Sugar cane bagasse (SCB), an underutilized agro-industrial byproduct from the sugar industry, is a promising feedstock for HCA extraction due to its high abundance. However, conventional alkaline hydrolysis methods for HCA extraction are hampered by prolonged processing times and oxidative product degradation. Herein, we address these limitations with a continuous anaerobic alkaline hydrolysis process employing a high-pressure screw reaction (HPSR) system. Operating under pressurized inert conditions, the HPSR system eliminates oxidative degradation while achieving rapid reaction kinetics. Instant heating and cooling allowed efficient production of HCAs (28 mg/g, ∼59% of the total extractable HCAs) in just 4 min, achieving a production rate of 8.33–11.07 mg/g biomass/min within 2 min─an order of magnitude higher than conventional batch systems. Integrating high solid-to-liquid ratio (1:10 w/v) production and downstream purification, the process achieved the scalable production of high-purity (93%) HCAs, enhancing the industrial relevance of this continuous process. To sum up, this work establishes a scalable, energy-efficient platform for valorizing lignocellulosic waste into high-value products, bridging a critical gap between laboratory-scale innovation and industrial implementation.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"1 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144587002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Development of Xanthan Gum Hydrogels Cross-Linked with Olive Mill Wastewater: A Sustainable Approach to Reusing Olive Oil Residues","authors":"Daiani Canabarro Leite, Gabriele Züge, Carolina Ferreira de Matos Jauris","doi":"10.1021/acssuschemeng.5c02141","DOIUrl":"https://doi.org/10.1021/acssuschemeng.5c02141","url":null,"abstract":"To achieve sustainable agriculture, it is essential to develop and adopt innovative technologies that take advantage of alternative raw materials and provide effective solutions for industrial waste management. This study focuses on the development of xanthan gum (XG) hydrogels cross-linked with olive oil mill effluent (OMW), a byproduct of the olive oil industry, and explores their application as an innovative strategy for water retention and soil conditioning. Biobased hydrogels are superabsorbent polymers capable of retaining large amounts of water, improving soil hydration, and reducing water stress in crops. The synthesized hydrogels were extensively evaluated through chemical characterization, swelling capacity tests, water retention performance, and thermogravimetric and morphological analyses to elucidate their structural and cross-linking properties. The results showed that the use of OMW as a cross-linking agent allowed the formation of hydrogels with exceptional water absorption capacities, ranging from 6000% to 14,000% (wt %). The analyses confirmed the successful incorporation of OMW into the polymer matrix, highlighting the interactions between the carboxyl and hydroxyl groups characteristic of the material. Furthermore, all hydrogels demonstrated the ability to retain water for up to 7 days, presented biodegradability, and did not exhibit phytotoxicity, reinforcing their suitability for agricultural applications. The OMW/XG hydrogel stands out as an economically viable and environmentally sustainable solution, offering significant potential to improve water management in agriculture. In addition to its water retention capacity, this hydrogel paves the way for the incorporation of fertilizers, creating multifunctional materials with broader applications in agriculture and horticulture. Overall, this work presents an innovative and practical approach to valorizing olive oil mill effluent as a cross-linking agent, contributing to sustainable agricultural practices and promoting the circular economy within the olive oil industry.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"10 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Exploring Heterogeneous Pd Nanocatalysts for Upgrading Acetone-Butanol Mixtures to Sustainable Aviation Fuel Precursors","authors":"Betsy Kurisingal Joseph, Pablo Doménech, Leonhard Schill, Anders Riisager","doi":"10.1021/acssuschemeng.5c02948","DOIUrl":"https://doi.org/10.1021/acssuschemeng.5c02948","url":null,"abstract":"The catalytic conversion of fermentation-derived short-chained oxygenates into longer-chained hydrocarbons offers a promising solution to obtain sustainable aviation fuel (SAF) with a low carbon footprint and maximum utilization of renewable resources. This study explores the alkylation of acetone-butanol (AB) mixtures using Pd supported on high-surface area materials with varying inherent properties, aiming to optimize selectivity toward higher ketones. To elucidate the nature of the active catalyst, all synthesized catalysts were thoroughly characterized and tested under the optimized reaction conditions for the AB alkylation. A 5 wt % Pd/MgO-HS (HS: high surface) catalyst was found to exhibit the highest selectivity (81%) for 6-undecanone, C₁₁(═O), which was attributed to an optimal balance of catalytically active sites and surface properties. Despite the absence of Pd leaching, the catalyst showed reduced activity in consecutive reaction runs. Comprehensive analysis of the spent catalyst identified the primary cause to be a transformation of the MgO support to MgKPO₄ in the presence of the K₃PO₄ base additive under the reaction conditions. The restructuring of the catalyst support led to entrapment of the accessible Pd sites, reducing their availability for catalytic reactions. The insights from the study provide a robust framework for future SAF development, particularly in the design and optimization of catalysts for higher ketone production from renewable resources.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"266 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Electrospinning Enables Embedding of PET Hydrolases in High-Melting PET Microfibers","authors":"Ann-Sophie Mizza, Yu Ji, Ulrich Schwaneberg","doi":"10.1021/acssuschemeng.5c03233","DOIUrl":"https://doi.org/10.1021/acssuschemeng.5c03233","url":null,"abstract":"Polyethylene terephthalate (PET) is produced globally at 25.5 million metric tons annually, necessitating sustainable recycling and waste treatment strategies to address increasing plastic pollution. Embedding enzymes directly within polymers by extrusion is an emerging biological degradation approach. However, the high melting temperature (<i>T</i>_m) of PET (260 °C) has previously limited this strategy since no reported PET hydrolase can tolerate such conditions. Alternatively, electrospinning is based on polymer dissolution rather than melt processing and is a promising approach to embed solvent-tolerant enzymes into polymers with high <i>T</i>_m. Here, we embedded the PET hydrolase LCC-ICCG (ICCG) in PET microfibers via electrospinning. ICCG was distributed homogeneously along the two-dimensional plane (2D plane) of electrospun microfibers and was primarily localized in surface-associated fiber layers. Over 672 h, hydrolysis of PET microfibers catalyzed by embedded ICCG yielded 85.64 mM of mono-aromatic products (10.7 ± 0.3% mass loss), despite activity reduction by exposure of the biocatalyst to the solvent solution. Electrospinning increased the amorphous content of PET from 56.15% to 72.44%, while preserving microfiber elasticity. Mechanical strength decreased by 26.29% in ICCG-loaded PET microfibers, which confirmed effective fiber degradation.","PeriodicalId":25,"journal":{"name":"ACS Sustainable Chemistry & Engineering","volume":"1 1","pages":""},"PeriodicalIF":8.4,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144586880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
