As well as plastics and bioplastics, the other types of biopolymer were given more opportunities and many of them were commercialized. Biopolymers have unique properties (there are some exceptions); they are produced and degraded through the biological system, therefore they are non-toxic (mostly); they are bioavailable (mostly); They are diverse, applicable, and renewable. There are many types of classifications which are based on their chemical, biological and physical properties; their source (plant, animal and microbes); their applications (medicinal, pharmaceutical, agriculture, industrial); their economic value; their biodegradability (biodegradable, non-degradable); their bioavailability; their cost and their mechanical properties. In this chapter, the classification which is based on the polymer chemical structure will be used. The main limiting factor in commercializing biopolymers is their production cost. For that this chapter will use the classification which is based on the polymer chemical structure [35].
