The week is coming to an end and so is our series of posts about Audi’s trailblazing logistics program. In case you missed the first two parts you can read them here: Audi’s Green Logistics Program Part 1 and Audi’s Green Logistics Program Part 2.
Intelligent – the energy supply
AUDI AG is also focused on resource efficiency when it comes to the supply of energy. Beginning in spring 2011, the use of waste heat from Ingolstadt’s waste utilization plant and from the Petroplus refinery will double from 60,000 to 120,000 megawatt hours per year. This represents potential CO2 savings of around 26,000 tons. A further expansion which will use 200,000 megawatt hours of waste heat is planned. The plant in Neckarsulm is also supplied with district heat.
In Ingolstadt, Audi has for years been producing roughly 100,000 megawatt hours of heat in its own highly efficient power-heat-cooling trigeneration plant, which also produces electricity and cooling energy. The remainder of the heat requirement is met using natural gas-fired boilers. Thermal wheels are used in many areas of the Company to recover heat; many hundreds of these units are deployed in Ingolstadt. The use of 19 heat recovery systems in the paint shop, for example, extracts approximately 35,000 megawatt hours per year, which corresponds to a CO2 reduction of around 7,000 tons.
Audi is also driving progress in the field of photovoltaics. The carmaker has made the roofs of numerous factory buildings at the Ingolstadt plant available to Munich-based Green City Energy. The photovoltaic modules installed there over an area of 11,600 square meters (124,900 square feet) produce more than 1,000 megawatt hours of electrical energy a year. An expansion of the photovoltaic surface area, including to the second German Audi site in Neckarsulm, is currently under review. And just a few months ago, Automobili Lamborghini, a subsidiary of the Audi Group, took a 17,000 square meter (183,000 square feet) solar power plant on line.
Beyond the factory gates – the Oak Forest research project
At Audi, environmental protection does not stop at the factory gates. In collaboration with the Bavarian State Forest Service and the Technical University of Munich, the Company has launched the “CO2 Reservoir Oak Forest” research project in the vicinity of the Ingolstadt plant. The project is focused on the scientific investigation of biological and ecological interrelationships. Audi planted roughly 36,000 Pendunculate Oaks for the project in 2008. A second trial site near the Györ production site in Hungary was planted with more than 13,000 oaks. Other sites are currently in planning.
The Company’s commitment is also manifest in the newly established Audi Environmental Foundation, which has been endowed with five million euros. The foundation’s aim is to protect the natural livelihood of people, animals and plants. It will fund measures and research activities that encourage the development of environmentally compatible non-automotive technologies, promote environmental education and contribute to a sustainable human/environment system.
Universal – environmental management at Audi
Sustainable business practices are an integral component of the Audi corporate strategy, in which environmental protection and innovation are linked. Audi has been awarded the European Union’s seal for outstanding environmental protection.
The Company is also involved within the framework of the 3rd Bavarian Environment Pact, which is dedicated to environment-friendly economic growth. Particularly high value is placed on the sharing of information with suppliers. The greater use of environmental protection strived for at the suppliers gives Audi greater influence on indirect environmental aspects by enabling the early development of holistic solutions.
The Audi Group is considered both in Germany and abroad to be one of the pioneers of site-specific environmental protection. EMAS (Eco Management and Audit Scheme), the demanding environmental management system of the European Union that far exceeds standard requirements, was installed in Ingolstadt (1997), Neckarsulm (1995), Györ (1999), Brussels (2002) and Sant’Agata Bolognese (2009), and has been steadily optimized in the interest of continuous improvement.
The Ingolstadt, Györ, and Sant’Agata Bolognese sites are also certified to the global standard DIN EN ISO 14001, which ensures continuous improvement of environmental protection performance. Furthermore, the environmental management system at the Ingolstadt plant has been certified to the European standard DIN EN 16001. This stipulates particularly stringent requirements for the steady and systematic reduction of energy consumption. The Audi plant in Ingolstadt was the first automobile plant to be awarded this certificate.
To conserve water resources, Audi is making greater use of rainwater at the Ingolstadt plant, where it is gathered over an area of 450,000 square meters (4,843,800 square feet), collected in five retaining pools and two storage sewers and forwarded to a treatment plant. The pools supplied more than 235,000 cubic meters (8,298,900 cubic feet) of process water in 2009.
Innovative and efficient – the products
When it comes to the products, Audi is further expanding its Vorsprung durch Technik with highly efficient TDI, FSI and TFSI engines and many new solutions from the modular efficiency platform. The lightweight construction of the Audi Space Frame reduces vehicle weight, and the aluminum bodies also enjoy major advantages in the overall energy balance and with recycling.
Audi is also concurrently hard at work on the development of alternative drive systems, with the Audi Q5 hybrid scheduled to debut next year. For a glimpse at the brand’s interpretation of the sustainable mobility of the future, one only need look at the Audi e-tron family, which features tailored concepts for each segment.
