Mechanical testing demonstrated that the cellulose-reinforced film (BSC) achieved the highest tensile strength of 8.23 ± 0.05 MPa, a significant improvement over the pure starch film (3.19 ± 0.34 MPa). The chitin-reinforced film (BSC2) exhibited the maximum elongation at break (85.0 ± 1.06%) and the lowest water absorption (58.0 ± 0.03%). Furthermore, the collagen-reinforced film (BSC3) displayed the thinnest profile (0.25 ± 0.02 mm) and superior chemical stability, retaining 70% and 90% resistance in H₂SO₄ and NaOH environments, respectively. Soil burial tests indicated high biodegradability, with degradation rates ranging from 75 to 90% after 30 days, peaking in the chitin-reinforced formulation.

In this study, hierarchical porous BCs were synthesized from rapeseed (<i>Brassica napus L.)</i> stalks through carbonization followed by KOH activation at two different temperatures (600 °C and 800 °C). The activation temperature altered the surface and pore characteristics of the BCs, which in turn influenced their BSA adsorption and procaine loading–release behaviors. The BCs were then evaluated as a biosorbent to adsorb bovine serum albumin (BSA) and to load procaine, a model anesthetic drug. Notably, the biochar activated at 600 °C (RS6a) exhibited the highest protein adsorption capacity, while the sample activated at 800 °C and coated with BSA (RS8a-1:7) showed superior procaine release performance. All produced BCs demonstrated negligible cytotoxicity in fibroblast cultures, confirming their biocompatibility across a broad dose range.

The machine learning (AdaBoost) model accurately predicted the thermal decomposition behavior of CNWs prepared under different synthesis conditions (R² = 0.92).

Pretreatments are essential for improving the efficiency of biomass conversion into fermentable sugars. The use of ultrasound, for example, is an effective method that deconstructs the biomass, facilitating enzymatic hydrolysis. Apple pomace, a byproduct of the juice industry that accounts for about 30% of the total volume of apples processed, is rich in carbohydrates that can be converted into reducing sugars (RS). This study evaluated different pretreatments of apple pomace using either a probe or ultrasonic bath (exposure times of 30 or 60 min) to determine the optimal conditions for RS release during enzymatic hydrolysis. The effects of solid load, pulse number, and probe ultrasonic pretreatment time were assessed through experimental design, as well as the solid load, power, and time of the ultrasonic bath. Different enzymes (pectinase, cellulase, and hemicellulase) were evaluated for enzymatic hydrolysis after pretreatments. The results showed that the ultrasonic bath for 30 min with low power (30W) and low temperature (30 °C) was the most effective as pretreatment to enzymatic hydrolysis, especially with pectinase, which showed a hydrolysis efficiency of 85.06%, and cellulase, with an efficiency of 66.27%. The study demonstrates advancements in the efficiency of enzymatic hydrolysis after ultrasound pretreatment. Furthermore, it suggests that similar methods could be applied to different types of biomasses and investigated for scalability in industry.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":488,"journal":{"name":"Biomass Conversion and Biorefinery","volume":"16 15","pages":""},"PeriodicalIF":4.3,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13399-026-07235-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148751360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this research gap, this study employs the Box–Behnken Design (BBD) in conjunction with Response Surface Methodology (RSM) to optimize the production conditions of biochar–cardboard briquettes, focusing on three critical process parameters: humidity (10–20%), binder content (10–20%), and pressure (200–600 bar).

Through the development of second-order polynomial models, the influence of individual and interaction effects was evaluated. Statistical and graphical analyses (2D contour and 3D response surface plots) revealed that durability is enhanced by lower humidity, moderate binder content, and high pressure, while HHV is primarily influenced by the binder ratio, with minimal impact from humidity and pressure. Proximate and elemental analyses supported the optimization results, confirming that higher carbon and fixed carbon contents are associated with increased calorific value and improved combustion properties. A strong linear correlation was observed between fixed carbon and total carbon content.

Subsequently, the study analyzed the impact on economic performance of rice husk gasification and pyrolysis processes in Colombia’s Caribbean region. The study examined the procurement of raw materials through a logistics analysis based on supply routes. A hierarchical analytical process was used to identify suitable areas for the installation of bioenergy plants, and ArcGIS Pro was employed for this analysis. The results of the response surfaces showed that for pyrolysis products, the maximum bio-oil yield was observed at a temperature of 450 °C and a residence time greater than 3 s. For the optimization of biochar yield, the trend indicated that process conditions corresponding to higher temperatures and longer residence times should be explored. Regarding gasification, the results showed that optimization tends toward higher moisture content (> 6.24%) and an ER < 0.1, conditions that would not be consistent with actual process conditions.
