Abstract

1.Bioplastics

This lecture deals with basics of bioplastics and their recent advances. Bioplastics consist of biodegradable plastics and biomass plastics. Biodegradable plastics are decomposed by the action of living organisms into water and carbon dioxide. Use of bioresources as starting substrate of polymeric materials reduces greenhouse warming and contributes to global sustainability without depletion of scarce fossil resources. In this class, concept, typical examples, and commercial products of bioplastics are mentioned.

2.Cellulose

Cellulose is the most abundant organic compound on earth and has a linear structure of D-glucose repeating unit. It is one of the three major structural components of the primary cell walls of green plants, along with hemi-cellulose and lignin. This class explains fundamental structure and property of cellulose, important industrial products of modified cellulose, and cellulose nanofibers which are recently expected as new functional materials.
