- Separation Technology of Components of Waste Pharmaceutical Blisters
Abstract: In this paper, the separation technology of components of waste pharmaceutical blisters and its adaptation to the industrial scale are described. It involved, among others, taking advantage of the phenomenon of difference in the density of the individual phases that were contained in the separation tank, i.e., the separating mixture, PVC plastics, and aluminium. As a result, the directions of movement of the separated blister components were opposite. All components of the separating mixture feature a similar surface tension (γ > 20 mN/m) which facilitates the penetration of the liquid between the blister component layers. After separation, the full-value products, i.e. polyvinyl chloride (PVC) and aluminium are obtained. The resulting products can be further processed and the entire technological process is a waste-free. PVC can be melted and processed into other products e.g. plastic components for the construction industry. Pure aluminium is a metal sought after and widely used in industry due to its low specific weight. An additional element supplementing the technology is the separation tank of our design in which the separation process of the blister components takes place. The advantage of the separation tank is that the separation process can be repeated many times with the same separating mixture until it is exhausted. Both separated blister components are directed to filtering followed by air drying without a mixing PVC plastic with aluminium.

- Determination of Cd, Pb and Zn in Polymers by Laser Ablation Microwave
Induced Plasma Optical Emission Spectrometry
Abstract: The potential of laser ablation microwave induced plasma optical emission spectrometry (LA-MIP OES) for the analysis of plastic materials has been investigated. Inorganic species, e.g., metals may be added to them as additives, anti-oxidising agents, stabilisers, plasticisers, colorants and catalytic residues, contaminants and may be present in a wide range of concentrations. The study revealed elevated content of trace elements (Cd, Pb and Zn) which are components of poly(vinyl chloride) (PVC) and polyethylene (PE). Laser ablation using wavelengths of 266 nm as a sampling method for MIP OES was used. The result achieved using elaborated system were compared with those obtained after polymer samples decomposition in high pressure-temperature focused microwave heating digestion system and standard sample pneumatic nebulisation (PN) to MIP OES spectrometer. The calibration strategy using cellulose pellets as support for qualitative analysis for element determination in polymers by LA-MIP OES was proposed. This analytical performance of the LA-MIP OES system was characterised by a determination of the limits of detection (LODs) and precision (RSDs) for elements tested. The experimental concentration detection limits for simultaneous determination, calculated as the concentration giving a signal equal to three times of the standard deviation of the blank (LOD, 3σblank criterion, peak height) were 2 µg g−1, 3 µg g−1 and 5 µg g−1 for Cd, Pb and Zn, respectively. The method offers relatively good precision (RSD ranged from 3 % to 5 %) for micro sampling analysis.

- Environmental Regulation, Environmental Policy Complexity and
Technological Innovation Efficiency
Abstract: Previous studies on the relationship between environmental regulation (ER) and technological innovation efficiency of defence industry (TIE-DI) mainly focus on variability and complexity, while few empirical studies have incorporated environmental flexibility into models, and most of them are based on questionnaires. Therefore, this paper takes environmental regulation and environmental policy complexity (EPC) as the entry point, so as to discuss the feasibility of improving the technological innovation efficiency of China’s defence industry enterprises (CDI), which aims to empirically test the mechanism of ER and EPC on improving the efficiency of applied technological innovation of China’s defence industry enterprises. The research conclusion provides sufficient theoretical basis and empirical support for strengthening the technical innovation efficiency support, standardising the market order and the market leading, establishing the information disclosure mechanism and improving the internal control of industrial enterprises.

- Carbon Emission Reduction Effect of Digital Infrastructure: From the
“Broadband China” Strategy
Abstract: The establishment of digital infrastructure embodies a pivotal instrument in propelling developmental metamorphosis, whilst fostering energy preservation and emission abatement. By employing municipal-level data spanning the period from 2009 to 2019, this research establishes a quasi-natural experiment anchored upon the “Broadband China” strategy. Employing the Difference-in-Differences (DID) methodology, this inquiry thoroughly examines the influence of digital infrastructure construction on the alleviation of carbon emissions. The findings indicate that the implementation of digital infrastructure exerts a notable impact on the reduction of carbon emissions. Moreover, carbon emission reduction resulting from digital infrastructure construction exhibits distinctive characteristics of heterogeneity. The empirical evidence presented within this study serves as a fundamental cornerstone for attaining the objectives of carbon peaking and carbon neutrality.

- Analysis of the Importance of Arts and Crafts in the Ecological
Environment Construction in the New Era
Abstract: For a long time, people tended to ignore the carrying capacity of the environment, resources, ecology and other natural systems, and also ignore the resource and environmental costs and natural costs incurred by economic growth, which eventually leads to the degradation of natural ecological environment and the decline of residents’ health. The results show that the pollution indexes of environmental art design range from 0.007 (comprehensiveness) to 0.912 (economic value), and those of ecological protection strategy range from 0.113 (industrial development) to 0.704 (innovative design); the carrying capacities of environmental art design range from 0.010 (space arrangement) to 0.684 (sustainability) and those of ecological protection strategy range from 0.124 (social value) to 0.938 (industrial development); the environment-protection factor of environmental art design range from 0.085 (sustainability) to 0.544 (land use) and those of ecological protection strategy range from 0.005 (aesthetic value) to 0.937 (concept presentation). Therefore, the arts and crafts in ecological environment construction in the new era can effectively and scientifically implement and carry out the landscape-site selection, material selection, land use, concept presentation, space planning, innovative design and so on under the guidance of ecological civilisation concept. The research results of this paper provide a reference for further research on the analysis of the importance of arts and crafts in the construction of an ecological environment in the new era.

- One Belt and One Road Impact on Environment, Economy & Health in Western
China Through Industry Transfer
Abstract: Based on fully absorbing and learning from the relevant research results at home and abroad, this paper focuses on four aspects: the transfer of polluting industries in the central and western regions and residents’ health problems. Firstly, the current pattern and development trend of regional pollution transfer in China; secondly, the economic effect of the transfer of polluting industries on the western undertaking areas; finally, from the micro and macro perspectives, the paper investigates the impact of the transfer of polluting industries on the individual health and health expenditure of residents in western China. The results show that the gap between industrial environmental and economic efficiency in the western region narrowed and gradually stabilised from 2008 to 2017. However, the gap between industrial environmental efficiency and economic efficiency in the western region widened from 2017 to 2020. The impact of environmental pollution on industrial environmental efficiency in the western provinces and regions has regional differences. Secondly, the present situation and trend of pollution control in western China are macroscopically investigated by comparing the output of general industrial solid waste and the investment in pollution control in different regions. Finally, this paper reveals the impact of the transfer of polluting industries on the health of residents in western China. Based on the characteristics of household category, age, and income of interviewees, the income growth effect of the transfer of polluting industries is less than the health loss caused by the transfer of pollution. It can be found that the transfer of polluting industries has a significant impact on the environment, economy, and the health of residents in western China.

- Outdoor Sports and Environmental Protection in Mountainous Areas Under
Ecological Civilisation
Abstract: Since the mid and late 19th century, people have paid more and more attention to the ecological environment, and environmental awareness and behaviour have been gradually strengthened. The global environmental protection movement is rising daily, and environmental protection will become the focus of human attention in the 21st century. Accelerate the establishment and improvement of the system and mechanism of land and space development, resource conservation and utilisation, and ecological preservation of the environment in the system of ecological civilisation, and promote the formation of a new pattern of harmonious development between man and nature and modernisation. Although China has formulated policies and regulations on environmental protection in outdoor sports development, environmental protection is grim due to problems such as insufficient government supervision, weak public awareness of environmental protection, and relatively backward environmental protection concepts and management methods. During the visit, outdoor sports lovers and club leaders were interviewed. In this context, with the continuous development of outdoor mountain sports driven by the improvement of people’s pursuit of life, there began to be contradictions between outdoor mountain sports and the ecological preservation of the environment, which also became the cause of the author’s concern and research.

- Research on Art Design of Urban Wetland Park Planning Based on the Concept
of Sustainable Development
Abstract: With the development of the social economy, the scale of cities has expanded rapidly, and the urban ecological imbalance has become increasingly severe, which has caused many urban problems. People gradually realise that cities and human beings develop more harmoniously and healthily by building and developing cities on the basis of natural ecology and seeking the harmonious coexistence of ecology and humanity. The results of the sustainable landscape ecological evaluation of Anhui Shilonghu National Wetland Park show that the park has good ecological, social, and economic benefits and functions. The urban ecological environment and social and economic development have a good supporting effect on the park, and its overall evaluation grade is good. Compared with other waterscape parks, the ecological function of urban wetland parks is the most basic and essential function of the landscape. It has multiple functions, such as popular science education and being close to nature and entertainment. Developing wetland ecological experience tourism activities benefits wetland protection and ecologically coordinated, sustainable development. It can also comprehensively improve wetland parks’ ecological, social, and economic benefits.

- The Spatial Ecological Environment Design of the Waterfront Public Areas
of Rural Rivers
Abstract: To revitalise established urban areas in the context of stock planning, the river surges in established urban areas play an irreplaceable role. In recent years, the water systems of rivers and surges in established urban areas of many international metropolises have undergone transformation and regeneration. The formerly hardened river banks have begun to be transformed into post-industrial places of integrated residence, leisure, and work, reshaping the ecological landscape and the functions of leisure activities of the rivers and urban spaces. By selecting typical representative cases for analysis and research, this paper determines the research angle and conducts a comparative study of waterfront open space in small and medium-sized cities and large cities from the perspectives of spatial layout, functional structure, ecological restoration, and artistic style, summarises the characteristics and current problems of waterfront open space in small and medium-sized cities at the present stage, and takes the problem as a guide, combining urban design, place theory and other theoretical studies as a guide. Planning and design strategy for waterfront open space in small and medium-sized cities is proposed. This paper selects representative waterfront open spaces and open waterfront spaces for field research. It uses the waterfront open space planning strategy proposed in the paper as a guide to provide a basis for waterfront open space planning and design and, at the same time, selects typical lots for optimal design to verify the implementation ability of the strategy. This paper digs into the rich historical, and geographical information contained in the sample villages in each area summarises the site selection characteristics of traditional villages in Hebei at the mesoscopic level between different areas and analyses the characteristics of the overall layout of villages dominated by natural factors such as mountains, hills and plains, and human factors such as ancient defile post roads, military defences, industries and temples. The spatial skeleton structure of the single-axis type, multi-axis type, organic network type, regular network type, and the fortress-wall enclosed village is extracted. The characteristics of its subtypes are summarised with sample cases. The elemental composition of village centres and boundaries is summarised.

- Design of Urban Sludge Emission Reduction Optimisation Strategy Based on
Fuzzy Neural Network
Abstract: Urban sewage sludge treatment is important for sustainable utilisation and virtuous cycle of freshwater resources. However, with the improvement of sewage discharge standards, ensuring stable operation of sewage sludge treatment plants is becoming an urgent problem to be solved in the sewage treatment industry. This paper proposes a FNN control framework based on different working conditions to optimise the whole process of municipal sewage sludge treatment and discharge. The framework first divides the working conditions according to the weather, forming a separate feature and an input vector together with the typical indicators of other sewage treatment plants. Then the FNN is used to complete the control and optimisation of various indicators, achieving the dual objectives of reducing energy consumption and optimising water quality. Finally, the model is tested for the tracking index of sewage flow. The results demonstrate that the FNN control method used has significantly lower MAE than the single method in the two indexes of energy consumption and water quality evaluation. This provides new ideas for the optimisation of urban sewage sludge treatment process in the future. Overall, the paper effectively highlights the importance of urban sewage sludge treatment and presents a well-designed FNN control framework for optimising the treatment process. Additionally, the paper could benefit from further elaboration on the significance of the results obtained, and suggestions for future research in this area.

- Financial Development and Environmental Pollution Control - An Analysis of
Intermediary Effect Based on Technological Innovation
Abstract: Based on the rapid development of green finance and the panel data of 30 provinces in China (excluding Tibet, Taiwan, Hong Kong and Macao) from 2007 to 2020, to deeply discuss the relationship between financial development (FD), technological innovation and environmental pollution (EP) control is the centre of this article by using panel fixed-effect and intermediary effect model. The influence of FD on EP is tested by building a benchmark regression model. In addition, the intermediary effect model is adopted to explore how FD affects EP control through technological innovation mechanism. The conclusions show that China’s FD can effectively promote regional EP control on the whole, and FD can improve EP through technological innovation mechanism, but there is significant regional heterogeneity: compared with high government intervention areas, FD can promote EP control through technological innovation in low government intervention areas. Therefore, it is suggested that all regions promote the construction of financial infrastructure, upgrade the level of regional financial marketisation, speed up the realisation of regional technological innovation and EP control. This work is conducive to the formulation of appropriate government policies to promote the improvement of the financial system and the establishment of innovative mechanisms, and the reasonable reduction of government intervention and the improvement of the efficiency of financial resource allocation based on the needs of financial market players.

- Evaluation of Soil Rocky Desertification in Karst Region Based on Deep
Belief Network
Abstract: Dynamic features from remote sensing photos may be successfully extracted using deep learning and symmetric network structure, which can then be used to direct them to carry out accurate classification. The DBN model can more effectively extract features from photos since it uses unsupervised learning. It can be reduced to the many symmetric Restricted Boltmann Machines (RBM) training problem. In this paper, a soil rocky desertification (RD) assessment model based on a deep belief network (DBN) is created in light of the complicated influencing aspects of Karst RD risk assessment encompassing several geographical elements. The model builds upon the conventional RBM framework and incorporates the influence layer of related elements as an auxiliary requirement for retrieving Geographic Information System (GIS) score data. Then, in order to forecast the level of soil rocky desertification, it learns the features of many elements. The experimental results show that the proposed model proposed in this paper has better prediction performance and faster convergence speed, and its classification results for different degrees of RD are more consistent with the actual risk assessment results.

- The Mechanism and Path of Finance Promoting the Development of Low Carbon
Economy
Abstract: Promoting the development of low-carbon economy (LCEco) to protect the environment is an important dimension to enhance national competitiveness and an effective path to achieve high-quality national development. Therefore, based on the endogenous LCEco growth theory, from the two dimensions of financial technology innovation (FTI) and financial product innovation (FPI), using the spatial measurement method of SLM and SEM, using the panel data of 30 provinces (municipalities and autonomous regions) from 2009 to 2021, this paper deeply explores the impact of FTI and FPI on the development of LCEco. The results show that: FTI and FPI have synergistic effect and positive spatial spillover effect on the LCEco, whose elastic coefficients for them are respectively (–0.125, p < 0.05; –0.084, p < 0.05). Different regions have obvious heterogeneous effects on the FTI, FPI and LCEco, whose elastic coefficients for them are (0.318, p < 0.05; 0.332, p < 0.05). The conclusion not only provides empirical support for the endogenous LCEco growth theory, but also provides effective evidence for the high-quality development path of China’s LCEco.

- An Empirical Study on Emissions Trading Influence for the Enterprise
Environmental Responsibility
Abstract: The primary objective of this paper is to address the inherent biases in the calculation of carbon emissions trading (CET) and foster the development of green innovation. By employing panel data from carbon emission trading pilots, the spatial Durbin model (SDID) is applied to assess the impact of CET on corporate environmental responsibility. By integrating CET and corporate environmental responsibility within a unified framework, this paper presents a novel analysis of the influence of environmental regulations on corporate environmental responsibility at the micro-level. Additionally, this study examines the spatial spillover effect of CET, thereby rectifying estimation biases. The model validation results indicate statistical significance below the 1 % level. The findings of this research reveal that it analyses the specific channels through which CET influences corporate environmental responsibility, providing insights that address the limitations of previous studies in mechanism analysis.

- The Influence of Ecoenvironment Factors on the Development of Skiing
Abstract: Skiing depends on the external environment, in which material, energy and information are frequently exchanged, and this external environment greatly affects the quality of skiing’s existence. In this article, an ecosystem assessment algorithm based on ANN (Artificial Neural Network) is put forward. Based on this, a skiing development model under the influence of ecosystem factors is constructed to explore the influence of ecosystem factors on skiing development. The simulation results show that after many iterations, the error of this method is better than that of the comparison algorithm in ecosystem analysis, with the error reduced by 28.17 % and the recall rate reaching 94.65 %, which is improved by 16.88 % compared with the comparison algorithm. Therefore, this model can provide theoretical support for studying the influence of ecological and environmental factors on the growth of skiing. Based on the analysis of the characteristics of the regional landscape ecosystem, the eco-environmental impact assessment of the ski resort project predicts the impact of project construction on the regional landscape ecosystem. It explores ways and means to maintain the ecological integrity of the natural system to carry out project construction on the premise of protecting the local ecosystem and building a natural and artificial composite landscape ecosystem with reasonable structure and high efficiency.

- Remote Sensing Detection and Resource Utilisation of Urban Sewage Sludge
Based on Mobile Edge Computing
Abstract: Improper disposal of municipal sewage sludge poses a significant threat to effective environmental protection. With the continuous advancement of artificial intelligence technology and the Internet of Things (IoT), remote sensing detection technology is emerging as a promising research avenue to address this issue. However, the current state of real-time detection technology is inadequate, hindering comprehensive and stable monitoring operation. Additionally, the rational use of network resources remains suboptimal. To address this challenge, this study proposes a resource optimisation technology for the current insufficient intelligent monitoring system of urban sewage sludge. By leveraging IoT and wireless technology, water meter data can be collected with minimal earth construction compared to traditional PLC collection. This is followed by utilising Faster R-CNN to plan the network transmission of sewage remote sensing information resources. Finally, the architecture collection module’s scalability is enhanced by incorporating edge computing and reserving sensor ports to meet future plant expansion demands. The experiment demonstrates the significant potential of this technology in application and resource optimisation. In actual parameter tracking tests, the proposed method effectively monitors sewage sludge, providing policy guidance and measure optimisation for relevant authorities, ultimately contributing to pollution-free urban development.

- Environmental Benefits of Green Buildings with BIM Technology
Abstract: Under accelerated urbanisation and rapid social and economic development, environmental pollution has become an important content of the construction industry. Therefore, the environmental benefit analysis of green buildings is of great significance to the effective use of energy and resources and to achieve the goal of protecting resources, reducing pollution and improving the ecological environment. The results show that the measured results of incremental environmental costs of the office building in Taiyuan City in land saving, energy saving, water saving, material saving, indoor environmental quality and operation management are decreased by 13.56 %, 11.02 %, 25.17 %, 14.43 %, and 15.25 %, respectively; incremental environmental benefits in land saving, energy saving, water saving, material saving, indoor environmental quality and operation management are increased by 23.15 %, 10.37 %, 19.30 %, 18.25 %, and 22.53 %, respectively. Those suggest that the BIM technology applied to the complete life cycle cost analysis of green buildings can test, measure and guide all the steps of building design, construction and maintenance and largely meet the criteria of resource-saving and energy-saving. The results of this paper provide a reference for further research on the environmental benefit analysis of green buildings based on BIM technology.

- Environmental Landscape Art Design Based on Visual Neural Network Model in
Rural Construction
Abstract: As the resources of social development continue to tilt to the countryside, the speed of rural construction continues to accelerate. In recent years, because of the higher quality of lifestyles, the demand of rural environment landscape art has gradually increased. In order to assist rural construction and improve the artistic quality of its environmental landscape, this paper proposes an environmental landscape art design method based on a visual neural network model. Firstly, the Swin Transformer text encoder is used to characterise the landscape art demand in rural construction. Then, the text feature vector of landscape art demand is input into the GAN model to generate the image content of rural construction. Finally, to better evaluate the landscape art level of the above methods in this paper, we propose an evaluating method for the landscape designing tasks. We conduct the experiments and achieve the FID value of 15.23, which can demonstrate that our method can effectively carry out an environmental landscape design for rural construction and simplify the process of rural construction. The landscape design evaluation method can evaluate the environmental landscape design accurately by the accuracy of over 80 %, and further improve and optimise the acceptance link of rural construction.
