Materials: From fossil based to bio-based

Ulrica Edlund Professor Fiber- and Polymer Technology KTH, Royal Institute of Technology

The advanced polymer material age

The age of growing global awareness :

Need for sustainability!

1. Do we need this product?

2. Material source?

3. Material health?

4. Material reutilization?
