The chemical industry is one of the largest consumers of fossil raw materials in the European Union (EU). Phasing out the use of fossil carbon both for energetic and material use (decarbonization/defossilization) requires the introduction of alternative processes and systems of production and consumption. One strategy that brings forward the defossilization of the chemistry sector is the use of biomass (bio-based carbon) as a raw material to produce bio-based chemical products. Our analysis focuses on the intersection of the forest-based bioeconomy, bio-based chemical production, and consumer preferences. It points out how the sustainability transition of the chemical industry changes the forest-based bioeconomy policy subsystem in the EU. Drawing on the Political process inherent Dynamics Approach (PIDA), we apply a mixed-methods research design that integrates three scientific perspectives in an interdisciplinary approach. We illustrate how shifts in forestry, the chemical industry, and consumer preferences change the forest-based bioeconomy policy subsystem. Numerous strategies and goals referring to international agreements have been introduced by the EU in recent years and new actors from the chemical industry are entering the policy subsystem. Yet, new instruments are needed and developed for the regulation of the carbon cycle and negative emissions. The study provides directions for research on the defossilization of the chemical industry through the use of forest biomass and points out potential conflicts and trade-offs in production, consumption, and regulation. © 2025 The Authors

Given the cost, time requirements, and limited accessibility of Locked Wheel Skid Trailer (LWST) testing, this research explores alternative approaches to predicting skid number (SN) using more affordable and readily available devices. These alternatives offer quicker results, which is particularly relevant given the standardized nature of skid number measurements worldwide. The study focuses on predicting the (SN) generated by the LWST test through analyzing data from Dynamic Friction Tester (DFT), British Pendulum Tester (BPT), and Circular Texture Meter (CTM) using statistical and machine learning techniques. The research includes a thorough assessment of various prediction methods and factors influencing skid number accuracy, including strategies for handling missing data. Prediction models employ Multiple Linear Regression (MLR), Support Vector Machine (SVM), Artificial Neural Network (ANN), and Ensemble Bagged Tree (EBT) techniques, utilizing predictors such as Dynamic Friction Number at 20 km/h (DFT20), Dynamic Friction Number at 64 km/h (DFT64), British Pendulum Number (BPN), and Mean Profile Depth (MPD). The development of forty-eight models, including Full, Reduced, and individual predictor models, involved employing data imputation methods and stepwise regression. Significant correlations were observed among friction parameters, with DFT20 showing the highest correlation with skid numbers, while MPD exhibited the lowest. Following data imputation, notable enhancements in BPN's correlation were noted. The study emphasizes the superiority of Full models in skid number prediction accuracy, with EBT models, especially those enhanced by data imputation, demonstrating outstanding performance. Statistical simulations confirmed the reliability of these models, indicating minimal outliers, overfitting, and high accuracy in skid number estimation. The prioritization of DFT over BPT and CTM is highlighted, with the potential for further exploration of devices to imp

In this study, the abilities of two of the most popular flood modeling software, namely, HEC-RAS and MIKE+, were used for flood modeling in the Hron River in East Slovakia. For modeling purposes, various discharge values of the River from one year to hundred years peak discharge were considered. The vulnerability of the catchment for each period was modeled and visualized using both software. The HEC-RAS and MIKE+ outputs showed that the study area is vulnerable to flood for high-frequency peak discharge values. The outputs of both 2D hydrodynamic approaches were found to be close to each other in various flow conditions. The comparisons of the MIKE+ and HEC-RAS showed that Hron River dimensions for the given catchment are only sufficient to transfer a one-year peak discharge value safely. The outputs of the models exhibited that the study area is not safe in case of ten-year peak discharge value and the risk of the floods getting the highest level in case of hundred-year peak discharge. Due to the models’ findings, it is seen that the area is vulnerable to flood, and three different mitigation scenarios were proposed and analyzed including change in river bed dimensions and rise of the levee on the right and left river bank to protect the area from flood risks. © 2025, The Authors.

Exploring the potential of advanced distillable solvents as efficient biomass pretreatment agents is critical for biorefineries, enhancing fermentable sugar yields while enabling solvent recovery and recycling without suffering significant losses. Here, we employ distillable amine-based solvents for pretreating a wide range of lignocellulosic feedstocks, aiming to facilitate the industrial release of fermentable sugars from diverse feedstocks through enzymatic hydrolysis. Twenty-two diverse feedstocks, sourced from different geographical regions and representing various biomass categories, were surveyed for chemical (mainly carbohydrates and lignin) and lignin (S, G, H units) profiles. Several solvents including ethanolamine, ethanolamine acetate, butylamine, butylamine acetate, and triethylamine, were tested for the pretreatment of eight selected biomasses. Among these solvents, butylamine emerged as the most effective due to its favorable sugar release, excellent solvent removal rate, and low boiling point, facilitating solvent recovery and recycling. Extending butylamine pretreatment to all 22 feedstocks demonstrated desirable sugar yields and highly efficient solvent removal in the majority of the biomass sources tested. Agricultural residues and their mixtures showed particularly favorable results. Scale-up experiments of the mixed agricultural feedstocks in a 1 L Parr reactor achieved over 90% glucose liberation and more than 99% butylamine removal, highlighting the method's scalability. The resulting hydrolysates supported growth of diverse bacterial and fungal strains, indicating downstream compatibility with commercial fermentation processes. This study presents butylamine as an effective, recoverable pretreatment solvent for a wide range of lignocellulosic feedstocks, offering a promising solution to key biorefinery challenges. The demonstrated scalability and compatibility with various biomass types and blends underscore its potential for industrial appli

This work describes the hydrothermal synthesis and characterization of zeolite 4A (Zeo-4A) and magnetite zeolite (Zeo-4A@Fe₃O₄) from Cameroonian raw kaolin. The study also explores the efficiency of Zeo-4A@Fe₃O₄ for the removal of quinoline yellow (E104) via Fenton process. XRD, FTIR, SEM, EDX, NMR-MAS and TGA-DSC characterizations show that Zeo-4A is crystalline with cubic morphology, while Zeo-4A@Fe₃O₄ exhibits a bonding interaction between zeolite and Fe₃O₄ nanoparticle leading to morphological structural changes. The degradation of quinoline yellow by heterogeneous Fenton process was carried out by varying several parameters, namely solution pH (3–7), H₂O₂ concentration (0.5–1.5 mol/L), quinoline yellow concentration (50–100 mg/L), and catalyst mass (50–100 mg). The results of catalytic performance tests reveal that the degradation efficiency of synthetic Zeo-4A, Zeo-4A@Fe₃O₄ and Fe₃O₄ were 1.71 %, 93.60 % and 92.65 %, respectively, after 60 min. Confirmatory tests were carried out by response surface methodology based on the Box-Behnken design, and a degradation rate of 98.81 % was obtained under optimum conditions of pH 3.84, 50.14 mg/L, 100 mg, and 1.5 g/L;which is well in line with the model predictions. A significant quadratic regression model R² = 91.35 % and the adjusted coefficient of determination value (adjusted R² = 82.04 %) were observed using the analysis of the variance. The study of catalyst recovery and reusability shows that the catalysts remain stable with a degradation rate greater than 66 % after five cycles. The kinetics results show that the degradation of E104 follows first and second order kinetic models, influenced by pH and catalyst mass, with optimum efficiency at pH 3. The characterization results of the material after degradation show that it maintains its stru

In the present study, an adsorbent material (N-dopped Cu/Al@Biochar) was synthesized by integrating N, Cu, and Al atoms into the structure of a biochar. This material was characterized by several physicochemical methods, then applied to the elimination of tetracycline (TC) and norfloxacin (NC). The results obtained showed that the modification method used, although significantly altering the mesoporous structure of the original biochar, generates several functional groups on the surface of the material, giving it excellent adsorption properties. These properties were evaluated by studying the influence of various experimental parameters such as the pH of the solution, the mass of doped biochar, and the contact time on the amount of antibiotic adsorbed. Adsorption studies revealed maximum amounts of TC and NC adsorbed of 65 and 96 mg/g at pH = 8 and 6 respectively with 50 mg of adsorbent for an equilibrium time of 90 min for TC and 60 min for NC at a concentration of 15 mg/L for both antibiotics. This adsorption capacity led to the removal percentages of up to 90 and 82% for TC and NC, respectively. After five cycles of use, a decrease in adsorption efficiency of 9% for TC and 11% for NC was observed, demonstrating the impressive stability of the synthesized material. Kinetic studies revealed that the Elovich and pseudo nth order models are the most appropriate to describe the adsorption kinetics of TC and NC respectively. In addition, the two- and three-parameter isotherm models used in this study revealed multilayer adsorption processes, based on both π-π, n-π, van der Waals bond formation and hydrogen bonds. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2025.

The optimal design of solid-state hydrogen storage devices is crucial for their effectiveness. This study investigates the thermal management of LaNi 5 -based metal hydride reactors for solid-state hydrogen storage by incorporating various fin materials: copper, aluminum nitride (AlN), and Aluminum Silicon Magnesium (AlSi10Mg). Utilizing ANSYS FLUENT 15.0 for simulations within a 2D numerical model, User-Defined Functions (UDFs) were employed to access the dehydrogenation process over a half-hour period. The reactor is subjected to an initial temperature of 363 K and heating oil is introduced at a speed of 1 m/s pressures ranging from 1 to 2 bar. The impact of different fin materials on enhancing the reactor's desorption properties was evaluated through key metrics such as hydrogen concentration, forced convection heat transfer coefficient, and average reactor temperature. Results demonstrate a remarkable improvement in hydrogen desorption rates, where copper fins achieve up to 67.6 % reduction in time to reach equilibrium at 1 bar compared to the reactor without fins. Similarly, AlN and AlSi10Mg fins exhibit a 64 % and 62 % reduction, respectively, highlighting their contributions to improved reactor performance. This research contributes to the advancement of hydrogen storage technologies by offering insights into the selection of fin materials and design for efficient.
