in vehicle production, whether it is water, energy or raw materials. This is particularly the case at Zuffenhausen, a site with a high level of social responsibility as it borders on a residential area. This automatically makes the implementation of specific measures and objectives extremely important:

• Reducing the amount of waste
• Optimising the treatment of effluents
• Reducing CO2 emissions in all areas of production
• Implementing wastewater treatment measures
• Adhering to environmental regulations
• Promoting internal and external communicationon environmental issues

Power and water consumption per vehicle at Zuffenhausen

During engine manufacturing, all swarf is made into briquettes and completely recycled. The first major engine tests are performed cold, so no petrol is consumed and for the bodywork we are increasingly switching to adhesives technology which increases vehicle rigidity whilst reducing fume emissions during welding. In the paint shop, water-based paints are used which significantly reduces solvent use. Our vehicles feature absolutely no asbestos and no parts containing CFCs. Just a few examples of how green our production processes are.
