Synonyms Biobased materials Definition Biobased polymers are sustainable polymers synthesized from renewable resources such as biomass instead of the conventional fossil resources such as petroleum oil and natural gas, preferably based on biological and biochemical processes. They are characterized by the nature of carbon neutral or carbon offset in which the atmospheric CO 2 concentration does not increase even after their incineration. Introduction The subject of "sustainable polymeric materials" has already constituted one of the most important fields in the modern science and technology, even though the concept emerged only in the beginning of this century. The use of sustainable polymeric materials is believed to contribute to the preservation of natural resources and protection of the global environment because of its "carbon offset" or "carbon neutral" nature and ought to be essential for attaining better human life in this century. In particular, the development of renewable polymeri ...
