Finland’s Innovative Approach to Renewable Plastics

In recent years, Finland has emerged as a leader in sustainable industrial practices, particularly in the field of plastics. The Forest CUMP project, a collaboration between VTT Technical Research Centre of Finland and LUT University, has pioneered methods to convert biogenic carbon dioxide (CO2) emissions from the forest industry into renewable plastic feedstocks. This initiative aims to reduce reliance on fossil fuels in plastic production.

Overview of the Forest CUMP Project

The Forest CUMP project ran for three years and focused on carbon capture and utilisation (CCU) technologies. It aimed to transform biogenic CO2 and green hydrogen into raw materials for plastics, specifically polypropylene and polyethylene. These plastics are integral to everyday products but are traditionally derived from fossil fuels.

Technological Innovations

The project explored the low-temperature Fischer-Tropsch process. This method allows for the conversion of captured CO2 into hydrocarbons. It is economically viable and can be integrated into existing petrochemical plants. This adaptation minimises the need for substantial new investments.

CO2 Capture Techniques

The project involved capturing CO2 emissions from flue gases. It increased CO2 concentration from 10-15% to around 95%. Collaborations with partners like CarbonReuse Finland and Ekotuhka Oy were essential in developing effective carbon capture technology.

Production Process

The production process began with CO2 capture and purification. The recovered CO2 was then converted into ethylene and propylene at the VTT Bioruukki Pilot Centre. This demonstrated the feasibility of using local flue gas CO2 for plastic production.

Finland’s Biogenic CO2 Resources

Finland is uniquely positioned with reserves of biogenic CO2, primarily from its forest industry. This resource is abundant and accessible, unlike in many other European regions. The project suggests that leveraging this CO2 can encourage new industrial value chains while decreasing fossil fuel dependency.

Energy Infrastructure

Finland’s well-established energy and hydrogen infrastructure supports the large-scale adoption of renewable energy sources. The country can generate green hydrogen through water electrolysis, making it suitable for scaling up CCU-based plastic production.

Challenges and Opportunities

One major challenge is securing sufficient green hydrogen for production. The research indicates that converting 10 million tonnes of biogenic CO2 into renewable products would require around 60 terawatt-hours (TWh) of renewable electricity. This is nearly 70% of Finland’s annual electricity consumption, but the country has the necessary bio-based CO2 resources available.

Collaboration and Future Outlook

The Forest CUMP project involved collaboration between various business partners and researchers. Borealis, a leader in sustainable polyolefins, contributed to the initiative. The research outcomes provide a framework for industries aiming to transition from fossil-based plastics to renewable alternatives.
