“…Wennman et al further developed a sustainable binder based on wheat gluten (WG) and a polyelectrolyte complex (PEC) made from chitosan, carboxymethyl cellulose, and citric acid, which can be used with cellulosic fibres, creating a fully bio-based nonwoven product [23]. The potential of environmentally friendly bio-based polyfurfuryl alcohol resin is discussed by Odiyi et al [24]. Chemical modification of lignin to produce bio-based binders has been explored by a number of researchers [25,26].…”

The use of lime as a binder in hemp–lime considerably increases the drying time of hemp–lime after casting. Furthermore, lime is a non-renewable mineral resource. As such, this paper explores the effectiveness of using an alternative non-mineral binder instead of lime to formulate a novel hemp–shive insulation. The moisture-dependent thermal conductivity, adsorption isotherm, vapour diffusion resistance factor, and in-built hygrothermal performance of four variants of a novel bio-based insulation were investigated. The hygrothermal performance of the novel hemp–shive insulation was compared with that of a previously developed novel hemp–lime insulation. No significant variation in thermal conductivity of hemp–shive insulations between the equilibrium moisture contents (EMC) at 0% and 50% relative humidity (RH) was observed, but there was a substantial increase in thermal conductivity hemp–shive insulations when the material reached the EMC at 98% RH. The average dry thermal conductivity values of hemp–shive and hemp–lime insulations were also similar. The adsorption isotherms of hemp–shive insulations were determined at 0%, 20%, 50%, 70%, 90%, and 98% relative humidity steps. At 98% RH, the moisture adsorption capacity of hemp–shive insulations was 4-to-5-times higher than that of hemp–lime insulation. Hemp–shive insulations’ vapour diffusion resistance factor (µ value) was about double the µ value of hemp–lime insulation. Hemp–shive insulations exhibited 4-to-5-times higher water absorption resistance than that of hemp–lime insulation. Numerically determined porosity values of hemp–shive agree with the values of wood-based insulation materials of similar density. Finally, using all experimentally acquired data as inputs, dynamic whole-building hygrothermal simulations were carried out and the results show that novel hemp–shive insulation materials perform at a similar level to the hemp–lime insulation in terms of heating and cooling energy demand but require 45% less energy for humidification. However, the relative humidity inside the hemp–shive wall remains higher than 70%, which can potentially induce mould growth.

“…FA and its derivatives possess a range of functionality and attractiveness in different application areas . In particular, a large number of FAs have been employed as biobased monomer systems in the synthesis of furan resins over the years. − These resins are widely applied in the foundry industry as adhesives, mortars, grouts, impregnants, and sealants for mold structures in the metal casting industry . A critical assessment of prevailing controversies and counterarguments provides a brief view of various aspects of FA polymerization chemistry .…”

Developing sustainable plastics, for instance, green poly(ethylene 2,5furandicarboxylate) (PEF), is a promising pathway to decrease the reliance on petroleumbased plastics and the pollution of the environment. However, the preparation of highperformance PEF materials that integrate superior barrier and mechanical properties remains a huge challenge. In this study, a BNNSs/PEF composite film with excellent mechanical and barrier performance was fabricated by using furfuryl alcohol simultaneously acting as a high-level dispersant and interfacial reinforcement matrix for BNNSs. The optimized BNNS/PEF composite film with 0.2 wt % BNNSs (BP2) shows a compacted aligned structure and excellent comprehensive performance with 79.2 MPa tensile strength (43% enhancement), 4.2 GPa Young's modulus (83% enhancement), high gas barrier, and enhanced thermal stability. Remarkably, fruit testing conditions (e.g., relative humidity of 90−95%, temperature of 30, and natural light) showed that the BP2 composite film extended the shelf life of fresh strawberries by at least at least 5 days in an ambient environment. The overall performance of the BP2 composite film is optimized to be superior, which opens up an avenue for practical applications in the field of packaging materials.

This paper presents a comparative assessment of hygrothermal effects on the mechanical and thermomechanical properties of resin‐infused thermoplastic E‐glass fiber‐reinforced composites (FRC) in the marine environment. The thermoplastic FRCs were immersed in seawater at two different aging temperatures, that is, 35 and 70°C. The quasi‐static tests were conducted on unaged and aged FRCs, followed by scanning electron microscopy (SEM) to determine the effect of the marine environment on the mechanical properties and damage progression. The specimens immersed at 70°C showed a significant drop of 46.7%, 39.7%, 22.6%, and 16% in mechanical properties (tensile, compression, flexural, and ILSS) mainly due to plasticization, matrix cracking, and fiber/matrix debonding. The specimens immersed at 35°C showed a reduction in tensile, compressive, and flexural strength of 10%, 14.7% and 1.9% respectively, with no significant effect on ILSS. In addition, dynamic mechanical analysis (DMA) reveals that prolonged aging induces an increase in glass transition temperature due to polymerization reactions. This work is intended to reveal the effect of extreme marine environment on the resin‐infused thermoplastic FRC and to provide a useful reference for their potential structural applications in the marine industry.Highlights Influence of aging conditions on the long‐term performance of FRCs. Hygrothermal aging leads to an increase in the glass transition temperature. The marine environment degrades mechanical properties of FRCs by up to 50%. Matrix cracking and fiber‐matrix debonding evolved as dominant failure modes.
