Insights into related circular economy challenges and examples.
Inhaltliche Voraussetzungen (erwartete Kenntnisse)

General polysaccharide chemistry, cellulose chemistry
Lehrziel

The students can name the crucial properties of cellulose nanofibers, bioplastics and derived composites. They can derive general principles from an example that is presented during the lecture. They know about the relation between the molecular structure and properties of the biopolymers. The students know the possibilities and limitations of the industrial application of biopolymers and circular economy.
