    Data from a survey of 21 European nations from 2006 to 2018 investigates the relationship between economic development and carbon dioxide emissions. The PCA of normalised factors is used to create three quantitative measures for financial intermediation dependent on the results of the study. When estimating the framework, we used the Hoechle method, which generates systematic deviation for linear panel styles that really are not homoskedasticity coherent and moreover resistant to broad types of cross-sectional dependency. We observe that earnings, resource utilization, industrialization, urbanisation, foreign direct investment, and the banking system all seem to have contributed to increased carbon dioxide emissions in the area. However, greater economic access appears to have resulted in a reduction in greenhouse gas emissions. In terms of quality, the results are resilient to a variety of alternative proxies for financial inclusions as well as acceptable changes to the conceptual framework. According to the empirical findings, there are currently no regulatory interactions linking increasing economic development and reducing carbon dioxide emissions at the national level. As a result, economic growth should be incorporated into the implementation of sustainable green economy plans at the municipal, provincial, and city levels, particularly to counteract the documented detrimental impact of higher carbon dioxide emissions associated with increased financial inclusion.

    Healthcare supply chains are under pressure to drive down costs because of digital business, shifting customer needs and new competition. Medical waste generated from medical facilities includes medical activities and daily-life activities of patients and their family members. According to statistics of the Department of Health EnvironmentalManagement, Vietnam currently has more than 13,500 medical facilities, including hospitals from central to provincial and district levels and private hospitals and medical facilities. Preventive medicine generates about 590 tons of medical waste/day and is estimated to be about 800 tons/day. Medical waste includes ordinary medical waste and hazardous medical waste; in which ordinary medical waste accounts for about 80%–90%, only about 10%–20% is hazardous medical waste including infectious waste and non-infectious hazardous waste. This is an environmental and occupational health issue that needs attention in developing countries like Vietnam. Handling large amounts of medical waste to ensure environmental and personal hygiene, doing so inefficiently creates potential hazards to the environment and increases operating costs. However, hospitals lack objective criteria and methods to evaluate and select the most optimal infectious medical waste, relying instead on their own subjective assessment and prior experience. Therefore, the author proposed a fuzzy multicriteria decision making (MCDM) model including Fuzzy Analytic hierarchy process (FAHP) and the Weighted Aggregated Sum-Product Assessment (WASPAS) for infectious medical waste contractors’ selection in this research. The proposed FuzzyMCDMmethod is in-tended to provide a more efficient, accurate method in the selection of infectious medical waste contractors than subjective assessment methods, thus reduce potential risks to hospitals. The results of this study can be applied to evaluate and select contractors in other industries.

    Thermal generation facilities (TGFs) play a vital role in supplying heat to industrial manufacturing processes. In addition to fuel consumption, the majority of which are fossil fuels, TGFs produce bottom and fly ash (BFA) that could be utilized. The objective of this study is to assess the production and management at source of the BFA to propose appropriate management solutions. Based on HEPZA’s database, a questionnaire survey was conducted among 179 enterprises. Data was analyzed using descriptive statistics. The result revealed a total BFA production of 1,606.22 tons per month. At most enterprises, the bottom ash and fly ash were not separated. 33 companies involved in the collection, transportation, treatment, and recycling of BFA at 61 enterprises, showing a dispersed BFA handling system that may disadvantage the control of BFA pathways for reuse. This study proposed solutions to enhance BFA utilization via managing the BFA at source as well as the collection, transportation, treatment, and recycling facilities.

    The Vietnamese government has decided to use and promote the development of more renewable energy sources, particularly wind energy. When implementing a wind energy project, choosing a wind turbine supplier is an important decision and investors must find the optimal supplier through evaluating many qualitative and quantitative criteria that affect each other symmetrically. Therefore, the process used for selecting a wind turbine supplier in wind power projects is a multi-criteria decision-making process. Many approaches have been applied for this decision process, some of which are based on multicriteria decision-making (MCDM) methods, whether applied individually or in combination with other MCDM models. In this study, the researchers proposed a decision-making model based on spherical fuzzy sets for wind turbine supplier selection in wind power energy projects. In this paper, Vietnam is used as a case study. The recommended turbine suppliers for installations can finally be generated after the calculations in the final stage of this research. The contribution of this research is developing a fuzzy MCDM model for suitable turbine suppliers in wind power energy projects. The results of this study can be used as references for experts in deciding on a suitable wind turbine supplier in other countries as well as in other renewable energy projects.

    Aqueous extract of seaweed Enteromorpha prolifera was used to synthesize Silver Nanoparticles (AgNPs). The reaction mixture turns brown when AgNPs are formed in it. UV–VIS, FTIR, XRD, EDAX and DLS with Zeta potential techniques were used to characterize the green synthesized AgNPs. AgNPs exhibited an absorbance band at 448 nm in the UV–Vis spectrum. FTIR spectrum registered 11 intense peaks with distinct functional groups. AgNPs display an XRD pattern with 8 peaks, and the average grain size was 17.8 nm. FESEM analysis shows that AgNPs are polydispersed and spherical. EDX results revealed a strong signal peak at 3 keV due to silver presence. The Zeta potential of AgNPs was 30.88 mV, which indicates their stability. The growth of the seedling was positively affected by certain concentrations of AgNPs. In DPPH, the lowest "IC50" value against algae extract was 133.33 g/mL, compared to 142.0 g/mL for algal AgNPs. Increased AgNPs concentrations reduce the earthworms' death time in toxicology studies.
