Water can be resupplied to the International Space Station (ISS), but for missions outside Low Earth Orbit (LEO), it is almost impossible. Even after 50 years of research, the existing Urine Processor Assembly (UPA) and Water Processor Assembly (WPA) continue to be used on the ISS for water recovery at a suboptimal rate. There is a need to improve the existing system’s efficiency, adapt it to suit the needs of long-range missions, or develop new technology. This review examines the UPA and WPA systems, highlighting their roles, efficiency, and the need for further modification. Membrane-based technologies, including Forward Osmosis (FO) and Membrane Distillation (MD), as well as emerging hybrid technologies such as integrated FO-MD and the Photocatalytic Membrane Reactor (PMR), have been discussed. Special attention has been given to brine treatment technologies, such as the Forward Osmosis Brine Dryer (FOBD), Ionomer Water Processor (IWP), Capillary Brine Residual in Containment (CapiBRIC), and Brine Evaporation Bag (BEB), which various space agencies have identified as potential alternatives. Technological advancements in developing a closed-loop biological life support system, Micro-Ecological Life Support System Alternative (MELiSSA) are also discussed. These technologies can be used as a standalone system or integrated with other treatment methods for water recycling. The review offers a critical evaluation of current water recycling systems and examines innovative technologies that can be integrated to enhance system reliability in space exploration missions.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"14 2","pages":"Article 121355"},"PeriodicalIF":7.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146024765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the large volume of end-of-life LIBs generates substantial amounts of retired graphite, which not only poses potential environmental risks but also raises challenges for strategic resource security, making its standardized management an urgent issue. This review focuses on the recycling and reuse of graphite from retired LIBs, systematically summarizing the core stages of the recovery process, including battery disassembly, graphite separation and purification, and strategies for restoring the performance of regenerated graphite. Key technologies, such as mechanical disassembly, hydrometallurgical/pyrometallurgical treatment, acid leaching, graphitization, flash joule heating, microwave treatment, and carbon coating, are analyzed in terms of their advantages and limitations, with discussion on effective approaches to enhance the electrochemical performance, structural repair, and cycling stability of regenerated graphite. Despite significant progress in graphite recycling and regeneration, several research gaps remain, such as the unclear quantitative relationship between defect repair efficiency and energy input during regeneration, which hinders precise process control, and the heterogeneity of retired graphite from different sources, which limits the adaptability of existing technologies. Furthermore, the industrial-scale application of regeneration technologies and the precise regeneration of various types of graphite are expected to be key research directions. These advances will facilitate the closed-loop utilization of LIBs materials, ensure strategic resource supply, and contribute to the development of sustainable energy.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"14 2","pages":"Article 121412"},"PeriodicalIF":7.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146074882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Key inhibitors including cyanides, phenols, thiocyanates, ammonia, PAHs, heavy metals, and nitrogen-containing heterocycles are evaluated across four major biological treatment systems: aerobic oxidation, anaerobic digestion, partial nitritation, and anammox. Special emphasis is placed on synergistic toxicities (e.g., phenol–ammonia interactions) and on the acute sensitivity of nitrifying and anammox bacteria to heterocyclic compounds such as quinoline and pyridine.

Three VF-CW systems were fabricated, of which two were planted with <em>Canna indica</em> (VF-CWC)<em>, Typha angustifolia</em> (VF-CWT)<em>,</em> and one with no plant as a control (VF-CWN). Among these three, VF-CWC demonstrated ∼100 % of MB and 97.24 ± 1.50 % of COD removal after 24 h at pH 7.8, which was 1.1 and 1.2 times higher in MB (90.50 ± 1.30 %) and COD removal (80.35 ± 1.60 %) than VF-CWT. In contrast, VF-CWN (control) showed comparable removal of 85.10 ± 1.50 % of MB and 73.93 ± 1.40 % of COD operating under similar conditions. However, the effluent of the sole VW-CWC contained 28,900 colony-forming units (CFU)/mL of <em>E. coli</em> at a 10² dilution; further treating the effluent with the UV/HOCl system effectively eliminates all <em>E. coli</em>. The assessment of growth parameters of <em>Canna indica</em> and <em>Typha angustifolia in</em> VF-CWC and VF-CWT demonstrated a higher growth rate and adaptability of <em>Canna indica</em> in the substrate and wastewater. The degradation of MB in VF-CWC + UV/HOCl involves ring opening, oxidation, and ring contraction, ultimately converting it into CO₂ and H₂O. The cost to treat per m³ of MB-containing wastewater by the integrated system was observed to be 0.331 $/m³ (Rs. 29.65 per m³). The OpenLCA results revealed that the combined VF-CWC + UV/HOCl had the least impact on resource depletion, ecology, and human health.
