Cars don't last forever, but thanks to a new advanced recycling technology developed by Eastman, some automotive materials can be recycled infinitely.
When vehicles at the end of life are shredded, the leftover materials known as automotive shredder residue (ASR) or "auto fluff" typically ends up in landfills or incinerators. Eastman worked with several partners on a feasibility study that demonstrated successful molecular recycling of ASR.
"Globally, we've reached a tipping point in the automotive industry," said Chris Scarazzo, global automotive segment market manager in Eastman specialty plastics. "Manufacturers have pivoted to more sustainable content, and molecular recycling can definitely play a part in that transition."
That's why Scarazzo is so encouraged by Eastman's collaboration with the United States Automotive Partnership LLC (USAMP); PADNOS, a leading mechanical recycling company; and Yanfeng, a global automotive parts supplier. The 2021 study successfully proved that a closed-loop solution is feasible for automotive plastic waste.
Though a U.S. study, the project is relevant worldwide as regulations are changing. For example, a proposal by the European Commission is pending to repeal the Directive 2000/53/EC on end-of-life vehicles (ELV) and replace it with new requirements. The new directive aims to reduce waste from ELV. Several components in the directive will increase industry sustainability, including a target that at least 25% of plastics used for automotive parts be made of recycled content.

Plastics are essential for modern automobiles - but present end-of-life challenges.
ASR is created when an automobile has reached the end of its usable life. The whole car is crushed on a giant conveyor belt and separated into different piles of materials for recycling. The metals, tires and glass that account for 80%-90% of a car can be mechanically recycled. The other 10%-20% is ASR, a mix of plastics, textiles/fibers and other materials that have historically been nonrecyclable by traditional methods - and thus destined for landfill or incineration.
