Decarbonising plastics – On the technologies and framings of carbon capture and utilisation
Palm, Ellen LU
(2024)
- Abstract
- Plastics consist of fossil fuels, from both a feedstock and energy perspective and thus need to decarbonise. This thesis maps and explores the framings and technologies that surround plastics decarbonisation and the potential mitigation pathway of carbon capture and utilisation. Here, three of the main findings are presented.
By unpacking how EU policymakers understand issues concerning plastics, this thesis exposes how they are mainly conceptualised as a waste issue. This narrow framing of the issues concerning plastics neglects their complexities and systemic nature. The explicit downplaying of climate impact is especially noteworthy. If policymakers do not recognise the connection between plastics and climate change, it is not...

This thesis maps and explores the framings and technologies that surround plastics decarbonisation and the potential mitigation pathway of carbon capture and utilisation. Here, three of the main findings are presented.
By unpacking how EU policymakers understand issues concerning plastics, this thesis exposes how they are mainly conceptualised as a waste issue. This narrow framing of the issues concerning plastics neglects their complexities and systemic nature. The explicit downplaying of climate impact is especially noteworthy. If policymakers do not recognise the connection between plastics and climate change, it is not likely that they will introduce policy measures to address it.
In a first-of-a-kind study, this thesis shows that, from a technological perspective, European plastics production could decarbonise via the pathway of carbon capture and utilisation. However, producing plastics from water and carbon dioxide is extremely energy-intensive and hence very costly. Even if this perspective neglects all the social, political and institutional considerations, it serves as a thought experiment that plastics production could decarbonise.
How expectations of carbon capture and utilisation, and the larger imaginary of circular carbon, are articulated can shape and limit how and whether they are enacted. This thesis maps and analyses such framings in two cases: firstly, within the scientific carbon capture and utilisation community, and secondly within the plastics and petrochemical industry. The material shows that the scale of production (growth) is not discussed, and strategies to decarbonise via low-tech pathways are often neglected.
If supporting the technological development surrounding plastics decarbonisation, all these aspects must be recognised. Failure to do so risks resulting in delayed decarbonisation efforts. In conclusion, this thesis advocates for a pluralistic approach to plastics decarbonisation and emphasises the importance of considering both high- and low-tech mitigation pathways, since one perspective or technology is insufficient to address the complexities of plastics decarbonisation.
