However, plastics and bioplastics cover an abundance of types, each with its own individual profile, so they present an enormous diversity which makes them so successful in numerous applications. It was shown that polyolefins present the same oxo-biodegradability of biopolymers, but they are more economical and effecting during use, so certain they will remain the materials of choice for packaging application. Bio-based polymers have already found important applications in medicine field, where cost is much less important than function. It seems very unlikely that biodegradable oil based polymers
