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?
