“…The direct conversion of residues into cast films has also been investigated. ,− Generally, the residues are treated in aqueous solutions, which may contain acids, additives, or both, such as glycerol. Dispersions of lignocellulosic fibers in an aqueous phase rich in pectin are obtained, providing plasticization and processability of the residue.…”

Daily, vast amounts of waste are produced in the orange juice industry, a large part of which is reused in low-addedvalue products. In this work, orange vesicle fiber residues from the juice sieving stage were plasticized by extrusion, producing a thermoplastic citrus pulp (TCP). This pulp was incorporated into poly(butylene succinate) (PBS) at up to 50 wt %. The influence of TCP on the molar mass, morphology, tensile properties, rheological behavior, and biodeterioration of PBS in soil was evaluated. Highly flexible compounds with elongations similar to those of PBS were produced. Scanning electron microscopy analyses suggested good dispersion between the TCP and PBS phases, verified after acid extraction of pectin. Rheological analyses indicated the presence of strong interactions in the interconnected network formed by pectin gel, percolation of TCP lignocellulosic fibers, or both. Analyses of mass loss by burial in soil showed that the higher the TCP content in PBS is, the higher and faster the biodeterioration is. Size exclusion chromatography analyses indicated that the greater the concentration of TCP and the better dispersed it was in the compounds, the lower molar masses populations appeared in PBS, indicating higher rates of degradation of PBS in the presence of TCP. This innovative approach not only reuses the waste produced in the orange juice industry but also demonstrates the potential for obtaining environmentally friendly compounds.

“…The search for new and eco-friendly raw materials for polymers has become the goal of numerous researchers as we have recognized the limitations and damages caused by oil extraction and refining. [1][2][3] Therefore, testing the properties of these eco-friendly polymers has been a major scientific subject in areas such as chemistry, physics, and engineering, with plenty of data available. However, the properties of these new materials after long-term exposure under different conditions are still an area with a scarce amount of data.…”

The objective of this study is to assess, characterize, and forecast the aging effects on the mechanical properties of a vegetable‐based polyurethane foam (PUF) derived from castor oil under elevated relative humidity conditions and at two distinct load orientations (aligned with the expansion direction and perpendicular to it). Ten specimens were subjected to temperatures of 60, 75, and 90°C, along with a relative humidity of 90%, for a duration of up to 60 days. Compression tests, following ASTM D1621‐16 standards and supplemented by 3D digital image correlation, revealed nearly isotropic behavior with marginally lower compression strength in the expansion direction. On the other hand, the strength of the foams at 90°C was higher in that direction. This led to a smaller activation energy (Ea) in this property, which ended up showing a shorter lifespan prediction considering the strength retention in this direction. The stiffness values were proportionally more similar in both directions than the strength ones and this was observed in the Ea for those curves. In contrast to several other foams and polyurethanes, the one examined in this study exhibited consistently higher Ea values for its mechanical properties, particularly in the transverse direction to expansion, surpassing 94 kJ/mol. This indicates a robust diffusion and chemical stability, suggesting its potential for prolonged utilization compared to conventional oil‐based foams. A prediction was made that this foam would lose 50% of its stiffness and strength in around 9.8 and 9.5 years at 20°C, respectively, considering the directions more sensitive to the aging process. This research offers valuable insights for predicting lifespan based on operating temperatures and property retention needs, contributing to the advancement of sustainable materials in structural applications.Highlights Fifty specimens investigated for each of two directions. Evaluation of vegetable‐based PUF aging process unveils density changes. Unique behavior noted: different Ea values for each direction. High Ea values indicate enhanced mechanical stability over oil‐based foams. Lifespan prediction enhances material application prospects.
