“…The behavior of PLAR-1LCh could be explained by the low amount of chitosan and the poor interaction between PLA and this kind of chitosan. However, the reduced viscosity observed in the other composites of PLA and chitosan has not been fully explained, although Hijazi et al (Hijazi et al, 2019) reported that higher amounts of chitosan nanoparticles could contribute to increase the shear stresses during the extrusion, resulting in further degradation of PLA.…”

Poly(lactic acid) (PLA) is one of the most used biobased and biodegradable polymers. Due to their high stability, some of the newest grades of PLA are only degradable under severe industrial conditions. For these grades, mechanical recycling is a viable end-oflife option, with great environmental advantages. However, the polymer undergoes degradation during its service life and in the melt reprocessing, which leads to a decrease in properties that can compromise the demand for recycled plastic. The goal of this work was to evaluate the usefulness of adding small amounts of two organic fillers, during the recycling process, for improving the properties of the recycled plastic. The two organic fillers, chitosan and silk fibroin nanoparticles, are obtained from renewable resources. The behavior of the recycled plastics depends on the degradation level of the aged polymer and the nature and amount of the organic filler added. The fillers reduce the further degradation during the melt reprocessing of PLA previously subjected to severe hydrolysis, thus increasing the intrinsic viscosity of the recycled plastic. A careful selection of the organic filler added, based on the nature of the aged plastic, lead to recycled plastics with significant improvements in key mechanical, thermal and barrier properties. Thus, the use of organic fillers obtained from renewable resources can be the basis of a cost-effective and environmentally sound way for improving the mechanical recycling of plastics such as PLA.

“…[ 20,137‐139 ] PLA is produced from agricultural resources such as corn. [ 140‐143 ] It is a thermoplastic aliphatic polyester with several promising properties such as highly transparency, the capability to be simply degraded, high in strength, stiffness, biocompatibility, thermo‐plasticity, monomer renewability and good processability.

In recent years, bionanocomposites have received growing attention in science and industry due to their renewability, biodegradability and superior mechanical properties. Nanocellulose is another promising material that use as a reinforcement filler for bionanocomposite materials due to its lightweight, high surface area, high mechanical strength, high aspect ratio and low density. Different nanocellulose loading, sources, surface modification/functionalization and properties of nanocellulose are important in the production of bionanocomposites. In general, nanocellulose reinforced PLA bionanocomposite offers enhancement in tensile strength and elastic modulus. However, only minimal nanocellulose loadings are required for optimal results due to the incompatibility between the hydrophilic nanocellulose and hydrophobic PLA. This paper reviews the sources of nanocellulose and the properties of nanocellulose with a focus on the tensile and morphological properties of PLA bionanocomposites. Applications of nanocellulose in various industries are discussed in this article. This review article provides some important information. First, this study reviewed the application of nanostructured cellulose in biodegradable polymers. There are two types of nanostructured cellulose: nanocrystalline cellulose (NCC) and nanofibrillated cellulose (NFC). Second, the status on articles published on nanocellulose and PLA/nanocellulose over the past 10 years is reported. Third, the authors of this paper implemented a holistic and critical review to provide a comprehensive understanding of the different properties between NCC and NFC, the application of nanocellulose in bionanocomposites, as well as the properties of PLA and PLA bionanocomposites. Moreover, the influence of NCC and NFC on the tensile and morphological properties of bionanocomposites is covered in this article.

“…Chitosan is a bio‐copolymer, which is formed by N‐acetyl‐D‐glucosamine (acetylated unit) and D‐glucosamine (deacetylated unit), bounding by β‐1–4 bonds (Hijazi et al., 2019; Lopatina & Tsarkova, 2019; Mirsadeghi et al., 2019; Neto et al., 2019). This biopolymer is obtained from the deacetylation of chitin presents in the exoskeleton of crustaceans (Chein, Sadiq, & Anal; Piedrahíta Márquez et al., 2019; D. Yu et al., 2018).…”

Chitosan is a biodegradable polymer and could be applied as packaging. To make chitosan more competitive, plasticizers and cross‐linking agents are added in films. The aim of this paper was to obtain and characterize films of chitosan without or with glutaraldehyde (0; 0.99 mg/150 ml) in different concentrations of glycerol (0, 10, 20, and 30%w/w), for improving the properties like tensile resistance and the water vapor permeability. The films were homogeneous, without phase separation, and with a similar chemical structure. The glutaraldehyde makes the chitosan partly hydrophobic, leading to glycerol saturation in samples with glutaraldehyde and 20 or 30% of glycerol. The Principal Component Analysis for the film with glutaraldehyde and 10% of glycerol presented 3.60 g.mm/kPa.day.m2 of water vapor permeability and 36.96 MPa of tensile resistance. The use of plasticizer and cross‐linking in combination is promising to make chitosan film more competitive on the market of packaging. Practical Applications The addition of glutaraldehyde and glycerol was efficient to improve film properties like water vapor permeability and mechanical properties. The chitosan films with glycerol and glutaraldehyde exhibited similar physical and chemical properties to non‐biodegradable polymers from the petrochemical origin and non‐renewable sources. Furthermore, chitosan films with these additives can be applied as packaging, improving the competitiveness of this biopolymer to the market. The technology described in the paper is important for application as secondary or tertiary packaging in the food industry.
