Based on 6 403 research articles in the Web of Science database from 2000 to 2023, information visualization technology is employed to analyze the literature year distribution, keyword co-occurrence and research hot spots, author cooperation network, institutional and national cooperation network, published journals, and co-cited literature in the middle of hydrothermal pretreatment. Our results show that the number of applied research publications related to hydrothermal pretreatment has increased every year in the past two decades. Among these publications, China (36.5%) is the most active country in the world, followed by the United States (14.6%) and Japan (8.2%), with increasing global cooperation. The Chinese Academy of Sciences ranks first among the institutions in the light of total publication output (245 articles, accounting for 3.82%). Among 955 journals, Bioresource Technology is cited the most frequently. The study is centered on the enhancement and potential evolution of lignocellulosic biomass raw materials via hydrothermal pretreatment for subsequent bioenergy transformation. Concurrently, the domain of hydrothermal pretreatment has progressively become more cross-disciplinary, intertwining with the sectors of microbial populations and genomes.

The rapid advancement of biomedical polymers has raised significant concerns about the disposal of medical polymer waste. Sustainable biomass materials derived from renewable sources in nature have emerged as promising alternatives to petroleum-based polymers for medical applications and tissue engineering due to their abundance, biodegradability, and environmental friendliness. In tissue engineering, interconnected macropores within biomaterials are crucial as they provide space and interfaces for cells, enhancing permeability for nutrient and waste transport. In this review, we summarize recent developments in the use of biomass materials to engineer macroporous tissue engineering scaffolds. We highlight key techniques, such as microparticles assembly, leaching template, and bioprinting that can create macropores within scaffolds composed of biomass materials and their composites. In addition, we investigate the applications of the macroporous scaffolds in wound healing, with a focus on cell behaviors within macroporous constructs and their role in treating chronic wounds. We envision that the combination of the bicontinuous macropores and biomass-based materials can create an ideal cellular environment and provide a powerful platform for wound healing and tissue regeneration.

Lignin is a natural resource used for energy production and a widely applied basis in the chemical industry. Physiological and wood anatomical evidence now suggests that the degree of lignin deposition in plant cell walls is constrained by low temperature and enhanced by increased temperature. Placing these findings in an industrial setting implies planning lignin supply in the forecasted global warming scenario.

A comprehensive kinetic model called anaerobic digestion bacteria algae (ADBA) was developed to describe and predict the complex algae-bacterial system in anaerobic digestion (AD) wastewater under mixotrophic growth conditions. The model was calibrated and validated using the experimental growth data from cultivating the algae (Chlorella vulgaris CA1) with its indigenous bacteria in Blue Green 11 (BG-11) media and different combinations of sterilized, diluted, and raw AD effluent. Key parameters were obtained, including the distinct maximum growth rate of algae on CO2 (, 1.23 per day) and organic carbon (, 3.30 per day), the maximum growth rate of bacteria (µb, 1.20 per day), along with two noble parameters, i.e., the algae-bacteria interaction exponent (n, 0.03) and the growth inhibition coefficient (ae = 30 000 mg/L per AU) due to effluent turbidity. The model showed a good fit with an average R2 = 0.90 in all cases adjusted with 25 kinetic parameters. This was the first model capable of predicting algal and bacterial growth in AD effluent with their competitive interactions, assuming shifting growth modes of algae on organic and inorganic carbon under light. It could also predict the removal rate of substrate and nutrients from effluent, light inhibition due to biomass shading and effluent turbidity, mass transfer rate of O2 and CO2 from gas phase to liquid phase, and pH-driven equilibrium between dissolved inorganic carbon components (CO2, HCO3–, and CO32–). Algal growth in the strongly buffered AD effluent resulted in odor removal, turbidity reduction, and the removal of ∼80% of total ammonium-nitrogen and 90% of organic carbon. In addition to process parameter prediction, this study offered a practical solution to wastewater treatment, air pollution, and nutrient recycling, ensuring a holistic and practical approach to ecological balance.

This study investigated the effects of torrefaction on forest residue (FR) and its subsequent application as a bulk-loading filler in polylactic acid (PLA) composites. Torrefaction enhanced the chemical properties of FR, improving its compatibility with PLA, and the crystallinity increased from 24.9% to 42.5%. The process also improved the hydrophobicity of PLA/biomass composites, as demonstrated by the water contact angle of 76.1°, closely matching that of neat PLA (76.4°). With the introduction of 20% modified biomass properties after torrefaction treatment, the tensile strength of PLA/biomass composite increased from 58.7 to 62.3 MPa. Additionally, the addition of torrefied forest residue (TFR) accelerated biodegradation by increasing the onset of degradation and inhibiting crystallization. After 90 d, the biodegradability of PLA/biomass composites reached 94.9%, which had a 6.9% increase compared to the neat PLA (88.8%). Overall, this study highlights the potential of torrefaction in enhancing both the physical properties and biodegradability of PLA-based composites, contributing to a more sustainable approach to reducing plastic pollution.

Papermaking, a cornerstone of human civilization and one of China's Four Great Inventions, exemplifies the enduring legacy of ancient ingenuity in shaping modern materials science. Originating from the groundbreaking work of Lun Cai and his team, the papermaking process involves the meticulous disassembly, refinement, and reassembly of natural fibers into cohesive sheets: a process that, while refined, has remained fundamentally unchanged for nearly 2 000 years. This work explores the pivotal role of papermaking in contemporary society within the broader context of materials science, highlighting its fundamental principles and the remarkable versatility of its scalable process. Papermaking, once central to the dissemination of knowledge worldwide, has now evolved into a key player in the sustainable production of environmentally friendly products, touching every aspect of modern life. The principles underlying papermaking have inspired the development of novel materials, with techniques such as vacuum filtration paving the way for innovations like nanopapers based on a diverse group of building blcoks. Looking ahead, the field presents significant opportunities in sustainable sourcing, the creation of eco-friendly packaging, and the development of advanced materials with applications in healthcare and beyond. The enduring relevance of papermaking lies in its adaptability, versatility, and boundless potential for future innovation.

Many effective pretreatment methods (such as dilute acid, dilute alkali, ionic liquids, etc.) have been developed for lignocellulose upgrading, but several defaults of low working mass, high sugar loss and extra cost of solid-liquid separation and water washing hinder their large-scale application in industry. Besides, the valorization of lignin-rich residue from pretreated biomass after hydrolysis or fermentation greatly contributes to the economy and sustainability of lignocellulosic biorefinery, which is usually underestimated. This study developed a densification pretreatment with binary chemicals (densifying lignocellulosic biomass with sulfuric acid (SA) and metal salt (MS) followed by autoclave treatment ((DLCA(SA-MS)), which was conducted under mild condition (121 °C) with a biomass working mass as high as 400 kg/m3. The DLCA(SA-MS) biomass achieved over 95% sugar retention, 90% enzymatic sugar conversion and a high concentration of fermentable sugar (212.3 g/L) with superior fermentability. Furthermore, bio-adsorbent derived from DLCA(SA-MS) biomass residue was highly adsorptive and suitable for dyeing wastewater treatment, providing a feasible and eco-friendly method for lignin-rich residue valorization. These findings indicated that DLCA(SA-MS) pretreatment enables the full-component utilization of biomass and boosts the economic viability of lignocellulosic biorefinery.

Lignin serves as a promising Ultraviolet (UV) absorber within sunscreen industry. However, the commercial development of lignin-containing sunscreens faces challenges due to their low sun protection factor (SPF) and dark color in cosmetics industry. In this study, dual modifications on the chemical and physical structures of lignin were conducted to address these challenges. Initially, methylene bis-benzotriazolyl tetramethylbutylphenol (MBBT) was grafted onto alkali lignin (AL) through an atom transfer radical polymerization reaction, resulting in a polymer of AL-graft-MBBT3 (AL-g-MBBT3). The sunscreen prepared with 10% AL-g-MBBT3 displays outstanding sun protection performance with a SPF of 42.93 and a light color with a color difference value (ΔE) of 45.6, in contrast to 10% AL with a SPF of 4.74 and a ΔE value of 49.5. Subsequently, AL-g-MBBT3 was transformed into normal submicron spheres (AL-g-MBBT3 N) and TiO2-loading submicron spheres (AL-g-MBBT3/TiO2). The sun protection performances of 10% AL-g-MBBT3 N@C and AL-g-MBBT3/TiO2@C sunscreens obviously surpass that of AL-g-MBBT3@C sunscreen, achieving SPFs of 60.38 and 66.20, respectively. Additionally, there is a considerable improvement in the color of these sunscreens, with ΔE values of 41.8 and 36.3, respectively. These results provide valuable insights into exploring lignin's high-value applications in sunscreen.

Cavitation in water only, no matter whether hydrodynamic or acoustic, is a zero-waste circular economy process to convert industrial citrus processing waste into high-performance polysaccharides in high demand in a single-step at room temperature and ambient pressure using a modest amount of electricity as the only energy input. Following previous reports in which we used hydrodynamic cavitation, we now use an industrial acoustic sonicator to demonstrate the general viability of cavitation to convert biowaste residue of the industrial squeezing of pigmented sweet orange (Citrus sinensis) into highly bioactive “IntegroPectin” pectin and micronized cellulose “CytroCell”.

Selective conversion of biomass into targeted molecules like polyols, especially, from cellulosic compounds, is being widely investigated as a sustainable process to produce biodiesel and bio-additives. The known process involves two steps, namely hydrolysis and hydrogenation. Thus, it requires two different catalytic materials or bifunctional catalysts. In this context, the present work reports a new catalytic approach based on the use of tandem catalysts, consisting of the combination of an acid solid catalyst (active for hydrolysis) and a supported metal catalyst (active for hydrogenation). Two different functionalized activated carbons and the resin Amberlyst 15 have been tested as solid acid catalysts, and Ru nanoparticles supported on the original activated carbon (SA) are the metal catalyst part of the tandem. All the tested tandem catalysts exhibited higher activity than the supported Ru catalyst did. The highest cellulose conversion and selectivity to sorbitol (70% and 86%, respectively) have been obtained over a novel tandem catalyst, which resulted from a physical mixture between a sulfuric acid modified SA carbon (SASu) and Ru loaded SA (Ru/SA), leading to a tandem catalyst (Ru/SA+SASu). This novel-designed tandem catalyst is reusable. Based on tandem catalysts with a solid-solid system combination, the adopted novel-designed catalytic approach is cost-efficient and sustainable, and can be considered promising for the green production of high-added-value chemicals.
