“…Hussin et al found that the solid content of the resins increased with increasing organosolv lignin (from oil palm fronds) substitution (from 37% for a "control" PG resin with no lignin up to 54% for 50 wt % of lignin). 144 The same trend was observed for the viscosity; however, a drastic increase in viscosity was reported for 50 wt % organosolv lignin (from 60 mPa.s up to 1000 mPa.s for, respectively, 30 and 50 wt % of lignin). The gel time is the time needed for a resin to gel and correlates thus directly with the amount of cross-linking and end properties like viscosity and molecular weight.…”

“…142,148 For LPG resins, glyoxal is also added in a dropwise fashion to the reaction mixture which is preheated at 80−100°C followed by resinification under reflux conditions for a certain time. 21,22,24,144 In some studies, the staged addition of catalyst (NaOH) is also described during synthesis of LPG resins. 145,146 During production of resoles, both formaldehyde and glyoxal can react via Cannizzaro and form, respectively, formic and glycolic acids ( Figure 5B).…”

“…Hussin et al reported identical absorption bands for PG and LPG resins with organosolv soda and Kraft lignin. 24,144 Both Aziz et al and Hussin et al reported 1 H and 13 C NMR spectra to investigate the structure of (L)PG resins; however, not all peaks were assigned. An in-depth structural characterization is needed to verify the existence of the main structural elements in LPG resins, via a combination of different NMR analyses including 31 P NMR and 2D NMR techniques.…”

“…For a reaction time of 2 h, the gel time decreased with increasing lignin content; the rate of polycondensation and cross-linking was the highest in 50 wt % organosolv LPG resins. 144 Furthermore, Hussin et al demonstrated that the bonding strength of the LPG resins increased with increasing lignin content. An increased bonding strength could also increase the wood panel strength which is beneficial in the wood panel industry.…”

The utilization of lignin and glyoxal as potentially sustainable and less hazardous building blocks for phenolic resins is an emerging research field. Lignin thereby serves as a partial, macromolecular substitute for phenol, while glyoxal fulfills the role of an aldehyde cross-linker. In the first part of this perspective, the industrial context of lignin and glyoxal will be expounded with a focus on their origin and production processes. In the framework of phenolic resins, the use of lignin and glyoxal can be categorized into two research domains: (i) glyoxalation to improve the reactivity of lignin prior to resin synthesis and (ii) direct resin synthesis using lignin and glyoxal with glyoxal immediately serving as the cross-linker. This perspective provides a comprehensive overview of the progress made in both domains, pinpointing the opportunities, blind spots, and challenges that lay ahead.

Environmental impact assessment is a crucial aspect of biofuels production to ensure that the process generates emissions within the designated limits. In typical cellulosic biofuel production process, the pretreatment and downstream processing stages were reported to require a high amount of chemicals and energy, thus generating high emissions. Cellulosic butanol production while using low moisture anhydrous ammonia (LMAA) pretreatment was expected to have a low chemical, water, and energy footprint, especially when the process was combined with more efficient downstream processing technologies. In this study, the quantification of environmental impact potentials from cellulosic butanol production plants was conducted with modeled different pretreatment and product separation approaches. The results have shown that LMAA pretreatment possessed a potential for commercialization by having low energy requirements when compared to the other modeled pretreatments. With high safety measures that reduce the possibility of anhydrous ammonia leaking to the air, LMAA pretreatment resulted in GWP of 5.72 kg CO 2 eq./L butanol, ecotoxicity potential of 2.84 × 10 −6 CTU eco/L butanol, and eutrophication potential of 0.011 kg N eq./L butanol. The lowest energy requirement in biobutanol production (19.43 MJ/L), as well as better life-cycle energy metrics performances (NEV of 24.69 MJ/L and NER of 2.27) and environmental impacts potentials (GWP of 3.92 kg N eq./L butanol and ecotoxicity potential of 2.14 × 10 −4 CTU eco/L butanol), were recorded when the LMAA pretreatment was combined with the membrane pervaporation process in the product separation stage.
