Basf is breaking new ground in plastic waste recycling with its ChemCycling project. Chemical recycling provides an innovative way to reutilize plastic waste that is currently not recycled, such as mixed or uncleaned plastics. Depending on the region, such waste is usually sent to landfill or burned with energy recovery. But chemical recycling offers another alternative: Using thermochemical processes, these plastics can be utilized to produce syngas or oils. The resulting recycled raw materials can be used as inputs in Basf’s production, thereby partially replacing fossil resources.

Basf has for the first time manufactured products based on chemically recycled plastic waste and is thus one of the global pioneers in the industry. “A responsible use of plastics is crucial to solve the world’s waste problem. This applies to companies as well as to institutions and consumers. With chemical recycling we want to make a significant contribution in reducing the amount of plastic waste,” said Martin Brudermüller, Chairman of the Board of Executive Directors and Chief Technology Officer (CTO) of Basf. “With our ChemCycling project, we are using plastic waste as a resource. In this way, we create value for the environment, society and the economy. We have joined forces with partners throughout the value chain to establish a working circular model,” said Brudermüller. Basf is collaborating closely with its customers and partners, which range from waste management companies to technology providers and packaging producers, to build a circular value chain.

From waste to cheese packaging and fridge components

Basf is already developing pilot products, including mozzarella packaging, refrigerator components and insulation panels, with 10 customers from various industries. Manufacturing products that meet high quality and hygiene standards - which are specifically required for food packaging for example - is possible because the ChemCycling products supplied by Basf have exactly the same properties as products made from fossil resources. Stefan Gräter, head of the ChemCycling project at Basf, sees great potential: “This new way of recycling offers opportunities for innovative business models for us and our customers, who already place great value on products and packaging made from recycled materials but who cannot or do not want to make any compromises when it comes to quality.” As a next step, Basf plans to make the first products from the ChemCycling project commercially available.

Technological and regulatory challenges

Both the market and society expect industry to come up with constructive solutions to deal with plastic waste. Chemical recycling is an innovative complement to other recycling and waste management processes. “We need a wide range of recovery options for plastic waste, since not every solution is suitable for each type of waste or possible for each product application. The first choice should always be the solution that performs best in a life cycle assessment,” explained Andreas Kicherer, sustainability expert at Basf.
