Review of international standards for the production of Oxo-Biodegradable plastics
Summary
This thesis reviewed ASTM international standards for oxo-biodegradable plastics, examining whether these materials meet biodegradation claims and whether standards adequately address microplastic formation. The analysis found that current standards do not confirm that oxo-biodegradable plastics fully break down without leaving harmful microplastic residues.
The present degree work was developed with the main objective of examining the ASTM international standards that justify the biodegradation of oxo-biodegradable plastics, in this way to theoretically review if the Oxo-Biodegradable LDPE low-density polyethylene plastic bags comply with the results provided. by its manufacturers, who specify that it does not generate microplastic once discarded, thus reducing its accumulation in terrestrial and aquatic ecosystems.
