Abstract

The biodegradable plastics were introduced in the 1980s in order to detect possible renewable feedstock to produce non petroleum-based plastics, as well as to reduce the environmental burdens due to the landfill volume increase To this end, in the la I years different typologies of bioplastics like PHB, PCL, Mater-Br and PLA were introduced In order to verify the benefits of bioplastics in comparison to conventional plastics it is necessary to evaluate the environmental impact derived from production, utilization and disposal of the two kinds of material Nowadays, the most important tool to evaluate the environmental impact of a material (for example bio or conventional plastics) is the life cycle assessment (LCA) that determines the overall impact of a plastic on the environment by defining and analysing several impact indices In particular, global warming, human toxicity, abiotic depletion, eutrophication, acidification and many other impact indices directly related to the production, utilization and disposal of the plastics studied in this work, re considered In this paper an analysis of the different disposal scenarios (in particular composting and recycling processes) applied to the most important bioplastics currently on the market (PLA made from Nature Works and Mater-Br made from Novamont), was carried out by using the LCA methodology and by also taking into account the Land Use Change (LUC) emissions Cost and benefits of the bioplastic disposal were also compared to these of the conventional plastics
