This will be followed by a presentation from Mark Spekreijse about the focus and objectives of the Circular Plastics NL program, which is the main framework for engaging in new projects.

The conference will conclude with a panel discussion, moderated by Rosa Scholtens, focusing on the next steps that should be taken in the transition to circular plastics. The panel will discuss where we should focus our efforts and how we should proceed, considering both technological and non-technological aspects. The conversation will be used as conclusion to update our Circular Plastics Roadmap and contribute to steering the transition towards circular plastics effectively and sustainably.
