Abstract

Isopentanol (3-methyl-1-butanol) is a versatile higher alcohol with potential applications as a renewable fuel component and chemical intermediate. This study presents a sustainable route for producing isopentanol from fallen Gmelina arborea leaf biomass through barium chloride (BaCl2)-catalysed thermal hydrolysis under mild temperatures (60–90 °C) and atmospheric pressure. The approach integrates waste-biomass valorisation, renewable feedstock utilisation, and low-cost catalysis, thereby supporting the principles of a circular bioeconomy and contributing to Sustainable Development Goal (SDG) 12 (Responsible Consumption and Production) through the conversion of otherwise discarded leaf residues into a value-added chemical. It also supports SDG 7 (Affordable and Clean Energy) by exploring a renewable pathway to a higher alcohol with biofuel potential and SDG 9 (Industry, Innovation and Infrastructure) through the development of a simple catalytic conversion process. The effects of reaction temperature and catalyst loading (0.5–1.0%) were investigated, and products were identified and quantified by Gas Chromatography–Mass Spectrometry (GC–MS). Temperature (p = 0.0013) and catalyst loading (p = 0.048) significantly affected isopentanol yield, while their interaction was not significant. The highest measured yield in the experimental dataset was 452.8 mg/g at 80 °C and 0.5% BaCl2 loading. The results indicate that waste Gmelina arborea leaves can serve as a non-food renewable feedstock for higher-alcohol production, with potential environmental and resource-efficiency benefits consistent with SDGs 7, 9, and 12.

Abstract

Background: Clinics are essential primary healthcare facilities for maintaining lifesaving and routine services during disasters. Preparedness assessment is necessary to identify the capacity and gaps of each facility. Objective: This study analyzed and compared disaster preparedness across 17 clinics. Methods: A quantitative descriptive observational study with a multisite cross-sectional design was conducted in May 2026. Data were obtained through direct observation, interviews, document review, and facility documentation. The instrument included 30 indicators across six domains: policy and management, human resources, infrastructure, logistics, communication, and services. Each indicator was scored from 0 to 2, yielding a maximum score of 60. Results: Mean preparedness was 83.43%, with a median of 88.33%, a standard deviation of 12.42%, and a range of 56.67% to 100%. Thirteen clinics (76.47%) were categorized as highly prepared and four (23.53%) as moderately prepared. Major gaps concerned emergency alarms, evacuation maps, drills, disaster-response teams, emergency procedures, triage, emergency areas, backup power, referral coordination, and mass-casualty management. Conclusion: Most clinics demonstrated high preparedness; however, operational readiness requires stronger infrastructure, standardized procedures, recurring training, and simulation exercises. Addressing these gaps may contribute to SDG 3 by supporting continuity of essential health services, SDG 11 by strengthening urban disaster resilience, and SDG 13 by improving institutional adaptive capacity for disaster-risk management.
