Revisión de estándares internacionales para la producción de plásticos Oxo-Biodegradables
AI summary Read the abstract
This Spanish undergraduate thesis reviewed ASTM international standards for oxo-biodegradable plastic bags, evaluating whether these materials truly degrade without forming microplastics as their manufacturers claim. The review found that existing standards are insufficient to guarantee that oxo-biodegradable plastics do not produce persistent microplastic fragments.
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.

Review of international standards for the production of Oxo-Biodegradable plastics
AI summary Read the abstract
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.
A scoping and critical review of properties, standards, and regulations of oxo-biodegradable plastics
AI summary Read the abstract
This review critically examines the properties, technical standards, and regulations of oxo-biodegradable plastics, which use pro-oxidant additives to promote abiotic fragmentation followed by biological degradation, discussing the development of new metrological tests needed to substantiate biodegradability claims.
The Misleading Truth About Oxo-Biodegradable Plastics: Critical Analysis of Environmental Impacts and Sustainable Alternatives
AI summary Read the abstract
Researchers critically analyzed oxo-biodegradable polymers marketed as sustainable alternatives to high-density polyethylene, finding that their accelerated fragmentation under light, heat, and oxygen does not result in complete biodegradation but instead generates persistent microplastic particles that contaminate the environment.
A Review of Biodegradable Plastics: Chemistry, Applications, Properties, and Future Research Needs
AI summary Read the abstract
This review clarifies definitions and misconceptions around biodegradable plastics, noting that "biodegradable" labeling is often misunderstood by consumers to mean degradation under any conditions. It surveys analytical standards, existing biodegradable polymer types, and how biomass-derived monomers with oxygen-containing functional groups may enable a new generation of high-performance, environmentally beneficial plastics.
Biodegradability standards for carrier bags and plastic films in aquatic environments: a critical review
AI summary Read the abstract
Researchers critically reviewed existing biodegradability standards for carrier bags and plastic films in aquatic environments and found that current testing protocols do not adequately reflect real-world marine or freshwater conditions. The study suggests that labeling plastics as "biodegradable" may be misleading, since degradation rates vary dramatically depending on temperature, oxygen levels, and microbial communities present in natural water bodies.
