Optimal use of products with recycled content (PwRC) has emerged as a targeted strategy to reduce construction and demolition (C&D) waste disposal and promote resource circularity in the building and construction sector. Within this context, the role of training in changing project designers’ attitudes and behaviour towards the use of PwRC is poorly investigated on a global scale. Hence, this study aims to develop a framework that shows how training can influence project designers’ attitudes and behaviour towards the optimal use of PwRC through two research questions: (a) what are the factors that influence to change the attitude and behaviour, (b) what are the existing theories and models that support the attitudes and behavioural changes, using a systematic literature review. The review found that changing attitudes and behaviour towards the optimal use of PwRC is influenced by psychological factors, although economic and sociological factors do also have an impact. Of these psychological factors, attitude, knowledge, perceived behaviour control, and subjective norms are more frequently examined. From the economic factors, economic benefits and from sociological factors, collaboration and communication are the primary considerations. The review also suggests that the theory of Planned Behaviour and the Extended Theory of Planned Behaviour are the most widely used theories in this respect. This study contributes to the knowledge development by proposing a seven-element training framework aiming to influence project designers’ attitudes and behavioural change towards the optimal use of PwRC. This is a foundation for further research on circular economy education for construction project designers.

优化使用含有可回收成分的产品（PwRC）已成为减少建筑和拆除（C&；D）废物处置和促进建筑行业资源循环的有针对性的策略。在这种情况下，培训在改变项目设计者对使用PwRC的态度和行为方面的作用在全球范围内的调查很少。因此，本研究旨在通过两个研究问题建立一个框架，表明培训如何影响项目设计师对PwRC最佳使用的态度和行为：(a)影响改变态度和行为的因素是什么，(b)支持态度和行为改变的现有理论和模型是什么，使用系统的文献综述。审查发现，对PwRC最佳利用的态度和行为的改变受到心理因素的影响，尽管经济和社会因素也有影响。在这些心理因素中，态度、知识、感知行为控制和主观规范更常被检查。从经济因素、经济效益和社会因素来看，协作和沟通是首要考虑的因素。综述还表明，计划行为理论和扩展计划行为理论是这方面应用最广泛的理论。本研究提出了一个七要素培训框架，旨在影响项目设计者对PwRC最佳利用的态度和行为改变，从而有助于知识的发展。这为建筑工程设计人员循环经济教育的进一步研究奠定了基础。

While plastic and e-waste dominate public discourse, municipal waste, particularly bulky wastes pose a significant challenge due to their large-scale generation aligning with the enrichment of society. Their efficient collection and keeping in a loop should be considered among the priorities of municipal waste management. Herein, the presented work presents novel composite materials obtained from flexible polyurethane foams used as mattresses and medium-density fiberboards applied in furniture products. Composites have been prepared using compression molding, with the addition of an innovative binder composed of a diisocyanate and inorganic salt, whose in situ decomposition led to the gas generation providing the porous structure and strengthening the interfacial bonding inside the material. The impact of changes induced by the chemical interactions on the appearance, morphology, mechanical, thermal, acoustic and insulation performance of composites has been evaluated. Observed changes pointed to the auspicious conclusions on the further applications of the examined binder composition.

虽然塑料和电子垃圾主导着公共话语，但城市垃圾，特别是大件垃圾，由于其大规模产生与社会的富裕相一致，构成了重大挑战。它们的有效收集和循环应被视为城市废物管理的优先事项之一。本文介绍了一种新型的复合材料，这种复合材料是从用作床垫的柔性聚氨酯泡沫和用于家具产品的中密度纤维板中获得的。复合材料采用压缩成型制备，添加了一种由二异氰酸酯和无机盐组成的创新粘合剂，其原位分解导致气体生成，提供了多孔结构并加强了材料内部的界面结合。评价了化学相互作用引起的变化对复合材料的外观、形态、力学、热、声和绝缘性能的影响。观察到的变化指出了对所检查的粘合剂组成的进一步应用的吉祥结论。

Several studies revealed that date pits, often regarded as agro-industrial waste, possess the potential to be upgraded to value-added products like biofuels. Yet, the majority of the oil extraction studies from date pits relied on the use of environmentally harmful organic solvents which are highly flammable and toxic. Thus, for the first time, this paper is aimed at developing a cost-effective, green, and novel technology for the extraction of oil from date pits using protic ionic liquids. The date pits of eight distinct varieties were structurally characterized, determining their composition of oil (7.6–10.9%), carbohydrates (80.8–84.6%), protein (4.8–8.8%), and ash (1.1–1.7%) based on dry biomass. The quality of oil across these date pits was found to be comparatively similar and well-suited for biofuel production, with oleic, lauric, myristic, and palmitic acid being the most abundant constituents. The screening of six unique protic ionic liquids indicated that Triethylammonium dihydrogen phosphate [TEA][H₂PO₄] exhibited the highest oil extraction of 91.3 mg/g biomass (84% of total oil) from Majdool dates. The investigation of process parameters disclosed that temperature significantly affected oil extraction performance, whereas the reaction duration's impact was found to be minor. The recycling and reuse of [TEA][H₂PO₄] for the extraction of oil from Majdool date seeds throughout four cycles were promising in terms of performance stability, thereby promoting process viability. The outcomes obtained through this study endorse the capacity of low-cost protic ionic liquids to efficiently extract oil from date pits, presenting a viable alternative to toxic organic solvents in this context.

几项研究表明，通常被视为农业工业废物的枣核具有升级为生物燃料等增值产品的潜力。然而，大多数从枣坑中提取油的研究依赖于使用对环境有害的有机溶剂，这些溶剂高度易燃和有毒。因此，本文旨在首次开发一种经济、绿色、新颖的利用质子离子液体从枣核中提取油的技术。对8个不同品种的枣核进行了结构表征，确定了枣核的干生物量组成，分别为油脂（7.6 ~ 10.9%）、碳水化合物（80.8 ~ 84.6%）、蛋白质（4.8 ~ 8.8%）和灰分（1.1 ~ 1.7%）。研究发现，这些枣核上的油质量比较相似，非常适合用于生物燃料生产，其中油酸、月桂酸、肉豆蔻酸和棕榈酸是最丰富的成分。对6种独特的质子离子液体的筛选表明，磷酸二氢三乙基铵[TEA][H2PO4]的提取率最高，为91.3 mg/g生物质（占总油的84%）。工艺参数的研究表明，温度对萃取性能有显著影响，而反应时间对萃取性能的影响较小。[TEA][H2PO4]的回收和再利用在四个循环中从Majdool枣籽中提取油，就性能稳定性而言是有希望的，从而提高了工艺的可行性。本研究的结果表明，低成本的质子离子液体能够有效地从枣核中提取油，在这种情况下，提供了一种可行的替代有毒有机溶剂的方法。

Agriculture plays an essential role in sustaining society, yet the substantial waste produced during agricultural processes presents a major challenge for waste management. Often, agricultural waste is simply burned, posing environmental concerns. To address these issues, the revalorisation of agricultural waste by converting it into high-value nanomaterials offers a promising approach. This work reviews recent advances in the synthesis of nanomaterials from agricultural waste, focusing on materials such as carbonaceous compounds, metal-organic frameworks (MOFs), polymers, and silica-based nanomaterials. It also explores their applications in key sectors, including agriculture, water treatment, and medicine. A feasibility analysis assessed both economic viability and environmental impact, demonstrating that polymeric, carbon-based, and siliceous nanomaterials are particularly cost-effective and environmentally beneficial. This revalorization process not only generates commercially valuable nanomaterials but also promotes sustainable waste management practices. The study underscores the significant potential of agricultural waste as a resource for producing nanomaterials, aligning with both waste reduction and the generation of marketable products.

农业在维持社会方面发挥着至关重要的作用，但农业过程中产生的大量废物对废物管理提出了重大挑战。农业废弃物通常被直接焚烧，造成了环境问题。为了解决这些问题，通过将农业废物转化为高价值纳米材料来重新利用它们提供了一种很有前途的方法。本文综述了从农业废弃物中合成纳米材料的最新进展，重点介绍了碳质化合物、金属有机框架、聚合物和硅基纳米材料等材料。它还探讨了它们在关键部门的应用，包括农业、水处理和医药。可行性分析评估了经济可行性和环境影响，表明聚合物、碳基和硅质纳米材料特别具有成本效益和环境效益。这种再增值过程不仅产生了具有商业价值的纳米材料，而且还促进了可持续的废物管理实践。这项研究强调了农业废弃物作为一种生产纳米材料的资源的巨大潜力，这与减少废弃物和生产适销对路的产品相一致。

Geopolymer concrete (GPC) finds great potential in reducing global warming emissions from the construction sector. The conventional GPC precursor binders (fly ash, slag, metakaolin, silica fume, etc.) and alkaline activators are expensive, pollution-causing, and insufficient to meet the global requirement of concrete. Biochar (BC), agricultural waste produced through pyrolysis has rapidly been employed in cementitious composites since last decade because of its low cost, low carbon footprint, and ecological advantages. This paper presents a detailed review of the compatibility of BC with GPC, the properties (physical, chemical, and mechanical) in cementitious composites, and the chemical suitability of BC with GPC. The physical and chemical properties of BC can be controlled and highly depend on its production method (temperature, pressure, heating rate, resident time). The BC rich in silica and alumina is a feasible alternative to the solid precursor in geopolymer composites by controlling the particle size and mix design. The formation of a highly alkaline BC with water ensured its compatibility as an alkaline activator solution. They revealed comparable strength to GPC produced using conventional activators. Future studies are needed to investigate BC's experimental and practical applications as a precursor and alkaline activator in geopolymer composites.

地聚合物混凝土（GPC）在减少建筑行业的全球变暖排放方面具有巨大潜力。传统的GPC前驱体粘结剂（粉煤灰、矿渣、偏高岭土、硅灰等）和碱性活化剂价格昂贵、污染严重，不能满足混凝土的全球要求。生物炭（BC）是一种通过热解产生的农业废弃物，由于其低成本、低碳足迹和生态优势，在近十年来迅速应用于胶凝复合材料。本文详细介绍了BC与GPC的相容性，胶结复合材料的物理、化学和力学性能，以及BC与GPC的化学适应性。BC的物理和化学性质是可以控制的，并且高度依赖于它的生产方法（温度、压力、加热速率、停留时间）。通过控制颗粒大小和配比设计，富含二氧化硅和氧化铝的BC可以替代固体前驱体用于地聚合物复合材料中。高碱性BC与水的形成保证了其作为碱性活化剂溶液的相容性。他们揭示了与使用传统活化剂生产的GPC相当的强度。BC在地聚合物复合材料中作为前驱体和碱性活化剂的实验和实际应用有待进一步研究。

The rapid growth of urban infrastructure has led to a substantial rise in construction and demolition waste (C&DW), causing environmental issues like overflowing landfills and depletion of natural resources. Recycled concrete aggregates (RCA) offer a sustainable alternative to natural aggregates (NA), helping reduce landfill use and energy consumption by up to 85 % and lowering CO₂ emissions by 90 %, providing significant environmental and economic benefits. However, untreated RCA exhibits lower strength and durability due to adhered mortar and impurities. This review delves into novel and advanced RCA treatment methods and production techniques that enhance RCA's properties. These methods achieve up to 42 % improvement in compressive strength and a 27 % reduction in water absorption. Researchers have found that impact crushers produce higher-quality aggregates compared to jaw or cone crushers. Treatments like acid washing and carbonation enhance particle density and reduce water absorption by 17.5 %. Recycled aggregate concrete (RAC) produced from treated RCA can reach 87 % of the compressive strength of natural aggregate concrete (NAC), with certain combined treatments achieving results close to NAC. Inconsistencies in RCA properties due to various treatments emphasise the need for standardised production and testing guidelines. This review underscores RCA's role in promoting sustainable construction and its potential to significantly mitigate CO₂ emissions, encouraging further research to refine these methods for long-term environmental gains.

城市基础设施的快速发展导致建筑和拆除垃圾（C&；DW）的大幅增加，造成了垃圾填埋场溢出和自然资源枯竭等环境问题。再生混凝土骨料（RCA）是天然骨料（NA）的可持续替代品，有助于减少垃圾填埋场的使用和能源消耗高达85%，降低二氧化碳排放量90%，具有显著的环境和经济效益。然而，未经处理的RCA表现出较低的强度和耐久性，因为粘连砂浆和杂质。本文综述了提高RCA性能的新型和先进的RCA处理方法和生产技术。这些方法可使抗压强度提高42%，吸水率降低27%。研究人员发现，与颚式或圆锥式破碎机相比，冲击式破碎机生产的骨料质量更高。酸洗和碳化等处理提高了颗粒密度，减少了17.5%的吸水率。经处理的再生骨料混凝土（RAC）抗压强度可达到天然骨料混凝土（NAC）抗压强度的87%，某些组合处理可达到接近NAC的效果。由于各种处理方法导致的RCA性能的不一致性强调了标准化生产和测试指南的必要性。本综述强调了RCA在促进可持续建筑方面的作用及其显著减少二氧化碳排放的潜力，鼓励进一步研究以改进这些方法以获得长期的环境收益。

The new European environmental policies for construction focus on sustainability, promoting energy efficiency, recyclable materials and circularity, with an emphasis on waste management. This study enhances gypsum board circularity by recycling polyurethane gypsum ceiling tiles waste into a new precast material for suspended and demountable ceilings. The process treats the waste as a whole, without separating the original raw materials: gypsum, polyurethane foam waste and fiberglass. The objective is to determine a gypsum mixture, incorporating the maximum amount of waste, with suitable mechanical properties, workability and consistency for industrial replication. The research studies the physical and mechanical properties of the new products. During the manufacturing phase of the new plasters, it is reported that citric acid needs to be added to the mixtures to ensure good workability and to delay the setting time. Without pre-calcination, gypsum mortars with recycled ceiling tile show a 7 to 10 % reduction in bulk density, compared to the reference plaster.

新的欧洲建筑环境政策侧重于可持续性，促进能源效率，可回收材料和循环性，重点是废物管理。本研究通过回收聚氨酯石膏吊顶砖废料，使其成为一种新的预制材料，用于悬挂和可拆卸的吊顶，从而提高了石膏板的圆度。该工艺将废物作为一个整体处理，而不分离原始原料：石膏、聚氨酯泡沫废物和玻璃纤维。目的是确定石膏混合物，包含最大数量的废物，具有适当的机械性能，可加工性和工业复制的一致性。研究了新产品的物理力学性能。据报道，在新膏药的制造阶段，需要在混合物中添加柠檬酸以确保良好的和易性并延迟凝固时间。与参考灰泥相比，未经预煅烧的石膏砂浆与可回收的天花板瓷砖相比，体积密度降低了7%至10%。4个试验样品中只有2个达到力学要求，强度分别比对照混合物低35%和60%。最后，创新砂浆的导热系数平均降低16%，提高了材料的绝缘性能。结果表明，对聚氨酯石膏板废弃物进行估价，促进可持续回收的可行性。

The classification and recycling of airport waste has become a key point in developing green airports. However, airport waste classification involves a large number of stakeholders. The influence factors are complex, and the interactions between the stakeholders are not clear. Based on the agent-based model, we sort out the behaviors and driving factors of the three main stakeholders, namely passengers, collectors, and managers, and construct a multi-agent system of airport waste classification and recycling with the coupling of the waste generation subsystem, the recycling subsystem and the strategy formulation subsystem. By the complex system, we analyze the comprehensive effects of different policy strategies. Using the life cycle assessment method, an environmental benefit assessment model for airport waste classification and recycling is established to analyze the environmental benefits of different strategies and find the best strategy for the airport. The results show that implementing policy strategies can significantly change passengers’ waste disposal behavior and more than double their willingness to use green products. The combined strategy of the full-factor change scenario demonstrates a significant effect in optimizing the waste metabolism structure and recyclables disposal structure at the airport, with a 76.9 % increase in the use of green products relative to the BAU scenario. Through the implementation of the combined strategy, recyclable waste recycling can reduce 10.6 t CO₂e and 15.6 % of photochemical oxidant emissions, which is a significant environmental benefit.

机场废弃物的分类和回收利用已成为发展绿色机场的关键。然而，机场垃圾分类涉及到大量的利益相关者。影响因素复杂，利益相关者之间的相互作用不明确。基于agent模型，对旅客、收集者和管理者三个主要利益相关者的行为和驱动因素进行梳理，构建了垃圾产生子系统、回收子系统和策略制定子系统耦合的机场垃圾分类回收多agent系统。通过复杂系统分析不同政策策略的综合效应。运用生命周期评价方法，建立机场垃圾分类回收的环境效益评价模型，分析不同策略的环境效益，寻找最适合机场的策略。结果表明，实施政策策略可以显著改变乘客的垃圾处理行为，使其使用绿色产品的意愿增加一倍以上。全因子变化情景组合策略对机场废弃物代谢结构和可回收物处理结构的优化效果显著，绿色产品使用量较BAU情景提高76.9%。通过实施联合战略，可回收废弃物回收可减少10.6 t CO2e和15.6%的光化学氧化剂排放，环境效益显著。

Statistical entropy (SE) is a method to quantify distributions of any metric. In material flow analysis, SE was initially applied to examine the distribution of a single chemical element over a set of material flows. This made it possible to quantify the entropy change caused by a process with respect to a single substance. However, using Shannon's SE equation in another way, SE can also be applied to the distribution of all substances within one specific material flow. This paper presents how these two approaches are actually connected and how the first can be derived from the second in a mathematically sound, straightforward way. Finally, we show how to compute the combined SE for a set of material flows with respect to several selected substances.

统计熵（SE）是一种量化任何指标分布的方法。在物料流分析中，统计熵最初被用于研究单一化学元素在一组物料流中的分布。这使得量化单一物质的过程所引起的熵变成为可能。然而，以另一种方式使用香农 SE 方程，SE 也可以应用于特定物质流中所有物质的分布。本文介绍了这两种方法之间的实际联系，以及如何以一种数学上合理、简单的方式从第二种方法推导出第一种方法。最后，我们还展示了如何计算一组物料流中几种选定物质的综合 SE。

The petrochemical industry is a (key pillar) of chemical production and has relatively stable product demand in a long term, but it faces great decarbonization challenges due to the high energy consumption and complex industrial structure. To tackle this, a flow-land-infrastructure-petrochemical (FLIP) multi-factor model is developed with integration of material and energy flow analysis and decoupling assessment, targeting industrial carbon peaking via industrial structure upgrading and production efficiency improvement of four-digit level petrochemical sub-sectors. A nationally leading petrochemical industrial park was then selected to validate the model's effectiveness and robustness. Through the model optimization, the park could achieve 19 % and 30 % of CO₂e emission reductions in 2025 and 2030 respectively, compared with emissions in the scenario without intervention. The overall carbon productivity could rise by 89 % with a decoupling index of -0.15 between economic growth and carbon emissions during 2020–2030, showing a feasible carbon peaking pathway. Infrastructure with lock-in emissions needs energy system transformation and adjacent industrial symbiosis from a regional perspective, while promotion targets and entry thresholds of carbon productivity should be individually tailored for each stock and incremental manufacturing sub-industry. The model could be extended to other petrochemical clusters and emission-intensive industries, synergistically addressing the effects of structure upgrading and efficiency progress to support practical and economically sustainable carbon peaking pathway formulation.

石化行业是化工生产的（重点支柱），长期具有相对稳定的产品需求，但由于能耗高，产业结构复杂，面临着很大的脱碳挑战。为此，结合物能流分析和解耦评估，构建了流-陆-基建-石化（FLIP）多因素模型，以四位数石化细分行业为目标，通过产业结构升级和生产效率提升实现工业碳峰值。然后选取一个全国领先的石化工业园区来验证模型的有效性和稳健性。通过模型优化，与不干预情景相比，2025年和2030年，园区的二氧化碳排放量可分别减少19%和30%。2020-2030年，经济增长与碳排放的脱钩指数为-0.15，总体碳生产率可提高89%，显示出一条可行的碳峰值路径。碳排放锁定型基础设施需要从区域角度进行能源系统转型和相邻产业共生，碳生产率的提升目标和进入门槛应针对存量和增量制造子产业进行个性化定制。该模型可以推广到其他石化产业集群和排放密集型产业，协同解决结构升级和效率提升的影响，为制定切实可行、经济可持续的碳调峰路径提供支持。
