Abstract

The growing demand for sustainable solvents and bio-based chemicals has heightened interest in renewable alternatives to petroleum-derived compounds. This study demonstrates an efficient and eco-friendly route for producing 2-methyltetrahydrofuran (2-MTHF) from Gmelina arborea leaves, a widely available lignocellulosic biomass. Thermal hydrolysis was conducted at 80 °C and atmospheric pressure using barium chloride as a low-cost catalyst. The reaction pathway proceeds through hemicellulose depolymerization to pentoses, dehydration to furfural, and subsequent hydrogenation–cyclization to yield 2-MTHF. Reaction time was optimized between 10–50 minutes, with Gas Chromatography-Mass Spectrometry (GC–MS) confirming a maximum yield of 19.47% (951.95 mg/g) at 50 minutes. The yield profile exhibited two distinct maxima, reflecting a balance between efficient conversion and secondary degradation reactions. Compared to conventional noble-metal-based hydrogenation processes, this method eliminates the need for high-pressure hydrogen and costly catalysts, thereby lowering energy intensity and production costs. The approach valorizes an underutilized agricultural residue, reduces environmental impact, and aligns with green chemistry principles. These findings highlight the potential of Gmelina arborea leaves as a sustainable feedstock for scalable 2-MTHF production, supporting its application as a green solvent, biofuel additive, and versatile platform chemical. Future work will focus on catalyst optimization, kinetic modeling, and techno-economic evaluation to advance industrial applicability.

Abstract

This study involved the determination of water-soluble and fat-soluble vitamins in margarines marketed in Nigeria. The vitamin content was quantified using UV-visible spectrophotometer along with standard procedures. The results obtained showed vitamins A, D, E, B (1,2,3,6 and 12), and C were detected in most of the samples analyzed, and the most predominant vitamin in all the margarine samples was vitamin E, which ranged from 2.03-3.45 mg/100g, with sample M3 having the least content, and sample M7 having the highest content, the second most predominant vitamin was vitamin C, ranging from 0.75-1.42 mg/100g, with sample M6 having the least content and sample M1 having the highest content. The other vitamins were in the following ranges: vitamin A (0.00-0.46 mg/100g), D (0.02-0.13 mg/100g), B1 (0.006-0.032 mg/100g), B2 (0.012-0.023 mg/100g), B3 (0.39-0.66 mg/100g), B6 (0.18-0.33 mg/100g), and B12 (0.00-0.14 mg/100g). The most common vitamin in all the margarine samples was vitamin E, ranging from 2.03 to 3.45 mg/100g. Sample M7 had the highest content and also provided the most overall vitamins, followed by sample M1, which had the highest levels of vitamins C, , and . These findings suggest that Nigerian margarines contain significant amounts of vitamins, especially vitamins E and C, and may provide a small boost to dietary vitamin intake.

Abstract

The consumption of contaminated water, especially those polluted by heavy metals, effluents, radioactive waste, etc., has posed a significant health risk in most developing economies. Therefore, researchers nowadays strive to ameliorate this menace. Hence, this study analyzed the concentration of Radon-222 in twenty drinking water samples collected from boreholes in Nigeria to provide insight into the concentration distribution of Radon-222 in the northwestern part of Nigeria. The Radon-222 concentrations in borehole water samples collected from Lagos and Ogun states were measured using a liquid scintillation counter at the Center for Energy Research and Training (CERT) in Ahmadu Bello University, Zaria. Radon concentrations for borehole water collected from 10 locations in Lagos State range between 51.78 Bq/L and 118.88 Bq/L, while those obtained from 10 selected locations in Ogun State range between 12.92 Bq/L and 110.26 Bq/L. The recorded mean values of radon concentrations obtained in this study for the borehole water in the two States were found to be above the world average Maximum Contamination Level (MCL) of 10 Bq/L set by the World Health Organization and the MCL of 11.1 Bq/L set by the United States Environmental Protection Agency (USEPA).

Abstract

This study examines the effectiveness of fiscal policy in promoting the adoption of green chemistry technology in Indonesia’s chemical industry sector using content analysis of 48 official secondary documents from 2018–2024. The analysed documents include regulations issued by the Minister of Finance, incentive realisation reports from the Directorate General of Taxes (DJP), investment data from BKPM, PROPER reports from the Ministry of Environment and Forestry (KLHK), sustainability reports of chemical companies listed on the Indonesia Stock Exchange (BEI), and international references from UNEP, OECD, and ICCA. The findings reveal that, despite the availability of various fiscal incentives (super deduction tax of up to 300%, tax holidays, and tax allowances), only 2.8% of the total incentives absorbed by the chemical sector in 2024 were actually directed toward green chemistry activities—significantly lagging behind Germany (31%) and South Korea (28%). The low uptake is primarily caused by the deferred nature of the incentives, convoluted and time-consuming application procedures (taking more than nine months), and the lack of clear technical definitions of green chemistry in existing regulations. These results are supported by pecking order financing theory (Myers & Majluf, 1984), prospect theory (Kahneman & Tversky, 1979), and the push-pull framework of environmental innovation (Horbach et al., 2012). The study recommends a paradigm shift in fiscal policy toward upfront instruments, namely refundable tax credits of 30–40%, VAT exemptions on bio-based raw materials, and direct grants; simplification of procedures into a one-stop service with a maximum approval time of four months; and revision of Minister of Finance Regulation (PMK) No. 153/2020 by including explicit technical definitions of green chemistry. These measures are expected to accelerate Indonesia’s chemical industry sector in achieving the Net Zero Emission target by 2060.

Abstract

For over the last ten years, the Tanatar oil and gas field has seen considerable reduction, therefore highlighting the urgent need for efficient stimulation methods to bring reservoir production back up. The fundamental issue under investigation here is the deteriorating performance of already existing wells and the dearth of comprehensive modeling analyses analyzing hydraulic fracturing under the particular geological circumstances of the site. This paper aims to investigate the hydraulic fracturing technique employing an sophisticated numerical modeling technique able of simulating interparticle dynamics, fracture initiation, propagation behavior, and fluid–solid interactions. The research reproduces the microscopic phenomena controlling hydraulic fracturing using a discrete-element-based modeling technique combined with fluid flow simulation. Representative reservoir characteristics were employed to calibrate the computational model, which then simulated stress distribution, crack development, pressure evolution, and resultant changes in permeability. Under several operational scenarios, this approach enables precise prediction of fracture geometry and reservoir reaction. According to the data, wellbore deliverability is improved and hydraulic fracturing greatly increases permeability inside the low-productivity zones of the Tanatar field. The simulations show obvious correlations between injection pressure, fracture propagation patterns, and stimulated reservoir volume. Moreover, the modeling shows that effective and secure extension of the economic life of exhausted reservoirs via hydraulic fracturing is conceivable. To conclude, the study offers the first thorough numerical evaluation of hydraulic fracturing for the Tanatar field and shows its great possibility as a productivity-enhancing strategy. The results give field operations useful direction and support the use of hydraulic fracturing as a practical stimulation technique in comparable low-permeability formations.
