Biodegradable polymers in the general waste stream - the issue of recycling with polyethylene packaging materials

摘要

This paper aims to outline the consequences of unintended mixing of polyolefin and biodegradable materials during recycling. The research was done on blends of high density polyethylene (PE-HD) and two commercial biopolymers intended for packaging applications. The mechanical properties, microstructures, water absorptions and DSC results were analyzed. A significant decrease in the blend properties compared to neat polyethylene and biopolymers is a warning against the poor waste management of biodegradable products.
