However, the valorization of waste electronic plastics (WEP) remains challenging because the brominated flame retardant (BFR) components are easily converted to hazardous brominated organics, which lowers the product quality. Here, we report the copyrolysis of WEP with iron-rich algae biomass waste for high-quality oil production without the need for the external addition of a catalyst for bromine (Br) fixation. Iron-based flocculants are commonly used for collecting algae biomass from an algal-bloomed lake, resulting in iron-rich algae biomass. During its pyrolysis, the iron component was converted into Fe₂O₃, which served as an efficient endogenous catalyst to facilitate Br fixation and WEP depolymerization. The oil product of the copyrolysis system (WEP/AB = 1:1, 600 °C) exhibited 80% less Br content, a 30% higher fraction of total aromatic compounds, and a 15% higher oil yield than those of the WEP-alone group. Overall, our work offers a facile self-catalytic debromination strategy for WEP upcycling by simply mixing it with iron-rich algae biomass waste for copyrolysis. Such a “two-birds-one-stone” strategy may also be extended to the upcycling of other halogen-containing organic wastes.</p>","PeriodicalId":7008,"journal":{"name":"ACS ES&T engineering","volume":"5 5","pages":"1088–1098 1088–1098"},"PeriodicalIF":7.4,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921341","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}

However, existing ESPs have low filtration efficiency for submicron particles and inefficient cleaning after dust loading. Here, an ESP with a superhydrophobic coating was proposed, and the effects of the electrode gap, charging voltage, air velocity and electric field strength of the ESP on submicron particles were considered. The results revealed that the contact angle and sliding angle of the water on the coating surface were 158.0° ± 1.1° and 2.1° ± 0.5°, respectively, due to the combination of low-surface-energy groups and highly rough structures. The filtration efficiency of the submicron particles increased with increasing charging voltage and electric field strength but decreased with increasing air velocity and electrode gap. When the air velocity was 2.5 m/s, the filtration efficiency of the ESP for 0.3–0.5 μm particles reached 96.5%. The filtration efficiency remained relatively high for 28 days, with an average of 95.6%. The filtration efficiency of the ESP for 0.3–0.5 μm particles can be restored to 99.8% of the initial efficiency, while the restoration of existing ESP is 67.5%.

Electrochemical treatment processes have been widely investigated for PFAS removal. Peroxi-electrocoagulation (electrocoagulation paired with hydrogen peroxide (EC:H₂O₂)) was evaluated as a novel water treatment process for PFAS mitigation due to the multimechanistic removal pathways that can proceed during treatment, including chemical degradation via oxidation, and physical separation pathways such as sorption to flocs, flotation layer accumulation, and foam fractionation. This work investigated the impacts of varying water quality conditions and dissolved organic matter (DOM) composition on PFAS mitigation efficacy and the corresponding removal pathways. Sources of DOM were an additional point of focus to provide insight into the role of DOM characteristics (i.e., aromaticity, molecular weight) on the fate of PFAS in EC:H₂O₂. This aim was studied by conducting EC:H₂O₂ with five different types of DOM (including humic acid, fulvic acid, oxalic acid, salicylic acid, and one natural river DOM). EC:H₂O₂ was effective as a PFAS mitigation technology using a bicarbonate electrolyte matrix and different types of DOM (including reference DOM and natural DOM). Generally, PFAS removal was higher at pH 3 compared to pH 6.3, ostensibly due to enhanced oxidant yield, interactions between iron and PFAS, and foam formation. At pH 3, oxidation was a key route of removal for the carboxylic acids including perfluorooctanoic acid (PFOA) and 5:3 fluorotelomer carboxylic acid (5:3 FTCA). A combination of chemical degradation and physical separation processes contributed to the removal of sulfonic acids including 6:2 fluorotelomer sulfonic acid (6:2 FTS) and perfluorooctanesulfonic acid (PFOS). However, in the presence of DOM, especially the &lt;1 kDa low molecular weight and low aromatic autochthonous components, PFAS were more readily removed via physical sorption to the flotation layer, potentially due to the formation of DOM-iron-PFAS complexes. Regarding engineering applications, EC:H₂O₂ may have limited feasibility for PFAS mitigation in drinking water due to the highly acidic pH conditions needed and the release of metals during treatment. Accordingly, EC:H₂O₂ may better serve as a pretreatment and foam fractionation technology for higher strength wastewaters (such as membrane concentrates and industrial wastewaters) prior to more dedicated liquid-stream destructive technologies such as electrooxidation or supercritical water oxidation.</p>","PeriodicalId":7008,"journal":{"name":"ACS ES&T engineering","volume":"5 5","pages":"1202–1214 1202–1214"},"PeriodicalIF":7.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143921451","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}

A heat capacity assembly and dispatch strategy via antagonistic additive-paired sludge copyrolysis was conceived to quantitatively determine the balance for P reclamation from sewage sludge (SS). Calcium oxide (CaO, with additions ranging from 7.54 to 10%) and wasted rapeseed meal (RM, with additions ranging from 10 to 50%)-formulated copyrolysis experiments were designed to investigate the evolved fate of P and HMs in SS-derived biochar (SSB) production. Ryegrass plant cultivation was adopted to examine the orchestrated balance of P and HMs in soil applications. RM and CaO preferentially influenced the P distribution, including iron/aluminum-bound P and apatite/CaCO₃-associated P, respectively. In contrast, both additives consistently reached equilibrium with two HM ensembles, including soluble/reducible and oxidizable/residual fractions. SSB derived from RM-added (50% addition) and CaO-RM-paired (6% CaO and 47% RM addition) copyrolysis at 700 °C demonstrated preferential P acquisition of ryegrass (height increase by 17.4 and 4%, respectively) while maintaining a low HM ecological risk index (27.5 and 16.3, respectively). The kinetic and thermodynamic results confirmed that CaO and RM had antagonistic effects on the thermochemistry of sludge copyrolysis. The heat capacity reached its maximum at around 675 °C and was not affected by the paired additives.
