The advancements in recycling technology, particularly in the automotive industry, have significant environmental implications. The process of molecular recycling, as demonstrated by Eastman's carbon renewal technology (CRT), addresses the long-standing issue of automotive shredder residue (ASR). By breaking down these materials at a molecular level, the CRT facilitates the creation of new polymers that match the quality of virgin materials. This innovation not only reduces the volume of waste destined for landfills and incineration but also aligns with the global push towards sustainability and circular economy principles.
From an environmental perspective, the use of recycled materials in car manufacturing can substantially lower the industry's carbon footprint. This is increasingly important as regulations tighten and consumer awareness grows. The ability to recycle plastics infinitely could transform the industry's approach to end-of-life vehicles, potentially setting a new standard for environmental responsibility in automotive manufacturing.
The collaboration between Eastman, PADNOS, Yanfeng and USAMP members like Ford, GM and Stellantis signifies a strategic shift towards sustainability in the automotive sector. The successful implementation of closed-loop recycling for ASR could lead to a competitive advantage for these OEMs by meeting not only current sustainability targets but also anticipating stricter future regulations. The directive proposed by the European Commission, for instance, sets a clear trajectory for increased use of recycled materials.
Furthermore, the ability to meet OEM standards with recycled components may result in cost efficiencies and supply chain resilience. As the industry moves towards electric vehicles, which require lighter materials, the demand for high-performance plastics is expected to grow. The innovation by Eastman could thus play a critical role in meeting these new material requirements while adhering to environmental regulations.
The successful molecular recycling of ASR by Eastman presents a significant opportunity for supply chain optimization within the automotive industry. By converting end-of-life vehicle materials back into usable resins for new parts, the industry can reduce its reliance on raw material extraction and minimize the volatility associated with commodity prices. This closed-loop system also aligns with the broader industry trend towards sustainable supply chain practices.
The collaboration between recyclers, suppliers and manufacturers demonstrates the importance of integrated supply chain strategies to achieve sustainability goals. An efficient recycling infrastructure could serve as a model for other sectors and has the potential to influence global supply chain standards. Additionally, the ability to produce components that meet the stringent requirements of OEMs ensures that quality is maintained, which is essential for consumer trust and brand reputation.
A key result: Plastic auto waste met OEM standards for new automobile parts.

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
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
Plastic is essential in modern automobiles because it is light, strong and durable. The industry needs alternative materials to help lower greenhouse gas emissions and reduce carbon footprints. Lightweighting improves fuel economy, and the rise of electric vehicles creates further need for light but strong materials to offset the weight of heavy batteries.
"Modern cars are made with approximately
Molecular recycling - the solution to deliver circularity.
Eastman's molecular recycling technologies can revolutionize recycling because they process hard-to-recycle plastics like those in ASR. These technologies break down plastic waste at the molecular level, so these recycled materials can be built back into new polymers that are indistinguishable from virgin materials with no trade-offs in performance or safety.
Eastman's carbon renewal technology (CRT) can recycle almost any plastic and was used to demonstrate closed-loop recycling for ASR. In the project, PADNOS supplied ASR as feedstock for Eastman's recycling process. Using CRT, Eastman converted the ASR into materials used downstream in the production of new plastic resins. Finally, Yanfeng molded Eastman resins into new automotive parts that met a variety of requirements established by three OEMs: Ford, GM and Stellantis - all members of USAMP.
The results show what's possible.
This study underscored the value of collaboration for a more sustainable future. Both mechanical recycling and molecular recycling are needed and must work together to deliver a recycling infrastructure for the modern age.
"The collaboration on this project is indicative of the work that is needed to create closed-loop and circular-economy solutions," said Kari Bliss, principal of sustainability at PADNOS. "Our purpose statement is on full display with this project - to continue to find ways to innovate, lead and make a positive impact in this world. We are proud to be the mechanical recycler involved in this complex endeavor, which is the first of its kind in North America."
