ABSTRACT
This chapter presented an overview of different renewable sources used as biodegradable polymers, natural and synthetics, examples and their current uses, natural biodegradable polymers such as chitosan and synthetic biodegradable polymers as polylactones, polyhydrides and polycarbonates, is presented giving different general methods of the biodegradation process that could undergo, such as photodegradation, thermal degradation, hidrolytic degradation, oxodegradation. In the case of natural biodegradable polymers, the importance of the microorganics, the degradation times, the fragmentation that occurs, the factors that intervene in the process to carry out a degradation of the polymeric material. Concluding that the use of renewable sources are a viable alternative to be used in different areas, highlighting nanotechnology, medicine, food, among others.
