In India, nearly 5 Mt of plastic waste is thrown out every year, averaging around 11 kg per person. Adopting circular economy could help India reduce its plastic waste problems. This study focuses on understanding the factors that affect people’s plastic purchasing and disposal behaviour. We applied Social Practice Theory to help understand people’s plastic waste management behaviour and the factors that affect what people do. Our findings suggest that the type of Material suitable for reducing plastic waste include infrastructure and services that deal with plastic waste segregation at the source, and tokens or money refund for waste returned to aggregators. Improving household Competence should rely on increasing knowledge around how to segregate, recycle, and return waste. For Meaning, messages need to aim at demonstrating social and environmental benefits of plastic waste reduction, and the positive aspects of waste segregation to remove this social stigma attached to waste handling.

Cold recycling technologies for asphalt pavements involve using emulsified asphalt binders (CCPREA) or foamed asphalt binders (CCPRFA) with cement additives. They have become increasingly popular for their environmental and resource conservation benefits. Despite the advantages, a comprehensive evaluation framework for these methods is needed. This study introduces an integrated analytical model combining the Analytic Hierarchy Process (AHP), Entropy Weight Method (EWM), and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) to assess the sustainability of both treatments across environmental, economic, and engineering dimensions. Life Cycle Assessment (LCA) results show that CCPREA has higher greenhouse gas emissions, energy consumption, and economic costs than CCPRFA. However, CCPREA demonstrates superior performance. The AHP-EWM-TOPSIS model scores CCPREA at 0.62, higher than CCPRFA's 0.38, in the multi-criteria evaluation.

The use of carbon fibers has expanded beyond aerospace to renewable energy and automotive sectors, driving demand for low-cost, eco-friendly alternatives to energy-intensive PAN-based production. This study Identified 28 Life cycle assessment (LCA) articles, encompassing 56 inventories for virgin and recycled carbon fibers. Following a screening process, 10 inventories representing distinct technologies were harmonized by aligning functional units, system boundaries, and background systems for meaningful comparison. Supercritical hydrolysis, a promising alternative, showed the lowest environmental impact, while energy-autonomous pyrolysis exhibited negative greenhouse gas emissions but produced fibers with 80 % of virgin tensile strength. This study represents the first attempt to harmonize LCAs of emerging technologies, addressing incomparability issues in published research to enable meaningful comparisons. It evaluates the reproducibility of LCA studies and offers recommendations for improvement. Additionally, it provides insights into the environmental impacts of emerging carbon fiber production and recycling technologies.

Waste photovoltaic (PV) wafers recovered from modules by physical crushing contain high levels of impurities and are unsuitable for reuse. This research demonstrates the successful regeneration of SiC (r-SiC) nanowires photocatalysts from these discarded PV wafers. The r-SiC exhibits enhanced photoactivity and reduces environmental emissions compared to market SiC, as evidenced by a life cycle assessment. By synthesizing Zn_xCd_1-xS/r-SiC (Z_xC_1-xSS) photocatalysts featuring a S-scheme heterojunction and internal electric field (IEF)-driven •OH production capability, we have not only repurposed waste but also achieved an unprecedented leap in photocatalytic efficiency. The resulting 20 %Zn_0.2Cd_0.8S/r-SiC (20Z_0.2C_0.8SS) photocatalyst exhibited a remarkable 96.67 % cefaclor (CEC) degradation efficiency under visible light within 30 min—outperforming r-SiC by 126-fold and Zn_0.2Cd_0.8S by 44-fold, and enabling efficient pharmaceutical wastewater degradation. This pioneering research not only turns waste into a valuable resource but also establishes a new benchmark in photocatalytic technology, providing profound insights into the mechanisms underpinning Z_xC_1-xSS photocatalysts.

Under the global trend of carbon peak and neutrality, the effectiveness of the carbon emission in construction industry remains unverified. This research investigates the impact of carbon emission policies on green innovation in the construction industry. Utilizing a multi-period Difference-in-Differences (DID) model, this study analyzes data on the quantity and quality of green innovation patents. Findings indicate that carbon peaking policies significantly enhance both the quality and quantity of green innovations, particularly in fossil fuel decarbonization and pollution control. The analysis reveals that the policy's short-term effects are stable and do not exhibit lagging impacts. This study provides a framework for assessing the influence of carbon emission policies on green innovation, aiding in the formulation of effective carbon emission strategies tailored to the industrial context.

Gravel roads are prone to severe distress, resulting in high construction and maintenance costs. Chemical stabilization is a widely used method for enhancing the durability of gravel roads. However, the environmental and economic impact of stabilized roads is still unknown. This study compared the environmental and economic impacts of 1-km-double lane gravel road stabilized with CaCl₂, MgCl_2, and concentrated liquid (LS) to an untreated road, using life cycle assessment (LCA) and life cycle cost analysis (LCCA). Results showed that stabilized roads had lower carbon footprint and cost than untreated roads. The LS reduced the carbon footprint of gravel roads by 3.6 % and 19.3 % than CaCl₂ and MgCl₂ stabilizers, respectively. However, LCCA results showed that the CaCl₂ stabilizer provided savings 17 % higher than LS and 15 % higher than MgCl₂. The findings of this study will help guide transportation agency's choices for gravel roads, leading to a lower environmental impact and cost.

Refuse-derived fuel plays a crucial role in waste-to-energy applications, offering a sustainable solution to mitigate global warming and waste management challenges. However, chlorine contamination in RDF poses significant industrial challenges, including severe boiler corrosion, unplanned downtime, and toxic gas emissions, highlighting the urgent need for efficient chlorine detection and removal. This study proposes a methodology combining near-infrared spectroscopy with deep learning architectures, including ResNet and CNN. A fuzzy labeling approach was implemented to enhance the adaptability of sorting to chlorine levels compared to binary classification. A dataset with 35 typical industrial solid wastes including textile, plastics and artificial leathers containing chlorine from 0 % to 34 % was built. Under simulated industrial conditions, the ResNet-based model achieved a classification accuracy of 87.6 % for new RDF materials. This advancement provides a reliable, scalable solution for detecting chlorine in diverse RDF scenarios, marking a substantial step forward in waste-to-energy processing and offering practical benefits to the industry.

This work investigates whether the Australian public still view plastics as a serious environmental issue and how perceptions of alternative materials may have shifted over time. Results were gathered through a survey of 1003 representative Australians. The results show that attitudes have remained constant, with some strengthening of original positions. This is made more noteworthy given the significant shifts in context that occurred during the five-year interval (including the COVID-19 pandemic). Plastics are still viewed as the key environmental concern and 85 % of respondents express a desire to reduce use of disposable plastics. All alternative materials are viewed positively, and 80 % percent of respondents agree they would like more of the plastic items they use to be biodegradable. This is despite understanding of biodegradable plastics decreasing. Combined, these results show policymakers that there is a high degree of public support for action on plastics and the development of alternative materials.

The food sector represents one of the largest contributors to global climate change, making it urgent for the public to transform their food consumption behavior. However, food consumption behaviors that can facilitate carbon reduction, and how to classify these behaviors from the perspective of behavioral science, have not been deeply explored. This study pioneers a novel categorization of carbon-mitigating food consumption behaviors based on an A-S-I framework (i.e., “Avoid” food loss and waste, “Shift” to low-carbon alternatives, and “Improve” dietary structure). Such a classification not only encompasses the full spectrum of emission-altering behaviors but also enables identification of common determinants across behavioral categories. Integrating existing behavioral theories and literature on the influencing factors of these behaviors, we systematically construct three models containing both constraints and motivating factors underpinning “A-S-I” behaviors. Our analysis reveals substantial variations in influencing factors across behavioral types. Notably, we found that factors such as face motivation, knowledge, and perceived behavioral control outweigh traditional psychological constructs (such as attitudes and norms) in predicting these behaviors among Chinese consumers. Based on these findings, we propose targeted measures to further enhance the feasibility of behavioral changes. These measures could effectively facilitate low-carbon dietary transformations, potentially generating dual benefits for climate change mitigation and food safety.

Operation optimization of Water Distribution Systems (WDSs) in large metropolitan areas is complex and time-consuming. Effective and reliable scheduling of WDSs can enhance the efficiency of urban water supply and ensure WDS resilience. This paper developed a historical discretization tensor-based optimization (HDTO) method from a new perspective, integrating experience of scheduling staff to sift the search solution space and guarantee the reliability and accessibility of scheduling. Results showed that HDTO method can achieve a 90.0 % reduction in running time relative to stochastic heuristic optimization and pruning method, while enhancing energy and hydraulic performance. Furthermore, the newly developed HDTO method demonstrated remarkable efficacy in optimizing the operation of 24-hour extended period operations, potentially contributing to real-time WDS control. Finally, through the application of emergency and managed scenario analyses, the HDTO method demonstrated significant improvements in both the social and economic sustainability of WDS.
