Photo–degradable and recyclable starch/Fe3O4/TiO2 nanocomposites: feasibility of an approach to reduce the recycling labor cost in plastic waste management
AI summary Read the abstract
Researchers developed biodegradable starch/Fe3O4/TiO2 nanocomposite films and found that increasing the iron-titanium nanoparticle content improved hydrophobicity and photodegradability under UV-A light, while also conferring magnetic properties that could allow the film to be recovered and recycled — reducing labor costs in plastic waste management.
In this research, a biodegradable starch/FeO/TiO bio-nanocomposites (SFT) were produced using different nano FeO/TiO (FT) (3, 5, and 10 (wt% dry based)) contents. Mechanical properties, visual properties, moisture-sensitive parameters, magnetic properties, and physical properties of the film specimens were investigated. Photodegradability of film specimens was also evaluated under UV-A irradiation. The FT content increased the hydrophobicity of the film specimens. Tensile strength (TS) of SFT films was increased by increasing FT up to 3%. Elongation at break (EB) and tensile energy to break (TEB) were decreased by adding FT content up to 3% simultaneously. The film specimens' water vapor permeability (WVP) was decreased with increasing FT content. The intrinsic viscosity of SFT was decreased by increasing FT content. It confirms the enhancement of photodegradability of the specimens by increasing FT content. It seems the compatibility of FT with biopolymer has had great effects on these properties. Use of FT-based nanocomposites is an appropriate approach to developing magnetic-recyclable and photodegradable packaging materials.

Biodegradable nanocomposite films containing combined ZnO and TiO₂ nanoparticles in PBAT: A strategy to mitigate microplastic persistence from food packaging
AI summary Read the abstract
This study created new biodegradable food packaging films by combining a plant-based polyester (PBAT) with zinc oxide and titanium dioxide nanoparticles, finding that the combination accelerated the material's degradation while also improving its mechanical and safety properties. The goal was to develop packaging that breaks down faster in the environment, producing fewer persistent microplastics compared to conventional plastics. Results suggest certain nanoparticle concentrations produce materials that are both commercially viable for packaging and meaningfully less likely to accumulate in ecosystems.
