Assessing the Impact of China’s Industry on Health: A Dynamic Three-Stage Bootstrap Model with an Endogenous Fuzzy Directional Distance Function

Evaluating the industrial eco-system is essential for promoting resource efficiency, environmental development, and public health protection. However, traditional Data Envelopment Analysis (DEA) methods are prone to biases and rely on precise numerical values, which pose significant challenges when evaluating the industrial ecosystem in China, particularly given the prevalent data uncertainties and environmental complexities. Additionally, DEA models are typically static, fail to capture the long-term trends and dynamic characteristics of the industrial ecosystem. To address these issues, this study proposes a dynamic three-stage model with an endogenous fuzzy directional distance function. The model integrates the generalized smooth bootstrap method and fuzzy comparison techniques to correct errors and account for data uncertainties, improving the accuracy and scientific validity of eco-efficiency assessments. Chinese enterprises face challenges such as excessive resource consumption, environmental pollution, and health risks, necessitating a more comprehensive and flexible evaluation system to adapt to the complex and dynamic nature of the industrial ecosystem. By focusing on industrial production, environmental governance, and health threats (IPEGHT) in China, the research aims to provide a robust framework for enhancing industrial eco-efficiency in a dynamic and uncertain environment. The results show: (1) The proposed method for selecting endogenous direction vectors is applied to the industrial production stage, thereby identifying the subsequent improvement directions for industrial production in various provinces. (2) The idea of integration is adopted to introduce the generalized smooth bootstrap method and fuzzy mathematics, to conduct a precise and comprehensive evaluation of the IPEGHT industrial eco-system. (3) From 2011 to 2021, China’s IPEGHT industrial eco-system efficiency showed a step-like distribution, and attention needs to be paid to environmental governance. The proposed method’ application can facilitate the integration of DEA and fuzzy mathematics, and fosters a more sustainable industrial eco-system.

Investigating the Synergistic Effect of Temperature and pH Dynamics on Biogas Yield from Lignocellulosic Biomass Codigested with Cow dung

The study investigated biogas production from control, pre-treated and blended waste samples, while also examining the interaction effects of ambient temperature (AT), slurry temperature (ST), and pH on the biogas volume generated from the waste samples. Experimental research design was adopted for the study. Nine biodigesters of 32L capacity labelled A-I, control (A-C), pre-treated (D-F) and blended (G-I) waste samples were used for the experiment. The digestion was carried out for a period of 35 days using the water displacement method in a laboratory scale bio-digester system. Data analysis was carried out using Excel, SPSS and STATA softwares. The methods used included descriptive statistics, multiple regression and Analysis of Variance (ANOVA). The pH and temperature readings for 35 days ranged from (6.5-8.4), AT (20-290C), ST (23-380C). Based on the study's results, there was a significant difference in the volume of biogas generated among the waste samples (F=6.4, SS=659.379, p=0.002, df=314). Specifically, significant differences were observed between the control and pre-treated samples (p=0.01) and between the control and blended samples (p=0.036). The effects of AT and ST (P=0.03) on the volume of biogas were not significant when analyzed individually; however, an interaction effect between AT and ST on biogas yield was observed. Also, pH, influenced the gas production significantly (F=3.954, p=0.021) likely due to its influence on microbial and enzymatic activity. The interaction effect showed that both temperature and pH had a combined effect on volume of biogas produced (p=0.003). These results underscore the importance of temperature and pH control in optimizing biogas production. Improved understanding of these factors could enhance anaerobic digestion processes, thus reducing greenhouse gas emissions, promoting resource efficiency and supporting circular economy principles.

The importance of women in 21st century rural Spain: Challenges and opportunities

The recent wave of urbanization has resulted in a significant increase in the number of people living in urban areas, surpassing those in rural areas. This concentration of people in cities promotes resource efficiency and economic growth. In Spain, 85% of the population live in urban (and peri-urban) areas, compared to 15% in rural areas. In recent times, the expression “España Vaciada” or “Empty Spain” has become popular to describe the depopulation problem in rural parts of the country. The objective of this qualitative study was to measure and analyze the opinions and perceptions that rural women have regarding the problems they are currently experiencing as well as their role as change agents in potentially promoting rural socio-economic resurgence both in the short and long term. We implemented a ten-question online survey using Google Forms from March 28th to May 13th, 2024. 216 women residing in towns and/or rural areas from 39 of the 50 provinces in Spain answered the survey. Most female interviewees affirmed that they played a very or fairly important role in rural areas, and most considered that their role would become more relevant in coming years. The depopulation problem was primarily caused by three main issues: a lack of employment, depopulation, and inadequate transportation. Although the role of women is a pillar for their communities, their numbers in rural Spain have been dwindling, and the territories have become, through time, more masculinized, thereby creating the imperative of creating socioeconomic opportunities for rural women to redress the resultant gender imbalance.

Towards Achieving Circular Economy in the Production of Silica from Rice Husk as a Sustainable Adsorbent

The growing concern over water pollution and waste management requires innovative solutions that promote resource efficiency within a circular economy. This study aims to utilize rice husk (RH) as a sustainable feedstock to develop highly porous silica particles and generate valuable by-products, addressing the dual challenges of waste reduction and water contamination. We hypothesize that optimizing the production of amorphous silica from acid-washed RH will enhance its adsorptive properties and facilitate the concurrent generation of bio-oil and syngas. Amorphous silica particles were extracted from acid-washed RH with a yield of 15 wt% using a combination of acid washing at 100 °C, pyrolysis at 500 °C, and calcination at 700 °C with controlled heating at 2 °C/min. The optimized material (RH2-SiO2), composed of small (60–200 nm) and large (50–200 µm) particles, had a specific surface area of 320 m2/g, with funnel-shaped pores with diameters from 17 nm to 4 nm and showed a maximum cadmium adsorption capacity of 407 mg Cd/g SiO2. Additionally, the pyrolysis process yielded CO-rich syngas and bio-oil with an elevated phenolic content, demonstrating a higher bio-oil yield and reduced gas production compared to untreated RH. Some limitations were identified, including the need for bio-oil upgrading, further research into the application of RH2-SiO2 for wastewater treatment, and the scaling-up of adsorbent production. Despite the challenges, these results contribute to the development of a promising adsorbent for water pollution control while enhancing the value of agricultural waste and moving closer to a circular economy model.

A Modified Johnson Cook Model-Based Kalman Filter Method to Determine the Hot Flow Behavior of Sustainable AA6082 Al Alloy.

AA6082 alloys play a significant role in advancing sustainable development goals (SDGs) by contributing to environmental sustainability, economic growth, and social well-being. These alloys are highly recyclable and align with SDG 12 by promoting resource efficiency and reducing waste. Their application in lightweight vehicles and improving energy efficiency in construction supports SDG 9 and SDG 11, as they help reduce carbon emissions and enhance the sustainability of urban environments. While AA6082 alloys offer significant advantages, their use has limitations that can hinder their industrial applications. One key challenge is their lower formability, particularly at room temperature. Elevated-temperature deformation is frequently employed to enhance the formability of these alloys and address their limitations. Thus, a deep understanding of the constitutive analysis of these alloys under a wide range of T and ε˙ is essential for manufacturing sound components from these alloys. Thus, this study aims to propose a new modification for the JC model (PJCM) and compare its reliability to predict the warm/hot flow behavior of AA6082 alloys with that of the original JC model (OJCM) and the modified JC model (LMJCM). By comparing the experimental results with these model results and confirming the determining correlation coefficient (R), average absolute relative error (AARE), and root mean square error (RMSE) values, it is concluded that the stresses predicted by the PMJCM closely match the experimental stresses of the LMJCM and OJCM because of the interaction between ε˙, ε, and T, which might be a reason for the complex nonlinear behavior of AA6082 alloys during hot deformation.

Advanced membrane contactor coupled with electrodialysis metathesis for efficient carbon dioxide capture and waste salt remediation

Rapid development of society has led to significant increases in carbon dioxide (CO2) emissions, primarily driven by intensified industrial activities and urbanization. Capture and utilization of CO2 not only mitigate greenhouse gas emissions but also support the transition towards a circular economy by recycling CO2 into high-value products. This study proposed a membrane contactor and electrodialysis metathesis (MC-EDM) for CO2 capture, NH4HCO3 generation, and NaHCO3 conversion. The MC facilitated the selective capture of CO2 from gas streams. Concurrently, EDM enhanced the NaHCO3/NH4Cl conversion from NH4HCO3/NaCl through selective ion transport mechanisms. The key influencing factors (e.g., gas flow rate, liquid flow rate, and ammonia concentration) for the MC process were optimized to achieve 1.014 mol/L NH4HCO3 concentration with 88.73 % yield and 78.94 % CO2 removal efficiency. Moreover, the parameters (e.g., solid-liquid ratio, membrane type, operating voltage, and salt component ratio) for the EDM process were optimized to achieve NaHCO3 with a 90.9 % yield and 97.80 % purity. Economic analysis indicated the overall process for NaHCO3 recovery was approximately 0.3267 $/kg. The cyclic experiments demonstrated the stability of MC-EDM for high-value NaHCO3 recovery. Thus, the MC-EDM pathways contribute significantly to reducing greenhouse gas emissions from industrial processes while promoting resource efficiency and economic sustainability.
