The growing environmental concern has promoted the global shift towards sustainable consumption, leading to the focus on reusable products. While extant literature has delved into the purchase intention of feminine hygiene products, it has often disregard the intentions behind women switching to reusable alternatives. To address this gap, the present research explores the drivers addressing women's intention to switch from disposable products to reusable options like menstrual cups and cloth pads. By utilizing non-probability purposive sampling, the study applies the Push, Pull, and Mooring (PPM) model to a sample of 386 women aged 18 to menopause. Theoretical insights from this research inform women's predisposition towards adopting reusable feminine hygiene products. Empirical findings identify pricing benefits as a significant pull factor along with women's positive attitude to switch. It also indicates that push factors have a lower impact on switching intention than pull and mooring factors. The findings underscore the potential for marketers to plan for a green transition by improving the design of sales strategy. This also provides a reference for the execution of government policies to promote the adoption of reusable feminine hygiene products to lower environmental wastage.

Based on the inefficient elimination of emerging contaminant perfluorooctanoic acid (PFOA) and the unpredictable performance of the filed-scale system, a novel in-situ iron-based and microbe-based sustained-release system and filed-scale model were developed to address the above issues in this study.
Especially, the PFOA-microbe-mineral interaction in various types of groundwater and the relevant mechanism were quantitatively and deeply studied. The results showed that the sustained-release interaction system in HCO3− type groundwater exhibited a greater retardation effect (Kd = 0.73 cm3 g−1) on PFOA compared to the interaction system under no ions condition (Kd = 0.49 cm3 g−1) or microbe system (Kd = 0.43 cm3 g−1). Moreover, the reaction rate λ of PFOA exhibited minimal fluctuation in HCO3− type groundwater, indicating lower competition from HCO3− ions for occupancy site and resulting in less PFOA repulsed to the lower reactive region (with lower Fe2+ and microorganism cells concentrations). Furthermore, the retardation effect for PFOA was boosted by secondary minerals-microbe interaction and joint adsorption. HCO3− facilitated the minerals-microbes interaction, leading to increased formation of β-FeOOH and improved retardation effect for PFOA. Additionally, the functional microorganisms Pseudomonas and Delftia were combined to drive the Fe3+/Fe2+ cycle and PFOA biochemical transformation. The two-dimensional spatiotemporal evolution simulation results showed that pollutant flux (transport risk) of PFOA in HCO3− type groundwater system (0.124 × 10−3 mg·(m2·s)−1) can be reduced by 23.0% compared to that in NO3− type groundwater system (0.161 × 10−3 mg·(m2·s)−1). This study quantitatively revealed the coupling effect of minerals, microbes, and ions on PFOA, contributing to optimizing the sustained-release system for effectively remediating different types of PFOA-contaminated groundwater.

The recovery of valuable chemical elements from industrial waste is essential for production processes' economic and environmental sustainability. The interaction between the iron ore tailings and sugarcane bagasse, both wastes, has the potential to provide a secondary iron source for future iron and steelmaking processes. This study evaluated the use of volatiles from sugarcane bagasse (SCB) and iron ore tailings (IOT) to the synergistic promotion of carbon deposition, H2 production and conversion of weak magnetic iron oxides in strong magnetic iron phases. The experiments were carried out at 400, 600, 800, and 1000 °C with different SCB/IOT ratios under an N2 atmosphere. In all tests, SCB and IOT were heated simultaneously in separate beds to prevent direct contact between the materials. The combination of 600 °C and higher SCB/IOT ratio resulted in a product with 96.7% magnetite, 98% magnetic fraction recovery, and 3.5% deposited carbon. The use of lower SCB/IOT ratio provided an increase in H2 production. Regardless of the mass ratio, heating the IOT and SCB simultaneously up to 1000 °C led to significant mineralogical transformations, reaching reduced phases such as wüstite, fayalite and metallic iron, which impaired magnetic separation efficiency. The results indicate an alternative for recovering iron from IOT using biomass waste as a renewable reducing agent for the steel industry.

The transition to a Circular Economy (CE) presents a paradigm shift, emphasizing sustainability, resource efficiency, and waste reduction. The existing literature extensively covers the principles and benefits of CE, but there is a notable gap in understanding how these practices are implemented at a local level. Specifically, there is a lack of detailed insights into the localized challenges, adaptation processes, and contextual factors influencing the adoption of circular practices. Additionally, the implications for different types of stakeholders and the effectiveness of localized strategies remain underexplored. By employing causal loop diagrams to depict system dynamics, interactions, and connections inherent in the transition to a CE, this research delves into the significance of understanding the complexities of circularity within a specific localized context. We draw qualitative data from semi-structured interviews and workshops with participants from key stakeholders within the textile and clothing sector in the Southwest of England. We find that legislation has a different impact on multinational corporations (MNCs) and small and medium-sized enterprises (SMEs) in their CE engagement. We also find that, while the flow of materials from MNCs to SMEs fosters regional innovation and knowledge-sharing, it does not always facilitate inter-organizational learning. Finally, both MNCs and SMEs recognize the CE’s potential for job creation, which highlights the need for more effective knowledge exchange strategies between businesses of different sizes. The study concludes that balancing CE principles with profit-driven pressures remains a significant challenge for both those founded on circular principles and those who are gradually incorporating CE principles into their organisation.

Immature manure contains extremely higher phytotoxicity, which impedes the maturity and safe utilization of compost in farmland. Composting technology can efficiently reduce phytotoxicity, germination index (GI) is an authoritative index of compost phytotoxicity. Consequently, livestock manure composting was conducted to investigate the impact of composting process on phytotoxicity and its consequential effects on seed germination inhibition. Results show that fresh manure disrupted radicle cell structure and antioxidants enzyme activities, activated endogenous phytohormones in radish seeds, ultimately resulting in failed germination. In comparison to the control group (seeds cultured in deionized water), seeds cultured in initial compost aqueous extracts exhibited 14,679 differentially expressed genes (DEGs) and 1091 differential abundance proteins (DAPs). However, after the thermophilic phase of composting (Day 7), the number of DEGs decreased by 83.40%, and DAPs decreased by 64% in cultivated seeds. Notably, over 70% of down regulated proteins in initial were found to recover after the 49-day composting, with the majority of these recovered proteomes enriched in ribosome and carbon metabolism pathways. Furthermore, fresh manure exerted fatal and irreversible inhibition on seed germination. However, after the thermophilic phase (7 days), the inhibition of seed germination transitioned from irreversible to reversible and recoverable. The results underscore the pivotal scientific significance of the thermophilic phase in the composting process, which is crucial for the safe and efficacious utilization of manure-based fertilizers in agricultural practices.

Many dietary guidelines are currently revised to consider environmental concerns. To inform these revisions, the aim of the present study was to describe the dietary factors that distinguish nutritious diets protective of the environment from nutritious diets that adversely affect the environment.
Individual self-selected diets from a representative sample of French adults were classified according to their nutritional quality (assessed through nutrient-based indicators) and their environmental impact (assessed through an indicator called the Product Environmental Footprint single score). Diets which combine the best nutritional quality and the best environmental impact constituted the Nut+Env+ class and were considered "more sustainable". Their dietary characteristics were compared to those of diets from the Nut+Env- class (i.e., the best nutritional quality but the worst environmental impact) and from the Nut-Env+ class (i.e., the best environmental impact but the worst nutritional quality). All of the analyses were based on 2000 kcal adjusted diets.
The two classes of diets with the best nutritional quality represented 5.5% (Nut+Env+) and 11.3% (Nut+Env-) of the sample, respectively. They were both in line with guidelines for a healthy diet regarding fruits and vegetables (more than 400g/2000 kcal) and dairy products (between 2 and 3 portions of dairy products/2000 kcal), as well as regarding sweet and salty food and beverages (low amounts). However, the “more sustainable” diets (Nut+Env+) had an environmental impact 46% lower on average than the Nut+Env- diets. The only statistically significant differences between those two classes of nutritious diets regarding their food contents were that the Nut+Env+ diets contained much less ruminant meat (7.4g vs 62.8g/2000 kcal), less seafood (30.0 vs 56.1g/2000 kcal) and more whole grains (42.9g vs 19.8g/2000 kcal), but also (slightly) more sweet and salty foods (107.9 vs 73.4g/2000 kcal) than the Nut+Env- diets. Diets from the Nut-Env+ class had the lowest environmental impact but their food content was in contradiction with dietary guidelines with, notably, low amounts of fruits and vegetables (236g/2000 kcal) and high amounts of sweet and salty food and beverages (317g/2000 kcal).
This study confirmed that nutritious diets are not necessarily environmentally friendly (and vice versa). Moreover, it showed that, among self-selected nutritious diets, only amounts of certain foods, in particular ruminant meat, seafoods and whole grains distinguish nutritious diets protective of the environment from nutritious diets that adversely affect the environment, suggesting that these foods should be particularly looked at when including environmental considerations in the revision of food-based dietary guidelines.

Decoupling carbon dioxide emissions from economic growth is crucial for China's dual carbon targets and sustainable development. Amidst the backdrop of a new development paradigm emphasizing domestic circulation, the decoupling analysis of embodied carbon emissions and embodied value added among Chinese regions is vital for green multiregional supply chain management to reduce carbon emissions while keeping economic growth. This study first comprehensively explores the decoupling status of carbon emissions and economic growth at the provincial level. Moreover, we focus on the embodied carbon emissions and value added across multiregional supply chains within China during 2012–2017 from both demand and supply perspectives. Results illustrate that the decoupling status of 22 provinces (e.g., Beijing, Shandong, and Xinjiang) displays diversity across different perspectives. Furthermore, the different multi-perspective decoupling statuses of critical sectors (e.g., the production and distribution of electric power and heat power sector) underscore the necessity for multi-side measures to reconcile carbon emission reduction with economic growth. Notably, this study identifies the decoupling status of most interregional pairs (i.e., two regions with carbon emissions and value added flows) are undesirable. It highlights the importance of interregional cooperation for decoupling embodied carbon emissions from value added growth along multiregional supply chains. Our findings can provide valuable insights for policymakers in advancing carbon emissions decoupling from economic expansion to achieve national sustainable development.

In light of the operational principles of Electrodialysis (ED), it is anticipated that this technology would significantly contribute to the recovery of waste acids through selective separation and subsequent proton concentration. However, the imperfect proton leakage characteristics of anion exchange membranes (AEMs) not only detrimentally affect the efficacy of ED-based acid recovery systems but also present considerable challenges for modeling endeavors. This study introduces a model based on the Nernst-Plank Equation at the cell pair scale, aimed at predicting ED performance. The model incorporates an empirical expression that links operational parameters, such as acid concentration and the concentration ratio between the concentrate and dilute compartments, to the permselectivities of AEMs in terms of anion transport numbers. Furthermore, both numerical and experimental analyses are performed to evaluate energy consumption across various operating conditions. The simulation outcomes derived from the proposed model exhibit a strong correlation with experimental data concerning acid transport (where the acid concentration increases from 0.25 M to 1.1 M through a two-stage concentration process), water migration (which demonstrates a nearly linear increase over time with applied currents, specifically a 15% increase under low-current conditions and a 100% increase under high-current conditions), and energy consumption. It is hoped that this model will aid in the design and optimization of ED-based acid reclamation processes, thereby enhancing their practical applications.
根据电渗析（ED）的运行原理，预计该技术将通过选择性分离和随后的质子浓缩，极大地促进废酸的回收。然而，阴离子交换膜（AEM）不完善的质子泄漏特性不仅会对基于电渗析的酸回收系统的功效产生不利影响，还会给建模工作带来巨大挑战。本研究介绍了一种基于细胞对规模的 Nernst-Plank 等式的模型，旨在预测 ED 的性能。该模型包含一个经验表达式，它将酸浓度、浓缩区和稀释区之间的浓度比等操作参数与阴离子传输数方面的 AEM 常选性联系起来。此外，还进行了数值和实验分析，以评估各种运行条件下的能耗。从所提出的模型中得出的模拟结果与有关酸输送（酸浓度通过两级浓缩过程从 0.25 M 增至 1.1 M）、水迁移（随着时间的推移与所应用的电流呈近乎线性的增长，特别是在低电流条件下增长 15%，而在高电流条件下增长 100%）和能耗方面的实验数据具有很强的相关性。希望该模型有助于设计和优化基于 ED 的酸再生工艺，从而提高其实际应用水平。

This study introduces a model based on the Nernst-Plank Equation at the cell pair scale, aimed at predicting ED performance. The model incorporates an empirical expression that links operational parameters, such as acid concentration and the concentration ratio between the concentrate and dilute compartments, to the permselectivities of AEMs in terms of anion transport numbers.

Cars are still used as the primary mode of transportation for daily commuting, with their emissions significantly affecting urban air quality, contributing to overall greenhouse gas emissions. Efforts to reduce car dependency have led to exploration of alternative transportation options such as cableway systems in urban areas. However, limited information exists regarding the environmental impacts and biodiversity implications of such systems. This study conducted a comparative life cycle assessment between a proposed cableway system for the city of Trieste, Italy and its current car transportation mode. The analysis considered both daily operational profiles and passenger occupancy rates of the cableway system. Drawing from similar cableway systems worldwide, it was calculated that the proposed Trieste cableway would accommodate 2007 daily passengers, on average. Results from the environmental assessment revealed that the cableway's operational phase had by far the greatest impact on all environmental categories, followed by its construction and by land clearance. Additionally, the use phase was found to be the major cause for most biodiversity loss, particularly towards terrestrial ecosystems. Comparisons of life cycle GHG emissions between the cableway and car transportation indicated that the cableway system would be a preferable option if the daily average passengers would reach at least 3,908, which is almost double than the expected ones. Furthermore, the cableway system exhibited larger environmental impacts across most categories compared to current car transportation. Thus, this study challenges the perception that the cableway system is a more sustainable option compared to conventional modes of transport, as additional factors need to be considered for a broader overview of the environmental performances.

How to encourage farmers to recycle pesticide packaging waste (PPW) is key to improving rural habitat. Previous literature has focused more on the role of policy interventions from a formal system perspective. Based on the perspective of combining informal and formal systems, this study empirically explores the impact of neighborhood effects and policy interventions on farmers’ PPW recycling behavior by using data from the China Rural Revitalization Survey (CRRS) and constructing an ordered probit model. The results show that neighborhood effects and policy interventions have a significant positive impact on farmers’ PPW recycling behavior, respectively, and the conclusion still holds after robustness test. In addition, neighborhood effects and policy interventions have substitution effects on farmers’ PPW recycling behavior. Finally, the heterogeneity analysis show that neighborhood effects generate significant incentive advantages for high-income farmers, elite farmers, and less-developed regions, whereas policy interventions are the opposite of it. Therefore, it is necessary to strengthen the construction of rural neighborhoods and implement policies that varied by people and regions, thereby improving farmers’ PPW recycling behaviors.
