Porsche, BASF and BEST successfully complete chemical recycling pilot project

-

Porsche AG and BASF SE, in cooperation with the technology partner BEST Bioenergy and Sustainable Technologies GmbH, have successfully completed a joint pilot project for the recycling of mixed waste from end-of-life vehicles. The project demonstrates the recyclability of high-performance plastics contained in the so-called automotive shredder residue (ASR) - a mixture of shredded parts such as foams, plastics, films and paint particles, mainly from end-of-life vehicles. Currently, the complex mixture of a variety of materials can only be thermally recovered.



Porsche aims to promote the #circulareconomy in the manufacturing of its vehicles and has set itself the goal of increasing the proportion of #recycled materials in its vehicles.

Gasification is a form of chemical recycling that can be used to convert mixed waste streams into valuable new raw materials, for example for plastics production. In the future, it could be an alternative to the current thermal recovery process and complement Porsche's circular economy strategy. Chemical recycling enables the processing of plastic waste that cannot be mechanically recycled for technical, economic or ecological reasons.


The pilot project serves to evaluate the potential of #automotiveshredder residue as a future source of recyclate. The completed trial used a recycling process that, for the first time, completely dispenses with fossil-based input and instead uses bio-based raw materials such as wood chips in addition to automotive waste. Advanced gasification technology is used to convert plastic waste into synthesis gas at high temperatures.


Within the BASF production network that integrates this synthesis gas, new plastic is produced for component manufacturers a so called polyurethane formulation. As part of the pilot project, the formulation was used for new steering wheels. The recycled raw material was attributed to the new plastic using a mass balance approach.


Pilot projects like these allow us to evaluate how we can further develop the circular economy as a sustainability field at #Porsche and how we can anchor chemical recycling in our strategy in the long term. We are testing new recycling technologies with our partners in order to increase recyclate quotas, gain access to previously unusable recyclate sources and evaluate new processes for waste streams that are currently being thermally utilised.’


#BASF offers a wide range of recycling solutions and we strongly believe that different recycling technologies have to add up to a wide spectrum to achieve recycling targets. We prioritize #mechanicalrecycling and continuously improve its efficiency. The type of #waste and the level of sorting determine which technology is most suitable. We are convinced that complementary technologies like #chemicalrecycling are needed to deal with the remaining waste that is still incinerated today.

Today's KNOWLEDGE Share : What Is Going Wrong in UK Plastics Recycling?

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
