Analysis of the Influencing Factors of Enterprise Environmental Ethics on Enterprise Economic Performance

In the information age, people’s awareness of living environmental protection has increased unprecedentedly, and the concept of green environmental protection in enterprise economic behavior has been paid more and more attention by the market and consumers. The integration of green ideas, the improvement of production technology, and the research and development of environmental protection products have become the development trend of enterprises, and environmental ethical responsibility has also become an inevitable problem for enterprises. This paper analyzes the impact of enterprises’ conscious commitment to environmental ethics on their economic benefits, identifies the key influencing factors with the help of scientific statistical methods, analyzes the action mechanism of influencing factors in performance on the basis of the effect model and communication model, and analyzes the correlation between environmental ethics and economic benefits. The experimental results show that the long‐term dissemination of innovation and reputation factors in environmental ethics is conducive to the dissemination of green innovative technologies and products, obtaining the attention and recognition of more enterprises and stakeholders, broadening the scope of cooperation and sales, and obtaining the support of German consumers. Environmental ethics has a short‐term direct effect on performance. When the direct effect is reduced, the intermediary effect of innovation and reputation factors can achieve a positive effect on performance by transmitting benefits.

Research on Hotel Management Mode Based on Low-Carbon Tourism Concept

Nowadays, with the rapid development of China's economy, the living standard of the public is also gradually rising, but with the emergence of many ecological and environmental problems, more attention has been paid to it. Today, our country vigorously promotes and advocates ecological tourism and low-carbon tourism. This time, represented by hotel management, the concept of green environmental protection is effectively integrated into the hotel management mode, so as to better promote the effective transformation of relevant enterprises in green and low-carbon and better development in the future. Current practices in the actual application process, many hotels for low carbon service level, generally present a low level of coverage for some low carbon tourism culture and not many, in for a lot of hotel management personnel's quality above there are a lot of problems, these problems have seriously affected the hotel management to the transformation of low carbon line mode. Because of this, it is necessary to summarize the characteristics and importance of low-carbon tourism for the relevant hotel management departments. First of all, we can start to change the comprehensive quality of hotel management personnel and management system, so as to effectively improve the overall service level of hotel management under low-carbon tourism. In order to better achieve hotel management and low-carbon tourism synchronous development.

Determining the optimal airflow rate to minimize air pollution in tunnels

With the spreading of the green environmental protection concept, increasing attention has been paid to improving the tunneling environment. In this paper, the distribution characteristics of airflow fields, the diffusion laws of pollutants, and the influence of airflow rate changes on pollutants in tunnels under single-forced ventilation conditions were simulated according to the computational fluid dynamics (CFD) theory. In addition, the reliability of the simulation results was verified through field measurements. A three-stage distribution was observed once the dust concentration stabilized: we noticed areas with relatively low dust concentrations (<300 mg/m3), high dust concentrations (>500 mg/m3), and medium dust concentrations (~400 mg/m3, near the tunnel exit). Meanwhile, after stabilizing, the gas concentration was 0.67%. Properly increasing the airflow rate (Q) can effectively improve the tunnel environment: when Q reached 600 m3/min, the air in the tunnel was effectively purified. However, under a continuous increase of the airflow rate, there is a risk of pollution rebound.We conclude that, to effectively improve the tunnel environment and achieve a sustainable utilization of resources, the optimal operation airflow rate should be 600 m3/min.

Perm‐Inspired High‐Performance Soy Protein Isolate and Chicken Feather Keratin‐Based Wood Adhesive without External Crosslinker

AbstractCrosslinking modification can effectively improve the water resistance of soy protein isolate (SPI) adhesive, but it often depends on petroleum‐based reagents, violating the concept of green environmental protection. Here, inspired by the breaking and recombination of the disulfide bond in the perm process, a high‐performance wood adhesive is prepared by incorporation of SPI (modified by sodium sulfite to cleave the disulfide bonds of protein chains) and feather keratin (FK, extracted from waste chicken feathers by breaking the disulfide bond) without using any other crosslinkers. The crosslinking reaction occurs by disulfide bonds derived from the sulfhydryl group of FK and SPI. Thus the wet shear strength of the SPI/FK‐20 adhesive is improved from 0.57 to 1.18 MPa, an increment of 107%. This study provides a green strategy to prepare high‐performance protein‐based adhesive from the waste products‐chicken feathers, which will contribute to the development of the environmentally friendly wood adhesive industry.

Axial-Compression performance and finite element analysis of a Tubular Three-Dimensional-Woven Composite from a Meso-structural approach

The concept of green environmental protection is becoming increasingly important. This study used green high-performance basalt-fiber filament tows as raw materials to prepare tubular three-dimensional (3D)-woven preforms on a semi-automatic loom. Then, using the prepared preforms for reinforcement and resin as the matrix, a vacuum-assisted resin-transfer method was used to prepare tubular 3D-woven composites with three different internal diameters and layers. Axial-compression experiments were conducted to obtain the tubular 3D-woven composites' load-displacement curves and the energy-absorption capacities. The results reveal that both the inner diameter and the number of layers have significant effects on the composites’ axial-compression properties. As the inner diameter and layers increase, the peak load and energy absorption of tubular 3D-woven composites both have clearly increasing trends. Finally, a finite element analysis from a mesoscale approach was conducted to simulate the axial compression of the tubular 3D-woven composites in comparison with the experimental results. The analysis shows the initial damage, stress evolution, and final failure; it also reveals the stress concentration and failure mechanisms of the composites following the axial compression. Additionally, the preforms used as reinforcements withstand the main loads in the compression process. Finally, the stress-distribution analysis confirms a secondary role for the resin.

Runoff pollution control of a sewage discharge project based on green concept – a sewage runoff pollution control system

Abstract The problem of runoff pollution in sewage discharge projects mainly depends on manual inspections, and this traditional inspection method has high personnel and time costs. Moreover, with rapid development of the Internet of Things technology, application of intelligent information management has become a development trend of various neighborhoods where LoRa communication technology with low power consumption and long-distance transmission characteristics has been widely used. Therefore, starting from the concept of green environmental protection, LoRa technology is used in this paper to design and develop a runoff pollution control system including a management terminal, terminal and network components for waste-water discharge projects. The main function is to calculate and comprehensively analyze the conventional indexes such as CODCr, BOD5, ammonia nitrogen, and total phosphorus in the sewage treatment process, which reduces the calculation error of total pollutant treatment volume and total production volume, and improves the data accuracy of the sewage purification project. Meanwhile, the example verifies that the system proposed in the paper has accurate analysis of runoff pollution characteristics and accurate data calculation, which provides technical support for sustainable development and green development goals and mitigation of water crisis.

Discussion on the Reinforcement of Reinforced Concrete Slab Structures

Because of global environmental changes and the continued warming of the planet, the increase in carbon dioxide emissions has had a major impact on the environment. The development of zero-carbon buildings, the promotion of energy conservation and carbon reduction, and the concept of green environmental protection are regarded as important issues for humanity to achieve sustainable development. In Taiwan, the combination of moisture and high salt content in the environment, corrosion caused by chloride ions, and earthquakes often lead to the formation of crevices in buildings. These crevices can cause rebar oxidation and corrosion and even concrete structure damage or spalling. Conventional structural damages can be repaired with epoxy resin grout. However, such practices are incapable of removing the rusted components of the rebars inside the structures and thus subject the internal rebars to continuous oxidation in the original rust-covered environment. Components located deep within the structures would still swell as a result of continuous rebar oxidation and cause concrete breaking and spalling, making previous repair efforts ineffective. This study proposes an improved repair and retrofit technique that includes the removal of rust from oxidated rebar parts, by applying low viscosity epoxy resin to the slab base and allowing it to fully penetrate the concrete cracks and surface of the rebars inside, thus producing a protective layer and repairing the bond. Additionally, carbon-fiber reinforced plastic (CFRP) patches were adopted as repair materials and attached to the beams and slab (ceiling) surfaces. Angle steels were used at the edges and installed to connect the beams to the slab with chemical anchors. The gaps between the angle steels and the slab were filled with epoxy resin grouts. On the short side of the slab, small steel H-beams were installed 1 m apart as a means of retrofit. Because the epoxy resin expands by 8% after undergoing chemical reactions, it bonds perfectly with concrete, CFRP patches, and steel materials. Approximately 10 years have elapsed since the case-study was repaired using the proposed technique, and the retrofit effect has yielded excellent results to the present day, with no occurrence of internal swelling or spalling from rebar oxidation. The proposed retrofit technique can reduce construction costs, while ensuring effective repair and maintenance of structural safety, and extend the service life of structures.

Oriented tuning the photovoltaic properties of γ-RbGeX3 by strain-induced electron effective mass mutation

Based on the concept of green environmental protection, we hope to find a substitute for lead perovskites to reduce the pollution and achieve high photoelectric conversion efficiency. In this paper, the structural, electronic and optical properties of γ-RbGeX3 (X = Cl, Br and I) hybrid perovskites are investigated by density functional theory (DFT) calculations. The result shows that the γ-RbGeI3 has direct band gap of 1.38 eV and exhibits strong optical absorption in the visible light spectrum. However, the electron effective mass in the z direction is larger, which restricts the carrier mobility in the (0 0 1) direction. The blemish can be overcome by applying the −2% strain in the z direction, which causes the mutation of electron effective mass from 1.35 to 0.09 with little influence on the value of the band gap and the hole effective mass. These above findings also offer a new view to explore the inorganic perovskite for solar cell absorbers.

Carbon emission analysis of a residential building in China through life cycle assessment

In this paper, a quantitative life cycle model for carbon emission accounting was developed based on the life cycle assessment (LCA) theory. A residential building in Sino-Singapore Tianjin Eco-city (Tianjin, China) was selected as a sample, which had been constructed according to the concept of green environmental protection and sustainable development. In the scenario of this research, material production, construction, use and maintenance, and demolition phases were assessed by building carbon emission models. Results show that use and maintenance phase and material production phase are the most significant contributors to the life cycle carbon emissions of a building. We also analyzed some factor influences in LCA, including the thickness of the insulating layer and the length of building service life. The analysis suggest that thicker insulating layer does not necessarily produce less carbon emissions in the light of LCA, and if service life of a building increases, its carbon emissions during the whole life cycle will rise as well but its unit carbon emission will decrease inversely. Some advices on controlling carbon emissions from buildings are also provided.

Experiment Research on Activated Cement

Activated cement with the characters of low water demand and high activity was made with Portland cement clinker and dehydrate-gypsum and liquid superplasticizer which were used as grinding additive in the grinding process. Three states of grinding effect exist with correspondence of different dosages of super-plasticizer: the optimal grinding aid dosage, the critical dosage, and the supercritical dosage. First, under the condition of the optimal grinding effect, the activated cement had the maximum strength with little dosage of super-plasticizer and small effect on the performance of activated cement; second, within the critical dosage, the strength of activated cement was similar to the common cement, more super-plasticizer were held and the performance of cement was obviously improved; third, within the supercritical dosage, the strength of activated cement was reduced, but it can accommodate much super-plasticizer, and had a remarkable influence on the performance of cement. The experiment also shows that different properties of low water demand activated cement can be made with admixture of different concentrations of super-plasticizer. Within the allowed limit, use more admixtures was in compile with green environmental protection concept, improve the durability of concrete, and resolve the problem of compatibility between common cement and super-plasticizer, and offered technical support in the produce of commercial concrete by directly use of Portland cement clinker.
