The use of carbonated mineral products in cement production reduces carbon emissions and enhances durability. This study evaluated the environmental sustainability of using mineral carbonated biomass fly ash (BFA) as a partial cement replacement in European cement production. Laboratory-scale and simulated large-scale scenarios were analysed. Incorporating 20% mineral carbonated BFA showed potential for a 33% reduction in the annual Global Warming Potential (GWP) of cement products. Energy consumption factors, such as ball milling and mineral carbonation processes, were evaluated using a machine learning model and comminution flow sheet model simulations. The machine learning model predicted CO₂ absorption and energy requirements for mineral carbonation, showing greater efficiency in large-scale scenarios. Life cycle assessments consistently revealed GWP reductions for OPC-BFA mixtures, with additional emissions reductions when incorporating flow sheet modelling and machine learning data. However, the study's limitations include simplified CO₂ flue gas treatment, use of the mean EU electricity mix, exclusion of transportation impacts, and reliance on simulation data. Additionally, the cement mix exhibited reduced compressive strength. This study highlights the potential of mineral carbonated BFA to reduce cement production's environmental impact while emphasising the need for balanced optimisation between sustainability and material performance.

在水泥生产中使用碳化矿物产品可减少碳排放并提高耐久性。本研究评估了在欧洲水泥生产中使用碳化矿物生物质粉煤灰（BFA）作为部分水泥替代品的环境可持续性。对实验室规模和模拟大规模方案进行了分析。结果表明，掺入 20% 的矿物碳化生物质粉煤灰可使水泥产品的年全球升温潜能值 (GWP) 降低 33%。使用机器学习模型和粉碎流程模型模拟评估了球磨和矿物碳化工艺等能耗因素。机器学习模型预测了矿物碳化过程中的二氧化碳吸收量和能源需求，在大规模应用场景中显示出更高的效率。生命周期评估一致显示，OPC-BFA 混合物的全球升温潜能值降低了，在结合流片建模和机器学习数据后，排放减少了更多。然而，该研究的局限性包括简化了二氧化碳烟气处理、使用了欧盟平均电力组合、排除了运输影响以及依赖模拟数据。此外，水泥混合物的抗压强度也有所降低。这项研究强调了矿物碳化反式脂肪酸在减少水泥生产对环境影响方面的潜力，同时也强调了在可持续发展和材料性能之间进行平衡优化的必要性。

Microbial oils (MOs) are lipids produced by oleaginous microorganisms, which constitute an alternative to vegetable and fossil-derived oils. They can be produced from organic waste by coupling acidogenic fermentation (AF) with oleaginous fermentation (OF). This study addresses a life cycle sustainability assessment (LCSA) of MO produced from the organic fraction of municipal solid waste. First, a system was modelled using simulation tools. This model combines AF for the production of volatile fatty acids from organic waste, OF for the production of lipid-rich yeasts, and MO extraction. LCSA results indicate the need for improvements in the disruption of yeasts and the overall efficiency of the system. Particularly, slightly acidified thermolysis turned out to involve excessively high steam requirements. An enhanced sustainability performance could be achieved by exploring alternative disruption methods or alternative sources of energy for the production of steam such as biogas from the valorisation of the sludges produced in the system.

微生物油（MOs）是由含油微生物产生的脂质，是植物油和化石油的替代品。微生物油可以通过产酸发酵（AF）和含油发酵（OF）相结合的方法从有机废物中生产出来。本研究针对从城市固体废弃物的有机部分生产出的 MO 进行了生命周期可持续性评估（LCSA）。首先，使用模拟工具对系统进行建模。该模型结合了从有机废物中生产挥发性脂肪酸的 AF、生产富含脂质的酵母的 OF 以及 MO 的提取。LCSA 的结果表明，需要改进酵母的破坏和系统的整体效率。特别是微酸化热解过程需要过多的蒸汽。通过探索其他破坏方法或生产蒸汽的替代能源，如利用系统产生的沼渣产生的沼气，可以提高可持续性性能。

Wastewater treatment plants play a vital role in resource recovery, particularly through biogas production, a key renewable energy source. Beyond biogas, the digestate from anaerobic digestion is rich in nutrients like ammonia. This study explored the feasibility of recovering ammonia from sewage sludge digestate using air stripping. The process was modeled using Aspen Plus® software, utilizing real data from As-Samra WWTP in Jordan. Various operational parameters, such as digestate feed flow, air flow rate, temperature, and pressure, were analyzed to optimize ammonia recovery. The results showed that with a feed flow rate between 10,000 and 30,000 kg/hr, ammonia recovery reached 85%, with production exceeding 100 kg/hr, where the effect of the flow rate appears mostly at elevated feeding temperatures. Increased air flow rates significantly boosted recovery, achieving 90% efficiency at 60 °C with 50,000 kg/h as air flow. Flashing pressure peaked at 1.5 bar, with 85% efficiency at 95 °C, while higher pressures yielded diminishing returns, stabilizing production around 106 kg/hr. The NaOH feed rate also influenced output, rising from 100 kg/hr at a 50 kg/hr feed rate to 107 kg/hr at 750 kg/hr, with recovery efficiency exceeding 85%. The economic analysis showed that the project had a payback period of 6.07 years, reflecting a reasonable recovery of the initial investment. The net present value was 122,924 USD over 15 years, with 8% amortization rate, indicating that the project created value beyond the initial cost. The internal rate of return was 14.23%, surpassing the discount rate and highlighting the project's financial attractiveness.

污水处理厂在资源回收方面发挥着至关重要的作用，特别是通过生产沼气这种重要的可再生能源。除沼气外，厌氧消化产生的沼渣还富含氨等营养物质。本研究探讨了利用空气剥离从污水污泥消化液中回收氨的可行性。利用约旦 As-Samra 污水处理厂的真实数据，使用 Aspen Plus® 软件对该工艺进行了建模。分析了沼渣进料流量、空气流速、温度和压力等各种运行参数，以优化氨回收。结果表明，进料流量在 10,000 至 30,000 公斤/小时之间时，氨回收率达到 85%，产量超过 100 公斤/小时，其中流量的影响主要体现在进料温度升高时。增加空气流量可显著提高回收率，在 60 °C 条件下，空气流量为 50,000 公斤/小时时，回收率达到 90%。闪蒸压力在 1.5 巴时达到峰值，95 °C时的效率为 85%，而更高的压力会导致收益递减，使产量稳定在 106 公斤/小时左右。NaOH 进料率也影响产量，从 50 kg/hr 进料率时的 100 kg/hr，上升到 750 kg/hr 时的 107 kg/hr，回收效率超过 85%。经济分析表明，该项目的投资回收期为 6.07 年，合理地收回了初始投资。15 年的净现值为 122,924 美元，摊销率为 8%，表明该项目创造的价值超出了初始成本。内部收益率为 14.23%，超过了贴现率，凸显了项目的财务吸引力。

Bleached eucalyptus kraft (BEK) pulp dominates global pulp production, yet the environmental impacts of its bleaching sequences in Brazil are not fully explored. Addressing this gap, we conducted a comparative life cycle assessment (LCA) of three bleaching sequences: conventional elemental chlorine-free (ECF), ECF with oxygen delignification, and ECF with oxygen delignification plus acid washing. We estimated the average global warming potential (GWP) for BEK delivered to the U.S. and examined how forest carbon cycle (FCC) elements, specifically biogenic GWP (GWPbio) and potential soil organic carbon (SOC) sequestration, influence GWP outcomes. Results show that the ECF sequence with oxygen delignification and acid washing reduces GWP by 11% and outperforms conventional ECF in 10 out of 11 environmental impact categories. The average GWP for Brazilian BEK delivered to the U.S. is 576 kg CO₂-eq/ton. Sensitivity analyses demonstrate that adding GWPbio increases GWP by 18%, whereas accounting for potential SOC sequestration reduces it by 39%. These findings highlight the necessity of optimizing bleaching processes and developing a standardized BEK LCA model for comparing the environmental impact of different fibers. This work sets a precedent for integrating FCC elements into LCAs and underscores the potential of SOC sequestration in mitigating climate change impacts.

漂白桉树牛皮纸浆（BEK）在全球纸浆生产中占主导地位，但其在巴西的漂白过程对环境的影响尚未得到充分探讨。针对这一空白，我们对三种漂白程序进行了生命周期比较评估（LCA）：传统的无元素氯漂白（ECF）、含氧脱木素漂白（ECF）和含氧脱木素加酸洗漂白（ECF）。我们估算了运往美国的 BEK 的平均全球升温潜能值 (GWP)，并研究了森林碳循环 (FCC) 要素，特别是生物源全球升温潜能值 (GWPbio) 和潜在的土壤有机碳 (SOC) 固碳如何影响全球升温潜能值结果。结果表明，氧脱木质素和酸洗的 ECF 序列可将 GWP 降低 11%，在 11 个环境影响类别中的 10 个类别中均优于传统 ECF。运往美国的巴西 BEK 的平均全球升温潜能值为 576 千克 CO₂-eq/吨。敏感性分析表明，增加生物全球升温潜能值会使全球升温潜能值增加 18%，而考虑潜在的 SOC 固存则会使全球升温潜能值降低 39%。这些发现凸显了优化漂白工艺和开发标准化 BEK LCA 模型以比较不同纤维对环境影响的必要性。这项工作开创了将催化裂化碳元素纳入生命周期评估的先例，并强调了 SOC 固碳在减轻气候变化影响方面的潜力。

The purpose of this study is to present a novel approach of integrating Material Flow Cost Accounting (MFCA), Internet of Things (IoT) and lean management systems to improve water use efficiency and reduce costs in the beverage industry. The positive and negative product costs of water purification, syrup manufacture, concentrate mixing, and packing were analyzed. The MFCA analysis showed 78.5% positive and 21.5% negative product costs. The use of the Power BI application to display real-time positive and negative costs in each process, scenario modeling and simulation was able to promote water savings and cost reductions, as well as supporting factory team ideation for choosing one of three improvement plans: 1) RO flushing water recovery in water purification; 2) water conservation with automated pH correction at packaging warmer; or 3) wastewater treatment and reuse of the rejected RO brine. According to our two-scenario water conservation testing, an automation process could improve pH adjustment in the packaging process, while MFCA, IoT, and lean management systems could be applied to improve industrial water use efficiency, demonstrating the potential for sustainable water use. The beverage-industry case in the present study validated this approach, resulting in a 24.1% production rate increase and a 4.5% cost reduction of 71,010 THB savings per year.

本研究旨在提出一种整合物料流成本会计（MFCA）、物联网（IoT）和精益管理系统的新方法，以提高饮料行业的用水效率并降低成本。分析了水净化、糖浆生产、浓缩液混合和包装的正负产品成本。MFCA 分析显示，正产品成本占 78.5%，负产品成本占 21.5%。通过使用 Power BI 应用程序实时显示各流程的正负成本、情景建模和模拟，能够促进节水和降低成本，并支持工厂团队从三个改进方案中选择一个：1) 在水净化过程中回收反渗透冲洗水；2) 在包装加温时通过自动 pH 值校正节约用水；或 3) 废水处理和反渗透盐水的回用。根据我们的两种节水方案测试，自动化工艺可改善包装过程中的 pH 值调节，而 MFCA、物联网和精益管理系统则可用于提高工业用水效率，从而展示了可持续用水的潜力。本研究中的饮料行业案例验证了这一方法，使生产率提高了 24.1%，成本降低了 4.5%，每年节约 71,010 泰铢。

Coffee is one of the most consumed products globally, and yet its eco-efficiency is still unknown. To address this knowledge gap, this paper examines for the first time the life cycle eco-efficiency of different coffee drinks to identify the most sustainable options and opportunities for improvements in the coffee industry. Nine types of coffee are considered: espresso, latte, cappuccino, Americano, drip-filter, coffee pods, spray-dried and freeze-dried instant, and instant coffee mix. Taking a cradle-to-grave approach, the following life stages are included: coffee cultivation, production and consumption, and end-of-life valorisation of spent coffee grounds. The methodology follows the eco-efficiency ISO 14045 standard to measure the environmental efficiency of a system relative to the economic value it generates. The eco-efficiency is estimated at both the product (one serving) and sectoral (annual consumption) levels based on life cycle assessment (LCA), life cycle costing (LCC) and economic value added (VA). The results show that latte has the highest environmental impacts and LCC but it also has the highest VA at both the product and sectoral levels. Spray-dried instant coffee, on the other hand, has the lowest impacts but also the lowest VA, which makes it the least eco-efficient option. Espresso emerges as the most eco-efficient drink because it has moderate environmental impacts and high VA. Latte and coffee pods are the second most eco-efficient drinks, followed by cappuccino, Americano, and instant coffee mix. Valorising spent coffee grounds could reduce the environmental impacts, LCC and increase the VA at the sectoral level. For example, the climate change impact would be reduced by 80.5–132.1 kt CO₂ eq./yr and primary energy demand by 0.9–2.3 PJ/yr while also increasing the VA by £50.2–95 M/yr. When compared to some other food sectors, coffee is 6.4 times more eco-efficient than cheddar cheese and 5.4 times than ice cream and biscuits, respectively. The findings of this study can be used to guide businesses, consumers and policy makers in identifying more eco-efficient coffee products and improving the environmental and economic sustainability of the coffee industry.

咖啡是全球消费量最大的产品之一，但其生态效益仍不为人知。为了填补这一知识空白，本文首次研究了不同咖啡饮品的生命周期生态效益，以确定咖啡行业中最具可持续性的选择和改进机会。本文研究了九种咖啡：意式浓缩咖啡、拿铁咖啡、卡布奇诺咖啡、美式咖啡、滴滤式咖啡、咖啡豆荚、喷雾干燥和冷冻干燥速溶咖啡以及速溶混合咖啡。采用 "从摇篮到坟墓 "的方法，包括以下生命阶段：咖啡种植、生产和消费，以及废弃咖啡渣的报废处理。该方法遵循生态效益 ISO 14045 标准，以衡量一个系统的环境效益与其产生的经济价值的关系。根据生命周期评估（LCA）、生命周期成本计算（LCC）和经济附加值（VA），从产品（一份咖啡）和行业（年消费量）两个层面对生态效益进行估算。结果表明，拿铁咖啡对环境的影响和生命周期成本最高，但在产品和行业层面的经济增值也最高。另一方面，喷雾干燥速溶咖啡对环境的影响最小，但附加值也最低，因此是生态效益最低的选择。浓缩咖啡是最具生态效益的饮品，因为它对环境的影响适中，而增值效应较高。拿铁咖啡和咖啡豆荚是生态效率第二高的饮品，其次是卡布奇诺、美式咖啡和速溶咖啡粉。对废咖啡渣进行估价可以减少对环境的影响，降低生命周期成本，增加部门层面的增值效应。例如，气候变化影响将减少 80.5-132.1 kt CO2 eq./年，一次能源需求将减少 0.9-2.3 PJ/年，同时增值价值也将增加 5020-9500 万英镑/年。与其他一些食品行业相比，咖啡的生态效益是切达奶酪的 6.4 倍，是冰淇淋和饼干的 5.4 倍。这项研究的结果可用于指导企业、消费者和政策制定者确定更具生态效益的咖啡产品，并改善咖啡产业的环境和经济可持续性。

This study investigates the impact of climate policy uncertainty on environmental degradation and examines the moderating role of democracy in this relationship. Utilizing annual data from 126 economies spanning the years 1996–2021, and employing dynamic least squares and fully modified ordinary least squares models, the analysis reveals a significant negative relationship between climate policy uncertainty and environmental degradation. The findings indicate that higher uncertainty in climate policies is associated with reduced environmental degradation, suggesting that uncertainty in climate policies can drive cautious and ecologically conscious behaviors. Additionally, the study finds that democracy amplifies this negative relationship, implying that democratic environments enhance the effectiveness of climate policies in reducing environmental degradation which is attributed to greater transparency, accountability, public participation, and policy stability inherent in democratic systems. The study offers valuable practical implications for policymakers by highlighting how political and economic systems can influence environmental outcomes amid climate change.

本研究探讨了气候政策不确定性对环境退化的影响，并研究了民主在这一关系中的调节作用。利用 1996-2021 年间 126 个经济体的年度数据，并采用动态最小二乘法和完全修正的普通最小二乘法模型，分析表明气候政策不确定性与环境退化之间存在显著的负相关关系。研究结果表明，气候政策的不确定性越高，环境退化的程度就越低，这表明气候政策的不确定性可以推动谨慎和具有生态意识的行为。此外，研究还发现民主会放大这种负相关关系，这意味着民主环境会提高气候政策在减少环境退化方面的有效性，而这要归功于民主制度所固有的更高透明度、问责制、公众参与和政策稳定性。这项研究强调了政治和经济制度如何在气候变化中影响环境结果，从而为政策制定者提供了宝贵的现实意义。

The unbound usage of plastic products in modern society has brought convenience and poses significant environmental challenges. Recycling Shops (RS) are vital in mitigating plastic waste problems in urban waste management. During the recycling process, RS generates non-recyclable plastics that demand scientific solutions for its management. This study conducted material flow analysis (MFA) to estimate the yearly recycled plastic waste in the RSs of Khulna City. Subsequently, a life cycle assessment (LCA) was performed to explore the suitable management facilities for non-recyclable plastics. The results highlighted the contribution of the informal plastic recycling sector to the city's waste management system by recycling 6324 tons of plastic waste per year. Polypropylene (PP) and Polyethylene (PE) were the most abundant polymers among the recycling plastics in RS. The LCA results revealed that among the five considered cases, Open Burning showed the maximum impact on the environment while Sanitary Landfill exhibited the lowest environmental impact across eighteen impact categories. The sanitary landfilling of non-recyclable plastics was identified as an environmentally friendly approach for managing non-recyclable plastics. This study addressed the urgency for appropriately managing non-recyclable plastics to protect the human and environment from plastic pollution in Bangladesh including recommendations for improving current practices.

在现代社会中，塑料产品的无限制使用在给人们带来便利的同时，也给环境带来了巨大的挑战。在城市废物管理中，回收店（RS）对缓解塑料废物问题至关重要。在回收过程中，RS 会产生不可回收的塑料，需要科学的管理解决方案。本研究进行了材料流分析（MFA），以估算库尔纳市 RS 每年回收的塑料垃圾。随后，进行了生命周期评估（LCA），以探索适合不可回收塑料的管理设施。结果表明，非正规塑料回收部门每年回收 6324 吨塑料废物，为该市的废物管理系统做出了贡献。在 RS 回收的塑料中，聚丙烯（PP）和聚乙烯（PE）是最多的聚合物。生命周期评估结果显示，在考虑的五种情况中，露天焚烧对环境的影响最大，而卫生填埋对环境的影响在十八种影响类别中最低。不可回收塑料的卫生填埋被认为是管理不可回收塑料的环保方法。本研究探讨了孟加拉国适当管理不可回收塑料以保护人类和环境免受塑料污染的紧迫性，包括改进当前做法的建议。

In the face of the high competitiveness in the marketplace, many companies have sought ways to differentiate themselves from others by improving the quality of their products and services, reducing the environmental impact, and ensuring employee safety. In this context, many companies implemented some management systems such as ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety Management) to improve their performance. The International Organization for Standardization (ISO) created in 2012 a high-level structure (Annex SL) that serves as the basis for the development and integration of these Certifiable Management systems (CMSs), making them more compatible and effective. However, many companies do not have sufficient expertise about the latest versions of ISO 9001 and ISO 14001 and about the publication of ISO 45001 based on the structure proposed by Annex SL, bringing difficulties for their Integrated Management Systems (IMS). The objective of this work is to propose recommendations that direct companies to adapt their IMSs to the modifications arising from Annex SL. To develop this study, four case studies were made in Brazilian industrial companies with the following data collection instruments (semi-structured interviews, on-site observation, and document analysis). Our case studies were carried out in large companies because these types of organizations generally have more than two management systems implemented, and our article focuses on systems integration. In addition, these companies develop several interesting solutions that can serve as benchmarking for small and medium-sized companies. With this study it was possible to develop guidelines related to greater emphasis on the analysis of the organizational context; the importance of promoting a culture of integration; the need for leadership responsible for the integration of CMSs, etc. The main scientific contribution of this work was to deepen and update the theory about certifiable management systems and IMS according to the results obtained from empirical studies. The main applied contribution of this study is to generate a competitive advantage for the company over its competitors by providing leaders with management solutions that make it possible to implement or improve IMS based on the modifications resulting from Annex SL.

面对激烈的市场竞争，许多公司都在想方设法通过提高产品和服务质量、减少对环境的影响以及确保员工安全来与其他公司区分开来。在这种情况下，许多公司实施了一些管理体系，如 ISO 9001（质量管理）、ISO 14001（环境管理）和 ISO 45001（职业健康与安全管理），以提高其绩效。国际标准化组织（ISO）于 2012 年创建了一个高级结构（附件 SL），作为开发和整合这些可认证管理体系（CMS）的基础，使其更具兼容性和有效性。然而，许多公司对 ISO 9001 和 ISO 14001 的最新版本以及基于附件 SL 所建议结构的 ISO 45001 的发布缺乏足够的专业知识，这给他们的综合管理系统（IMS）带来了困难。这项工作的目的是提出建议，指导企业根据附件 SL 的修改调整其 IMS。为了开展这项研究，我们通过以下数据收集工具（半结构式访谈、现场观察和文件分析）对巴西的工业企业进行了四项案例研究。我们的案例研究是在大公司中进行的，因为这些类型的组织一般都实施了两个以上的管理系统，而我们的文章侧重于系统集成。此外，这些公司开发了一些有趣的解决方案，可以作为中小型公司的基准。通过这项研究，我们有可能制定出一些指导方针，涉及更加重视对组织环境的分析、促进整合文化的重要性、负责整合内容管理系统的领导层的必要性等。这项工作在科学方面的主要贡献是，根据实证研究的结果，深化和更新了关于可认证管理系统和综合管理系统的理论。本研究在应用方面的主要贡献是，通过向领导者提供管理解决方案，使其有可能根据附件 SL 的修改意见实施或改进 IMS，从而为公司创造超越竞争对手的竞争优势。

Reusable glass bottles are experiencing a resurgence, driven notably by societal concerns and regulations. While single-use glass bottles generally have higher environmental footprint compared to plastic bottles, reusable systems could reduce both impacts related to single-use (e.g., climate change, energy consumption) and plastics (e.g., microplastic pollution). The environmental benefits of reusable bottles can vary across systems and this can be overlooked by stakeholders who rely on generic results for communication and a limited number of parameters to design their systems. This study addresses this gap by developing a systematic analysis of the variability of life cycle assessment results, within the specific case study of a new beverage. As a result, a list of key parameters to consider for the specific case study is set, enabling to propose targeted mitigation strategies. The commonly used generic key parameters are complemented with context-specific key parameters, empowering stakeholders to develop efficient systems and communicate their environmental performance accurately. Different configurations are likely to be influenced by other key parameters, and require specific mitigation strategies. In this perspective, stakeholders need assistance in: (1) designing context-specific strategies, and (2) translating – complex and plural – life cycle assessment results into actionable decisions.

在社会关注和法规的推动下，可重复使用的玻璃瓶正在重新兴起。虽然与塑料瓶相比，一次性使用的玻璃瓶通常对环境的影响更大，但可重复使用的系统可以减少与一次性使用（如气候变化、能源消耗）和塑料（如微塑料污染）相关的影响。可重复使用瓶在不同系统中的环境效益可能会有所不同，这一点可能会被利益相关者所忽视，因为他们依赖于通用的结果来进行交流，并依赖于有限的参数来设计他们的系统。本研究针对这一缺陷，在新饮料的具体案例研究中，对生命周期评估结果的可变性进行了系统分析。因此，为具体案例研究制定了一份需要考虑的关键参数清单，从而能够提出有针对性的缓解策略。常用的通用关键参数与特定环境下的关键参数相辅相成，使利益相关者能够开发高效的系统，并准确传达其环境绩效。不同的配置可能会受到其他关键参数的影响，因此需要特定的缓解策略。从这个角度来看，利益相关者需要在以下方面得到帮助：（1）设计针对具体情况的策略；（2）将复杂而多元的生命周期评估结果转化为可操作的决策。
