A Study on the Efficiency of Green Technology Innovation in Listed Chinese Water Environment Treatment Companies

With the continuous advancement of the economy, the issues of resource scarcity and environmental damage are becoming increasingly severe. For example, in terms of water resources, the problems of environmental pollution and ecological imbalance in the water caused by industrial and agricultural wastewater are becoming more serious. In order to reduce water pollution, protect water resources, promote ecological balance, and reduce environmental risks, it is necessary to strengthen water environment management. This study uses the Malmquist DEA model to conduct a study on the green technology innovation efficiency (GTIE) of 24 water environment governance companies from 2019 to 2022. Corporate Research & Development investment and employee compensation are used as the input indicators, while the number of color patents obtained and operating income are employed as the output indicators. The evaluation criteria include pure technical efficiency, comprehensive technical efficiency, scale efficiency, and total factor productivity. The results show that there is significant room for improvement in the GTIE of the listed Chinese water environment governance enterprises, and there are considerable differences among different enterprises. The GTIE is significantly influenced by technological progress, the enterprise size, and the equity ratio. Therefore, water environment management enterprises should enhance their efforts in technological research and development and talent training, optimize resource allocation, improve the efficiency of green technology innovation, and effectively fulfill their social responsibilities. These measures will promote the efficient utilization of ecological water, the restoration of the water environment, and the establishment of a clean ecological environment.

Castor oil‐based paper packaging coating with water resistance and degradability obtained by thiol‐ene click reaction

AbstractWith the implementation of plastic restrictions and the increasingly serious problem of environmental pollution, paper with green and recyclable characteristics is gradually becoming a substitute for packaging materials. However, the rich cellulose structure in the paper, which contains hydroxyl groups leading to its hydrophilicity, allows water molecules to penetrate the paper and disrupt the hydrogen bonds between cellulose, resulting in a decrease in mechanical properties. Therefore, waterproof coatings are crucial for paper‐based materials to be used in many applications. Based on this, the paper surface was chemically modified with castor oil‐based resin (CO‐590) monomer prepared by coupling agent and castor oil (CO). The results indicated that the modified paper with the contact angle (CA) of 114° had excellent waterproof performance and had a reduction by 40.3% in water vapor transmission rate (WVTR), but also its mechanical increased to 26.9 MPa and the decomposition temperature to 410.5°C. In addition, the coating on its surface could be removed in an alkaline solution and had a possibility to recycle blank paper in the future for manufacturing sustainable production. This work not only provides a method for preparing modified packaging paper, but also expands the application fields of materials.

Possible ways of the sustainable development concept realisation by logistics companies, the necessity of using «green» technologies for decarbonisation of their business activity

Nowadays, more and more people are becoming seriously concerned about the problems of gradual environmental pollution and climate change. Over the past decades, they have become truly complex and global in scope. The long-term policy of ignoring these extremely important questions in the past has led to a staggering number of negative consequences that we are now seeing in all countries of the world. Today, it is no longer possible to continue to pretend that our activities have absolutely no impact on them. That is why, humanity is in constant search of new ideas that will be able to solve these problems, or at least slow down their pace. One of such, the most effective and promising examples was the creation of the extremely important concept of sustainable development. It has a very essential role in the spheres of logistics and management. Nowadays, all our activities in one way or another rely on them. In the global economy, the logistics sector is a major force that stimulates efficient trade and ensures the movement of goods. The logistics sphere works with a giant number of elements, various corporations, enterprises, companies, all possible transport vehicles and people. It connects them into a truly colossal in size and unified network. But it is always worth remembering that it has a huge impact on the above-mentioned problems. Currently, one of the key goals is to minimise the negative impact of logistics on the environment. That is why it is important to move this system in the direction of sustainable development, implementation of «green» initiatives, projects and technologies. In our time, the question of decarbonisation of logistics companies’ activities is really important and highly relevant, and therefore researchers should continue to monitor, study and analyse the prospects for the development of the logistics sector in this direction.

A Deep-Learning-Based Low-Cost Micro-Leakage Measurement System for Industrial Applications

Serious leakage will cause environmental pollution and safety problems, so strict leakage measurement is necessary for sealed products before leaving the factory. In this article, a semantic-segmentation-based micro-leakage measurement framework (MLMF) is proposed, and the core modules in MLMF are designed and analyzed. First, the DeepLabv3+ algorithm is improved from three aspects, including the design of the fusion layer, the introduction of the attention mechanism of the segmentation model, and the reconstruction of the loss function, which improve the precision of image segmentation tasks. Then, the volume of the intermediate cavity (ICV), which affects the accuracy of leakage measurement, is studied, and the reasonable selection interval of the ICV has been obtained. Finally, through the experimental analysis of the influencing factors of the bubble characteristics in the two-phase flow, the key parameters affecting the bubble shape are found, and the control of the initial shape, generation period, and oscillation process of the bubble is realized. The experimental analysis is carried out through the established experimental platform to verify the effectiveness of the proposed MLMF. The bubble method is innovatively combined with deep learning, and a series of problems, such as bubble shape control and liquid media selection, are solved. It provides a novel low-cost dry measurement mechanism for the field of micro-leakage measurement of sealed vessels.

가치-신념-규범(VBN) 모델에 기반한 밀키트 소비자의 친환경 의사결정과정 이해

With the significant growth of the meal kit market, environmental pollution problems caused by meal kit packaging materials are also emerging. Meal kit companies are pressured by society to use more eco-friendly packaging materials. However, doing so would only increase the production costs and sales prices, if consumers turn a blind eye to it. Therefore, for meal kit companies, it is necessary to understand the antecedents to consumers' eco-friendly behavior intentions and react accordingly. For this reason, this study used the VBN model to examine the decision-making process of meal kit consumers that leads from value beliefs and personal norms to eco-friendly behavioral intentions. In addition, the mediating roles of emotional factors (predicted guilt and pride) in the process were considered. To address the research objectives, a survey was conducted amongst adult men and women who purchased meal kits and plan to purchase them in the future. A total of 300 responses were collected from July 11 to 13, 2023. Among them, 249 (83.0%) suitable responses were analyzed. Descriptive statistics analysis and structural equation modeling analysis were performed using SPSS and AMOS programs. The analysis results are as follows. First, the values of meal kit consumers had significant effects on outcome perception, responsibility attribution, individual norms, and purchase intentions. Second, there were significant mediating effects of anticipated guilt and pride in the relationship between personal norms and the intentions to purchase eco-friendly meal kits. The analysis results emphasized the importance of values, beliefs, personal norms, and anticipated emotions in strengthening the eco-friendly behavioral intentions of meal kit consumers. It is suggested that meal kit companies should invest in monitoring and managing consumers' ecological values, personal norms, and emotional factors at the marketing level.

RELATIONSHIP OF LEAD WITH FREE RADICALS, REACTIVE OXYGEN SPECIES, OXIDATIVE STRESS AND ANTIOXIDANT ENZYMES

Heavy metals, which are high in the environment, are substances that have a high toxic effect even at low concentrations. Heavy metals taken into the organism through mouth, respiration and skin cannot be eliminated by the body's excretory pathways. In addition, since they have a durable structure, they participate in the food chain and accumulate in various body tissues. With the increase in industrial activities, heavy metal pollution has also emerged and has increased day by day. Lead is an element that is widely used in industry because it has a low melting temperature. However, it is known that lead, like other heavy metals, has an effect on problems such as environmental pollution and health problems. Occupational diseases such as lead poisoning occur as a result of direct exposure to lead. Direct exposure in this way can also cause death. Lead causes undesirable conditions such as increase of reactive oxygen species (ROS), emergence of oxidative stress and weakening of antioxidant system. Lead disrupts the prooxidant/antioxidant ratio. As a result, effects such as an increase in ROS and thus damage to the basic components of the cell such as lipid, protein and nucleic acid are observed.In particular, lead inhibits enzymes and prevents some enzymes from acting as antioxidants. As a result of exposure to lead, there is a decrease in the defense abilities of antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), glutathione (GSH) and ascorbic acid in blood and tissues. Lead increases lipid peroxidation and thus causes oxidative damage. Evaluation of the effect of lead at the cellular level is important in terms of developing solutions for the toxic effects of lead. In this study, the effect of lead on the cellular level in the organism and its effects on free radicals, ROS and oxidative stress were evaluated.

Photocatalytic activity of GaSSe/ WTe2 vdW heterstructure nanocatalyst: The first-principles study

Photocatalytic production of hydrogen provides a feasible strategy to solve the energy crisis and environmental pollution problems. In this paper, the bilayer Ga2SSe/WTe2 vdW heterstructure is proposed to be an effective photocatalyst for hydrolysis by first-principle calculations. Structural stability analyses show that the bilayer Ga2SSe/WTe2 vdW heterstructure is energetically and dynamically stable. The electronic properties show that the bilayer Ga2SSe/WTe2 vdW heterstructure belongs to an indirect bandgap semiconductor (1.287 eV), which is conducive to the reduction of the chance of carrier complexation. Photocatalytic performance analysis shows that the energy band edge positions of bilayer Ga2SSe/WTe2 vdW heterstructure are suitable for photocatalytic hydrolysis in the range of PH = 0 ∼ 14. In addition, the bilayer Ga2SSe/WTe2 vdW heterstructure has higher UV and visible light absorption, larger built-in electric field, and smaller carriers, which effectively ensures the effective separation of photogenerated carriers and their rapid migration to the reactive sites for the redox reaction of water. The results provide valuable theoretical guidance for the synthesis of bilayer Ga2SSe/WTe2 vdW heterstructure and its potential application as a hydrolysis photocatalyst.

The empirical results show that digital finance significantly increases firms' green investment, and this conclusion still holds after a series of robustness tests.

Study on Combustion Characteristics of Low Concentration Coalbed Methane Induced by Hydrogen Jet based on Excess Air Ratio

Low concentration coal bed gas used for power generation is a better treatment scheme at present, which solves the problem of environmental pollution caused by the direct emptying of coal bed gas. Coal bed methane is a methyl alkyl fuel, and slow combustion rate will cause abnormal combustion phenomena such as large combustion cycle changes. The initial ambient gas concentration has a great influence on the development and propagation of the flame. In this paper, a constant volume bomb model is established to change the excess air coefficient of methane air premix in the initial constant volume bomb, and the change law of combustion heat release is analyzed. The results show that when hydrogen participates in the combustion stage, the combustion rate increases with the increase of excess air coefficient. When hydrogen is burned out, the combustion rate decreases with the increase of excess air coefficient.

Air Quality Correlation Analysis Based on Apriori Algorithm

In recent years, air pollution has become an environmental issue of global concern. It not only affects human health, but also causes serious damage to the Earth's ecosystem. By analyzing the concentration values of various pollutants in the air and the air quality index (AQI) every hour, the most relevant components to the AQI can be identified. In this paper, Apriori association rule algorithm is applied to correlate various data in air quality monitoring to provide a new reference solution for solving environmental pollution problems in the future.

Molten salt synthesis of 1T/2H mixed phase MoS2 for boosting photocatalytic H2 evolution via Schottky junction under EY-sensitized system

Clean H2 fuel obtained from the photocatalytic water splitting to hydrogen reaction could efficiently alleviate current energy crisis and the concomitant environmental pollution problems. Therefore, it is desirable to search for a highly efficient photocatalytic system to decrease the energy barrier of water splitting reaction. Herein, the 1T/2H mixed phase MoS2 sample with Schottky junction between contact interfaces is developed through molten salt synthesis for photocatalytic hydrogen production under a dye-sensitized system (Eosin Y-TEOA-MoS2) driven by the visible light. In mixed phase MoS2 sample, the photogenerated electrons of 2H-phase MoS2 migrated to the 1T-phase MoS2 are difficult to jump back because of the existence of Schottky barrier, which greatly suppresses the quenching of EY and therefore results in an enhanced hydrogen evolution performance. Therefore, the optimized MoS2 sample (MoS2-350) has an initial hydrogen evolution rate of 213 μmol h−1 and corresponding apparent quantum yield of 36.1 % at 420 nm, far higher than those of pure Eosin Y. It is strongly confirmed by the steady‐state/time-resolved photoluminescence (PL) spectra and transient photocurrent response experiments. With the assistance of Density functional theory (DFT) calculation, the function of Schottky junction in photocatalytic hydrogen evolution reaction is well explained. In addition, a new and universal method (SVM curve) of judging oxidation or reduction quenching for photosensitizers is proposed.

Effects of Neolamarckia cadamba leaves extract on microbial community and antibiotic resistance genes in cecal contents and feces of broilers challenged with lipopolysaccharides.

The effects of Neolamarckia cadamba leaves extract (NCLE), with effective ingredients of flavonoids, on antibiotic resistance genes (ARGs) and relevant microorganisms in cecal contents and feces of broilers treated with or without lipopolysaccharide stimulation (LPS) were investigated. LPS stimulation increased (P < 0.05) the relative abundance of ARGs and mobile genetic elements (MGEs), such as tet(W/N/W), APH(3')-IIIa, ErmB, tet (44), ANT (6)-Ia, tet(O), tet (32), Vang_ACT_CHL, myrA, ANT (6)-Ib, IncQ1, tniB, and rep2 in cecal contents. However, the difference disappeared (P > 0.05) when NCLE was added at the same time. These differential ARGs and MGEs were mainly correlated (P < 0.01) with Clostridiales bacterium, Lachnospiraceae bacterium, and Candidatus Woodwardibium gallinarum. These species increased in LPS-stimulated broilers and decreased when NCLE was applied at the same time. In feces, LPS stimulation decreased (P < 0.05) the relative abundance of tet(Q), adeF, ErmF, Mef(En2), OXA-347, tet (40), npmA, tmrB, CfxA3, and ISCrsp1, while the LPS + NCLE treated group showed no significant effect (P > 0.05) on these ARGs. These differential ARGs and MGEs in feces were mainly correlated (P < 0.01) with Clostridiales bacterium, Pseudoflavonifractor sp. An184, Flavonifractor sp. An10, Ruminococcaceae bacterium, etc. These species increased in LPS-stimulated broilers and increased when NCLE was applied at the same time. In conclusion, LPS stimulation and NCLE influenced microbial communities and associated ARGs in both cecal contents and feces of broilers. NCLE alleviated the change of ARGs and MGEs in LPS-induced broilers by maintaining the microbial balance.IMPORTANCEAntibiotics showed a positive effect on gut health regulation and growth performance improvement in livestock breeding, but the antimicrobial resistance threat and environment pollution problem are increasingly severe with antibiotics abuse. As alternatives, plant extract containing bioactive substances are increasingly used to improve immunity and promote productivity. However, little is known about their effects on diversity and abundance of ARGs. Here, we investigated the effects of NCLE, with effective ingredients of flavonoids, on ARGs and relevant microorganisms in cecal contents and feces of broilers treated with or without lipopolysaccharide stimulation. We found that NCLE reduced the abundance of ARGs in cecal contents of lipopolysaccharide-induced broilers by maintaining the microbial balance. This study provides a comprehensive view of cecal and fecal microbial community, ARGs, and MGEs of broiler following LPS stimulation and NCLE treatment. It might be used to understand and control ARGs dissemination in livestock production.

Pengelolaan Daun Kering untuk Pupuk Kompos

A material given to plants to increase nutrient availability is called fertilizer. This research project aims to find a solution to the environmental pollution problem caused by the accumulation of dry leaf litter. Compost is made using dry leaf litter waste as the main component and EM4 as an aid. EM4 is responsible for breaking down the organic material in the leaves. The finished dry leaf compost is odorless, in the form of loose granules, has a brittle and somewhat rough texture, and is dark brown in color. The research method used is literature research, or research derived from books and print journals accessible on Google Scholar. This type of research uses descriptive studies and several works of researchers with relevant fields of study. Data collected through inductive methods are then analyzed using one or more initial data sets. The obtained data is examined using a descriptive analytical approach. By transforming dry leaves into more useful and economically valuable compost, this research also aims to develop and enhance the creative abilities of the community and the local economy. Bright colors indicate composting that is too dry or moisture levels below 30%. One determining factor of compost maturity is its aroma. The compost fermentation process will produce various strong aromas.

Utilization of ovalbumin and visible light irradiation for efficient and eco‐friendly production of AgNPs composite

Silver nanoparticles (AgNPs) are one of the most widely used antimicrobial agents. However, due to the potential problems of environmental pollution and high energy consumption, a green and efficient synthesis strategy of AgNPs is urgently required. Ovalbumin (OVA) is the most abundant protein in egg whites, and its extraction process is simple and productive. This paper reported a new green synthesis method of AgNPs by using OVA as an assistant accompanying with a visible light irradiation. Together with the reduction of silver ions, the uniformly dispersed OVA‐AgNPs nanocomposite could be formed within 30 min under xenon light irradiation by simple mixing AgNO3 and OVA in aqueous solution. The detailed mechanism study showed that tyrosine residue and peptide bonds in OVA played a major role in the reduction and stability of silver ions. In addition, in vitro antibacterial experiments indicated that 10 mg/L of OVA‐AgNPs, the minimum inhibitory concentration, has a good antimicrobial effect on both Gram‐positive and Gram‐negative bacteria, fungi, and some drug‐resistant bacteria species within 4 h of treatment, mainly due to the disruption of the structure of bacterial cell and the balance of reactive oxygen species. This work provides a new way for the green and efficient synthesis of AgNPs and shows good prospects for the applications in the field of biomedical materials and functional nanomaterials.

Environmental performance evaluation of electric enterprises during a power crisis: Evidence from DEA methods and AI prediction algorithms

With the continuous occurrence of power crisis events worldwide, meeting society's demand for electricity has kept coal-fired power generation high, which leads to a large amount of carbon dioxide emissions and environmental pollution problems. Therefore, improving the environmental performance of thermal power plants under the background of a power crisis has become particularly important. This research provides a new path for production optimization and environmental performance improvement of electric power enterprises from the perspective of combining prediction algorithms and DEA methods. We apply the modified non-radial directional distance function (MNDDF) method to a set of panel data containing 16 different cogeneration units and 27 different periods in eastern China and construct the grey prediction model to predict the future environmental performance of these units. Empirical analysis shows that our model has high prediction accuracy and offers a reasonable basis for future production decision-making adjustments for electric power enterprises. Based on the results herein, we present valuable suggestions for thermal power plants to improve their environmental performance during a power market crisis, including optimizing resource utilization, improving management level and operating conditions, strengthening technological innovation, and enhancing production factor allocation.

Under the Background of Economic Structure Optimization, Environmental Governance Promotes Macroeconomic Structural Adjustment Measures

Along with the implementation of reform and opening up in the 1970s, China’s economy entered a period of rapid development. During this period, the economic structure of our country has gradually changed from the primary industry to the secondary industry. Even today, the industrial industry still plays a very important role in the economic structure of our country. The industrial chain such as the real estate industry, chemical industry, and manufacturing industry is still the main industrial structure that promotes our economic growth for a long time. However, as the energy of industrial development is obtained by massive consumption of fossil fuels, the economic development brought by industrial development is behind the serious environmental pollution problem. We gradually realize that economic development cannot be based on environmental damage, but although our country has been committed to reversing the situation of environmental sacrifice for economic development at the beginning of the discovery of problems, the effect is very little. Therefore, how to maximize environmental protection under the current economic structure is the issue to be discussed in this paper. This paper mainly summarizes relevant experience through domestic and foreign literature, and clarifies the macro relationship between environmental governance and economic structure, and then discusses it from three dimensions: technological innovation, consumer demand, and international trade. The final results show that different types of environmental regulations have different effects on industrial structure, and the effectiveness of policy incentive regulation is about 23% higher than that of command control regulation. At the same time, according to the analysis results of economic structure upgrading in the Pearl River Delta region, the effect of environmental regulation on the regional industrial structure is also different, and the average effect can improve the overall industrial structure optimization rate by about 36%.

The Impact of Bad Urban Design on the City Environment

Over the past decades, there has been a growing interest in environmental issues realizing that humanity depends on the environment and that this environment has been constantly exposed to processes that could threaten the future of humanity. Cities emerged as the most important cause of pollution because they are the place where most industrial goods are produced and consumed. It was also found that a large percentage of the problems of environmental pollution was the result of the failure of the planning authorities in the implementation of the master plan originally laid out to control and control the city. We do not see a reaction from the residents of the region, despite the obvious problems in the study area, which include social and economic problems as well as environmental problems. On the contrary, many people want industrial activities to improve Value of their properties. The best way to solve urban areas' problems is at the planning stage

Heavy metal transport with adsorption for instantaneous and exponential attenuation of concentration

Heavy metal pollutant is a serious problem in environmental pollution, and it is very difficult to eradicate once it enters the soil. As heavy metal adsorption has been proven to occur, the heavy metal’s behaviour can be modeled as a transport equation with adsorption. Previous adsorption term mostly due to the concentration alone, while in here, the desorption effect given by the rate of change of the concentration is also included. Also, the heavy metals are frequently considered to enter the soil after being dumped into the soil for a certain period of time. But, quick dumping onto the soil can introduce heavy metal instantaneously. Heavy metals entering the soil through leaching or when their concentration in the soil is influenced by chemical reactions, can all lead to the exponential decay of heavy metals entering the soil. Based on two-dimensional advection diffusion equation (ADE) with the new adsorption term, analytical solutions are obtained for the cases of instantaneous and exponential attenuation of heavy metals emission to soil by the method of Laplace transform. The results highlight the significant influence of emission type on the peak concentrations. If heavy metals are instantaneously enter the soil, the peak occurs in the range of 1–3 m radius from the point of emission on the first day, while for exponential attenuation the peak occurs close to the point of emission. Furthermore, there exists a correlation between retardation factors and heavy metal concentrations, where a decrease in retardation factors leads to an increase in heavy metal concentration. It is essential to investigate both types of heavy metals emission to provide valuable information for proper pollution management, effective environmental regulations and enforcement.

Rapidly recyclable, monomer recovery and flame-retardant bio-based polyimine networks

With the development of a circular economy and sustainable environment, efficient and sustainable recycling of useful chemicals from thermosets is of great significance. However, most commercial thermosetting materials are difficult to reprocess, degrade, and recycle due to their permanent cross-linked network, and the preparation process consumes much fossil energy and causes serious environmental pollution problems. Furthermore, the high flammability makes them unsafe during service life and limits their applications. Herein, we used renewable lignin derivative vanillin as bio-based materials to synthesize a trialdehyde monomer (TMP) with phosphorus element and developed the bio-based polyimine dynamic networks with excellent comprehensive properties including outstanding reprocess ability, degradation recyclability, and fire resistance performance based on polyetherimide and 4-aminophenyl disulfide. The prepared bio-based polyimine materials with the dual dynamic networks (BPDNs) exhibited outstanding mechanical property with tensile strength of 61.6 MPa, super-rapid degradation rate and high monomer recovery rates of 70.5 %. The prepared BPDNs samples showed great flame retardancy with V0 rating and V1 rating in UL-94 vertical burning test and high LOI value of 29 %. Moreover, BPDNs could be reprocessed within 10 min at elevated temperatures (150 °C). This work provides a very effective method to prepare bio-based advanced thermosetting materials with multiple functions.

Strategy for the development of a new stick formula without microplastics

Plastic is a synthetic, malleable, and durable material that has been used for various applications since its invention in the late 19th century. During its very long-time degradation process, mechanical and/or photochemical processes fragment plastic into increasingly smaller fragments called microplastics (MPs). In the cosmetic field, MPs are directly added to many products for various functions, including to exploit their exfoliating and structuring power. Unfortunately, it has been realized that MPs are not retained in purification plants and therefore end up in the aquatic environment causing a high problem of environmental pollution. Polyethene (PE) is the most widely used MP in cosmetics due to its use as a structuring agent, to provide consistency to formulations and as a key ingredient in lipsticks and mascaras. Given the limitations imposed by regulations and the growing demand from consumers for chemical-free and eco-friendly products, the common synthetic and petroleum-based waxes used in lipstick formulations, such as PE, must necessarily be replaced by natural waxes of plant origin. In this paper we report the development of a chemical-free and eco-friendly cosmetic stick. To achieve the goal, it was necessary to study the compatibility of the ABWAX® Revowax, natural alternative to PE, with oils and colours to predict the behaviour of these structuring waxes in more complex systems. Through a systematic comparative study, the two waxes showed similar thermal characteristics and showed similar penetration curves, presenting overall comparable performance in the MP-free finished product. We can therefore consider ABWAX® Revowax natural wax a valid alternative to PE.
