Controlled reprocessing of leucoxene concentrate for environmental friendly production of titanosilicate – An effective sorbent for strontium and cesium ions

An environmentally friendly synthesis procedure of titanosilicate with sitinakite structure from quartz-leucoxene concentrates processing products for effective sorption of strontium and cesium ions has been designed. The proposed method minimizes the environmental impact by controlling the acidity of waste waters and reuse of fluorammonium component in the technological process of enrichment (fluorination) of mineral raw materials. The sitinakite synthesis procedure excludes the stage of additional mechanical activation of quartz-leucoxene concentrate using complex and energy-consuming equipment. The precipitate composition and formation of SiO2-TiOn complex aggregates is controlled through step-by-step hydrolysis of dissolved forms of compounds. The new approach reduces sitinakite synthesis temperature and allows regulating composition, crystallinity and sorption properties of titanosilicate. The sorption capacity of the obtained sitinakite by Sr2+ and Cs+ cations is 120 and 170 mg/g, respectively, and does not decrease when its crystallinity changes.

The Nexus Between Green Entrepreneurship and Sustainable Development: An Econometric Study

Rising industrialization helps with economic growth and is responsible for environmental pollution as well as global warming. Here, green entrepreneurs play a significant role in the reduction of this environmental pollution and sustainable development. Although the study of green entrepreneurship and its relationship with economic, social and financial growth is limited and at a nascent stage. Therefore, this study examines the relationships among green entrepreneurship and credit policy, financial development, sustainable development goals and trade openness using the ‘Environmental Kuznets Curve (EKC) hypothesis’. From this perspective, 114 countries worldwide are considered and subdivided into three sub-categories, including lower-income, middle-income and higher-income countries, based on panel data collected from the World Bank’s database. Descriptive statistics, a cross-sectional dependence test, a unit root test, long-run estimations and a multicollinearity test have been used for the data analysis. The findings of the study show that green entrepreneurship decreases environmental pollution throughout the world and enhances financial development and credit policy around the world. Likewise, income per capita helps with credit policy, economic development and green entrepreneurship. Moreover, environmental factors are positively associated with financial development and sustainable development goals. Finally, the EKC hypothesis supports the relationship for all variables throughout panel and subpanel data. Additionally, these findings could help policymakers improve policies for managing environment-friendly products and enhance green funding, considering clean investment and other green aspects of sustainable development.

Bioconcentration and cellular effects of emerging contaminants in sponges from Maldivian coral reefs: A managing tool for sustainable tourism

Tourism is the main income source for the Maldives, but concurrently, it represents a growing threat to its marine ecosystem. Here, we monitored the bioaccumulation of 15 emerging contaminants (ECs) in the Maldivian reef sponges Spheciospongia vagabunda collected in two resort islands (Athuruga and Thudufushi, Ari Atoll) and an inhabited island (Magoodhoo, Faafu Atoll), and we analysed their impact on different sponge cellular stress biomarkers. Caffeine and the insect repellent DEET were detected in sponges of all the islands, whereas the antibiotic erythromycin and the UV filter 4-methylbenzylidene camphor were found in resort islands only. Although concentrations were approximately a few ng/g d.w., we quantified various induced cellular effects, in particular an increase of the levels of the enzyme glutathione S-transferase involved in cell detoxification. Our results highlight the importance to increase awareness on ECs pollution, promoting the use of more environmental friendly products to achieving the sustainable development goals.

The Role of Social Norms and Personal Costs on Pro-Environmental Behavior: The Mediating Role of Personal Norms.

Pro-environmental behavior necessitates individuals to make personal sacrifices, such as spending more money on environmentally-friendly products to benefit the environment. Realistically, individuals may not be willing to engage in pro-environmental behavior based self-interest. The increase in personal pro-environmental behavior has become an urgent issue in the field of environmental psychology. The present study adopted green consumption paradigm to explore the internal mechanisms of pro-environmental behavior at different personal costs, the role of social and personal norms on pro-environmental behavior, which can promote individual pro-environmental behavior. In our experiment, participants first were instructed to read texts unrelated and related to social norms in sequence. Participants subsequently completed the product choice task, which involved making choices between buying green (eco-friendly) products or cheaper (self-interested) common products, a method to measure pro-environment behavior. Finally, the participants completed the personal norms scale and social norms check. The findings of present study indicated that pro-environmental behavior decreased as personal costs increased. However, social norms effectively promoted individuals' pro-environmental behavior, and personal norms played a mediating role at high personal costs. Our findings indicate that individuals tend to choose cheaper common products that are harmful to the natural environment in self-interest. However, we discuss the implications for the use of social norms as a social marketing technique, which extends the Norm Activation Model.

Vinca alkaloids as a potential cancer therapeutics: recent update and future challenges.

Vinca alkaloids including vincristine, vinblastine, vindesine, and vinflunine are chemotherapeutic compounds commonly used to treat various cancers. Vinca alkaloids are one of the first microtubule-targeting agents to be produced and certified for the treatment of hematological and lymphatic neoplasms. Microtubule targeting agents like vincristine and vinblastine work by disrupting microtubule dynamics, causing mitotic arrest and cell death. The key issues facing vinca alkaloids applications include establishing an environment-friendly production technique based on microorganisms, as well as increasing bioavailability without causing harm to patient's health. The low yield of these vinca alkaloids from the plant and the difficulty of meeting their huge colossal demand around the globe prompted researchers to create a variety of approaches. Endophytes could thus be selected to produce beneficial secondary metabolites required for the biosynthesis of vinca alkaloids. This review covers the significant aspects of these vital drugs, from their discovery to the present day, in a concise manner. In addition, we emphasize the major hurdles that must be overcome in the coming years to improve vinca alkaloid's effectiveness.

Chitosan derivatives as surfactant carriers for enhanced oil recovery – Experimental and molecular dynamic evaluations of polymer-surfactant interactions

Surfactant injections in enhanced oil recovery (EOR) are very efficient, lowering the oil-water interfacial tension (IFT) and altering rocks wettability. Although efficient, surfactant injection during EOR process is economically unfeasible due to the high-cost caused by surfactant losses due to adsorption or precipitation on the rock surface. One strategy to reduce these losses during the flooding process is using surfactant carriers such as nanoparticles, emulsions, and polymers. Polymers are good candidates because they can act in transportation, alter rock wettability, and improve sweeping efficiency. Recently, the potential of chitosan derivatives as wettability modifiers of carbonate rocks was demonstrated. This way, using chitosan derivatives as surfactant carriers is an interesting strategy due to its high storage capacity and environment-friendly product. In this study, cationized (TMC) and hydrophobized (TMC-C14) chitosan derivatives were synthesized, characterized, and evaluated as OADA (oleic acid diethanolamide) surfactant carriers for EOR. Interfacial tension tests evaluated the potential of OADA in low and high salinity medium. Particle size measurements, done by dynamic light scattering, and molecular dynamics simulations (MD), allowed the understanding of the interaction between TMC or TMC-C14 and the surfactant. The controlled surfactant release at the water/oil interface by chitosan derivatives was evaluated by IFT measurements and MD simulations. The results showed that OADA is an excellent surfactant whose IFT reaches 10−2 mN/m, and chitosan derivatives were able to carry the surfactant to the site containing the oil. Thus, chitosan derivatives are an efficient supramolecular surfactant carrier system that can minimize surfactant losses by adsorption on the rock surface, being an interesting alternative for EOR application.

Obtaining non-digestible polysaccharides from distillers' grains of Chinese baijiu after extrusion with enhanced antioxidation capability

Distillers' grains of Chinese Baijiu (DGS) presents a significant challenge to the environmentally-friendly production of the brewing industry. This study utilized screw extrusion to modify the morphological and crystalline characteristics of DGS, resulting in a 316 % increase in the yield of non-digestible polysaccharides extraction. Physiochemical characteristics of extracted polysaccharides were variated, including infrared spectrum, monosaccharide composition, and molecular weight. Polysaccharides extracted from extruded DGS exhibited enhanced inhibitory capacity on α-amylase activity and starch hydrolyzation, as compared to those extracted from unextruded DGS. Additionally, the ABTS, DPPH, and OH radical scavenging efficiencies took a maximum increase of 1.20, 1.38, and 1.02-fold, correspondingly. Extrusion is a novel approach for the recycling non-digestible polysaccharides from DGS, augmenting the bioactivity of extracts and their potential application in functional food.

The influence of green finance availability to retailers on purchase intention: a consumer perspective with the moderating role of consciousness.

As the global warming crisis is increasing daily, it is crucial to find ways to reduce the carbon footprint generated by activities like the production, consumption, and distribution of goods and services. This empirical study has looked at one approach through which environment-friendly production and consumption can be encouraged. The developed model has studied the relationship between retailers' access to green finance and consumer purchase intention of green products by incorporating the role of environmental, status, and future consciousness. Theoretical foundations for this model have been taken from the theory of planned behaviour (TPB) and theory of reasoned action (TRA), which have extensively discussed the role of consciousness and societal norms while making purchase intentions. To gain insights about the purchasing behaviour of consumers, this study collected data from the Jiangsu province of China, where a non-probability convenience sampling technique was used to distribute a questionnaire to 400 respondents between February 2022 and August 2022. The collected data was analysed using Structural Equation Modeling (SEM) in SmartPLS in order to study the relationship between independent and dependent variables. Results of this study show that retailers' access to green finance positively impacts consumer purchase intention towards green products, and adding a consciousness perspective in the model strengthens this relationship. Moreover, the theory of planned behaviour and the theory of reasoned action were validated through this study, providing insights for policymakers on the importance of promoting green finance to influence green product purchase intention. Overall, this study shows that policymakers should give green financing to retailers and environmental and future awareness to consumers to encourage environment-friendly behaviour.

Organic Hazelnut Farming Techniques: A Review

Growing environmental and human health awareness due to increased concerns caused by intensive agriculture, has resulted a trend toward organic farming. Organic farming first started in the mid-1980s worldwide, introduced in Türkiye during 1989–1999 with raisin, fig and apricot, and then hazelnut was included in these products. In our country, total of 21.418,57 tons of organic hazelnut production occurs on 12.129,24 ha in 18 provinces. Considering the entire hazelnut production area, organic production is quite low. Organic hazelnut production requires daily monitoring of mechanical control and cultivation measures in the orchard. In addition to this intensive labor, the extraordinary increase in agricultural inputs in the recent period may explain such a low production amount. However, given the recent environmental disasters in the world, human and environmental friendly production systems such as organic agriculture should be encouraged in order to restore the natural balance that has been significantly damaged.

Modeling Environmentally Conscious Purchase Behavior: Examining the Role of Ethical Obligation and Green Self-Identity

Due to environmental degradation, using environment-friendly products has become necessary to reduce carbon emissions. However, the consumption of such products is still below expectations because these products are usually costlier than their traditional counterparts. The current study aims to investigate consumer behavior towards environment-friendly products using Ajzen’s theory of planned behavior as a theoretical model. The study seeks to examine the role of the key determinates of environmentally conscious purchase behavior, such as ethical obligation and green self-identity. A total of 386 responses were collected from consumers living in a few major cities of northern India using purposive sampling. The data were analyzed using structural equation modeling in Amos 22.0. The results demonstrated that attitudes towards environment-friendly products perceived behavioral control and green self-identity as the major determinants of green purchase intentions. In addition, attitude was reported to mediate the effect of ethical obligation on green purchase intentions and green self-identity was found to moderate the effect of attitude on green purchase intentions. Additionally, green self-identity was also reported to moderate the relationship between ethical obligation and attitude. The study adds value to the existing literature by signifying the role of green self-identity and ethical obligation in stimulating consumers’ green purchase intentions. The findings of the study are also meaningful for marketers and policymakers.

Fresh, mechanical, and durability properties of basalt fiber-reinforced concrete (BFRC): A review

Basalt fiber-reinforced concrete (BFRC) is relatively a new type of fiber-reinforced concrete, which has demonstrated good mechanical performance. Several types of fibers such as steel, glass, and carbon fibers, are used to improve the performance of plain concrete. However, basalt fibers (BF) are being considered superior to these because of their comparable mechanical strength, higher durability than glass fibers, lesser cost than carbon fibers, sustainability due to abundant raw material, and environment-friendly production process. Hence, the number of studies on BFRC are increasing over the years. This review paper covers the properties of BF and BFRC. The effects of BF length and dosage are discussed in detail in term of fresh, hardened, and durability properties of BFRC, followed by highlighting some areas for future research. It is concluded that BF can potentially replace the other conventional fibers which are being used in the industry.

Effect of Na and Al doping on ZnO nanoparticles for potential application in sunscreens.

This study investigated the environment-friendly production and characterization of zinc oxide nanoparticles (ZnO NPs) doped with sodium (Na) and aluminum (Al) metals to decrease the photocatalytic activity of ZnO for use in sunscreen. The metal-doped zinc oxide (ZnO) materials were prepared by the microwave method using extracts of Averrhoa carambola, also known as star fruit, as a reducing agent. The effects of metal-ion doping on the crystal structure, morphology, and optical characteristics of ZnO were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), and ultraviolet-visible (UV-Vis) spectroscopy. The sun protection factor (SPF) of the sunscreen formulations containing undoped ZnO, Na-doped ZnO (Na/ZnO), and Al-doped ZnO (Al/ZnO) NPs were found to be 10.10, 25.10, and 43.08, respectively. Therefore, Na/ZnO and Al/ZnO showed increased SPF. Additionally, the prepared nanomaterials and sunscreens were effective against Gram-positive and Gram-negative bacteria and showed antioxidant activities. The methylene blue (MB) degradation was used to evaluate the photocatalytic activities of the undoped ZnO, Na/ZnO, and Al/ZnO NPs, which were found to be 66%, 46%, and 38%, respectively. Therefore, due to the structural defects of ZnO NPs, their photocatalytic activity was decreased with Na- and Al- doping. Additionally, Al/ZnO is an ideal candidate as an ingredient in sunscreens.

An integrated biorefinery approach to obtain xylo-oligosaccharides from corncob using lactic acid-rich fermentation broth

Although xylo-oligosaccharides production from lignocelluloses via lactic acid hydrolysis is advantageous in terms of high yields with less by-products, the use of high purity lactic acid inevitably increases the cost of xylo-oligosaccharides production. The utilization of lactic acid-rich fermentation broth for xylo-oligosaccharides production can avoid the separation and purification of lactic acid. However, the feasibility of lactic acid-rich fermentation broth for xylo-oligosaccharides production from lignocelluloses was unclear. In this work, the results indicated that the highest xylo-oligosaccharides yield of 72% was obtained from corncob by lactic acid-rich fermentation broth pretreatment and xylanase hydrolysis. Subsequently, monosaccharides-rich hydrolysate (90.9 g/L) was obtained from solid residues of corncob by cellulase hydrolysis. Lactic acid-rich fermentation broth was produced by Weizmannia coagulans fermentation of the monosaccharide-rich hydrolysate. Besides, the obtained xylo-oligosaccharides and lactic acid mixture might be used as feed additives, avoiding the purification and separation of lactic acid or xylo-oligosaccharides. Meanwhile, the production cost of feed grade xylo-oligosaccharides from this work was much lower than the current market price. Overall, this work proposed a new strategy for efficient and environmental-friendly production of xylo-oligosaccharides from corncob.

Identification of Differential-Expressed Genes in Banana-Biostimulant Interaction Using Suppression Subtractive Hybridization

The use of environmental-friendly agricultural inputs to increase yield in crops could reduce environmental contamination and alleviate (a)biotic stress. In this study, we applied a foliar liquid biostimulant to banana plants, which was developed from the anaerobic fermentation of microorganisms with organic remains (manure and plant waste) and minerals to use as environmental-friendly product. To determine the effect of this biostimulant in the plants, a Suppression Subtractive Hybridization (SSH) library was developed from banana leaves in greenhouse conditions. Furthermore, salicylic and jasmonic pathways activation was evaluated by gene expression analysis. First, the application of the biostimulant to banana leaves increased the membrane stability index (MSI), which is directly related to a higher CO2 exchange and assimilation rate. Additionally, the total chlorophyll content increased in plants in comparison with the control plants. In addition, the SSH analysis revealed around 300 expressed sequence tags (ESTs). Several induced genes associated with different molecular pathways, including photosynthesis, anthocyanins production, and plant defense, among others, were encountered after bioinformatic analysis. Upregulated gene expression was demonstrated in different time points, after biostimulant application. Furthermore, induced expression of genes related to the jasmonic acid pathway was observed, which may prove beneficial to the plant under stress conditions.

Sustainable Supply Chain Management Practices in Ghana

The study assessed the sustainable supply chain management (SSCM) practices of 303 manufacturing firms in Ghana with an annual turnover of not less than $1,000,000, which were purposively selected for the study. A questionnaire comprising closed-ended questions was used to collect data on the SSCM practices of the firms, which were sustainable product design (SPD), sustainable process design (SP), supply-side collaboration (SSC) and demand-side collaboration (DSC). A weighted average index was used for the data analysis the results of which revealed that in manufacturing firms under study, SPD had a mean score of 4.44, SP had a mean score of 4.48, SSC had a mean score of 4.52 and DSC had a mean score of 4.52. The study identified many issues policymakers should look at to promote SSCM practices in manufacturing firms. In addition, policies should prioritise energy/material consumption; the reusing, recycling and recovering of materials; a standardised product design to facilitate reuse; environmentally-friendly materials, products and manufacturing processes; the easy disassembly of materials products; product life cycle analysis; and the formalisation of procedures for environmentally-friendly product design. Based on the diminishing of the world’s natural resources and the importance of SSCM, it is recommended that all manufacturing firms in Ghana and the world adopt SSCM practices. Moreover, manufacturing firms need to collaborate with their customers to anticipate and solve sustainability problems to achieve sustainability goals.

Determining factors in shaping the sustainable behavior of the generation Z consumer

Introduction: Organizations currently emphasize green marketing strategies by implementing marketing practices, aiming to design, produce, promote and sell green products. Thus, both consumers and producers have turned their attention to the category of environmental friendly products, taking into account that the concept of green marketing is now being given greater importance. Responsible organizations have begun to adapt their strategies in production, promotion and interaction activities with consumers or potential consumers of organic products in the context we are going through, when environmental protection becomes an imperative. Analysis of the sustainable behavior of Generation Z is a determining factor from the perspective of the task that this generation will naturally take on, in terms of environmental responsibility.Methods: The research aims to determine the profile of the Generation Z consumer, in order to adapt the strategic actions of the government or organizations to direct and educate as objectively and efficiently as possible towards adopting the principles of ecological, sustainable and responsible consumption. Based on the data collected through a survey, we analyzed the sustainable behavior of Generation Z consumers studying at Romanian universities where there are specializations in this field. The research is quantitative, using structural equation modelling with partial least squares (PLSSEM) to test the hypotheses regarding the relationship between the determining factors and the sustainable behavior of Generation Z consumers.Results and Discussion: The results show that there is a positive relationship between both the sustainable behavior of Generation Z consumers and the satisfaction it conveys to them, as well as their environmental protection activities. However, there is no relationship between the sustainable behavior of Generation Z consumers and the green marketing practices of the organizations, environmental issues and their identification with the environmentally responsible consumer.
