This study focuses on enhancing enzymatic accessibility of cellulose in oil palm empty fruit bunches by optimizing pretreatment parameters to improve glucose and ethanol yields while reducing fermentation inhibitors. It evaluates the impact of maleic acid concentrations on biorefinery processes. High maleic acid concentrations (>25% w/w) may allow reuse and offer benefits over lower concentrations, such as enhanced delignification and increased sugar yield under milder conditions. Biomass undergoes pretreatment, enzymatic saccharification, and fermentation using <i>Saccharomyces cerevisiae</i> F118. Pretreatment with 75% maleic acid (w/w) for 60 min at 180 °C effectively removes lignin and hemicellulose, increasing cellulose accessibility but results in 74.8% crystallinity, hindering saccharification. A 50% maleic acid pretreatment yielded higher glucose (77.1%). Optimal ethanol production is achieved with 1% maleic acid pretreatment. However, the ethanol yield is negatively impacted by residual maleic acid on the solid matrix.</p>","PeriodicalId":29801,"journal":{"name":"ACS Environmental Au","volume":"5 1","pages":"76-85"},"PeriodicalIF":6.7,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11741055/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143012749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanofiltration (NF)-based separations have emerged as a promising solution, offering selective separation capabilities that could advance resource extraction and recovery. However, an NF-based lithium extraction process differs significantly from conventional water treatment, necessitating a paradigm shift in membrane materials design, performance evaluation metrics, and process optimization. In this review, we first explore the state-of-the-art strategies for NF membrane modifications. Machine learning was employed to identify key parameters influencing Li<sup>+</sup> extraction efficiency, enabling the rational design of high-performance membranes. We then delve into the evolution of performance evaluation metrics, transitioning from the traditional permeance-selectivity trade-off to a more relevant focus on Li<sup>+</sup> purity and recovery balance. A system-scale analysis considering specific energy consumption, flux distribution uniformity, and system-scale Li<sup>+</sup> recovery and purity is presented. The review also examines process integration and synergistic combinations of NF with emerging technologies, such as capacitive deionization. Techno-economic and lifecycle assessments are also discussed to provide insights into the economic viability and environmental sustainability of NF-based Li<sup>+</sup> extraction. Finally, we highlight future research directions to bridge the gap between fundamental research and practical applications, aiming to accelerate the development of sustainable and cost-effective Li<sup>+</sup> extraction methods.</p>","PeriodicalId":29801,"journal":{"name":"ACS Environmental Au","volume":"5 1","pages":"12–34 12–34"},"PeriodicalIF":6.7,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsenvironau.4c00061","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143091695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
