Sustainable Plastics Symposium 2021 - Banner 16:9


The Sustainable Plastics Symposium was the great highlight of Carbon4PUR concluding the project and presenting the major outcomes to the public. We have organized the event together with our sister-project CO2EXIDE, funded by the European Comission in the same call.

The Carbon4PUR highlights session has been introduced by an inspiring talk of Covestro's CEO Markus Steilemann, before we dived in to the project's main outcomes.

With 412 registrants from 46 countries and almost 250 active participants we had a tremendously positive engagement. The high interest proves that current efforts towards a circular economy and the investigation of novel pathways utilizing CO / CO2 as a feedstock is bearing fruits.



Carbon4PUR Highlight Session

Please note: The Carbon4PUR Presentations have been all compiled into a single slide set for your convenience. This slide set includes the following presentations:

Carbon4PUR – Industrial waste gases from steel industry for more sustainable polyurethane applications - Liv Adler (Covestro, coordinator)

Carbon4PUR – Building bridges along industries - Eric de Coninck (ArcelorMittal), Mark Saeys (Ghent University), Martin Machat (Covestro), Geert Snellings (Recticel), Poppy Krassa (Megara Resins)

Carbon4PUR - Assessment of environmental impact, economic aspects, acceptance and perception of CO2/CO utilization and policies and regulations - Arturo Castillo (Imperial College London), Sylvain Pichon (Port of Marseille Fos), Jason Collis (TU Berlin), Jeroen Guinee (Leiden University), Lisanne Simons (RWTH Aachen University), Francisco Koch (Southpole)

Initial invitation

The two projects Carbon4PUR and CO2EXIDE invite you to their final joint presentation of R&D results on renewable production routes towards polyurethanes and ethylene oxide derivatives +++ Focusing on CO/CO2 as raw materials for sustainable chemistry +++ A pan-European approach to a global challenge +++ Framed by contributions and statements of the European Commission, experts from science and industry, and board members of the industrial partners +++

State-of-the-art CCU technologies are paving the way to a future industry that is independent of fossil feedstock. New approaches are addressing the challenges and opportunities of turning our linear “throw-away” society into a Circular Economy, in which recycling processes form the basis of a sustainable production.

These are the core elements of the Horizon 2020 projects Carbon4PUR and CO2EXIDE. Our aim is to reuse carbon from CO and CO2 as a raw material for the synthesis of epoxides and polyurethanes. Utilising off-gas from a steel plant or a biogas plant as feedstock, we follow two different conversion paths and target complementary end products on the pathway to alternative plastics production based on carbon recycling.

In our joint symposium “Sustainable Plastics – Joining CCU, Circular Economy and Power-to-X for better Polymers” we will present the projects’ main results, thus showcasing the potential of a comprehensive linkage between EU-funded research.

After having been compelled to postpone the planned joint event in Aachen last year, we now gladly and warmly invite you to participate in our online symposium. Here is what you can expect.

The symposium will start with a keynote of Søren Bøwadt (European Commission) who will outline the current funding policy in the Green Deal and Horizon Europe programmes, thus relating the research topic of the two Horizon 2020 projects to the European future goals. Marta Domper (A.SPIRE) will continue and give a short overview of the Processes4Planet roadmap and Michael Carus (nova institute) will elucidate the Renewable Carbon Strategy that proposes the combined use of biomass, CO2-utilisation and recycling for sustainable production chains. After lunch, Nieves Gonzalez Ramon (SusChem) will present the recently published Sustainable Plastics Strategy.

Framed by statements of their board members, the consortium partners of Carbon4PUR and CO2EXIDE will then give a detailed overview on the central outcomes of their research efforts, also including regulative measures, social acceptance as well as sustainable electricity and feedstock supply as enablers for a future carbon-neutral process industry.

The symposium will end with a panel discussion with Walter Leitner (MPI-CEC / RWTH Aachen University), Maximilian Fleischer (Siemens Energy), Sophie Wilmet (CEFIC), Carmine Marzano (European Commission) and Florian Ausfelder (DECHEMA) about the demands and next steps towards a circular European industry.

Meet Carbon4PUR at the GHGT in Abu Dhabi (UAE) on 5th to 8th October 2020. There, Dr. Katrin and Prof. Martina Ziefle from the Chair of Communication Science and Human-Computer Interaction Center of the RWTH Aachen University will present results from the acceptance study "Carbon to plastic – but is it worth it? Investigating product preferences and acceptance barriers of Carbon Capture and Utilization" performed within Carbon4PUR.

Update: Symposium postponed +++ Further information will follow +++

Due to the current situation and our responsibility to contain the Sars-CoV-2 virus as quickly as possible, we had to decide to postpone our symposium.

The event will not take place in Aachen as planned. We are currently assessing different locations and dates for the new set-up.

We will try to duplicate the initial program as good as possible, depending on the availability of the speakers and panelists. Therefore, have a look at the initial invitation and program below and follow us on Twitter (@Carbon4PUR, @CO2EXIDEproject) and LinkedIn (Carbon4PUR, CO2EXIDEproject) and subscribe to our newsletters (, to stay up to date.

Carbon4PUR and CO2Exide invite you to discuss a potential circular value chain concept for polyurethanes +++ Focusing on CO2 as a raw material for sustainable chemistry +++ Dialogue between civil society, science and politics with industry +++ Covestro board member announced as guest +++

The days when CO2 was just a waste product of industry are long gone. State-of-the-art CCU technology is paving the way to a sustainable, oil-free future. Our aim is to reuse carbon from CO and CO2 as a raw material for sustainable epoxides and polyurethanes. New approaches are dealing with the challenges and opportunities of turning our linear throw-away society into a Circular Economy, in which ultimately all plastics are recycled.

These are the core elements of the Projects CO2Exide, Carbon4PUR and PUReSmart, which have already achieved significant results. The joint symposium "Sustainable Plastics - Joining CCU, Circular Economy and Power-to-X for better Polymers" offers the opportunity for detailed insights into the research projects.

Subsequent roundtable discussions will focus on the necessary regulations, social acceptance and green electricity as preconditions and enablers for carbon-neutral chemistry.

The symposium will end with a panel discussion with experts from industry, science and the European Commission, i.e.:

  • Sucheta Govil, CCO Covestro
  • Søren Bøwadt, European Comission
  • Walter Leitner, Director MPI-CEC and Professor RWTH Aachen University
  • Maximilian Fleischer, Chief Key Expert Siemens Energy and
  • Eric de Coninck, Low Impact Steelmaking Project Manager ArcelorMittal.

Registration is closed for now.
