Evaluating project viability often relies on economic analysis with environmental impacts either evaluated subjectively in a separate analysis or not at all. The concept of the study was to express environmental impacts as cash flow equivalents through the life of the project to directly compare environmental and economic impacts in a standard cost-benefit analysis. Embodied energy accounting methodologies have been used as a novel method for converting environmental impacts of a project to monetary terms. With environmental impacts expressed in monetary terms on an annual basis, the present value of the environmental impacts could be calculated using an appropriate interest rate based on environmentally-focused investment for a similar project. Application of this method to a case study based on a recent wetland restoration project in eastern Canada demonstrated that inclusion of environmental impact valuation in the analysis of the project changes the project from a net-cost (CAN$-23.5 million) to a net-benefit (CAN$3.7 million) and providing a clear justification for the project. This method is applicable to projects with significant environmental impacts and can be used in a project approval process or for selecting between project approaches.
评估项目可行性通常依赖于经济分析,环境影响要么在单独的分析中主观评估,要么根本不评估。该研究的概念是将环境影响表示为项目整个生命周期的现金流等价物,以便在标准成本效益分析中直接比较环境影响和经济影响。具体能源核算方法已被用作将项目的环境影响转换为货币术语的新方法。由于环境影响是按年以货币形式表示的,因此环境影响的现值可以根据类似项目的以环境为重点的投资采用适当的利率来计算。将该方法应用于加拿大东部最近的一个湿地恢复项目的案例研究表明,在项目分析中纳入环境影响评估将项目从净成本(- 2350万加元)转变为净效益(370万加元),并为项目提供了明确的理由。该方法适用于具有重大环境影响的项目,可用于项目审批过程或在项目方法之间进行选择。

The increasing demand for renewable energy solutions has led to the exploration of sustainable biofuels like biogas and biodiesel for power generation. However, the combined use of these fuels in small-scale dual-fuel systems remains underexplored. This study aims to evaluate the performance of a dual-fuel diesel generator operating with waste-derived biodiesel and biogas. Biodiesel was synthesized from waste frying oil through transesterification, and biogas with a methane content of 63.5 % was sourced from an agricultural digester. A 5 kVA diesel generator was modified for dual-fuel operation and tested under varying electrical loads and biodiesel blend ratios (B8, B20, B50, B80, and B100). Results revealed that dual-fuel operation increased power output by up to 21.77 % compared to diesel-only mode and achieved liquid fuel savings of 28.74 % to 31.08 % across the blends. Efficiency in normal mode remained higher, peaking at 25.74 % for B100. The findings demonstrate the feasibility of integrating biogas and biodiesel for small-scale power generation, offering a cost-effective and sustainable alternative for off-grid applications. Future research should address emissions analysis, biogas supply optimization, and scalability for broader implementation.
对可再生能源解决方案日益增长的需求促使人们探索可持续的生物燃料,如沼气和生物柴油,用于发电。然而,这些燃料在小型双燃料系统中的联合使用仍未得到充分探索。本研究旨在评估一种双燃料柴油发电机的性能,该发电机使用废物衍生的生物柴油和沼气。以废煎炸油为原料,通过酯交换反应合成了生物柴油,甲烷含量为63.5%的沼气来源于农业沼气池。对一台5kva柴油发电机进行了双燃料运行改造,并在不同电力负荷和生物柴油混合比例(B8、B20、B50、B80和B100)下进行了测试。结果显示,与纯柴油模式相比,双燃料运行可将动力输出提高21.77%,并在混合燃料中节省28.74%至31.08%的液体燃料。正常模式下的效率仍然较高,B100的峰值为25.74%。这一发现证明了将沼气和生物柴油结合起来用于小规模发电的可行性,为离网应用提供了一种具有成本效益和可持续的替代方案。未来的研究应该解决排放分析、沼气供应优化和更广泛实施的可扩展性问题。

Co-combustion of coal and biomass reduced the net Carbon di-oxide emissions. The fluidized bed technology is best suited to burn biomass and coal combinations without major modifications to the combustion systems. Experimentation of large-scale CFBC boilers is uneconomical and time-consuming. Mathematical modelling has gained visibility in the last several decades and allows researchers to explore different circumstances and design optimization. The current research presents mathematical modelling of an industrial scale CFBC boiler (165 TPH CFBC Boiler for 100 MWe CPP) functioning in Hindalco Industries, Odisha, India, using co-combustion of coal and sawdust biomass (90 % coal + 10 % sawdust). The simulation is performed using the Eulerian-Eulerian multifluid model by considering the four different Eulerian phases (coal, sawdust, sand, and mixture gas). The kinetic theory of granular (KTGF) flows is used to model the collisions between bed material and fuel particles. User-defined functions (written in C programming language) are employed to model the reaction kinetics of heterogeneous chemical reactions. The numerical methodology is validated with the onsite industrial data of pressure drop, fluidized bed height, suspension density, bed voidage, and temperature variations. The comparison of pressure drop, fluidized bed height, axial velocity profiles, sand and mixture gas temperature variations, gas compositions, and pollutant emissions (Sulfur di-oxide and nitrous oxide) using solo coal and blended fuel are presented in the result section. Hydrodynamics steady reveals the recirculation of sand particles in the fluidized bed region of the boiler. The comparison of solo coal and blended fuel combustion study reveals an 11.42 % reduction in pressure drop, 13.17 % increase in oxygen mass fraction, 10.63 % reduction in carbon mono oxide mass fraction, 16.26 % reduction in Sulfur di-oxide mass fraction, and 7.17 % reduction in nitrous oxide mass fraction is observed at the boiler outlet while using the 10 % sawdust blends with 90 % coal.
煤和生物质的混合燃烧减少了二氧化碳的净排放量。流化床技术最适合燃烧生物质和煤组合,而不需要对燃烧系统进行重大修改。大型循环流化床锅炉试验既不经济又费时。在过去的几十年里,数学建模已经获得了知名度,并允许研究人员探索不同的情况和设计优化。目前的研究提出了工业规模CFBC锅炉的数学模型(165 TPH CFBC锅炉100 MWe CPP)在印度奥里萨邦的Hindalco工业公司运行,使用煤和木屑生物质(90%煤+ 10%木屑)共燃烧。模拟采用欧拉-欧拉多流体模型,考虑了四种不同的欧拉相(煤、锯末、砂和混合气)。利用颗粒流动动力学理论(KTGF)模拟了床层物料与燃料颗粒之间的碰撞。采用用户定义函数(用C语言编写)来模拟非均相化学反应的反应动力学。数值方法与现场工业数据的压降、流化床高度、悬浮密度、床层空隙和温度变化进行了验证。结果部分介绍了单独使用煤和混合燃料时的压降、流化床高度、轴向速度分布、砂和混合气体温度变化、气体成分和污染物排放(二氧化硫和氧化亚氮)的比较。流体力学稳态分析揭示了砂粒在锅炉流化床区的再循环。结果表明,10%木屑与90%煤混合燃烧后,锅炉出口压降降低11.42%,氧质量分数提高13.17%,一氧化二碳质量分数降低10.63%,二氧化二硫质量分数降低16.26%,氧化亚氮质量分数降低7.17%。

Potato production is seasonal in nature, resulting in the requirement for product storage in order to meet ongoing demands of consumer markets. Maintaining potato quality in medium- to long-term storage is temperature dependent and typically requires refrigeration to maintain a stable storage environment. This represents an energy demand that adds to production costs and greenhouse gas emissions using conventional fossil-based energy supplies. On-site renewable technology deployment presents opportunities to mitigate against these, however, the appropriate deployment of such technologies requires a site-specific understanding of energy demand and available renewable energy resources to best match the energy resources to demand. This research case study makes the case for on-site distributed wind electricity generation compared with solar PV in commercial-scale potato production in Ireland. It is based on high-resolution multi-annual measurements of electricity demand along with measurements and modelling of available on-site wind and solar resources at a commercial-scale producer's site. The results show that despite higher capital costs at present, distributed wind energy can be more appropriate for the given energy demand and resource profiles. A critical need to embed energy demand and resource matching criteria in government supports for on-site renewable energy deployment is highlighted. The learnings from this case study may be of benefit to numerous prospective stakeholders such as end-users, agricultural bodies and government agencies engaged with energy and carbon reduction in agriculture.
马铃薯生产是季节性的,因此需要产品储存,以满足消费市场的持续需求。在中长期储存中保持马铃薯品质取决于温度,通常需要冷藏以保持稳定的储存环境。这代表了一种能源需求,增加了使用传统化石能源供应的生产成本和温室气体排放。现场可再生能源技术部署提供了缓解这些问题的机会,然而,这种技术的适当部署需要对特定地点的能源需求和可用的可再生能源进行了解,以最佳地匹配能源需求。本研究案例研究将现场分布式风力发电与爱尔兰商业规模马铃薯生产中的太阳能光伏发电进行了比较。它基于高分辨率的多年电力需求测量,以及商业规模生产商现场可用风能和太阳能资源的测量和建模。结果表明,尽管目前的投资成本较高,但分布式风能可以更适合给定的能源需求和资源概况。强调了将能源需求和资源匹配标准纳入政府对现场可再生能源部署的支持的迫切需要。本案例研究的经验教训可能对许多潜在的利益相关者有益,如终端用户、农业机构和从事农业能源和碳减排的政府机构。

Energy is an indispensable resource in the seafood processing industry. This pioneering study explores energy efficiency using Specific energy consumption (SEC) model in Kerala's seafood processing industry, shedding light on its energy dynamics amidst growing calls for conservation and cost optimization. With an average Specific Energy Consumption (SEC) of 159.2 kWh/MT and an energy cost of 965.9 INR/MT, the industry faces notable energy challenges. The study finds a moderate correlation (0.748) between production and energy consumption, and strong correlations between production and energy cost (0.763), and energy consumption and energy cost (0.992), highlighting the direct link between energy use and costs. Regression analysis confirms that SEC significantly influences energy costs, emphasizing the need for efficient energy management. The research advocates for adopting ISO 50001:2018, integrated with the Food-Energy-Water (FEW) Nexus, as a framework for optimizing energy and resource use. A customized action plan for implementing this standard in shrimp processing facilities aims to reduce consumption, cut costs, and enhance sustainability, offering a robust foundation for future energy efficiency initiatives in the sector.

This present review is significant as it aligns with the global push to expand energy sources and address climate change and air pollution. It explores how fruit waste can be utilized as a feedstock for bioethanol production, a key renewable fuel. To conduct a thorough literature evaluation, the study used keywords including bioethanol production, bioethanol feedstocks, bioethanol from fruit wastes and bioethanol production technology to search for published studies in databases including Google Scholar, Science Direct, Springer Link, Web of Science, and Scopus. 150 articles were identified; however, 113 articles met the relevance criteria for inclusion in the present study. This study examines the methods for converting agricultural and fruit waste into bioethanol, along with the environmental and economic benefits, such as blending it with gasoline for use as vehicle fuel. This process boosts gasoline's octane rating, enhances fuel quality, lowers production costs, and reduces exhaust emissions. Besides, the present study assesses global bioethanol production and summarizes the findings from various studies on fruit wastes generation, potentiality of fruit wastes, bioethanol production and properties, potentiality of bioethanol as an energy source, bioethanol production process, parameters affecting optimal bioethanol production during microbial fermentation. It is suggested that attention be given to fruit wastes considering the cost and conditions to improve bioethanol yields through fermentation processes.
当前的审查具有重要意义,因为它与全球扩大能源来源、应对气候变化和空气污染的努力相一致。它探讨了如何利用水果废料作为生物乙醇生产的原料,这是一种关键的可再生燃料。本研究采用生物乙醇生产、生物乙醇原料、水果废弃物生物乙醇、生物乙醇生产技术等关键词,在谷歌Scholar、Science Direct、施普林格Link、Web of Science、Scopus等数据库中检索已发表论文,共检索到150篇;然而,有113篇文章符合纳入本研究的相关标准。本研究考察了将农业和水果废弃物转化为生物乙醇的方法,以及其环境和经济效益,例如将其与汽油混合用作汽车燃料。这个过程提高了汽油的辛烷值,提高了燃料质量,降低了生产成本,减少了废气排放。此外,本研究对全球生物乙醇生产进行了评估,并总结了各种研究的结果,包括水果废弃物的产生、水果废弃物的潜力、生物乙醇的生产和性质、生物乙醇作为能源的潜力、生物乙醇的生产工艺、微生物发酵过程中影响最佳生物乙醇生产的参数。考虑到成本和发酵工艺提高生物乙醇产量的条件,建议关注水果废弃物。

India is on its path to decarbonise the industrial sector for achieving climate change goals. Under National Mission for Enhanced Energy Efficiency India is implementing target-oriented, market-driven scheme since 2012 to cut energy intensity in key industrial sectors. This study examined the energy efficiency changes in forty-three Iron and Steel industries using the decomposed Malmquist Productivity Index and found only 2.9 % improvement in pure technical efficiency between 2009 and 2019. Additionally, if the energy intensity targets are met by 2024–25, further improvement of at least 4.9 % in technical efficiency is anticipated since 2009. Therefore, energy efficiency improvement in the sector found is slow during the decade and the energy intensity of the Iron and Steel industries has remained largely unchanged. The schemes aimed at enhancing energy efficiency have had little to no effect on improving energy efficiency within these industries. Also, the mean technical efficiency of forty-three Iron and Steel industries evaluated as 79.6 %, indicating the potential for a 20 % reduction in energy intensity. Now, under Indian Carbon Market the framework has been set for industries to migrate to Carbon Credit Trading Scheme. Therefore, the factors influencing the poor pace of energy efficiency improvements must be addressed under new framework.
印度正在为实现气候变化目标而使工业部门脱碳。根据国家提高能源效率使命,印度自2012年以来一直在实施以目标为导向的市场驱动计划,以降低关键工业部门的能源强度。本研究使用分解的马姆奎斯特生产率指数(Malmquist Productivity Index)对43个钢铁行业的能源效率变化进行了调查,发现2009年至2019年间,纯技术效率仅提高了2.9%。此外,如果能源强度目标在2024-25年达到,预计自2009年以来技术效率将进一步提高至少4.9%。因此,在这十年中,该部门的能源效率改善缓慢,钢铁工业的能源强度基本保持不变。旨在提高能源效率的计划对提高这些行业的能源效率几乎没有效果。此外,43个钢铁行业的平均技术效率评估为79.6%,表明能源强度降低20%的潜力。现在,在印度碳市场下,已经为工业迁移到碳信用交易计划建立了框架。因此,必须在新的框架下解决影响能效改善步伐缓慢的因素。

The rapid accumulation of end-of-life tires, driven by global vehicle use, presents severe environmental challenges. Each year, approximately 3 billion tires are produced globally, with 800 million reaching end-of-life, of which 41% are landfilled without material or energy recovery. Pyrolysis has emerged as a sustainable solution, converting waste tires into valuable by-products, including pyrolysis oil, gas, and recovered carbon black (rCB). This bibliometric review analyzes 1,431 publications (2000–2024) sourced from Scopus to map research trends, advancements, and gaps in tire pyrolysis. Three primary research hotspots are identified: (1) co-pyrolysis, emphasizing feedstock optimization and microwave-assisted methods to enhance efficiency and product quality, (2) pyrolysis oil, addressing challenges in upgrading for industrial use, and (3) recovered carbon black (rCB), focusing on advanced demineralization and activation techniques to improve its properties. Key challenges identified include feedstock variability, catalytic system optimization, and process scalability. This review provides insights and a strategic framework for advancing tire pyrolysis, fostering sustainable practices, and driving innovation across energy, materials, and environmental applications.

The push to decarbonize the energy sector by incorporating renewable sources is increasing the complexity of power plant operations. One potential solution is to digitize power plants through digital twin (DT) technology, which can improve operational efficiencies and reduce maintenance costs. However, the application of DT in power plants remains in its early stages, with no existing implementations focused on gasification technology. This study aims to develop a comprehensive digital twin framework for a biomass gasification power plant with CO2 capture (DT-BGPP).
An overview of existing DT research in power plants and their classifications was conducted to assess the current state of the field and identify gaps. Based on this analysis, essential characteristics for the DT-BGPP framework were defined, leading to the identification of its main components. The classification revealed a common gap in mid-tier categories, with most available power plant Dts lacking complete bidirectional data flow with their physical counterparts. The key components of DT-BGPP include a high-order science-informed dynamic model, a data-driven model, actual data, pre-executed localized simulations, and a system genome.
Recommendations for advancing the proposed DT-BGPP include establishing connections between all framework components to achieve a fully integrated digital twin for a biomass gasification power plant with CO2 capture.
通过引入可再生能源来推动能源部门脱碳的努力增加了发电厂运营的复杂性。一个潜在的解决方案是通过数字孪生(DT)技术将发电厂数字化,这可以提高运营效率并降低维护成本。然而,DT在发电厂的应用仍处于早期阶段,目前还没有专注于气化技术的实施。本研究旨在为具有二氧化碳捕集(DT-BGPP)的生物质气化发电厂开发一个全面的数字孪生框架。概述了电厂现有的DT研究及其分类,以评估该领域的现状并确定差距。在此基础上,定义了DT-BGPP框架的基本特征,从而确定了其主要组成部分。该分类揭示了中间类别的普遍差距,大多数可用的发电厂Dts缺乏与其物理对应的完整双向数据流。DT-BGPP的关键组成部分包括高阶科学动态模型、数据驱动模型、实际数据、预执行的局部模拟和系统基因组。推进拟议的DT-BGPP的建议包括在所有框架组件之间建立连接,以实现具有二氧化碳捕获的生物质气化发电厂的完全集成数字孪生。

Dynamic energy tariffs in combination with energy storage systems (ESS) and renewable energy sources (RES) offer manufacturers new opportunities to optimize their energy consumption. Flexible production planning empowers decision-makers not only to minimize makespan, but also to reduce energy costs and emissions. However, flexible production planning is a major challenge due to the fact that scheduling decisions affect energy demand, whose costs and emissions depend on energy procurement decisions. In Operations Research, the Green Flexible Job Shop Scheduling Problem (FJSP) addresses production planning decisions incorporating resource, environmental, and economic objectives. The Energy Procurement Problem (EPP) aims to efficiently acquire energy resources. In the literature, existing approaches for energy-aware scheduling neglect to procure energy from sources such as an uncertain dynamic energy market, RES, and ESS. We aim to close this research gap and propose a two-level approach based on a memetic Non-dominated Sorting Genetic Algorithm (NSGA-III) and linear programming with the goal of minimizing the makespan, energy costs, and emissions of a schedule, incorporating dynamic energy prices and emissions, RES, and ESS. We evaluate the approach in computational experiments using FJSP benchmark instances from the literature as part of a rolling horizon approach with real energy market data. We investigate the impact of RES and ESS by presenting estimated Pareto fronts, showing potential savings in energy cost and carbon emissions.
动态能源关税与储能系统(ESS)和可再生能源(RES)相结合,为制造商提供了优化能源消耗的新机会。灵活的生产计划不仅使决策者能够最大限度地缩短完工时间,而且还能降低能源成本和排放。然而,灵活的生产计划是一个主要挑战,因为调度决策会影响能源需求,而能源需求的成本和排放取决于能源采购决策。在运筹学中,绿色柔性作业车间调度问题(FJSP)解决了结合资源、环境和经济目标的生产计划决策。能源采购问题(EPP)旨在有效地获取能源资源。在文献中,现有的能源感知调度方法忽略了从不确定的动态能源市场、RES和ESS中获取能源。为了缩小这一研究差距,我们提出了一种基于模因非支配排序遗传算法(NSGA-III)和线性规划的两级方法,其目标是将动态能源价格和排放、RES和ESS结合起来,使计划的完工时间、能源成本和排放最小化。我们在计算实验中使用文献中的FJSP基准实例来评估该方法,作为具有真实能源市场数据的滚动地平线方法的一部分。我们通过提出估计的帕累托前沿来研究RES和ESS的影响,显示了能源成本和碳排放的潜在节约。
