- 27 Components with recyclatant part: Sustainable materials in the Elektro-SUV
- Predictive, clever and economical handling of resources
Audi focuses on the topics of climate protection and sustainability stronger than ever – including the predictive and economical approach to resources. With the help of new processes, materials and new technologies, especially new vehicle models, in particular the electrified fleet, should be produced as climate-neutral and sustainably.
So the Ingolstadter already manufactures the Q4 E-tron and the Q4 Sportback E-tron For the markets of Europe and the USA Bilanziell Climan-neutral. In the event of emissions the mark “avoid and reduce”. The Volkswagen plant in Zwickau, – where the Q4 is built – is the largest and most powerful e-auto factory in Europe and relates eco-electricity. The manufacture of the battery cells is energy-intensive – that is why Audi also committed its cell suppliers to use only “green” electricity in production.
All emissions that can not be avoided, according to companies, are offset by climate protection measures with carbon credits and are also certified by the Non-Profit Organization “The Gold Standard” or “Verified Carbon Standard”. The Q4 E-tron Will give the customer according to CO2-neutral. When the car has reached the end of its life, its battery in Second-Life concepts is to be used or – if this is no longer economically possible – to be used sustainably by recycling as a source of raw materials. First pilot and research projects in this area are already successfully completed.
In addition to the balance sheet CO2-neutral production, Audi will continue to be the use phase of the E-tron-Fleet in Europe green. In the home garage, customers of the Q4 should E-tron already worldwide eco flow – for example, from Elli, a subsidiary of the Volkswagen Group providing the certified natural stream. For the shop on the way networks like ionity also offer regenerative electricity..
For all vehicle projects, Audi commands together with its suppliers for responsible action. Since 2017, the company has reviewed its partners with a sustainability rating – it aims to ensure resource-saving production and compliance with social standards. Since 2019, this rating has been a mandatory selection criterion since 2019.
27 Components with recyclatant part: Sustainable materials in the Elektro-SUV
Sustainability and resource conservation also play an important role in the overall vehicle. In the electro SUVs, 27 components with recyclatant. The exterior is components such as the mounting carrier – a component that needs to meet particularly high requirements for mechanical properties. In addition, the headlamp recordings, the wheel skates, the fender covers, the bottom trim and the wheel spoilers consist to a large proportion of secondary raw materials.
In the interior, recyclates are used in insulation and damping materials. In addition, many visible surfaces contain recycled materials. These include, for example, the floor covering and parts of the luggage compartment lining. In the Interior S Line, the customer receives the microfiber material Dinamica, which serve in conjunction with faux leather as a cover for the sports seats. Dinamica consists of 45 percent of polyester fibers. They are recycled from recycled PET bottles, former textiles or fiber residues.
The fabric pulse, also combined with imitation leather, contains about 50 percent recyclatant. For a seat set, around 26 pet bottles of 1.5 liters are processed in a complex process to yarn. The final result is a material that reaches visually and haptically equal quality standards as a classic textile cover. The decorative insert technical tissue for the instrument panel, which follows shortly after the market start, also partially consists of recyclat material.
Predictive, clever and economical handling of resources
But not only in the Q4 value is placed on recycled materials. According to a current press release, therefore in the electric Gran Turismo E-tron Gt quattro old fishing nets processed. Ground carpet and floor mats are also made of Econyl. A material that consists of 100 percent recycled nylon fibers. They come from production waste, cloth and carpet residues or plastic waste from the oceans. In addition, according to Audi, a 20-inch rim of the Audi E-tronGT made of CO2-reduced aluminum made. Speaking of: Aluminum is an important raw material in automotive production.Did you know that 2019 in Germany around 507.000 tonnes of primary aluminum were made? For this purpose, about 7.6 terawatt hours of energy were necessary – slightly less than a nuclear power plant generated per year. Therefore, it is worthwhile to collect aluminum blend and melt again. Audi has established the so-called “aluminum closed loop” in the Neckarsulm site since 2017 and now also implemented in Ingolstadt (2020) and Győr (2021). Only with this optimized production process alone in 2020 165 should.000 tonnes of CO2 have been avoided.
The topic “Second Life” is a way to become climate-neutral for used battery modules. So two used E-tron-Dealer battery modules in Uttar Pradesh (India), even at night to have electricity and work. The German-Indian Startup Nunam, which produces the memory for this, is funded by the Audi Foundation for the Environment. And also the memory from used lithium-ion batteries of Audi developing vehicles are reused. This happens, among other things, on the Berlin Euref campus. With a capacity of 1.9 MWh, therefore, the entire campus could be supplied with electricity just under two hours. But of course, the topic of electromobility makes only really sense if it is preferably used eco flow for production and charging. Here, too, the VW Group expands his commitment significantly. Therefore, at the Audi site GyOr in Hungary, 36.400 solar cells on an area of about 22 football fields for producing 9.5 gigawatt hours per year.
