Aqueous Dissolution and Recovery of Poly(Vinyl Alcohol) in Multilayer Film. [PDF]

ChemSusChem
Schematic of a water‐based recycling process for PVOH/PBAT‐PLA tri‐layer films, showing selective PVOH dissolution, process condition screening, and recovery of both polymer fractions. In this work, solvent‐based recycling was applied to a multilayer film of PBAT‐PLA and PVOH, where the dissolution conditions were optimized and the reusability of the ...

Study of the compatibilizer effect in the properties of starch/polyester blends [PDF]

Polímeros, 2013
The mechanical, viscoelastic and structural properties of starch/ poly (butylene adipate co-terephthalate) (PBAT) blown films produced by reactive extrusion were evaluated using citric acid (CA) and maleic anhydride (MA) as compatibilizers.

Photodegradation of biobased polymer blends in seawater: A major source of microplastics in the marine environment

Frontiers in Marine Science, 2022
IntroductionBiobased polymer blends have been recommended as an eco-friendly solution to abate plastic pollution in the environment. However, the formation of microplastics (MPs) by photodegradation of biobased polymer blends in the marine environment is

Biodegradable starch-based films containing saturated fatty acids: thermal, infrared and raman spectroscopic characterization

Polímeros, 2012
Biodegradable films of thermoplastic starch and poly (butylene adipate co-terephthalate) (PBAT) containing fatty acids were characterized thermally and with infrared and Raman spectroscopies. The symmetrical character of the benzene ring in PBAT provided

Using in vitro bioassays to guide the development of safer bio-based polymers for use in food packaging

Frontiers in Toxicology, 2022
Petroleum-based polymers traditionally used for plastic packaging production have been shown to leach dangerous chemicals such as bisphenol-A (BPA). Bio-based polymers are potentially safer alternatives, and many can be sustainably sourced from waste ...

Fungal degradation of reprocessed PP/PBAT/thermoplastic starch blends

Journal of Materials Research and Technology, 2020
It is well known that the inadequate disposal of polymeric materials causes significant environmental problems. Recycling and the use of biodegradable polymers are among the methods used to minimize these problems. However, the low mechanical performance
