Natural fiber–reinforced composites are attracting attention as sustainable alternatives to synthetic materials, but improving their strength, wear resistance, and water stability remains challenging. The present study focuses on developing silane-treated jute–sisal hybrid fiber-reinforced polyester composites enhanced with plant-derived cellulose microfillers to improve their mechanical, tribological, and hydrophobic performance. The main objective was to strengthen fiber–matrix interfacial bonding and enhance overall composite durability by combining hybrid natural fibers with chemical surface modification. The novelty of this work lies in the integration of silane surface treatment with cellulose microfiller reinforcement, which establishes strong Si–O–Si and Si–O–C bonds that improve adhesion, reduce voids, and minimize water diffusion—an approach not widely reported for hybrid natural fiber composites. The composites were fabricated by hand lay-up with cellulose contents of 0–6 wt%, followed by curing at 120 °C. Among all configurations, the G3 composite (4 wt% cellulose) exhibited the highest tensile strength (115.5 MPa), flexural strength (137.2 MPa), interlaminar shear strength (28.8 MPa), and impact energy (5.16 J), showing a 51 % improvement over the untreated system. The G4 composite (6 wt% cellulose) demonstrated the lowest wear rate (0.38 mm³ N⁻¹ m⁻¹) and coefficient of friction (0.014), while fracture toughness improved by 340 % and energy release rate by 224 % compared with neat polyester. Water absorption decreased to 23.2 %, indicating enhanced interfacial sealing and moisture resistance. The correlation between fiber hybridization, silane bonding, and filler dispersion confirms a strong synergistic effect. The developed composites offer a sustainable, high-strength, and wear-resistant material suitable for lightweight structural and tribological applications in automotive, aerospace, and defense sectors.

天然纤维增强复合材料作为合成材料的可持续替代品正引起人们的关注，但提高其强度、耐磨性和水稳定性仍然具有挑战性。本研究的重点是开发硅烷处理的黄麻杂化纤维增强聚酯复合材料，并用植物源性纤维素微填料增强，以改善其机械性能、摩擦学性能和疏水性。主要目的是通过将混合天然纤维与化学表面改性相结合，加强纤维-基体界面结合，提高复合材料的整体耐久性。这项工作的新颖之处在于硅烷表面处理与纤维素微填料增强的整合，它建立了强大的Si-O-Si和Si-O-C键，提高了附着力，减少了空隙，并最大限度地减少了水的扩散——这是一种未被广泛报道的混合天然纤维复合材料的方法。采用纤维素含量为0-6 wt%的手工铺层法制备复合材料，然后在120℃下固化。在所有配置中，G3复合材料（4 wt%纤维素）表现出最高的抗拉强度（115.5 MPa），抗弯强度（137.2 MPa），层间剪切强度（28.8 MPa）和冲击能（5.16 J），比未处理的体系提高了51%。与纯聚酯相比，G4复合材料（6 wt%纤维素）的磨损率（0.38 mm3 N−1 m−1）和摩擦系数（0.014）最低，断裂韧性提高340%，能量释放率提高224%。吸水率下降到23.2%，表明界面密封性和抗湿性增强。纤维杂化、硅烷键和填料分散之间的相关性证实了一种很强的协同效应。开发的复合材料提供了一种可持续的、高强度的、耐磨的材料，适用于汽车、航空航天和国防领域的轻量化结构和摩擦学应用。

Refractory materials are essential for sustaining high-temperature industrial processes, with the steel industry being the largest consumer. This study proposes a comprehensive life cycle assessment framework for refractories in the steel industry, addressing key methodological challenges, particularly those concerning various post-use refractory management strategies. Collecting inventory for refractory production is challenging due to confidentiality concerns and suppliers' reluctance to share information. To overcome this, an innovative method is developed to retrieve essential inventory data from the refractory's product definition. The framework is applied through a case study comparing two magnesia-carbon bricks used for steel ladle slag lining: one produced in China and the other in the Netherlands. Inventories for brick production are derived from the respective product definitions. Results reveal that the Netherlands brick performs better in climate change and acidification, while the Chinese brick shows lower impacts in other assessed categories. Electricity consumption during magnesia production and thermal energy demand for ladle heating are identified as the major environmental hotspots. Energy transition scenarios demonstrate the potential for significant improvements. Replacing national grid electricity and natural gas with renewable electricity and green hydrogen leads to more than 30 % reductions in most impact categories. Climate change impacts, for instance, decrease from 1.89 to 0.97 kg CO₂ eq for the Chinese brick and from 1.67 to 0.77 kg CO₂ eq for the Netherlands brick. Sensitivity analysis shows that magnesia production strongly influences environmental performance, while uncertainty associated with product-definition-derived data is generally minor.

耐火材料对于维持高温工业过程至关重要，钢铁工业是最大的消费者。本研究提出了钢铁行业耐火材料的全面生命周期评估框架，解决了关键的方法挑战，特别是那些涉及各种使用后耐火材料管理策略的挑战。由于保密问题和供应商不愿共享信息，收集耐火材料生产库存具有挑战性。为了克服这一点，开发了一种创新的方法，从耐火材料的产品定义中检索必要的库存数据。该框架通过对两种用于钢包渣衬的镁碳砖的案例研究进行了应用：一种是中国生产的，另一种是荷兰生产的。砖生产的库存来源于各自的产品定义。结果表明，荷兰砖在气候变化和酸化方面表现更好，而中国砖在其他评估类别中表现出较低的影响。氧化镁生产过程中的电力消耗和钢包加热的热能需求是主要的环境热点。能源转型情景展示了重大改进的潜力。用可再生电力和绿色氢取代国家电网的电力和天然气，在大多数影响类别中减少了30%以上。例如，中国砖对气候变化的影响从1.89千克二氧化碳当量减少到0.97千克二氧化碳当量，荷兰砖从1.67千克二氧化碳当量减少到0.77千克二氧化碳当量。敏感性分析表明，氧化镁生产对环境绩效影响很大，而与产品定义衍生数据相关的不确定性通常较小。

The European Union (EU) has implemented several strategies, including the zero-waste initiative, to minimize waste generation and enhance resource efficiency. Slovenia demonstrates this policy with the “Zero Waste Municipalities” project, which has shown notable success, but also highlights opportunities for further improvement. This study assesses the effectiveness of zero-waste initiatives and municipal solid waste management (MSWM) strategies across Slovenian municipalities using Material Flow Analysis (MFA) and Life Cycle Assessment (LCA). MFA results from eight municipalities indicate that biowaste (averaging 42.49 %) and paper (21.78 %) constitute the largest fractions of collected municipal waste. LCA results highlight that, on a per capita basis, environmental impacts in urban areas are generally lower than in rural areas for glass, wood, biowaste, and plastic waste streams, but higher for metal and paper. Scenario modelling for Ljubljana demonstrates that meeting the EU recycling targets for 2025 and 2030 would lead to substantial reductions in environmental impacts—especially in terms of Global Warming Potential (GWP) and Abiotic Depletion Potential (ADP). Specifically, achieving the 2030 targets could reduce CO₂ emissions from paper, plastic, and wood waste by 52 %, 25 %, and 77 %, respectively, compared to current baseline recycling ratios. The integration of MFA and LCA provides a comprehensive and quantitative assessment and insight into current waste management practices in Slovenian municipalities, accelerating a transition towards zero waste and circular municipalities. The findings offer valuable information for decision-makers, researchers and stakeholders aligning local waste management strategies with broader EU objectives.

欧洲联盟（欧盟）实施了若干战略，包括零废物倡议，以尽量减少废物产生和提高资源效率。斯洛文尼亚通过“零废物城市”项目证明了这一政策，该项目取得了显著成功，但也突出了进一步改进的机会。本研究利用物料流分析（MFA）和生命周期评估（LCA）评估了斯洛文尼亚各城市零废物倡议和城市固体废物管理（MSWM）战略的有效性。八个城市的MFA结果表明，生物废物（平均为42.49%）和纸张（21.78%）构成收集的城市废物的最大部分。LCA的结果强调，按人均计算，城市地区对玻璃、木材、生物废物和塑料废物流的环境影响一般低于农村地区，但对金属和纸张的影响较高。卢布尔雅那的情景模型表明，达到欧盟2025年和2030年的回收目标将大大减少对环境的影响，特别是在全球变暖潜能值（GWP）和非生物耗竭潜能值（ADP）方面。具体来说，与目前的基准回收率相比，实现2030年目标可以将纸张、塑料和木材废弃物的二氧化碳排放量分别减少52%、25%和77%。MFA和LCA的整合为斯洛文尼亚各城市目前的废物管理做法提供了全面和定量的评估和洞察，加速向零废物和循环城市过渡。这些发现为决策者、研究人员和利益相关者提供了有价值的信息，使当地的废物管理战略与更广泛的欧盟目标保持一致。

Ensuring transparency in textile production, particularly in addressing environmental and social issues, has driven the development of technologies such as smart tags, encrypted labels, blockchain, and fibre DNA. However, full traceability from raw material extraction to the finished product remains a challenge, especially due to chemically aggressive processes like dyeing and washing. This study adopted a case study approach to evaluate a yarn tracking technology that embeds a code directly into the textile product, remaining functional throughout its life cycle. The assessment combined technical tests, payback-based economic analysis, and environmental evaluation using the Mass Intensity Total (MIT) metric. Conducted in a Brazilian textile company, the study validated the coding system's durability and feasibility. The code remained readable after industrial processing, enabling traceability across all process stages. Results revealed annual cost saving of USD 5639.00 and a payback period of approximately 5.4 years. The implementation also led to a reduction of 8.5 million kilograms in MIT, indicating substantial environmental benefits. The system facilitates the identification of leftover fabric cuts, supporting waste reduction and material conservation. Additionally, by geolocating production steps, it helps monitor working conditions and mitigate risks of labour analogous to slavery. By ensuring durable, embedded traceability, this research advances biopolymer tracking and contributes to more transparent, circular, and socially responsible practices in the textile sector. The adoption of this technology may assist companies in aligning operations with transparency goals, legal compliance, and sustainability standards.

确保纺织品生产的透明度，特别是在解决环境和社会问题方面，推动了智能标签、加密标签、区块链和纤维DNA等技术的发展。然而，从原材料提取到成品的完全可追溯性仍然是一个挑战，特别是由于染色和洗涤等化学侵蚀性过程。本研究采用案例研究的方法来评估纱线跟踪技术，该技术将代码直接嵌入纺织品中，并在其整个生命周期中保持功能。评估结合了技术测试、基于回报的经济分析和使用质量强度总（MIT）指标的环境评估。该研究在巴西一家纺织公司进行，验证了编码系统的耐用性和可行性。在工业处理之后，代码仍然是可读的，支持跨所有过程阶段的可追溯性。结果显示，每年可节省成本5639.00美元，投资回收期约为5.4年。该项目的实施还使麻省理工学院的温室气体排放量减少了850万公斤，表明了巨大的环境效益。该系统有助于识别剩余的织物切割，支持减少浪费和节约材料。此外，通过对生产步骤进行地理定位，它有助于监测工作条件，减轻类似奴隶制的劳动风险。通过确保耐用，嵌入式可追溯性，这项研究推进了生物聚合物跟踪，并有助于纺织行业更加透明，循环和社会责任的实践。采用该技术可以帮助公司将操作与透明度目标、法律遵从性和可持续性标准相一致。

This study focuses on the recovery of rare earth elements (REEs) from acid mine water (AMW) through a two-step selective process, which consists of a selective extraction with ion exchange followed by a precipitation stage using oxalic acid. Optimization of the effective REE recovery from sulphuric ion-exchange concentrates results in sustainable AMW management, providing a secondary resource for critical metals towards green transition. Experimental results indicate that (1) the use of oxalic acid facilitates the formation of REE-oxalate crystals, yielding recovery efficiencies in light rare earth elements (LREEs) much higher than for heavy rare earth elements (HREEs) at specific excess doses, and that (2) LREEs act as precursors for HREE precipitation. Moreover, REE-oxalate crystallization depends on the oxalic acid dose, pH, and precipitation time (PT). The longer the PT, the larger the crystals, which are economically advantageous. The study highlights that AMW is a potential secondary source for the REE recovery, which contributes to sustainable mining practices and provides confidence for further optimization of REE recovery processes.

The increasing demand for circular economy solutions in plastic waste management has emphasised the need for quality assurance and traceability in recycling systems. However, the extent to which businesses adopt and prioritise these factors remains unclear, particularly in the Australian context. This study examines how businesses in the Australian plastic recycling sector perceive and implement quality control practices. It aims to identify key barriers and enablers influencing the adoption and assess the role of these elements in promoting circularity. A national, ethically approved survey was conducted among 65 Australian businesses involved in the plastics value chain. Respondents were segmented based on company size and the presence or absence of a CE strategy. The study's analytical model was statistically validated using t-tests and effect-size analyses to ensure internal consistency. Companies with a CE strategy emphasise quality control, certification standards, and traceability more than those without. The most cited barriers to quality adoption include cost, market demand, and regulatory gaps, while traceability systems remain underutilised despite their recognised importance. Due to resource constraints, small and medium-sized enterprises report greater difficulties in adopting standardised quality practices. The study highlights a critical gap in integrating traceability and quality assurance into Australian recycling systems. By combining a validated analytical model with authenticated survey data, the study provides reliable evidence that regulatory enforcement, financial incentives, and harmonised standards are essential to improve material reliability and advance circular economy outcomes in Australia.

塑料废物管理对循环经济解决方案的需求日益增长，强调了回收系统中质量保证和可追溯性的必要性。然而，企业采用和优先考虑这些因素的程度仍不清楚，特别是在澳大利亚的情况下。本研究考察了澳大利亚塑料回收部门的企业如何认识和实施质量控制实践。它旨在确定影响采用的主要障碍和推动因素，并评估这些因素在促进循环方面的作用。在参与塑料价值链的65家澳大利亚企业中进行了一项全国性的、经道德批准的调查。受访者是根据公司规模和是否存在CE战略进行细分的。本研究的分析模型采用t检验和效应量分析进行统计验证，以确保内部一致性。有CE战略的公司比没有CE战略的公司更强调质量控制、认证标准和可追溯性。被引用最多的采用高质量的障碍包括成本、市场需求和监管缺口，而可追溯系统尽管重要性得到认可，但仍未得到充分利用。由于资源限制，中小型企业报告在采用标准化质量实践方面遇到更大的困难。该研究强调了在将可追溯性和质量保证纳入澳大利亚回收系统方面的关键差距。通过将经过验证的分析模型与经过验证的调查数据相结合，该研究提供了可靠的证据，证明监管执法、财政激励和协调标准对于提高材料可靠性和推进澳大利亚的循环经济成果至关重要。

The large-scale integration of renewable energy sources requires advanced control systems capable of maintaining grid stability and improving energy efficiency under dynamic operating conditions. This study presents the design and experimental validation of a Hybrid Energy Management System for residential microgrids that combines short-term forecasting, Mixed Integer Linear Programming optimization, and real-time control within a unified architecture. The proposed system is implemented and validated through Power Hardware in the Loop testing on a 300 kVA experimental platform at the Smart Grids Test Lab in Ben Guerir, Morocco, using photovoltaic, battery, grid, and load emulators. The forecasting layer generates day-ahead load prediction using multiple algorithms. The Linear Regression model achieves the best accuracy with an R2 of 0.960 and an RMSE of 0.145 kW, while the Random Forest model achieves an R2 of 0.949 and an RMSE of 0.136 kW. Stress and robustness analyses demonstrate that the EMS maintains cost variations below 2 % for forecast deviations of ±10 %. The hybrid control approach achieves an overall cost reduction exceeding 50 percent across multiple scenarios compared with the unoptimized baseline, while maintaining stable real-time performance with an average PLC execution cycle of 120 ms and a maximum response delay below 150 ms. Environmental assessment indicates a 30 to 35 percent decrease in CO₂ emissions, equivalent to approximately 12.7–44.7 kg of CO₂ saved per day, depending on solar conditions. In addition, the system ensures high user comfort by achieving more than 90 % task completion for flexible loads within preferred time windows while preserving continuous power for critical ones. These results demonstrate that the proposed framework is robust, scalable, and experimentally verified for intelligent microgrid control, bridging the gap between simulation-based energy management strategies and real-world implementation with potential applicability to both residential and industrial energy systems.

Manufacturing companies often adopt the product family approach to offer a wide range of products efficiently and cost-effectively. With the growing emphasis on the sustainability and circularity of product families, extensive research has evaluated these aspects in recent decades. Building upon this existing research, this study aims to identify the most prevalent indicators and methodologies employed for their assessments. A systematic literature review yielded 40 relevant articles. The results reveal that existing indicators and methodologies are often data-intensive and resource-consuming, making the assessment of the sustainability and circularity of product families a complicated and extensive process. Findings also show that only four circularity strategies (i.e., remanufacture, reuse, recycle, and refurbish) were investigated for product families. Furthermore, most circularity indicators considered in these assessments are strategy-specific, and no generic indicators exist for a holistic assessment of circularity for product families. Moreover, most studies focus solely on carbon footprint assessment, overlooking other impact categories. Additionally, the social aspect was scarcely investigated in literature for product families. Finally, most of the reviewed studies evaluated the sustainability and circularity of product families within electric and electronic equipment. Based on these findings, this work underlines the need for more efficient methodologies and indicators, while establishing relationships among economic, environmental, social, and circularity dimensions to support the development of sustainable and circular product families. It is also strongly recommended to assess the impact of additional circularity strategies beyond the four investigated and to broaden environmental impact assessments to include diverse impact categories alongside social considerations.

制造公司通常采用产品族方法，以高效和经济地提供广泛的产品。随着对产品族的可持续性和循环性的日益重视，近几十年来，广泛的研究对这些方面进行了评估。在现有研究的基础上，本研究旨在确定用于评估的最普遍指标和方法。系统的文献综述产生了40篇相关文章。结果表明，现有的指标和方法往往是数据密集型和资源消耗，使得产品族的可持续性和循环性的评估是一个复杂而广泛的过程。研究结果还表明，只有四种循环策略（即再制造，再利用，再循环和翻新）对产品族进行了调查。此外，在这些评估中考虑的大多数循环指标都是特定于策略的，并且不存在用于产品族循环性整体评估的通用指标。此外，大多数研究只关注碳足迹评估，忽视了其他影响类别。此外，社会方面的研究很少在文献中对产品家族进行调查。最后，大多数审查的研究评估了电气和电子设备内产品系列的可持续性和循环性。基于这些发现，本工作强调需要更有效的方法和指标，同时建立经济、环境、社会和循环维度之间的关系，以支持可持续和循环产品系列的发展。还强烈建议评估除所调查的四种循环战略之外的其他循环战略的影响，并扩大环境影响评估，以包括各种影响类别以及社会考虑因素。

Regeneration is a fundamental concept at the heart of the circular economy. This concept emphasizes increasing positive environmental impacts in addition to achieving zero waste. Inspired by this concept, in this research, a mixed-integer linear programming model is developed to design a regenerative supply chain (SC) network in the pomegranate industry under uncertainty. In the investigated network, all pomegranate waste is transported to composting centers. Then, the compost produced by the composting centers is made available to farmers, thus integrating the concept of regeneration with SC operations. A stochastic scenario-based approach is used to deal with the uncertainty of the demand parameter. In addition, a Lagrangian relaxation algorithm is applied in order to solve the problem in large sizes. The validity of the developed algorithm is examined by comparing its results with GAMS results on nine small-sized instances. The results show that the proposed algorithm provides solutions close to GAMS solutions while being faster. Finally, the applicability of the presented model is confirmed through its implementation in a pomegranate industry in Iran.

再生是循环经济核心的一个基本概念。这一概念强调在实现零浪费的同时增加对环境的积极影响。受这一概念的启发，本研究建立了一个混合整数线性规划模型来设计不确定条件下石榴行业的再生供应链网络。在被调查的网络中，所有的石榴废物都被运送到堆肥中心。然后，堆肥中心生产的堆肥提供给农民，从而将再生概念与SC操作相结合。采用基于随机场景的方法处理需求参数的不确定性。此外，为了解决大尺寸的问题，采用了拉格朗日松弛算法。将该算法与GAMS算法在9个小实例上的结果进行了比较，验证了算法的有效性。结果表明，该算法在求解速度较快的同时，提供了接近GAMS的解。最后，通过在伊朗石榴行业的实施，验证了该模型的适用性。
