In the last twenty years, plastic pollution has become a matter of great concern due to the massive use of polymers in disposable packaging applications. The most common materials employed in this field are polyolefins and polyethylene terephthalate (PET), synthesized from fossil resources. The final products are characterized by a low cost and good mechanical characteristics, but they result in a positive carbon footprint and require hundreds of years to be biodegraded. Then, many efforts have been made in order to produce large quantities of bio-based and biodegradable polymers that can be employed in the packaging industry. Unfortunately, the most common employed bioplastics, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA) show poor mechanical properties coupled with poor processability.
