8th Circular and Biobased Performance Materials Symposium 2019

The 8th Circular and Biobased Performance Symposium was held in Wageningen, the Netherlands, on Wednesday 19 June 2019. Key industry players from the entire value chain, ranging from waste, agrifood to polymer processing companies, end application producers and users, reflected on their R&D strategies.

In this edition, special attention was given to the use of performance materials from biobased residual side streams and post-consumer waste.

In the opening session, the symposium chairmen Jan Noordegraaf and CBPM director Christiaan Bolck shared their view on the market developments and the research agenda for Circular and/or Biobased performance materials.

From industry, companies like Cosun, Sabic, Covestro and Total Corbion PLA reflected on the development and creation of new circular and biobased polymers. From a user perspective, toy manufacturer BiOBUDDi informed the audience about the (technical) challenges they encounter in product development.

From the waste to material perspective, waste processor Renewi, the Dutch organisation responsible for recycling of post-consumer packaging (Nedvang), and Wageningen FBR showed challenges and accomplishments they have made in converting post-consumer waste into new materials and products.

  • The Circular and Biobased Performance Symposium of the Wageningen University … is maybe the fine line in the sand that makes the Netherlands one of the leading countries of the EU when it comes to the bio-based industry. Does the Nordic countries have this? Does Belgium or France have this? I’m not sure.
  • The Circular and Bio-based Performance Symposium of the Wageningen University is the cherry on the cakes that makes the Netherlands shine a bit more.
