“…The samples were subjected to thermogravimetric analysis (TGA) in a TGA Q500 thermal analyzer (TA Instruments, New Castle, DE, USA) at a heating rate of 10 °C min −1 from 40 to 800 °C in an environment of air (50 cm 3 min −1 ). Standard procedures were used to calibrate the instrument for weight and temperature [ 38 ].…”

During the production of polymer-grade propylene, different processes are used to purify this compound and ensure that it is of the highest quality. However, some impurities such as acetylene and methyl acetylene are difficult to remove, and some of these impurities may be present in the propylene used to obtain polypropylene, which may have repercussions on the process. This study evaluates the impact of these acetylene and methyl acetylene impurities on the productivity of the polypropylene synthesis process and on the mechanical and thermal properties of the material obtained through the synthesis of eight samples with different concentrations of acetylene and eight samples with different concentrations of acetylene. We discovered that for the first concentrations of both acetylene (2 and 3 ppm) and methyl acetylene (0.03 and 0.1), the MFI, thermal recording, and mechanical properties of the resin were unaffected by the variation of the fluidity index, thermal degradation by TGA, and mechanical properties such as resistance to tension, bending, and impact. However, when the concentration exceeded 14 ppm for methyl acetylene and 12 ppm for acetylene, the resistance of this resin began to decrease linearly. Regarding production, this was affected by the first traces of acetylene and methyl acetylene progressively decreasing.

“…Luo et al, obtained higher biodegradation rates under industrial composting conditions of (Poly-lactic) acid films when incorporating TiO 2 NP [ 65 ], suggesting that this behavior could be related to hydrolytic degradation, since TiO 2 NP may accelerate some hydrolytic reactions. Similarly, Del Campo et al observed that the incorporation of ZnO in a biodegradable commercial polymer (Ecovio) significantly accelerates the disintegration process under a composting environment [ 66 , 67 , 68 ], indicating that the nanoparticles could initiate or advance some hydrolytic reactions. It was expected that the incorporation of TiO 2 NP delayed the starch film biodegradation since it is well-known that these nanoparticles provide antimicrobial activity to polymeric nanocomposites [ 69 , 70 ].…”

Effect of TiO2 Nanoparticles and Extrusion Process on the Physicochemical Properties of Biodegradable and Active Cassava Starch Nanocomposites

et al. 2023

Biodegradable polymers have been strongly recognized as an alternative to replace traditional petrochemical plastics, which have become a global problem due to their long persistence in the environment. In this work, the effect of the addition of titanium dioxide nanoparticles (TiO2NP) on the morphology, physicochemical properties and biodegradation under industrial composting conditions of cassava starch-based nanocomposites obtained by extrusion at different screw speeds (80 and 120 rpm) were investigated. Films performed at 120 rpm (S120 and S120-TiO2NP) showed completely processed starch and homogeneously distributed nanoparticles, leading to much more flexible nanocomposites than those obtained at 80 rpm. The incorporation of TiO2NP led to an increase in storage modulus of all films and, in the case of S120-TiO2NP, to higher strain at break values. From the Kohlrausch–Williams–Watts theoretical model (KWW), an increase in the relaxation time of the nanocomposites was observed due to a decrease in the number of polymer chains involved in the relaxation process. Additionally, S120-TiO2NP showed effective protection against UV light, greater hydrophobicity and faster biodegradation in compost, resulting in a promising material for food packaging applications.

“…This rate of degradation can be further enhanced employing fillers exerting catalytic activity, such as ZnO particles. [63] Ruggero et al [64] reported the degradation study of a Mater Bi film [PBAT (70 wt%), starch (20 wt%), unknown additive (10 wt%)] under simulated industrial composting (20 days of thermophilic phase followed by 40 days of maturation). They found that the starch grain in Mater Bi, a natural polysaccharide, degrades first generating cavities, which enhances the degradation of the whole polymer by increasing the surface area.…”

End of Life of Biodegradable Plastics: Composting versus Re/Upcycling

et al. 2021

Nowadays the issues related to the end of life of traditional plastics are very urgent due to the important pollution problems that plastics have caused. Biodegradable plastics can help to try to mitigate these problems, but even bioplastics need much attention to carefully evaluate the different options for plastic waste disposal. In this Minireview, three different end-of-life scenarios (composting, recycling, and upcycling) were evaluated in terms of literature review. As a result, the ability of bioplastics to be biodegraded by composting has been related to physical variables and materials characteristics. Hence, it is possible to deduce that the process is mature enough to be a good way to minimize bioplastic waste and valorize it for the production of a fertilizer. Recycling and upcycling options, which could open up many interesting new scenarios for the production of high-value materials, are less studied. Research in this area can be strongly encouraged.
