Effect of Temperature and Gas Flow Rate on CO2 Capture
European Journal of Sustainable Development Research, 2022, 6(2), em0181,
ABSTRACT: In this study, the removal of carbon dioxide (CO2) that has a huge contribution to global warming from gas emissions was performed using absorption method. Effect of operational parameters such as temperature and gas flow rate on the absorption capacity (g CO2/kg solvent and mol CO2/mol MEA) was investigated in a bubble column reactor with a semi-batch operation. The monoethanolamine (MEA) was used as a solvent and absorption capacity was determined at different gas flow rates (2.5 and 5 L/min) and temperatures (25-35-45 oC). Because of the study, absorption capacities of 74.71 g CO2 / kg MEA and 0.51 mol CO2/mol MEA were obtained at 5 L / min gas flow rate, 25oC and 20% solvent concentration. The absorption capacity increases as the temperature decreases and as the flow rate increases. Because of the study, it can be concluded that the capture of CO2 into the MEA solution at bubble column can be successfully achieved with high absorption capacity.

Determinants of Sustainable Use of Farmlands in Amhara Region, Ethiopia
European Journal of Sustainable Development Research, 2022, 6(2), em0182,
ABSTRACT: This study analyses determinants of sustainable use of farmlands in Debre Mawi and Densa Bahta rural kebeles of Amhara region in northwestern Ethiopia. Within the framework of qualitative research methodology, the case study approach adopted in the study. The required primary data were gathered through focus group discussions and in-depth interviews. A generic analytical framework that combines the sustainable livelihood framework (SLF) and the farming system model was used in this study to understand the synergy of multiple variables that mediate sustainable land management practice among study respondents selected from the case study kebeles. The study reveals the relative importance of productive asset endowments, self-efficacy and risk perception on the sustainable use of farmlands in the Amhara region. Interviewees that follow unsustainable farming practices were endowed with relatively lower pieces of farmland and disadvantaged in possession of other productive assets. They also demonstrated a low level of self-efficacy and a risk-averse attitude to adopting conservation technologies, as they possessed smaller sizes of farmland compared with the village and regional average. The productive asset holdings of land-poor farmers and opportunities for off-farm activities should thus be enhanced to halt the ongoing farmland degradation in Amhara region.

Sharp Teacher Training and the New Constructal Pedagogical Supervision Theory for Sustainable Development
European Journal of Sustainable Development Research, 2022, 6(2), em0183,
ABSTRACT: We live in the information age but we can only increase the benefit if we look to permanently promote more efficiently the use of the cyberspace for creative thinking; pedagogical innovation; sustainable development education; the new constructal pedagogical supervision; scientific, technological, and engineering advances share like the constructal law, green chemistry, and green energy; Portuguese Cultural Heritage; economic growth; and biotechnology through the quality pedagogical resources and Web 2.0 already putted in place in there and all those that are to come available. So more “state-of-the-art” teachers training for continuous update are needed, and we know too that adequate training can lead to better judgments and better performance. In Portugal, the pedagogical supervision theories thrive with lots of different institutions like universities and polytechnics offering MSc. and PhD programs in these subjects, to these theories is add now the constructal pedagogical supervision theory for sustainable development. New training courses are needed for teachers so can have a bigger variety for their choices, while achieving the United Nations goals for sustainable development.

Agricultural Biomass to Adipic Acid–An Industrially Important Chemical
European Journal of Sustainable Development Research, 2022, 6(2), em0184,
ABSTRACT: Adipic acid is widely used in the production of nylon, plasticizers, polyurethane resins, adhesives, lubricants, etc. and hence the compound annual growth rate of adipic acid is expected to be 4.4% with a market size of over USD 7,000 million. At present adipic acid is commercially manufactured using petrochemical feedstock like benzene, hexane, hexene, hexanone, etc. using nitric acid as the catalyst. The research community is exploring newer methodologies to synthesize adipic acid and other industrially valuable chemicals using renewable feedstock one of them being biomass. There are mainly two routes of synthesizing adipic acid from biomass–chemocatalytic and biological. Within these routes, there are a variety of processes like deoxydehydrogenation (DODH), hydrodeoxygenation, direct synthesis via oxidation-hydrogenation that help convert biomass to adipic acid. With heterogeneous catalysis as a developing domain, researchers have developed a variety of catalysts like zeolites, silica-based catalysts, biological catalysts, deep utectic solvents as catalysts and a variety of other heterogeneous catalysts that convert that biomass containing cellulose, hemicellulose, lignin, other sugars to adipic acid efficiently. The paper reviews all the methodologies, catalysts for conversion and market demand of adipic acid.

Proposal of a Global Handicraft Index for Sustainable Development: A Visionary Approach for Small Industry and Developing Strategies for Handicraft (Rural Industry)
European Journal of Sustainable Development Research, 2022, 6(2), em0185,
ABSTRACT: The purpose of this paper is to give a separate index for the development of handicraft products developing sustainable completion and better utilization of the natural and rural industry and better completion in handicraft industries, conserving the heritage of all countries handmade tradition, the skill of artisans, making them entrepreneurship to artisans. Among them, we know that whole world is facing a big problem of plastic glass and other population and climate is also affecting due to environmental pollution in the world so if all want to maintain their life and living patter better and sustainable then they should have to make the product for their utility that is sustainable and utility decorative and that will have to give local job and enhancing the local talent of the artisan and rural, tribal people special women. We know that all are worker but want to be entrepreneur and earn their mount and increase the GDP of their country and in last want to be happy in the world so the objective to the paper is to develop and innovation and suggest first global handicraft index like global innovation index, global happiness index, global hanger index, global environments risk assessment index, and other index that have help the world each country for developing and giving better competition between the other sector, and other sector so in case of handicraft sector that artisans, and worker ground completion’s, better development, capacity building of the artisan women empowerment in handicraft sector and in last socio-economic welfare of artisan and over global development the reviving of handicraft industry in the world that is facing huge problem in comparison of machine-made product in current scenario and to conserve our local talent, our heritage product, our tradition and ancient skill and monument and sustainability to product and eco-friendly living pattern of the people in whole world.

Time-Dependent Study of Air Ions in Multiple Zones of Urban Environment
European Journal of Sustainable Development Research, 2022, 6(2), em0186,
ABSTRACT: The level of air ions considers as an early detection tool for change in the environmental pollutants. The advancement in storage and transportation technology has increased the concentration of air ions in an urban environment. Significant literature reveals that if positive air ions are present in a large number, it has severe health impacts on the human body.
This paper discusses the seasonal scanning of air ions at a traffic junction and green zone. The spot sampling methodology used in this study and assessment of air ions count (AIC) during both summer and winter seasons in 2019 at Nagpur city, India. The study reveals that the critically polluted regions are season invariable concerning air ions as a precursor of pollution. The observation of fewer values in negative ions for both the summer and winter season in traffic intersections grounded the fact that seasonal washout of pollutants is not there, which is observed for green zones. The vehicle counts and its density in the green zone play a critical role in the concentration of negative ions. The air ion ratio (-/+) of the morning, afternoon, and the evening was 1.030, 1.142, and 1.142, respectively in the green zone and having lowest values in the traffic location (morning, afternoon, and the evening was 0.92, 0.83, and 0.77, respectively). The increment or decrement in the ion ratio could help understand the prevailing air quality scenario in the urban macro-environment.
