Successful Pilot Project Overview
Porsche AG, in collaboration with BASF SE and technology partner BEST Bioenergy and Sustainable Technologies GmbH, has successfully completed a pilot project aimed at recycling mixed waste from end-of-life vehicles. This initiative focuses on automotive shredder residue (ASR), a complex mixture of plastics, foams, films, and paint particles that are typically difficult to recycle. The project demonstrates the potential of gasification, a form of chemical recycling, to convert these mixed waste streams into valuable raw materials for new automotive components, such as polyurethane foam for steering wheels.
Innovative Recycling Process
The pilot project marks a significant advancement as it is the first instance where fossil-based inputs have been entirely replaced by a combination of automotive waste and biomass through a gasification process. This method allows for the transformation of ASR into synthesis gas, which can then be processed into new plastics, effectively closing the material loop in the automotive industry. The gasification technology employed was adapted by BEST GmbH, which has previously focused on converting biomass into chemical raw materials.
Goals and Future Implications
Porsche aims to enhance the circular economy within its manufacturing processes by increasing the proportion of recycled materials in its vehicles. The pilot project serves as a critical step in evaluating the viability of ASR as a future source of recyclate, potentially reducing reliance on primary materials. Dr. Robert Kallenberg, Head of Sustainability at Porsche, emphasized the project's role in developing new recycling technologies and increasing access to previously unusable recyclate sources.
Industry Perspectives
Martin Jung, President of BASF’s Performance Materials division, highlighted the importance of integrating various recycling technologies to meet sustainability targets. He noted that while mechanical recycling is prioritized, complementary methods like chemical recycling are essential for managing waste that cannot be mechanically processed. This approach aims to reduce the volume of plastic waste that ends up in landfills or is incinerated.
Criticism & Opposition
Despite the advancements, some critics argue that the reliance on chemical recycling could detract from efforts to improve mechanical recycling processes. Concerns have been raised regarding the environmental impacts of gasification and the need for a comprehensive regulatory framework to support diverse recycling technologies.

- “We are convinced that complementary technologies such as chemical recycling, which includes pyrolysis, depolymerization and gasification, are necessary to further promote the circular economy and reduce the plastic waste that still ends up in landfills or is incinerated today," explains Dr.” — Martin Jung, President of BASF’s Performance Materials division
- “This form of chemical recycling has great potential for converting complex, mixed waste streams into new, valuable raw materials. It thus represents a sensible alternative to waste incineration.” — Dr. Matthias Kuba, Area Manager Syngas Platform Technologies at BEST GmbH
What's Next
The completion of this pilot project aligns with broader industry trends, including the European Union's upcoming regulations mandating recycled plastic quotas in new vehicles. The success of this initiative may pave the way for further research collaborations, such as the Global Impact Coalition's partnership with ETH Zurich and major chemical companies to explore the feasibility of gasification technologies for complex waste streams.
