A large number of components in automobiles are made from plastics. They have to meet exacting safety, heat resistance and quality requirements. That is why, so far, only petroleum-based materials have been suitable for manufacturing plastic components in automobiles that are subjected to particularly intensive wear. Such materials are not recyclable in most cases. Whereas plastics of the same type can often be mechanically recycled, recycling of mixed plastic waste poses a major challenge. Audi and the Karlsruhe Institute for Technology (KIT) are therefore launching a pilot project for chemical recycling as part of the “Industrial Resource Strategies” THINKTANK in order to feed such mixed plastic fractions back into a resource-conserving circular system.
