The Greentech Festival in Berlin, an event born in partnership with Audi, shows how the sustainable future of the automobile it is not just relegated to the recycling of batteries or the reduction of carbon dioxide emissions. Sustainability, to be stimulating, must respect theenvironmental field, that cheap e social. From 16 to 18 June, Audi talks about its innovative technologies through its main spokesperson, the same Oliver Hoffman, member of the Audi Technical Development Board.

Reduction of raw materials

Keynote, round tables e boot camp to learn more about how one of the adjectives that best suits the term sustainability is profitable, that is, capable of generating profits. Audi brings a recently completed project with the Institute for Technology in Karlsruhe sul to the Greentech Festival chemical recycling for the recovery of mixed plastics. Many plastic components in cars must meet precise requirements for safety, heat resistance and structural rigidity. So far, only petroleum-based materials have proved suitable in the automotive sector. Products that in most cases are difficult to recycle.

On the one hand we have the plastic pure. Material that can be disposed of mechanically and subsequently reused. And this is now reality. While on the other we have the plastic mixed. A much more difficult material to recycle to obtain a raw material suitable for industry. Thus was born a intelligent circular system that by means of a chemical-physical process called pyrolysis, transforms end-of-life plastic components such as fuel tanks, radiator grilles or wheel covers, into pyrolysis oil.

The qualities of this oil, also called tac o bio-crude, correspond to those of petroleum derivatives. While the materials produced through the bio-crude guarantee the same characteristics as the original components. A cycle that can repeat itself indefinitely. The artifacts produced from bio-crude, in fact, can be further recovered and recycled. A closed loop which allows, on closer inspection, to exploit less raw material to the advantage of overall energy balance. The economic sustainability of this research has prompted Audi to industrialize this new production cycle.

Green energy and water cleaning

The production of electricity needed to run zero-emission cars still causes CO2 emissions. That’s why Audi is already promoting thegreen electricity. Together with several partners from the energy sector, the house of the four rings plans to build new wind and solar farms in Europe by 2025 to have a total of around 5 terawattore of additional green electricity. The expansion of renewable energy sources on an industrial scale is the next step. This choice is functional to the increase in the share of green electricity with the growth of electric cars. “Our first project, a huge solar park in Mecklenburg-Vorpommern, will go into operation as early as 2022,” said Oliver Hoffmann himself.

From renewable energy to projects directly linked to the protection of the environment, or rather of our waters. The first project is called urban filter and deals with filter the microplastics where they are created. In practice, special filters placed in an urban environment trap microplastics from tire wear and other polluting particles before they are discharged into sewers and waterways along with rainwater. Staying on the water theme, Audi together with start-ups Everwave and Clear Rivers are working to rid rivers and oceans of plastic waste.

Attention to human rights

The Grenntech Festival it is also the time to prove comet la technology, in particular that linked to Artificial Intelligence, can contribute to the respect of human rights. The automotive production chain is really long and complex. For this reason, from October 2020, intelligent algorithms they analyze the news, relating to their suppliers, coming from every available source: in particular online media and social networks. This analysis, which involves 150 countries, includes both the risks associated with environmental pollution, as well as human rights violations and corruption. All information deemed relevant is transmitted to the managers of the car manufacturer.

Finally, Ecomove a new digital app to help users understand e reduce your carbon footprint resulting from mobility. The app automatically recognizes which means of transport users are using and calculates a personal mobility score. To improve this score, Ecomove jokingly motivates users to make their mobility more sustainable. Rewards in the form of trophies are used to encourage users to make positive changes in their behavior. Additionally, users can offset residual emissions via the app.
