dc.description.abstract |
This paper focuses on the verification of properties declared by the manufacturer and,
above all, on the confirmation of biodegradability of commercially available polymer
blends of the Envira© series produced by TART. This company provided two types of
compostable polymer blends based on polylactic acid and starch (further specifications
were not available). For this reason, the concerned samples were subjected to infrared
spectroscopy and gas chromatography with a mass spectrometer to determine the
secondary components contained in the material. The main objective of this work was
to map the behaviour and properties of polymer mixtures in an environment rich in
microorganisms, i.e. compost. The extent of degradation was evaluated by comparing
the results of the mechanical attributes of the samples tested, as well as their structural
changes visible in a scanning electron microscope. |
