Starting up under the Shadow  of Corona

Plastic waste in the sea has been shaping the negative image of the industry for several years. Various initiatives and mergers of companies have therefore launched projects to tackle this Ocean-bound Plastics (OBP). Components made of OBP could become a symbol for a sustainable use of plastics.

Polymer materials, including synthetic polymers, have a bad reputation. These image problems do not just arise from the current environmental debate but also have earlier origins. In the past, too, polymer materials were subject to unjustified criticism. This often stemmed from non-scientists and frequently betrayed a lack of scientific knowledge.

On the Image of Plastics and their Responsible Use

The increasing volume of plastic waste and the growing pollution of the oceans by such waste have brought the sustainable handling of plastic products into the focus of society and politics. Both recycling and bioplastics can be a part of a strategy for greater sustainability, but they are not free of side effects. In order to avoid irrational decisions, it is important to assess their effects comprehensively.

Why Recycled Films Are Not Necessarily Sustainable

The beneficial processing and service properties of plastics are increasingly determining the ecological fate of the world. The plastics industry has now realized that it is not enough to put the blame on consumer behavior. As K 2019 showed, numerous initiatives and technical developments are paving the way for the urgently needed establishment of a circular economy.

The Dawning of the Circular Economy

There is little doubt where we are heading: multilayer packaging will have to become easier to recycle – but what does that mean for the technology? And what solutions will the market need and accept? Manufacturers of branded goods are not the only ones who will have to rethink their specifications.

By means of high-performance processes, chemical recycling converts plastic waste into high-grade material for new plastic products. Moreover, freedom of design results by selecting a suitable process and the matching waste material. Hereby, the right combination permits customized polyols to be created for the desired application area.

Currently, recyclates are in high demand, including the automotive industry. Previously, component suppliers had reservations about using recyclates in safety-related areas, because mechanical properties varied too widely. Now, materials producer JSP has developed an expanded polypropylene with 25 % recyclate content precisely for these application areas. But to ensure high quality, close cooperation with the recycling company is essential.

“Chemical Recycling Is Not yet Ready for Commercial Use”

From 2025, every new vehicle from Volvo will contain 25 wt. % of recycled plastics. In this way, the car manufacturer aims to take not only itself but also its supply chain in the direction of recycling. Can it succeed? The first prototype launched by Volvo has provoked hot debate.

KIT and Audi Launch Pilot Project for Chemical Recycling

Closed loop for plastics from the automotive industry: waste from engineering plastics is processed into pyrolysis oil that can be used for new components.

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

“Recycling automotive plastics has not yet been possible for many components. That is why we are doing pioneering work here together with Audi,” says Professor Dieter Stapf, Head of KIT’s Institute for Technical Chemistry, who also is involved in the Thinktank. “If we want to close these loops, we need to develop suitable methods.” So far, chemical recycling has been the only method that can be used to convert such mixed plastic wastes into products, whose quality matches that of new products.

As a result, a wider range of plastics can be recovered, Stapf says. “Such closed material loops save valuable resources, because less primary material is required. This, in turn, saves energy and costs – and is beneficial to the environment,” says Dr. Rebekka Volk from KIT’s Institute for Industrial Production.

Pilot Project of the Thinktank Industrial Resource Strategies

The pilot project “Chemical Recycling of Plastics in Automotive Engineering” is conducted by the Thinktank Industrial Resource Strategies that has been established at KIT by the Baden-Württemberg State Government together with industry and the support of academia. “Responsible use of resources is the joint obligation of industry, science, and politics. The Thinktank pools all competencies to master this big challenge and to serve society and the environment,” says Professor Thomas Hirth, KIT Vice-President for Innovation and International Affairs and Spokesperson of the Thinktank.

“Chemical recycling can be a major component of comprehensive plastics recycling. This makes it an interesting proposition for the automotive industry. The Thinktank and Audi are jointly addressing a central issue of making automobiles more sustainable and environmentally friendly in future irrespective of their type of powertrain. The Thinktank is focused on a holistic view of raw material loops,” says Dr. Christian Kühne, Managing Director of the Thinktank.

Audi is among the first automotive manufacturers testing this recycling method in a pilot project with plastics from automotive engineering. “We want to establish smart circular systems in our supply chains and make efficient use of resources,” says Marco Philippi, Senior Director Procurement Strategy of Audi.

“Chemical recycling has a great potential for this: If plastic components can be produced from pyrolysis oil instead of petroleum, it would be possible to significantly increase the proportion of sustainably manufactured components in automobiles. In the long run, this method can also play a role in end-of-life vehicle recycling.”

Pyrolysis Process for More Sustainable Products

The “Chemical Recycling of Plastics in Automotive Engineering” pilot project targets the creation of smart circular systems for plastics and establishing this method as a complement to mechanical recycling and replacement of energetic recovery. Partnering with KIT’s Thinktank, Audi intends to initially test the technical feasibility of chemical recycling and to evaluate the method in terms of its economic efficiency and environmental impacts. For this purpose, the company provides plastic components that are no longer needed, such as fuel tanks, wheel trim parts, and radiator grills, from Audi models returning from the German dealership network, for example.

The plastic components are processed to pyrolysis oil by chemical recycling. In the medium run, components based on pyrolysis oil can be used in automobiles again. If technical feasibility will be demonstrated, Audi will industrialize the technology and progressively apply it to more and more components.

Research and technology development for sustainable circular economy are major topics at KIT. “We are systematically studying the potentials of pyrolysis and how pyrolysis processes have to be designed on a large scale for maximum recycling of resources,” Stapf says. Chemical recycling of plastic wastes can help make modern products more sustainable and prevent greenhouse gas emissions.
