Abstract Bio‐oil formaldehyde resole (BFR) can be used as adhesive in plywood industry. However, the BFR has a lower thermal stability, and reason is still unclear. Herein, reactivities of four representative phenolic compounds bio‐oil, including two ortho phenols (2‐methylphenol, 2‐methoxyphenol) para (4‐methylphenol 4‐methoxyphenol), well stabilities prepared resoles are investigated. The results show that reactivity an phenol higher than phenol. from stability decomposes even when heated at low temperature 100 °C. methylphenol generally methoxyphenol. Based on results, for bio‐oil speculated.

Hydrogen is a well-known clean energy carrier with high energetic yield. Its versatility allows it to be produced in diverse ways, including biologically. Specifically, dark fermentation takes advantage of organic wastes, such as agro-industrial residues, obtain hydrogen. One these harmful wastes that poorly discharged into streams sugarcane bagasse pentose liquor (SBPL). The present study aimed investigate hydrogen generation from SBPL batch reactors by applying different food/microorganism (2–10 F/M) and carbon/nitrogen (10–200 C/N) ratios under mesophilic thermophilic conditions. Biohydrogen was all experiments along other soluble microbial products (SMPs): volatile fatty acids (VFAs) (at least 1.38 g L−1 1.84 the average C/N F/M conditions, respectively) alcohols 0.67 0.325 respectively). Thermophilic (t-PLRs) showed highest H2 production (H2 maximum: 1.9 ± 0.06 L 100 yield (HY) (1.9 0.54 moles substrate−1 2 when compared ones (m-PLRs). main VFA acetate (>0.85 L−1, considering both nutritional conditions), especially through butyrate pathway, which most common metabolic route experimental essays. Considering level acid dilution used pretreatment (H2SO4 (1%), 1.1 atm, 120 °C, 60 min), unlikely toxic compounds furan derivatives, phenol-like substances (neither measured), (<1.0 L−1) hinder (PLRs). Sugarcane may become suitable gateway convert highly polluting waste renewable feedstock valuable production.

Abstract The substitution of low-carbon and carbon-negative materials is an important pathway a fundamental means reducing carbon emissions in the construction sector. This work utilized pulping wastewater (black liquor (BL)) produced from rice straw alkaline-oxygen cooking to synthesize green concrete silica-lignin (SL) admixture through acid regulation. novel was employed replace conventional high-carbon alkali powder, its integration with recycled aggregates significantly enhanced performance sprayed concrete. results show that addition increased slump compressive strength by 46.3% 28.5%, respectively, while rebound ratio 67.3%. Moreover, use effectively reduces global warming potential (GWP) production. When rate reaches 50%, are reduced 44.7%, only 183 kgCO 2 eq/m 3 . added not exhibited but also contributed reduction CO emissions, decreased amount used building structures, achieved goal reduction. provides valuable insights for advancing sustainable practices industry.
