Introduction
Increased use of biomass resources for manufacturing plastic products can be effective in reducing
global warming and the depletion of fossil resources.
Current plastic products are composed of biobased synthetic polymers, fossil-based synthetic polymers,
natural polymers and additives that can include biobased materials.
Biobased plastics refer to plastics that contain materials wholly or partly of biogenic origin.
