“…There are some excellent works on PLA modification and processing. For example, Kühnert et al [42] reviewed the state-of-the-art and new developments concerning PLA processing; Tripathi et al [45] discussed PLA blends and composites for durable applications; Parameswaranpillai et al [46] reviewed, specifically, the use of cellulose and nanocellulose in PLA composites; Zhao et al [47] reviewed strategies to improve the toughness of PLA, aiming at overcoming its inherent brittleness and relatively poor impact strength.…”

Environmental and social impacts caused by petrochemical plastics are generating significant concerns on a global scale. Bioplastics can contribute to the transition to more sustainable materials, but they did not expand at the expected rates in the early 2000s. With recent predictions indicating that the bioplastic capacities will almost triple in the next five years, what are the conditions that may now be combined to justify and enable such an expansion? This paper uses the case of PLA and general insights into other bioplastics (stylized facts) to detail these conditions. The results show that many bioplastics remained unused during the 20th Century, with interest increasing when plastic pollution became flagrant in the 1980s. For PLA, many efforts have been made to solve the technical and market issues, including through intense cooperation among stakeholders. While environmental concerns have propelled bioplastics, the general absence of structured end-of-life alternatives (e.g., recycling and composting infrastructures) hinders their diffusion. Conversely, the expanding regulations related to plastic pollution are now the primary driver of the growth of bioplastics. Therefore, for bioplastics, and especially PLA, the conditions seem to be emerging for them to diffuse at the predicted rates, but structural limitations in the bioplastics value chain still compromise the large-scale substitution of petrochemicals. This trend indicates that establishing end-of-life alternatives for bioplastics could help to remove the bottleneck in their diffusion process.

Chitosan-Coated Packaging Papers—Strength and Thermal Stability

et al. 2023

The aging of paper depends on various factors, including environmental conditions, microbiological factors and chemical composition. Chitosan-coated paper is an eco-friendly material that has potential use in various packaging applications due to its mechanical, barrier and antibacterial properties. In this study, the aging stability of chitosan-coated wood-free wrapping paper was evaluated by examining pulp and four paper samples with different quantities of chitosan. Accelerated thermal aging and dynamic thermogravimetric analysis were used to assess the aging stability, while color changes were examined to understand the impact of chitosan coating. The study found that increasing chitosan coating led to improved aging stability due to the improved crosslinking process between chitosan and paper. The coated paper samples displayed a yellowish hue after 72 h of aging, with increased strength and resistance to weight loss. TGA results indicated that the temperature of complete burning of the sample increased with increasing chitosan coating. Additionally, coated paper samples exhibited a more even surface and improved barrier properties. Overall, chitosan-coated paper is a promising material for sustainable and eco-friendly packaging, printing and wrapping applications. This study’s findings have important implications for the development of environmentally-friendly packaging materials that possess desirable mechanical and barrier properties.
