Audi, this is how the recycling of plastic from old cars works

The path to sustainability of Audi also goes through the use of recycled and recyclable materials inside its new cars. On this theme, the house of the 4 rings has told a novelty; interesting that concerns its electric SUV Q8 e-tron. In fact, the automaker has decided to use recycled plastic for the seat belt buckles of its new model. Audi points out that the plastic of the new buckles, obtained by chemically recycling automotive waste, is; the result of an innovative industrial process developed with the specialist LyondellBasell. It is a new step forward in getting to use an amount of water. growing recycled plastic inside its cars.

How does this chemical recycling process work?

RECYCLED PLASTIC

By entering more; specifically, the house of the 4 rings says that this chemical recycling process, the result of a project supported since 2021, provides for the non-repairable automotive plastic components to be separated from foreign materials, such as clips metals, before being crushed and transformed into pyrolysis oil.

The qualities; of this oil, defined as bio-crude, correspond to those of petroleum derivatives and the materials made using pyrolytic oil guarantee the same characteristics as the original components. In addition, anything produced with bio-crude can be be further recovered and recycled.


Audi goes on to state that, subsequently, the ;pyrolysis oil is introduced into the production process of the new plastics according to a defined approach of “mass balancing”. At least 70% of the granulate destined for the production of seat belt buckle covers is so; made up of pyrolysis oil. A percentage certified by ecocycle, an independent agency that monitors the replacement of the fossil resource with the secondary product.

But this is the only way to achieve this. just the beginning. In fact, Audi is aiming to generate pyrolysis oil in quantities in the short term. such to completely exclude the use of petroleum derivatives, recovering automotive waste that would otherwise be difficult to reuse. Pyrolysis oil can replace crude oil as a raw material in the production of plastic components with costs comparable to what is required by the mere mechanical disposal of waste.
