ABSTRACT In the present review, the consideration has paid on various possible applications of post-consumer polyvinyl chloride flex banners (vinyl flex banners), focusing on their process chemistry, process parameters, and methodologies. The vinyl flex banners are mainly composed of calcium carbonate, polyvinyl chloride resin, polyester fabric, plasticisers and additives. From the intensive literature search, it is observed that post-consumer vinyl flex banner (PCVFB) materials have the potential to use in various fields. The PCVFB materials can be reused as received for various possible applications, such as water-proof roof covers, vehicle covers, food grain covers, tarpaulins, sitting mats, bags, etc. Critically, they can be recycled by using suitable preparation process for different applications, such as footwear, geotextiles, canal linings, ropes, and pipes. Further, the PCVFB material can be used as one of the ingredients for concrete materials. To the finest of our information, it can be further suggested that there is a scope to prepare low-cost wood-plastic composites (WPC), and adhesive/glue material from PCVFB for diverse applications. The use of PCVFB for various possible applications can reduce the accumulation of solid waste and can provide a cleaner and greener environment. Graphical Abstract
在目前的回顾中,考虑了消费后聚氯乙烯柔性横幅(乙烯基柔性横幅)的各种可能的应用,重点是它们的工艺化学,工艺参数和方法。乙烯基柔性横幅主要由碳酸钙、聚氯乙烯树脂、聚酯织物、增塑剂和助剂组成。从密集的文献检索中,可以观察到,消费后乙烯基柔性横幅(PCVFB)材料具有在各个领域使用的潜力。PCVFB材料可以重复使用,用于各种可能的应用,如防水屋顶盖,车辆盖,粮食盖,防水油布,坐垫,袋子等。重要的是,它们可以通过使用合适的制备工艺进行回收,用于不同的应用,如鞋类、土工织物、运河衬里、绳索和管道。此外,PCVFB材料可作为混凝土材料的配料之一。据我们所知,可以进一步表明,从PCVFB中制备低成本木塑复合材料(WPC)和粘合剂/胶水材料用于各种应用是有可能的。在各种可能的应用中使用PCVFB可以减少固体废物的积累,并可以提供更清洁和更环保的环境。图形抽象

The devastating impacts of increasingly frequent and wideranging climatic events from tornadoes to hurricanes, wild floods to extreme droughts, freezing cold to extreme heat periods, melting ice and sea level rises to wildfires and deforestation have rapidly evolved the global mindset from climate change to climate crisis, and public demands for climate emergency declarations. The unprecedented level of global ‘eco-enthusiasm’, in particular among younger generations whose quality of life is most likely to be deeply affected, appear to have finally gained the desired traction among key decision makers and stakeholders. The COP26 conference in Glasgow was the largest gathering of governments, industrial leaders and community representatives who appeared to compete in shining the light on their sustainability aspirations and firm commitments to reduce negative impacts on the environment. There was a clear and unstoppable excitement prior to this gathering, seeing this as a critical moment in history with potential to make notable changes towards a sustainable future. Undoubtedly, the long-term successes or failures of COP26 will be scrutinised and assessed in the coming weeks and months, however, a common observation among activists is that the agreements on improvement and reduction targets are not ambitious enough to address the urgent needs and investment commitments are not proportional to size of the challenges ahead. For example, the United Nations Emissions Gap Report (2021) stated that the planet was on course for a dangerous 2.7°C of global warming just before COP26. Based on new announcements made during the Conference, it is estimated that we are now on a path to between 1.8°C and 2.4°C of warming, with further agreement among signatories to revisit their commitments by the end of 2022 to ‘keep the 1.5°C ambition under the Paris Agreement alive’ (COP26 2011). The paramount importance of the role of engineering research and innovation to achieve short-term targets (now until 2030) to build a sustainable future, encapsulated by the United Nations Sustainable Development Goals (UN-SDGS 2015), is now very well defined and understood. But, perhaps the most significant lesson from COP26 is the recognition and final acceptance of paralysing complexities in generating global, coherent and transitional strategies and plans to avoid irreversible changes in our eco-system. This highlights the importance of long-term targets (2030–2050) to become resilient towards a set of alternative ‘earth futures’ that are emerging due to the common reality of the current climate crisis. In this context the key research questions, therefore, are ‘how do we identify and define these alternative earth futures?’ and ‘what are the long-term engineering challenges in building resilience towards these futures?’. Among the many roadmaps and scenarios that have been published, one approach is the utilisation of a two axes scenario planning methodology. This has been used
从龙卷风到飓风,从洪水到极端干旱,从严寒到极端高温,从冰雪融化和海平面上升到野火和森林砍伐,越来越频繁和范围越来越广的气候事件的破坏性影响迅速使全球思维从气候变化转变为气候危机,并使公众要求宣布气候紧急状态。全球前所未有的“生态热情”,特别是生活质量最有可能受到深刻影响的年轻一代的“生态热情”,似乎终于在关键决策者和利益攸关方中获得了预期的牵引力。在格拉斯哥举行的COP26会议是政府、工业领袖和社区代表的最大聚会,他们似乎在竞争,以彰显他们的可持续发展愿望和减少对环境的负面影响的坚定承诺。在这次会议之前,人们明显感到兴奋,认为这是历史上的一个关键时刻,有可能朝着可持续的未来做出显著改变。毫无疑问,COP26的长期成功或失败将在未来几周和几个月内被仔细审查和评估,然而,活动人士普遍认为,关于改善和减少目标的协议不够雄心勃勃,不足以解决迫切需求,投资承诺与未来挑战的规模不成比例。例如,《联合国排放差距报告(2021年)》指出,就在第26次缔约方会议之前,地球正朝着2.7°C的全球变暖危险方向发展。根据会议期间发布的新公告,估计我们现在正走在1.8°C至2.4°C的变暖道路上,各签署国进一步同意在2022年底之前重新审视其承诺,以“保持《巴黎协定》1.5°C的目标”(COP26 2011)。工程研究和创新对于实现联合国可持续发展目标(UN-SDGS 2015)所概括的短期目标(从现在到2030年)、建设可持续未来的作用至关重要,这一点现在得到了很好的定义和理解。但是,也许COP26最重要的教训是,认识到并最终接受了在制定全球连贯的过渡性战略和计划以避免我们的生态系统发生不可逆转的变化方面令人瘫痪的复杂性。这突出了长期目标(2030-2050年)的重要性,以适应由于当前气候危机的共同现实而出现的一系列替代“地球未来”。因此,在这种背景下,关键的研究问题是“我们如何识别和定义这些可供选择的地球未来?”以及“在建立应对这些未来的韧性方面,有哪些长期的工程挑战?”在已发表的许多路线图和情景中,一种方法是利用双轴情景规划方法。多年来,它一直被用于提高各种应用中战略规划的质量,特别是用于确定将塑造我们生态系统未来的关键因素。读者可参考Rahimifard等人(2013)了解更多细节。本研究中提出的关键因素首先是我们对环境的负面影响的严重性,这在COP26上得到了广泛的讨论,其次是资源的迅速枯竭,这可能没有得到同样程度的审议,但不可否认的是,它将以全球人口维持生活方式的方式产生不可估量的经济和社会政治后果。利用这些因素,图1描绘了地球生态系统的四种可能情景(或未来),标记如下:

ABSTRACT In the Greater Houston Area, mobile sources contribute to the highest share of NOx emissions and the second-highest share of VOC emissions. The Houston METRO system that operates public buses is a key element of Houston’s infrastructures that could reduce the emissions of criteria air pollutants (CAPs) and greenhouse gases (GHGs), thus improving the regional air quality. We used life-cycle assessment (LCA) and life-cycle cost analysis (LCCA) to evaluate the environmental sustainability of electric buses and compared it to diesel buses. The LCA simulations demonstrate that life-cycle emissions of GHGs, VOCs, NOx, and black carbon associated with electric buses are lower than conventional diesel and diesel hybrid buses. These lower emissions are mainly attributed to the fact that natural gas currently makes up about 50% of the fuel used to generate electricity in Texas. However, other emissions such as PM10, PM2.5, SOx, N2O, and primary organic carbon are higher and would lead to the higher environmental cost of electric buses than diesel buses. The environmental cost analysis estimates that the annual cost savings of electric buses in 2040 would significantly support the long-term goal of environmental sustainability in the Greater Houston area.
摘要在大休斯敦地区,移动源在NOx排放中所占比例最高,在VOC排放中所属比例第二。运营公共巴士的休斯顿地铁系统是休斯顿基础设施的关键要素,可以减少标准空气污染物(CAP)和温室气体(GHGs)的排放,从而改善地区空气质量。我们使用生命周期评估(LCA)和生命周期成本分析(LCCA)来评估电动公交车的环境可持续性,并将其与柴油公交车进行比较。LCA模拟表明,电动公交车的温室气体、挥发性有机物、氮氧化物和黑碳的生命周期排放量低于传统柴油和柴油混合动力公交车。这些较低的排放量主要归因于天然气目前占德克萨斯州发电燃料的50%左右。然而,PM10、PM2.5、SOx、N2O和一次有机碳等其他排放量更高,这将导致电动公交车的环境成本高于柴油公交车。环境成本分析估计,2040年电动公交车的年度成本节约将大大支持大休斯敦地区环境可持续性的长期目标。

ABSTRACT The energy sector is known for its enormous investments, despite the erratic behaviour of the oil market (e.g. changes in crude oil prices). Therefore, strategic and tactical planning of the Hydrocarbon supply chain (HCSC), considering market uncertainty, is a significant area of research. HCSC construction involves the integration of crude oil and natural gas supply chains (SCs). In this study, a stochastic multi-objective optimization model is developed for the tactical planning of HCSC. The model considers price and demand uncertainty by formulating a two-stage stochastic programming model. Financial objectives are considered in terms of cost minimization and revenue maximization, while a non-financial objective is considered in terms of depletion rate minimization (i.e. reserves sustainability maximization). The model assists the decision-maker in quantifying the amount of production required to meet demand under different scenarios. Furthermore, the proposed model assists in evaluating the trade-offs among alternatives. A real-world HCSC is used to elucidate the practicability of the model, and some managerial insights are derived by conducting a sensitivity analysis. For instance, production can be reduced during high demand periods to maintain enough reserves, and the excess demand can be satisfied from the outside market based on medium-term contracts.
摘要尽管石油市场的行为不稳定(例如原油价格的变化),但能源行业以其巨大的投资而闻名。因此,考虑到市场的不确定性,碳氢化合物供应链的战略和战术规划是一个重要的研究领域。HCSC建设涉及原油和天然气供应链(SC)的整合。在本研究中,建立了一个用于HCSC战术规划的随机多目标优化模型。该模型通过建立两阶段随机规划模型来考虑价格和需求的不确定性。财务目标是根据成本最小化和收入最大化来考虑的,而非财务目标则是根据损耗率最小化(即储量可持续性最大化)来考虑的。该模型有助于决策者量化不同情景下满足需求所需的产量。此外,所提出的模型有助于评估备选方案之间的权衡。使用真实世界的HCSC来阐明该模型的实用性,并通过进行敏感性分析得出一些管理见解。例如,在高需求时期可以减少产量以保持足够的储量,而超额需求可以根据中期合同从外部市场得到满足。

ABSTRACT The manufacturing sector accounts for 40% and 25% of global energy and resources consumption respectively. Machining is one of the most power-intense operations in the manufacturing sector making a significant contribution to the environmental footprint. The purpose of this study is to identify the key parameters that contribute towards the environmental impacts of conventional turning. A set of experiments was designed using the Taguchi L9 method. Experiments were performed to analyse the electrical energy consumption, metalworking fluid (MWF) consumption, surface roughness, and material removal rate during turning of AISI P20 with both wet and dry machining. A life cycle assessment (LCA) was conducted to assess the environmental performance of turning. A multi-response optimisation was performed to identify the optimum operating conditions. The results show that turning with wet machining yields better machining and environmental performance compared to dry machining. The LCA results reveal that electrical energy is the highest contributor under most of the impact categories, while the effect of MWF is negligible. The use of workpiece material and cutting insert material contribute significantly to the impacts under aquatic ecosystem and resource depletion damage categories. Further, optimum parameters were proposed considering both machining performance and environmental impact.
制造业分别占全球能源和资源消耗的40%和25%。机械加工是制造业中最耗电的操作之一,对环境足迹做出了重大贡献。本研究的目的是确定传统车削对环境影响的关键参数。采用田口L9法设计了一组实验。通过实验分析了aisip20干湿车削过程中的电能消耗、金属加工液(MWF)消耗、表面粗糙度和材料去除率。采用生命周期评价(LCA)方法对转弯的环境性能进行了评价。采用多响应优化方法确定最佳操作条件。结果表明,与干式车削相比,湿式车削具有更好的加工性能和环保性能。LCA结果表明,在大多数影响类别中,电能是最大的贡献者,而MWF的影响可以忽略不计。工件材料和切削刀具材料的使用对水生生态系统和资源枯竭破坏类别的影响有显著影响。在此基础上,提出了综合考虑加工性能和环境影响的优化参数。

ABSTRACT Municipal solid remains an issue that needs to be addressed globally towards a more circular economy and lower environmental impacts. In Colombia, over 96% of municipal solid wastes are landfilled, with little recycling or revalorisation of wastes and several environmental implications. With the technological development of different waste-to-energy routes, the energy revalorisation of solid wastes is increasingly becoming an attractive business opportunity. The waste-to-energy potential of the Atlantic Department (Colombia) was estimated based on the characteristics and daily availability of municipal solid wastes for different technologic routes. The implementation of the technological routes discussed could replace from 1 to 49 % of the demand for energy carriers like natural gas, electricity, or gasoline. This energy potential could replace from 2 to 106% of the energy demanded by the power generation, transport, residential, industrial, and commercial sectors. Furthermore, these technology routes could reduce greenhouse gas emissions by 46 to 92% of the greenhouse gas emissions resulting from landfilling. These results stress the need to upgrade energy policies in the country and to introduce new incentives to overcome economic and other barriers precluding the widespread use of waste-to-energy technologies.

城市固体仍然是一个需要在全球范围内解决的问题,以实现更循环的经济和更低的环境影响。在哥伦比亚,超过96%的城市固体废物被填埋,几乎没有废物的回收或重新利用,并造成一些环境影响。随着各种废物能源转化途径的技术发展,固体废物的能源转化日益成为一个有吸引力的商机。大西洋部(哥伦比亚)的废物转化为能源的潜力是根据不同技术路线的城市固体废物的特点和每日可用性来估计的。所讨论的技术路线的实施可以取代对天然气、电力或汽油等能源载体的1%至49%的需求。这种能源潜力可以替代发电、运输、住宅、工业和商业部门所需能源的2%至106%。此外,这些技术路线可以减少填埋产生的温室气体排放量的46%至92%。这些结果强调需要改进该国的能源政策,并采取新的奖励措施,以克服阻碍广泛使用废物转化为能源技术的经济和其他障碍。缩写:收听儿童节目(TIK);父母反射功能(PRF)澳大利亚新西兰临床试验注册(ANZCTR)编号:ACTRN12618000310268

Furthermore, these technology routes could reduce greenhouse gas emissions by 46 to 92% of the greenhouse gas emissions resulting from landfilling. These results stress the need to upgrade energy policies in the country and to introduce new incentives to overcome economic and other barriers precluding the widespread use of waste-to-energy technologies.

ABSTRACT Additive Manufacturing helps to develop production alternatives with new technologies and less environmental impacts. The comparative analysis was performed between two manufacturing processes using black recycled Acrylonitrile Butadiene Styrene (ABS) pellets to evaluate the potential environmental impacts between Injection moulding and Fused Deposition Modelling (FDM). The Life Cycle Assessment (LCA) and the Unit Process Life Cycle Inventory (UPLCI) methodology were adopted, which resulted in an impact assessment separated by operation modes and subunits of the equipment. The LCA results indicate a lower environmental impact of the FDM when the aim is to produce a batch size smaller than 14 parts. For batch sizes above 50 parts, the Injection moulding process generated less impact to the Global Warming Potential (GWP) and Cumulative Energy Demand (CED). The printing stage contributed the most to generating impacts for the FDM. In the Injection moulding process, the main responsible for generating impacts were the injection phase. Mechanical tensile tests were carried out with the parts obtained by the FDM with different infills (25%, 50%, 75% and 100%), and it was observed that parts with 100% infill obtained the best relation between mechanical properties and environmental impacts.
摘要增材制造有助于开发具有新技术和较少环境影响的生产替代品。使用黑色回收丙烯腈-丁二烯-苯乙烯(ABS)颗粒对两种制造工艺进行了比较分析,以评估注塑成型和熔融沉积建模(FDM)之间的潜在环境影响。采用了生命周期评估(LCA)和机组工艺生命周期清单(UPLCI)方法,这导致了按设备的运行模式和子单元进行的影响评估。LCA结果表明,当目标是生产小于14个零件的批量时,FDM对环境的影响较小。对于50个零件以上的批量,注塑工艺对全球变暖潜能值(GWP)和累计能源需求(CED)的影响较小。印刷阶段对FDM产生的影响最大。在注塑过程中,产生冲击的主要原因是注塑阶段。对FDM获得的具有不同填充物(25%、50%、75%和100%)的零件进行了机械拉伸试验,观察到具有100%填充物的零件获得了机械性能与环境影响之间的最佳关系。

ABSTRACT It is not very unrealistic to lookout for one-point solutions in the case of service-based industries. Similarly, there is a need of establishing Electric Vehicle Service Centres (EVSC), which could be one-point solution to the customers. These modern service stations are converged towards promoting the idea of sustainability in the environment. This would provide the services solely for Electric Vehicles (EVs), an emerging application of sustainable resources. However, considering a range of services from charging infrastructure to the battery swapping module in a single EVSC, some numerous challenges and risk factors get invoked. For EVSCs too, it is thus essential to analyze every risk factor associated with its practicability. In this work, authors have identified thirteen challenges posed by this industry by consulting experts from the same genre, and thus a model is developed deploying Fuzzy to arrange these challenges in a hierarchy level posed by each criterion. The results are exclusively expected to benefit the policymakers of the EVSC industry to help them plan their businesses on the intensity of challenges they face from each factor. It shall further aid in designing more efficient and robust frameworks to ensure a better servicing mechanism for EVSCs targeting one-point solution schemes.
在以服务为基础的行业中寻找单点解决方案并不是很不现实。同样,有必要建立电动汽车服务中心(EVSC),这可能是客户的一点解决方案。这些现代化的服务站旨在促进环境的可持续性。这将仅为电动汽车(ev)提供服务,这是可持续资源的新兴应用。然而,考虑到在单个EVSC中从充电基础设施到电池交换模块的一系列服务,会调用许多挑战和风险因素。因此,对于EVSCs来说,分析与其实用性相关的每一个风险因素是至关重要的。在这项工作中,作者通过咨询同一类型的专家,确定了该行业提出的13个挑战,因此开发了一个模型,利用Fuzzy将这些挑战安排在每个标准构成的层次结构中。研究结果预计将有利于EVSC行业的决策者,帮助他们根据每个因素所面临的挑战强度来规划业务。它将进一步有助于设计更有效和稳健的框架,以确保为针对一点解决方案的evsc提供更好的服务机制。

ABSTRACT Original Equipment Manufacturers (OEM) are shifting towards remanufacturing, signalling growth in new investments in remanufacturing. It is a noticeable global trend owing to the popularity of circularity and sustainability concepts, catalysed by environmental legislations and profit motives. Thus, the development of effective business models for remanufacturing is essential. However, capturing the entirety of business components essential for remanufacturing is yet to be seen in the industry. The purpose of this research is to develop a comprehensive business model for automotive parts remanufacturing considering all major business components, namely: customer segments; value propositions; channels; customer relationships; revenue streams; key resources; key activities; key partnerships; and cost structure. In this pursuit, a thematic analysis of related literature was conducted to define the identified business components. The Business Model Canvas framework was used to present the developed business model in the context of automotive parts remanufacturing. The resultant business model with nine components is expected to support decision-making for investors and entrepreneurs in the automotive remanufacturing industry.
摘要原始设备制造商(OEM)正在转向再制造,这标志着再制造新投资的增长。这是一个引人注目的全球趋势,因为在环境立法和利润动机的推动下,循环性和可持续性概念很受欢迎。因此,开发有效的再制造商业模式至关重要。然而,捕获再制造所必需的全部业务组件在行业中尚待观察。本研究的目的是开发一种综合的汽车零部件再制造商业模式,考虑所有主要业务组成部分,即:客户细分市场;价值主张;渠道;客户关系;收入流;关键资源;关键活动;关键伙伴关系;以及成本结构。为此,对相关文献进行了专题分析,以确定已确定的业务组成部分。商业模式画布框架用于在汽车零部件再制造的背景下展示已开发的商业模式。由此产生的由九个组成部分组成的商业模式有望为汽车再制造行业的投资者和企业家提供决策支持。

ABSTRACT Different wireless power transfer (WPT) technologies using inductive, capacitive, or optical coupling, and microwaves have been theoretically investigated and many have been employed in commercial products. WPT technologies have their own advantages and drawbacks and have been individually studied. This article envisions a concept of universal and ubiquitous wireless power transfer (U2WPT), in which power can be wirelessly transferred between any entity, whether stationary or in-motion, as long as they are equipped with appropriate energy transmitters and receivers. The realisation of such a U2WPT concept allows for the analysis of the sustainability of existing WPT systems in a unified manner, and to potentially overcome their limitations and engender greater energy mobility, flexibility, and sustainability. In addition, market mechanisms for U2WPT systems are introduced, along with an analysis of the benefits engendered in terms of economic, environmental, human and social outcomes, and improvement of energy and transportation systems. Finally, a discussion on the realisation of the U2WPT concept including policy implications, and recommendations for future research directions essential to their deployment is presented.
利用电感、电容或光耦合和微波的不同无线电力传输(WPT)技术已经在理论上进行了研究,许多技术已经应用于商业产品。WPT技术各有优缺点,已被单独研究。本文设想了一个通用和无处不在的无线电力传输(U2WPT)的概念,其中电力可以在任何实体之间无线传输,无论是静止的还是运动的,只要它们配备了适当的能量发射器和接收器。实现这样一个U2WPT概念,可以以统一的方式分析现有WPT系统的可持续性,并有可能克服其局限性,产生更大的能源流动性、灵活性和可持续性。此外,还介绍了U2WPT系统的市场机制,并分析了在经济、环境、人类和社会结果方面产生的效益,以及改善能源和运输系统。最后,讨论了U2WPT概念的实现,包括政策影响,并提出了对其部署至关重要的未来研究方向的建议。
