Impact of Pickering Emulsions Composition on Lipase Catalyzed Peroxyacetic Acid Synthesis

AbstractDue to the need for environmental protection and sustainability, there has been a rising need to replace the traditionally harsh oxidative functionalization process, which is essential for syntheses of various organic compounds, by biocatalysis. However, the investigated alternative processes are still challenged with enzyme instability and/or low specific reaction rate. Due to these still existing challenges and the recognition of Pickering emulsions as an efficient platform for continuous biphasic biocatalysis, the first, enzymatic step of the lipase catalyzed oxidative functionalization was investigated in bioactive Pickering emulsions. The study focused on the impact of Pickering emulsion composition such as the volume phase fraction, type and concentration of the nanoparticles and enzymes on continuous peroxyacetic acids synthesis. The type of nanoparticles used and Candida antarctica lipase B concentration significantly impacted the process while the other named parameters only had a marginal influence.

Enhancing local governments' environmental attention through open government data: evidence from China.

Environmental conservation has ascended to a prominent position on the global agenda, and China, recognizing the urgent need for environmental protection, has implemented nationwide measures. However, varying levels of environmental attentiveness among local governments have resulted in uneven implementation of these national directives across regions. Therefore, it is crucial to investigate the factors that drive local governments' environmental attention. Our study explores the impact of open government data (OGD) on local governments' environmental attention. Utilizing city-level data from 2010 to 2020, we employ a staggered difference-in-differences (DID) model for empirical analysis. The results reveal that OGD significantly and positively influences local governments' environmental attention. This influence is partly attributed to OGD's role in promoting government digitization, mitigating fiscal pressures, and increasing energy demand. Further analysis, including heterogeneity assessments, demonstrates that OGD has a more pronounced positive effect on environmental attention in cities with higher online political participation activity and a larger internet user base. Such empirical insights underscore the imperative for an integrative policy framework that accentuates the refinement of OGD platform in tandem with strategic enhancements in political participatory mechanisms and digital infrastructure investments, thereby fostering robust local environmental stewardship paradigms.

Process modelling of waste tyre pyrolysis for gas production using response surface methodology

The search for cleaner and renewable energy sources coupled with the need for environmental protection has necessitated the conversion of municipal solid wastes to energy sources. In this study, the pyrolysis of waste tyres in a fixed-bed reactor was carried out in a bid to generate non-condensable gases. The influence of process variables such as sample weight, reaction temperature, and reaction time were modelled and optimized using the central composite design of the response surface methodology. Based on the central composite design of the response surface methodology, the R2, adjusted R2 and predicted R2 values of 0.968, 0.941 and 0.750 respectively, indicated that the model properly fitted the experimental data. This implied the accuracy of the model prediction. The maximum predicted gas yield of 10.212 wt% was estimated under optimal conditions with desirability of 0.697, a dimensionless value indicating the closeness of the combination of input variables to the desired values for the response variables. The gases obtained upon pyrolysis of waste tyres can serve as a source of hydrocarbon gases in the petroleum and petrochemical industry.

Water Quality Assessment of The Three Lakes of Barandabhar Forest Corridor, Central Nepal

Addressing the global challenge of securing water for both human needs and ecosystem health is crucial. This study aims to characterize the physiochemical parameters of three lakes in the Bharandabhar forest corridor, Chitwan, Central Nepal: Tiger Lake, Kalimati Lake, and Rhino Lake. During the pre-monsoon season, four different sites (Eastern, Western, Northern, and Southern) of each lake were examined. To ensure precision, five replicated water samples were collected from each site, and standard protocols were applied to analyze various physiochemical parameters, such as pH, temperature, dissolved oxygen, free carbon dioxide, total hardness, chloride, total alkalinity, conductivity, nitrate, inorganic phosphorus, and total solid matter. Also, the Water Quality Index (WQI) was calculated. Results show that physiochemical parameter values mostly align with permissible limits according to regional and international guidelines. However, the mean phosphorous concentration and pH values of Tiger and Kalimati lakes exceed these limits. Rhino Lake displayed a mildly alkaline pH, while Kalimati and Tiger lakes exhibited slightly acidic characteristics. An interesting observation is the significant negative correlation between temperature and dissolved oxygen, indicating that as temperature rises, dissolved oxygen levels decrease. Additionally, WQI suggests that all three lakes maintain good water quality. However, a concerning finding is that all three lakes exhibited hyper-eutrophic conditions based on their phosphorous concentration. The lakes face significant threats due to high levels of organic pollutants and a rapid eutrophication process. Authorities must take significant actions to safeguard the lakes and ensure their future well-being. This research highlights the urgent need for environmental protection and conservation efforts to preserve the water quality and ecological balance of the Bharandabhar forest corridor lakes for the well-being of both human communities and the ecosystem.

A multi-objective energy efficiency optimization method of ship under different sea conditions

With the increasing need for environmental protection and the related advancement of relevant laws and regulations, ship energy efficiency optimization has become an important research topic. In this study, a multi-objective optimization model of ship energy efficiency based on the multi-objective particle swarm optimization algorithm is designed. The model uses the main engine speed as the optimization variable, and the ship's fuel consumption and sailing time as optimization objectives. Additionally, considering that the ship's sailing state can be affected by different sea conditions, the sea conditions are clustered by using the K-means clustering algorithm. Then, the route is divided, and the main engine speed is optimized for each segment. The results show that the solutions can reduce the fuel consumption by up to 25.28 % or the sailing time by up to 17.08 %. In the Ideal Solutions can reduce the fuel consumption by up to 3.98% or reduce the sailing time by up to 2.37%. Thus, the proposed model could effectively optimize the ship's energy efficiency. And it is necessary to consider the relationship between fuel consumption and sailing time when identifying the most suitable solution to meet real-world needs.

Changing consumer attitudes to make the Corporate Social Responsibility investment in sustainable fish production, a worthwhile investment to corporates

AbstractThe need for environmental protection, especially of depleting natural resources such as fish stocks, remains a global challenge. Global population growth increases food consumption. Some socially responsible corporate entities in the fish sector are producing and selling sustainable fish products, but beyond meeting their altruistic motives, they need consumers to respond favorably to these CSR initiatives to make the investments worthwhile and to encourage more organizations to invest in CSR for sustainable development. This paper reports the findings of research on the factors which influence consumers in the emerging market of South Africa, to respond favorably to sustainable fish product CSR initiatives. A causal research design and quantitative method was employed with a sample of consumers who were part of the South African LinkedIn community and who eat fish, whether concerned or not about sustainability. An online questionnaire was developed using an extension of the Theory of Planned Behavior. Univariate, regression and mediation analyses were carried out. Attitude towards sustainable fish products was found to be the only significant predictor of intention to purchase sustainable fish but it was also found to mediate the impact of health consciousness and environment concern. This paper thus focuses specifically on the role of attitudes in sustainable fish consumption in South Africa. Recommendations are provided for improving these consumer responses so as to make these CSR investments worthwhile to corporates and thus also positively impact fish sustainability.

A Combined Fuzzy AHP and GA Approach to Machine Scheduling Problems from an Environmental Perspective

With increasing concerns about the need for environmental protection and reduction of energy consumption, enterprises have to demonstrate their capabilities in lowering resource consumption by enhancing the efficiency of their systems. Although some approaches to quantifying the environmental burden generated by a product or service system such as life cycle assessment (LCA) and carbon auditing have been developed, expert judgments are often required to implement them. From an industry’s perspective, small- and medium-sized enterprises need an efficient tool to determine the best solution when considering various attributes simultaneously. Thus, a combination of fuzzy analytical hierarchy process and genetic algorithm has been introduced to solve scheduling problems and support the decision-making process. This study aims to effectuate the green scheduling on optimized machine-task assignments with fuzzy evaluation. The proposed approach is illustrated using a case example from a centralized dishwashing company. Results show that the global warming potential value can be reduced by 1.86% and the cost of operation is slightly increased by only 1.28%. The result of the proposed approach is presented simply in the form of machine-task assignments with optimized environmental impact values and associated costs. Therefore, no further result interpretation by environmental experts is required. This study can be a reference for government policymakers in formulating policies to synthesize operation optimization and business sustainability.

Environmental protection or economic growth? The effects of preferences for individual freedoms

Environmental protection is often seen in conflict with individual freedom and economic growth. The proponents of environmental protection suggest that the environment is a global resource that must be protected for future generations, even at the expense of economic growth and individual freedoms. The opponents claim that environmental protection should not come at the expense of individual rights and liberties, economic growth included. This paper studies the associations between public preferences for environmental protection, economic growth, and individual freedoms in eleven post-soviet countries on a representative dataset (N = 20006, age 18+, M ± SD: 46,04 ± 17,07; 58% women, 46,8% upper education). Methodologically we rely on correlations, principal component analysis, and ordinal regression analyses. The results suggest that preferences for most personal freedoms studied predict environmental protection and economic growth preferences. In addition, preferences for civil rights, rights for democracy, gender equality, income inequality, and the low role of the army in politics predicted higher preferences for environmental protection and economic growth. Interestingly, the government’s right to video surveillance in public areas, though diminishing personal freedoms in terms of anonymity, predicted higher preferences for environmental protection and economic growth. The importance of God in lives proved to increase preferences for environmental protection but was negatively related to preferences for economic growth. We suggest the government communicate the need for environmental protection as a part of the rights for individual freedom to live in a clean environment.

Impact of land use dynamics on land surface temperature using optical remote sensing data integrated with statistical analysis in Riyadh, Saudi Arabia

Changes in land use and cover (LULC) are now considered as a significant concern because they have a great impact on biodiversity loss and climate changes. Therefore, the present study was applied to assess the effect of land use dynamic on land surface temperature (LST). LULC maps of years; 1991, 2001, 2014, and 2022 were applied using Maximum likelihood classification MLC) while the LST was developed using thermal bands of Landsat images. LULC maps showed a considerable development and improvement in vegetation cover and urbanization. Results showed a negative and positive correlation between LST with NDVI and NDBI respectively. It was revealed that the estimated and predicted LST confirm the reliability of the present model with R2 = 0.95. The study calculated that the maximum LST in 2022 to simulate current state of Riyadh, Saudi Arabia and the results were 32.1, 45.5, 38.7 and 41.3 in winter, summer, autumn and spring respectively. We are now sounding the alarm because the state must act quickly and decisively to stop intensive forestation if it is to avoid very high temperatures by 2030. Our findings point to the need for environmental protection in response to the study area's quick conversion of LULC and increasing trend of LST.

EDUCAÇÃO AMBIENTAL E O USO SUSTENTÁVEL DA ÁGUA NA AMAZÔNIA: UMA ANÁLISE DAS PERCEPÇÕES AMBIENTAIS DE ALUNOS DO ENSINO FUNDAMENTAL II NA ESCOLA MUNICIPAL FRANCISCO GUEDES DE QUEIROZ SITUADA NA CIDADE DE MANAUS-AM/BRASIL

The process of industrialization and urbanization development has led to environmental degradation and a gradual decline in the quality of life of the world's population. In the Amazon, this process acquires fundamental importance, especially in the context of water resources in urban spaces and one of the most necessary actions to build water management mechanisms is educational action. In this sense, environmental education reflects the importance of assigning relevance to individual and collective participation in maintaining the natural cycle of life in all its construction and application dynamics. In this way, educational institutions have the responsibility to train and guide students and communities to better understand their cultural concepts and expand the meaning of actions in the context of environmental education practices. Considering this context, the theme selected for this research was the sustainable use of water, with the main objective of analyzing the environmental perceptions of elementary school students in Manaus, Amazonas, on this theme in the Amazon. The descriptive research had a qualitative-quantitative approach and was carried out through digital platforms with students from the Francisco Guedes de Queiroz Municipal School. The work developed comprised a total of 89 students from the 6th and 7th year and a smaller group with 5 students from the 6th year. A questionnaire was applied, with structured, objective and subjective questions, sent by the Google Forms platform to the cell phones of the students' guardians. The results showed that students' perception on the subject is still limited, but it already reflects a view on the need for environmental protection. Environmental Education activities are fundamental for the insertion of themes experienced by students in the construction of knowledge and citizenship. This theme emphasizes the current need for environmental education in a systematized environment, which arouses the interest of students, bringing benefits to society, and which aims to form a responsible citizen. Therefore, in order to carry out environmental education in everyday school life, teaching and learning must be based on real knowledge, on the experience and coexistence of students, and seek to develop critical awareness and skills in the school community.

Spent lithium manganate batteries for sustainable recycling: A review

Lithium-ion batteries (LIBs) account for the majority of energy storage devices due to their long service life, high energy density, environmentally friendly, and other characteristics. Although the cathode materials of LIB led by LiFePO4 (LFP), LiCoO2 (LCO), and LiNixCoyMn1-x-yO2 (NCM) occupy the majority of the market share at present, the demand of LiMn2O4 (LMO) cathode battery is also increasing year by year in recent years. With the rising price of various raw materials of LIBs and the need of environmental protection, the efficient recycling of spent LIBs has become a hot research topic. At present, the recycling of spent LIBs mainly focuses on LFP, LCO, and NCM batteries. However, with the continuous improvement of people’s safety of LIBs, LiMnxFe1-xPO4 (LMFP) batteries show better potential, which also improves the recycling value of LMO batteries. Therefore, this paper reviews current methods of spent LMO recovery, focusing on the characteristics of the recovery and separation process, which can serve as a reference for subsequent research on LMO recovery, increasing environmentally friendly recovery routes. Finally, the future development direction of LIBs recycling is prospected. Overall, this review is helpful to understand the current progress of LMO battery recycling.
