Unfortunately, the rapid development of such technology is hindered by technical issues such as sluggish diffusion of Zn²⁺ within the host material. In this work we demonstrate that is possible to use a non-aqueous hybrid Zn/K battery circumventing the Zn²⁺ insertion effects into two host structures by using monovalent ions. For this approach two different structures with different alkali earth metals (K and Na) are tested as the cubic (N-MF: Na_1.9Mn[Fe(CN)₆]_0.95·3.9H₂O) and monoclinic (K-MF: K_1.9Mn[Fe(CN)₆]_0.94·0.61H₂O) PBAs. Intriguing phase changes and voltage of the reactions are disclosed. A single voltage plateau occurred at 2 V in charge and 1 V on discharge for K-MF. Voltage plateaux between 2.05 and 2.65 and 3.05 V on charge, and 1.2–0.95 V on discharge for N-MF are observed. Two active redox centres Fe^2+/3+ and Mn^2+/3+ trigger a multi-electron reaction with 141.2 (K-MF) and 117.7 mA h g⁻¹ (N-MF). Eventually, a wide electrochemical voltage can be used for N-MF cathode to 3.25 V (vs. Zn²⁺/Zn) with a characteristic phase transformation from cubic to monoclinic on cycling, reporting data to enhance the voltage and energy density.

For companies that produce automotive products, this can be an issue, due to the current need to comply with EU sustainable goals. The environmental impact of the GFRP, that includes PBT-GF30, increases when products incorporate other material, such as metallic screws. When the products come out defective from the manufacturing, the complete segregation between metal and plastic is complex. Therefore, the product EoL is usually the landfill and the lack of their recyclability raised an environmental concern. To overcome this environmental issue, this study pointed out Cryogenic Treatment (CT) as a technique to fragilize the GFRP, improving the recycling process in two ways: materials segregation and decreased energy for plastic's shredding. To conduct the analysis, PBT-GF30 samples, with and without screws, were subjected to CT and impact tests and afterwards a mechanical characterization was performed, confirming the variation of tensile strength. To complement the study, LCA and LCC was conducted for three scenarios of disposal of the defective parts – landfill; mechanical recycling; and CT before mechanical recycling, in order to characterize the environmental impact of the proposed solution compared to the current one, landfill. Results highlight that CT and impact lowered the PBT-GF30 stress at break by 30 %, requiring less energy by the same amount to break the material in the shredding process. The analysis identified the landfill scenario (baseline) as having the highest environmental impact, primarily due to the absence of material recovery, which increases the demand for raw materials, increasing extraction-related impacts. In contrast, recycling methods significantly reduced these burdens. CT before mechanical recycling, for instance, demonstrated a potential 30 % reduction in environmental impacts by reintegrating recycled materials into production processes, highlighting its potential to enhance sustainability. However, the high cost associated with liquid nitrogen production could be a limitation. Nonetheless, CT before mechanical recycling offers approximately 30 % lower costs than the baseline when viewed through a circular economy perspective, presenting a balanced approach to improving environmental and economic outcomes.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"44 ","pages":"Article e01298"},"PeriodicalIF":8.6,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143591892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To respond to this need, the environmental impact of life cycle intervention strategies of reinforced concrete structures to restore and prevent corrosion damage is analysed through a life cycle assessment (LCA). First, the dominant midpoint impact categories, related to these interventions, are identified as (1) carcinogenic human toxicity, (2) global warming potential (3) fine particulate matter formation, (4) freshwater ecotoxicity, (5) non-carcinogenic human toxicity and (6) marine ecotoxicity. Secondly, a comprehensive assessment is performed for reference flow activities related to the EN1504–9 principles in order to get more insight into this data before case dependencies are applied. Based on this, the hotspots per category and even per activity could be determined. In general, the production and gross End-of-Life (EoL)-phase are the important life cycle phases. Finally, the activities and principles are combined to achieve actual intervention strategies applied on a case study of a reinforced concrete bridge. The outcomes show the dominance of carcinogenic human toxicity resulting in a high impact for demolishing and rebuilding. Although this scenario scores well for other midpoints, alternative interventions like impressed current cathodic protection score well in general. So, the interventions patch repair, conventional repair, galvanic cathodic protection, chloride extraction and realkalisation perform less well on average. Nevertheless, for specific midpoints or service life extensions they could still have a lower impact, like patch repair for a 20-year service life. In addition, the production and gross EoL-phase are also the most important for the case study.

Accordingly, in this study, porous carbon materials were synthesized by partially degrading the lignocellulosic fractions in cow dung through a series of processes, including NaOH pretreatment under varying conditions (concentration, time, and temperature), pre‑carbonization, and KOH activation.
