The choice of the energy storage material is equally crucial. Although metal oxides, metal sulfides, and metal phosphates exhibit high specific capacitance, activated carbon-based materials dominate the commercial market due to their environmental friendliness, abundant availability, and non-hazardous nature. Our ongoing task involves using bio-waste to prepare high-energy-density activated carbon. The material confirmation was confirmed through various characterizations such as XRD, Raman, FTIR, EDX, SEM, BET, and XPS. The electrochemical three-electrode analysis of the prepared activated carbon for various ZnCl₂ activation ratios (1:1, 1:3, 1:5) showed that the 1:3 (carbon: ZnCl₂) ratio possesses higher specific capacitance compared to the other ratios, leading to further two-electrode analysis for this sample. We have prepared a symmetric full cell, achieving 117 F/g for 1 A/g, with corresponding 37 Wh/kg energy and 757 W/kg power densities. The cyclic stability of the sample explored 90% capacitive retention over 10,000 cycles.

Consequently, demand for REEs is increasing rapidly in comparison to their supply. Recycling of REEs from end-of-life (EoL) electronic waste (e-waste) can help to mitigate the increasing gap between the demand and supply of REEs. This study reports the separation and recovery of high-purity Dy from various feedstocks such as scrap permanent magnets (SPMs), electric vehicle (EV) magnets, and mixed rare earth oxides (REOs) using an economically viable and scalable membrane solvent extraction (MSX) process. First, the optimized conditions (organic phase composition and feed solution acid concentration) for the separation of Dy from light REEs such as neodymium (Nd) and praseodymium (Pr) were evaluated using liquid–liquid extraction. Thereafter, a multistage MSX process was developed to separate high purity (&gt;99.5 wt %) Dy from Nd and Pr using Cyanex 572, a cationic extractant. Using feedstocks with varying initial compositions, the MSX process obtained 100% pure Dy with 63–96% Dy recovery in three to six stages with a maximum extraction rate of 2.9 g m^–2 h^–1. Purity of the recovered Dy was confirmed via additional characterization such as scanning electron microscopy, energy dispersive X-ray spectroscopy, and X-ray diffraction.

Despite a few reports suggesting improved performance of two-stage AD with biochar addition, the existing reports provide limited insights into the role of biochar in microbial dynamics and its mechanisms of enhancement. This study investigated the impact of different biochar dosages (5, 15, and 25 g/L) on the two-stage mesophilic AD of food waste, focusing on biogas production, dynamics of volatile fatty acids (VFAs), organic removal, and microbial community diversity and structure. During the first stage, cumulative hydrogen (H₂) production increased by 23−30% in biochar-amended reactors, while in the methanogenesis stage, cumulative methane (CH₄) yields increased by 31−41%. However, no statisticallly significant differences (<em>p</em> &gt; 0.05) were obeserved among the different biochar dosages, suggesting that 5 g/L would be the optimum dosage for both stages. Biochar promoted the accumulation of VFAs during the first stage while enhancing VFA conversion to methane in the second stage, with 5 g/L of biochar exhibiting the lowest VFA accumulation. In addition to increased microbial diversity and richness, 5 g/L of biochar also selectively enriched various fast-growing hydrolytic/fermentative taxa in the first stage while significantly stimulating syntrophic fatty-acid degraders (<em>Syntrophomonas</em>) and metabolically versatile methanogens (<em>Methanosarcina</em>) in the second stage, indicating improved syntrophic cooperation and potential facilitation of direct interspecies electron transfer (DIET).

A mechanochemical recycling process was demonstrated in three steps in an internal mixer: partial aminolysis, cross-linking, and foaming. Partial aminolysis was successfully demonstrated using a cycloaliphatic diamine and yielded a melt-processable PU with gel content (GC) of 54.4% using as low as 6 wt % of diamine from a pristine PU with 94.1% GC. The material was then efficiently cross-linked by blending it with a blocked isocyanate based on 4,4′-methylenebis (phenyl isocyanate) at 100 °C and then triggering its reactivity at 160 °C to yield a material with GC of 84.7%. The blocked isocyanate unblocking kinetics were assessed using rheometry and revealed partial reactivity even at 100 °C. The mechanical properties of the cross-linked recycled PU exhibited significantly improved properties as a consequence of network reformation. Finally, the concomitant use of a chemical blowing agent with blocked isocyanate allowed to yield a cross-linked recycled PU foam as a final step of mechanical processing. The strong reactivity of the blocked isocyanate appeared to limit the foaming marginally. Finally, the cross-linking and foaming process was performed successfully in one step in a single-screw extruder.

According to experimental results, it was supposed that, with the pyrolytic time increasing, the reduction reaction reached dynamic equilibrium leading to a Cu−Co−La decreasing sequence of the amount and strength of acidity, which led to the relative content of organosilicon compounds in bio-oil decreasing with Ni−Cu/HZSM-5 (60.81%), Ni−Co/HZSM-5 (43.42%), and Ni−La/HZSM-5 (42.11%) and that of long-chain carboxylic acid and ester increasing with Ni−Cu/HZMS-5 (4.83%), Ni−Co/HZSM-5 (8.35%), and Ni−La/HZSM-5 (12.93%). The weaker the strong acidity, the more phenolic compounds generated. As regards Ni−Co/HZSM-5, apart from its intensity of acidity, the relatively uniform and biggest pore size might also be responsible for its strongest capability of generating aromatic compounds. In turn, for Ni−Cu/HZSM-5, its low utilization rate of active sites might be related to its weakest capability of producing phenolic compounds. Ni−Cu/HZSM-5 possessed moderately strong abilities to promote the catalytic reforming of methane with carbon dioxide or water vapor with Ni and Cu grippers; Cu inveigled electrons and transferred to Ni creating Ni^δδδ− (the atomically dispersed electron-rich nickel species). Thus, the intermediates easily captured electrons from Ni^δδδ− to release more H₂. The effect from Ni−Co/HZSM-5 was similar but inferior to Ni−Cu/HZSM-5 in synergism; for Ni−La/HZSM-5, despite the weakest acidity and lack of synergistic effect of electrons transferring between Ni^δδδ− and La^δ−, the maximum scattering of Ni(La) species, the strongest gripper of La₂O₃ for adsorbing CO₂, and the highest ratio of A/C (6.89) synergistically generated H₂-rich pyrolytic gas with 78.29 vol % of H₂.

A large share of this negative impact arises from post-consumer textile waste recycling, owing to the vast heterogeneity of its composition. This heterogeneity originates from the waste collection process and from blended fibers in textile articles. The recycling of these textile wastes is further exacerbated by the absence of adequate sustainable solvents capable of enabling their direct dissolution and regeneration, thereby providing a practical route to textile waste recycling. It is demonstrated here that several cellulose dissolving superbase ionic liquids (SB-ILs) can solubilize natural (wool, silk, linen, viscose, cotton), synthetic (polyamide, polyurethane, polyacrylic), and blended (mohair/wool/polyacrylic, polyacrylic/viscose, polyamide/elastane) textiles, thus overcoming some of the recycling challenges. Additionally, it is shown that the textile specificity of the utilized SB-ILs can be tuned through proper selection of the anion. The utilized SB-ILs remain stable across multiple dissolution/regeneration cycles, and no apparent polymer degradation was observed. Overall, the utilization of SB-ILs presents a promising approach for the sustainable recycling of post-consumer textile articles through direct dissolution/regeneration and selective dissolution methods.</p>","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"3 8","pages":"2655–2663"},"PeriodicalIF":0.0,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148822515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a cradle-to-gate Life Cycle Assessment (LCA) of an EAF steelworks producing stainless steel, based on primary data, conducted according to ISO 14044:2006 and the Environmental Footprint 3.1 method. The analysis shows that raw material consumption represents the main environmental burden (&gt;90% of Single Score) for the five steel families analyzed (i.e., austenitic, ferritic, martensitic, duplex, and precipitation hardening), revealing substantial heterogeneity due to the steel grade final chemical composition, as high alloying generally leads to higher environmental impact. Scrap mix plays a central role in defining the alloying baseline, thus limiting the chemical gap which must be filled by ferroalloy addition. Duplex steel grades exhibit an environmental intensity (2079.66 mPt/ton) four times higher than ferritic and martensitic ones (459.57 and 447.90 mPt/ton), while precipitation hardening and austenitic grades (857.10 and 649.26 mPt/ton) represent an intermediate scenario. A critical divergence emerges between indicators: while the product carbon footprint is dominated by Cr and Ni carbon intensities, the Single Score is driven by Mo resource depletion. These findings demonstrate that steel grade heavily impacts product environmental intensity and that defossilization strategies focusing solely on Cr and Ni supply chains risk overlooking Mo.
