Summary: A new type of foam material was developed by partially substituting non-sustainable phenol with lignin extracted from pine wood residues using a green levulinic acid-based solvent. The novel foams were compared to commercially available lignin-based foams in terms of various features, including foam density, microstructure, surface hydrophilicity, chemical grafting, and mechanical and thermal properties. The research showed that up to 30 wt% of phenol can be replaced without compromising the foam properties, indicating the potential of lignin-based foams as sustainable and renewable alternatives to petrol-based counterparts.

Summary: In this study, biobased novolacs phenol-formaldehyde (BNPF) resins were developed by partially replacing petroleum-derived phenol and formaldehyde with lignin derived from kraft biorefinery and modified kraft biorefinery-derived lignin, respectively. The lignin was chemically modified through the periodate oxidation process, and a series of BNPF resins were synthesized by replacing phenol and formaldehyde with lignin and oxidized lignin. The NPF resins exhibited the formation of methylene linkages in the phenolic rings. The bonding performance tests showed that BNPF resin adhesives have high adhesion strengths (>0.7 MPa). This research provides a promising perspective for utilizing natural polymers such as lignin for the synthesis of biobased wood adhesives.

Summary: Wood modification using phenol-formaldehyde resins is a well-known method to enhance wood properties, but the use of non-renewable phenol has led to research on substitute resources. This study explores the use of lignin-derived organic products as substitutes for phenol in the resins. The results show that up to 30% substitution does not significantly affect wood modification quality, and the amount of formaldehyde added can be reduced.

Summary: Using Kraft lignin, lignin-based phenol-formaldehyde (LPF) resins were synthesized as a potential replacement for petrochemical-based adhesives. The LPF resins showed improved properties compared to the control phenol-formaldehyde resin (PF) in terms of viscosity, gel time, shear strength, and curing behavior. However, the addition of EKL in PF reduced its thermal stability.

Summary: This study aims to produce environmental-friendly phenol-formaldehyde resin by using phenolated lignin and bio-oil extracted from oil palm empty fruit bunch black liquor to substitute phenol. The modified resins were prepared by heating a mixture of phenol-phenol substitute with NaOH and formaldehyde solution, and the physical properties of the resins were tested. Results showed that the substitution of 5% phenolated lignin improved the properties of phenol-formaldehyde resin. The production process of phenolated lignin-phenol-formaldehyde resin was also environmentally beneficial.

Summary: This study used acetone fractionation to increase the homogeneity of softwood kraft lignin and develop new products. The acetone soluble and insoluble fractions were analyzed for their elemental composition, chemical structure, and thermal properties. The acetone soluble fraction showed an increase of 24% in phenolic hydroxyl content. It was used to replace phenol in phenolic resin, resulting in a higher adhesion strength. The acetone insoluble fraction, on the other hand, was used to replace petroleum-based polyol in polyurethane resin, with the help of a bio-derived solvent. Tailoring the structure of kraft lignin through solvent fractionation allowed for the replacement of two major petrochemicals in resin formulations, which would otherwise be challenging due to the heterogeneity of softwood kraft lignin.

Summary: Liquefaction products obtained from bagasse lignin and phenol with sulfuric acid as catalyst were used to synthesize bagasse lignin-based phenol formaldehyde (BLPF) resin. The BLPF resin showed a dark brown appearance, lower solid content, swelling degree, pH, and storage life compared to traditional PF resin. Although the bonding properties of the resin were undermined, the environmental performance was enhanced. The BLPF resin-based plywood had lower bonding strength, reduced formaldehyde emission, and increased weight loss compared to plywood made with PF resin.

Summary: Superabsorbent polymers (SAPs) have high water absorbability and are widely used in agriculture. However, bio-based SAPs, which are environmentally friendly, have drawbacks such as time-consuming synthesis and low absorption capacity. In this study, a novel cellulose-based SAP was developed through modified cellulose, which exhibited superior absorbency, thermal stability, pH stability, and biodegradability compared to commercial fossil-based SAPs. This indicates that Cellulo-SAP can be an effective alternative in agriculture.

Summary: This study investigated the improvement of glucose isomerase production and cell growth using synthetic bacterial consortia on pretreated wheat straw as the sole carbon source. Thirteen cocultures were constructed based on monocultures from six cellulolytic soil bacteria. Only five cocultures exhibited cell growth and enzyme production synergies, with the highest synergism degree found in coculture J composed of Mycobacterium sp. MKAL3 and Stenotrophomonas sp. MKAL4. This synergism was unique to growth on wheat straw and could rely on specific compounds released by the MKAL3 strain.

Summary: The key to solving the ecological hazards caused by semi-dry sintering flue gas desulfurization ash lies in the realization of low-temperature and high-efficiency oxidation of CaSO3. Subcritical hydrothermal technology was used to oxidize CaSO3, achieving an oxidation rate of 89.83% at 180 degrees C, 2 MPa for 120 min with a solid-to-liquid ratio of 1:20. The macroscopic oxidation kinetics of CaSO3 in the subcritical hydrothermal reaction system were investigated, and a mathematical model incorporating various factors was established. The subcritical hydrothermal technology not only improves efficiency but also enables the one-step preparation of CaSO4 whiskers, facilitating cost-effective and high-value resource utilization of semi-dry FGD ash.

Summary: The study investigated the performance of different carbon-supported CoMoP and CoMoW catalysts in catalytic hydrodeoxygenation (HDO) of pyrolysis oil using formic acid as an in-situ hydrogen source in supercritical ethanol. Among them, the CoMoP catalyst supported on ASC-Zn and the CoMoW catalyst supported on MWNTs showed the best HDO performance, achieving higher oil yield, lower oxygen contents, and higher degree of deoxygenation (DOD) at both 300℃ and 350℃ for 2 hours. However, stability tests revealed slight deactivation of both catalysts, possibly due to leaching of active metals or coke/carbon deposition on active sites.

Summary: Ni-ReOx bimetallic catalysts (Ni-ReOx/TiO2) were prepared and showed high activity in the hydrogenation of furfural (FAL) to tetrahydrofurfuryl alcohol (THFOL) under mild reaction conditions. The catalyst exhibited significantly higher initial reaction rate and THFOL formation rate compared to Ni/TiO2, due to the rich Lewis acidic ReOx and the electron interaction between ReOx and Ni nanoparticles. The ReOx decoration of the catalyst decreased the activation barrier of -C=O hydrogenation and favored hydrogen spillover and C=O bond activation on Ni, leading to a synergistic effect of Ni and ReOx. The catalyst also demonstrated stability and potential for industrial application.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
