The process demonstrated that the conversion of those feedstocks and hydrocarbon product selectivity varied according to the catalyst and feedstock properties. The Zn/SBZ catalyst possessing the ideal combination of micro-mesopores and acid sites exhibited 100% conversion for those feedstocks to produce liquid products composed of mainly 72-75% aromatics and 25-28% larger non-aromatics (C₈–C₁₅ naphthenes and C₇–C₁₂ iso-paraffins) with the research octane number (RON) of 100 suitable for sustainable aviation fuel applications. The Zn/Z catalyst only with micropores and predominant acid sites appears to be a suitable catalyst for gasoline production due to its high aromatic selectivity (83-85%) and favorable RON (105), although it showed relatively low conversion (∼80%). It was also discovered that the SBB’s high hydrocarbon constituents made it a better feedstock for the production of hydrocarbon fuel than the PBB.

Antimony trioxide is initially incorporated into these plastics in synergy with brominated molecules, hence their common name “brominated plastics”. This combination offers excellent flame-retardant properties. The mechanical recycling of brominated plastics is prohibited due to the hazardous nature of the molecules that are generated during the process. Therefore, this Review explores the use of a plastic dissolution method combined with liquid–liquid interfacial leaching to remove antimony trioxide while recovering a plastic cleansed of this problematic additive. The primary investigative focus pertained to the refinement of the aqueous extractant solution, while the secondary focus centered on the selection of the dissolution solvent. The process demonstrates high efficiency in antimony extraction, achieving up to 98 mass % recovery, with minimal impact on the structural integrity of the acrylonitrile–butadiene–styrene plastic. By insolubilization of the plastic to recover it, it is also feasible to recover up to 98 mass % of the brominated molecules, thereby ensuring compliance with legal thresholds for the reuse of plastics.

TiO₂ was synthesized using the peroxide gel method to be supported on these ACs, which were extensively characterized. The ACs exhibited high specific surface areas (up to 1600 m² g^–1) and pore volumes that were suitable for supporting TiO₂. TiO₂ maintained its anatase phase after synthesis and dispersion on the ACs, with 10 ± 2 nm crystallite sizes. SEM and TEM analyses revealed good dispersion of TiO₂ nanoparticles on the AC surface. Photocatalytic assays showed that the AC-TiO₂ composites efficiently degraded N-acetyl-para-aminophenol (APAP) under ultraviolet (UV) light, surpassing pure TiO₂. Composites with higher TiO₂ content (85%) exhibited the best performance on the photodegradation, degrading 74% to 82% of APAP over 5 h. Pseudo-first-order kinetics indicated enhanced degradation rates for the composites compared to TiO₂. Furthermore, the AC-TiO₂ materials showed sustained photocatalytic activity over multiple cycles, confirming their stability and practical potential. XRD analysis verified the stability of the composites after six reuse cycles.

Natural cellulose is a recalcitrant material because it is insoluble in common solvents and exists in a rigid crystalline form. Accordingly, the direct hydrolysis of crystalline cellulose to its monomer, namely, glucose, is a grand challenge in biorefining. In this work, we propose an idea of using nano-sized catalysts to overcome this issue. Specifically, a small and highly mobile carbon-based catalyst can attach to rigid crystalline cellulose so that it can hydrolyze the attached cellulose. The catalyst was synthesized simply by oxidizing cellulose with air and nitric acid. The nanostructure of the catalyst was revealed by several physicochemical techniques. The nano-sized catalyst hydrolyzed crystalline cellulose to glucose in up to 58% yield by repeating the reaction. Moreover, the catalyst works even at a high cellulose concentration of 16 wt % and at a high substrate/catalyst ratio (32 w/w), giving a 6 wt % glucose solution in a one-pass reaction. The catalytic performance is far higher than that of conventional micron-sized catalysts. Adsorption of the catalyst on crystalline cellulose was confirmed by adsorption experiments and quantum calculations. These results demonstrate that designing nano-sized catalysts is a hopeful strategy to overcome this essential issue in biorefining.</p>","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 3","pages":"546–553 546–553"},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703741","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}

Current practices reveal that a minimal fraction of plastics achieves true circularity, with materials being continuously reused with no compromise in their quality, because the majority of plastics are subject to a linear lifecycle, often culminating in landfills or incineration, actions that negate the principles of circular economy. Innovations in polymer chemistry and recycling technologies are pivotal for enhancing the circularity of plastics and biobased plastics but present a partial solution and face challenges related to production scalability and lifecycle impacts. In the present paper, we aim to clarify any misconceptions related to the “linear vs circular” use of plastics, underpinning the strides being made toward making plastics more circular, while dealing with substantial gaps remaining to achieve a true circular economy. A multifaceted approach involving technological innovation, regulatory frameworks, and behavioral change is necessary to improve the circularity and sustainable treatment of today’s plastics. Policy and consumer behavior play critical roles, while mandating recycled content and enhancing waste management infrastructure are essential. Finally, consumer awareness and participation in recycling programs can drive demand for recycled materials and reduce contamination in recycling streams.</p>","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 3","pages":"375–385 375–385"},"PeriodicalIF":0.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703729","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}

In this study, crude protease enzyme was used to extract keratin from sheep hair waste in an eco-friendly manner. The bacterial strain for enzyme preparation was isolated from the soil of a waste dumping site. A mild NaOH (0.2 M) solution was used to break down the disulfide bond of protein which followed the enzymatic hydrolysis process to extract keratin. Several reaction parameters (time, temperature, and pH) of the extraction process were optimized using response surface methodology (RSM). The extensive analysis of data by RSM revealed a hydrolysis time of 5.54 h, a temperature of 54.90 °C, and a pH of 7.87 to be optimum for achieving a maximum keratin yield of 45.43%. Under optimal conditions, laboratory tests produced a keratin yield of 44.77% with a 1.48% error. This approach significantly reduces chemical use and process duration while maintaining higher yields compared to conventional methods. Protein content analysis using the Bradford method and Kjeldahl method showed that the method recovers 84.49% and 94.82% of the protein from the hair waste, respectively. Cost analysis demonstrated that only $19 is needed to obtain 100 g of keratin from tannery hair waste, confirming its economic feasibility.
