Bioplastics - Products from Renewable Resources
Slide 2
IntroductionBioplastics are not a uniform polymer group but a family of products with a variety of properties. A generally accepted definition of the term does not exist. However, two different categories can be distinguished:
plastics based on renewable resources
biodegradable plastics, which can be degraded by microorganisms or higher organisms

Slide 3
Motivation for Using Biomass
Fossil resourcesFossil resources as crude oil are not available in unlimited amounts.
The costs of fossil based chemical products are dominated by the crude oil price.
The use of fossil resources contribute to the greenhouse effect.
Biomass Biomass is a renewable resources.
Renewable resources are almost CO2-neutral.
Renewable resources give production and income alternatives for agriculture and forestry.

Slide 4
Prices of crude oil and standard plastics
Prices of standard plastics like PE, PP and PS depend directly on the price of crude oil
Price of technical plastics does not
Rising crude oil prices will increase the prices of standard plastics

Sugar, Corn and Wheat Price
In the last 2 years the corn and wheat prices increased significantly.
The sugar price fluctuated heavily.
The sugar price is subject to other market criteria than the corn and wheat price.

Slide 22
OutlookPresently, bioplastics are available with a wide range of characteristics. Bioplastics have shown their potential in many applications. Many bioplastics can be normally processed with standard equipment. Biodegradability is an important characteristic for many applications but the use of renewable resources is an additional market demand. Prices for bioplastics are still higher than fossil based plastics. However, bioplastics can be competitive due to their special properties. In future the prices for fossil and renewable based material will both rise.Regulative measures and increased environmental awareness have significantly boosted the market for bioplastics. New economic synthesis routes for the production of polymers based on renewable resources are under development.In the field of technical plastics the development of plastics based on renewable resources, which are not biodegradable, shows a high potential for R&D.
