Intensive agriculture, which is necessary for rapid food production, has changed the microbiota and soil stability. Therefore, maintaining efficient production requires disinfecting fumigants to control pests and vermin that infest soil. Garlic-based agrochemicals, such as dimethyl disulfide (DMDS) have a high pest control capacity. However, it is vital to control the high volatility of the fumigant during its application, making the use of plastic membranes for gas containment necessary. Despite the advantages offered by these membranes in the agricultural sector, their plastic composition has a negative effect on the environment if it is not used with an optimized method. The life extension of fumigant containment membranes is limited to a single use per application. Therefore, in this study, the possible reuse of three membrane types for DMDS fumigation was investigated to promote waste reduction. The barrier to the gas permeability of the membranes was measured as described in ASTM E2945–14. The stability of the plastic film in the presence of the DMDS fumigant was assessed by monitoring changes in the surface by atomic force microscopy and in the plastic microstructure by ASTM D638 and oxidative induction time analysis (ASTM D3895–19) using a differential scanning calorimeter.

The aqueous-phase hydrogenation of furfural to furfuryl alcohol using non-noble metal catalysts is constrained by the low activity of catalysts, necessitating high temperatures and high hydrogen pressures, and posing challenges in controlling furfuryl alcohol selectivity. Herein, a Co nanoparticle catalyst supported on nitrogen-doped carbon derived from MOFs is reported, which adopts a synergistic strategy to enhance catalytic performance. The nitrogen doping simultaneously promotes hydrogen spillover on the catalyst surface and reduces surface acidity, thereby suppressing acid-catalyzed side reactions. This dual function enables the selective hydrogenation of -C = O groups to -CH2OH groups in water under mild conditions. Furfural reached 98% conversion with 95% selectivity of furfuryl alcohol at 135 °C and under hydrogen pressure close to atmospheric (0.4 MPa) in 2 h. This study allows a low energy-consuming method for producing furfuryl alcohol from hemicellulose-derived furfural, and provides a promising strategy for the conversion of renewable biomass-derived compounds into high value-added chemicals.

As the world’s largest palm oil producer, Indonesia significantly benefits from its palm oil industry but also faces serious environmental challenges from palm oil mill effluent (POME)—a high-strength wastewater containing substantial organic matter, nutrients, suspended solids, and various chemical compounds. Sustainable and effective wastewater treatment strategies are urgently needed to address this issue. This review presents a comprehensive analysis of existing POME treatment technologies, including anaerobic digestion (AD), advanced oxidation processes (AOPs), membrane filtration, adsorption, phytoremediation, and microalgae-based systems. Each method is examined in terms of treatment efficiency, operational feasibility, and potential for implementation under Indonesian conditions. While advanced processes, such as AOPs and membrane filtration, achieve high pollutant removal, they are often limited by operational costs. In contrast, biological approaches, such as AD and phytoremediation, offer both environmental benefits and economic value through the recovery of biogas, biofertilizers, and biomass. This review highlights the potential for integrating wastewater purification with resource recovery and valorization, supporting a shift toward more circular and sustainable management of POME. The insights provided are intended to guide future research, inform policy decisions, and facilitate the industrial adoption of optimized treatment systems.

This study investigates the leaching and purification processes for dunite slurry, a common mining waste material, and the carbonation processes for the mineralization of CO2 with . Results indicate that HCl is a promising leaching agent, and pH and temperature are major factors in controlling the efficiency of the leaching process, with leaching efficiencies of 82% achieved after 4 h using 2 M HCl solution at 75 °C. The removal of other ions like , , and through the purification of the leachate using ammonium hydroxide was also proven to be effective, completely removing iron and aluminum from the leachate from starting concentrations of 3.10 and 0.40 g/L, respectively. The carbonation of magnesium at room temperature was investigated with both purified leachate and pure MgCl2 aqueous solution. Nesquehonite crystals began to form after 1.5 h with a conversion of to nesquehonite of approximately 5%. The produced crystals possess a needle-like shape, which could be modified using the biopolymers pectin and xanthan. Pectin had a limited influence on the length of the crystals, reducing the needle length with increasing pectin concentration. Xanthan, on the other hand, shortened and widened the needle-like structure into a column shape as more xanthan was added. This study demonstrates the potential for this process to utilize mining wastes and sequester CO2, producing useful mineral products in the process.

Conventional natural rubber (NR) fillers pose several environmental concerns. This study presents the sustainable development of NR composites incorporating sugarcane leaf (SCL)-derived alkali lignin and commercial alkali lignin as functional fillers. The primary objective was to evaluate the mechanical properties, aging resistance, thermal stability, and antimicrobial activity of the NR composites. Various NR composites were prepared by different filler types, including KOH-extracted SCL lignin, commercial alkali lignin, and butylated hydroxytoluene (BHT). The results show that NR composites containing KOH-extracted SCL lignin exhibited superior mechanical properties (crosslink density 126 mol/m3), improved aging resistance (aging coefficient 80.08 %), and enhanced thermal stability (the thermal degradation with 50 % weight loss (T50) and the highest degradation rate occurs (Td) of 394 and 383 °C, respectively) compared to all other samples. NR composites with commercial lignin demonstrated the highest reduction in Staphylococcus aureus populations (56.25 %). The NR composites with KOH-extracted SCL lignin displayed limited antimicrobial efficacy (37.78 %), suggesting that its primary contribution lies in mechanical and thermal reinforcement rather than microbial inhibition. These findings highlight the potential of eco-friendly lignin from SCL biomass as a sustainable bio-based filler for NR composites.

Catalysts Fe2O3-Al2O3 with high Fe2O3 contents (50–90wt%) were prepared by co-precipitation method and tested for methane decomposition and production of high-purity carbon nanofibers (CNFs). Catalytic tests were conducted in a fixed-bed reactor at atmospheric pressure, different temperatures and high CH4 space velocities. The catalytic tests performed at 700 °C showed that Fe2O3-Al2O3 catalysts containing 60–80wt% Fe2O3 enable a maximal CH4 conversion of around 56 % and production of CNFs with a purity above 95 %. Further, the catalytic results recorded over 80 % Fe2O3-Al2O3 catalyst at varied temperatures and space velocities revealed the following: (1) increasing temperature leads to an increased maximum CH4 conversion but a reduced CNFs productivity per unit weight of catalyst, and (2) CNFs productivity can be maximized at each temperature by lowering CH4 space velocity to an appropriate rate through reducing CH4 feed rate or increasing the amount of catalyst fed in the reactor. Moreover, typical SEM, Raman and TEM characterization results confirmed that the CNFs obtained are of a relatively narrow diameter distribution of 20–40 nm and graphitic nanostructure in appearance. Furthermore, electroconductivity measurement of typical CNFs products confirmed their good electrical conductivity, suggesting their potential direct use for formulation of anti-static CNFs reinforced plastic composites.

A CuSiAlOx catalyst was prepared through infrared-heating calcination and employed to catalyze vapor furfural (FFR) hydrogenation in a fixed-bed reactor. Its catalytic performance was systematically evaluated and compared to that of a catalyst derived from the same precursor but calcined using an electric oven. The hydrogenation tests were performed at temperatures varying in 140 ∼ 180 °C, H2/FFR (mol/mol) ratios in 4:1 ∼ 8:1, and liquid hourly space velocity (LHSVs) in 0.6 ∼ 1.0 h-1. The catalyst CuSiAlOx-IH (prepared by infrared-heating calcination) demonstrated higher FFR conversion than CuSiAlOx-EH (prepared by electric-oven heating) did. Under the conditions of a H2/FFR ratio of 6:1, a temperature of 140 °C, and an LHSV of 0.6 h-1, the CuSiAlOx-IH catalyst achieved a 99.70 % FFR conversion and 95.72 % selectivity to furfur alcohol (FOL) in a continuous test for 18 h. This time duration with good stability was twice longer than that enabled by CuSiAlOx-EH. Characterization of the fresh, reduced, and spent catalysts revealed that the catalyst CuSiAlOx-IH, compared to CuSiAlOx-EH, possessed more Cu defects, a higher BET surface area, a smaller average size, and the narrower size distribution of active-species particles. These structural advantages thus rendered the CuSiAlOx-IH catalyst superior in its catalysis of the FFR hydrogenation reactions.

The rapid development of portable electronics, wearable technologies, and healthcare monitoring systems necessitates the innovation of flexible energy storage systems. Considering environmental pollution and the depletion of fossil resources, the utilization of renewable resources to engineer advanced flexible materials has become especially crucial. Cellulose, the most abundant natural polymer, has emerged as a promising precursor for advanced functional materials due to its unique structure and properties. Typically, the easy processability, tunable chemical structure, self-assembly behavior, mechanical strength, and reinforcing capability enable its utilization as binder, substrate, hybrid electrode, separator, and electrolyte reservoir for flexible energy storage devices. This review comprehensively summarizes the design, fabrication, and mechanical and electrochemical performances of cellulose-based materials. The structure and unique properties of cellulose are first briefly introduced. Then, the construction of cellulose-based materials in the forms of 1D fibers/filaments, 2D films/membranes, 3D hydrogels and aerogels is discussed, and the merits of cellulose in these materials are emphasized. After that, the various advanced applications in supercapacitors, lithium-ion batteries, lithium-sulfur batteries, sodium-ion batteries, metal-air batteries, and Zn-ion batteries are presented in detail. Finally, an outlook of the potential challenges and future perspectives in advanced cellulose-based materials for flexible energy storage systems is discussed.

Two-dimensional (2D) CuS/Cu9S5 nanostructures are quite popular owing to their intriguing electrochemical properties. In-situ hydrothermal deposition of 2D CuS/Cu9S5 nanostructures on nickel foam at different pH was studied. The X-ray diffraction analysis confirmed two different stoichiometric forms, namely CuS and Cu9S5, in different proportions with a change in the synthesis pH. Morphological and compositional analysis exhibited a strong impact of pH on the CuS/Cu9S5 deposits. The samples prepared at pH 6.5 presented less agglomerated and densely distributed 2D nanosheets. Transmission electron microscopic studies under high resolution for the deposits synthesized at pH 6.5 showed hexagonal CuS and rhombohedral Cu9S5 particles of 32 nm average particle size. The electrochemical characterization of the samples for energy storage devices by cyclic voltammetry (CV) study revealed the specific capacitance from 1781 Fg−1 to 1589 Fg−1 at 10 mVs−1. The findings of CV and galvanostatic charge/discharge (GCD) analysis matched well. Rate capability studies showed the values between 72.9% and 50.24% at 7.5 Ag−1 for various samples. The sample prepared at pH 6.5 exhibited 73.07% of its starting capacitance at 10 Ag−1 after 2500 charging and discharging sequences. Electrochemical impedance spectroscopy runs (EIS) showed the existence of two constant phase elements (CPE) in series and the relaxation time constants from 0.01 to 0.5 seconds, which are preferred for energy storing purposes. Symmetric supercapacitor device prepared from sample deposited at pH 6.5 displayed 29.16 Wh energy per kg of material and a power density of 900 W kg−1, highlighting its suitability for high-efficiency energy storage applications.

Gasification is a highly effective technology for converting biomass into fuel gas or syngas. While various gasifiers have been commercialized for fuel gas production, mitigating tar formation in gasifiers remains challenging. This review is devoted to summarizing the general strategies adopted in various gasifiers to reduce tar formation for high-efficiency clean gasification. For single-bed and staged-gasification processes, their low-tar strategies are typically different. In the single-bed processes, the low-tar strategies involve in-bed intensification achieved by controlling flow directions of gas and particles inside the gasifier. During the gasification, these two components often have different temperatures to facilitate thermochemical interactions between them. Meanwhile, the two-stage gasifiers are generally designed to decouple pyrolysis, gasification and tar cracking reactions for maximizing the benefits (such as yield and efficiency) realized from the interactions among these reactions. In addition to minimizing tar formation, the approach of reaction decoupling can also raise the calorific value of product gas, even without use of oxygen, and/or improve the adaptability of gasification technology to the feedstocks with various moisture contents and particle sizes. The reanalysis based on those essential low-tar strategies is expected to gain alternative insights into the reaction principles implicated in most advanced biomass gasification technologies.
