However, their practical application in oil spill remediation is often limited by insufficient mechanical resistance, poor hydrophobicity, and challenges in cost-effective processing. To address these limitations, this study proposes a novel approach aligned with Green Chemistry principles, developing an oil sorbent entirely from sugarcane bagasse (SCB) through a sustainable two-step process. First, the biomass was deconstructed via physical milling and hydrothermal treatment with water at 200 °C. Then, the fiber network was reconstructed by incorporating 0.1 wt % cellulose nanofibrils (CNFs) derived from SCB, followed by oven-drying. This is the first report to explore the synergistic effect of redeposited lignin nanoparticles (LNPs) and CNF reinforcement to produce a robust and hydrophobic sorbent from SCB. The resulting sorbent exhibited enhanced mechanical resistance, supporting loads greater than its own weight without structural failure. It also showed inherent hydrophobicity and high oleophilicity with absorption capacities of 4.1 g/g for corn oil, 3.5 g/g for light crude oil, and 5.1 g/g for medium crude oil. Microscopy analyses confirmed the presence of LNPs on the fiber surfaces after hydrothermal treatment, contributing to hydrophobicity alongside micro- and nanoscale surface roughness from fiber packing and LNPs. This work demonstrates how hydrothermal treatment combined with CNF reinforcement can effectively convert sugarcane bagasse into a high-performance, cost-effective, and eco-friendly sorbent for oil spill remediation.</p><p >This Article presents an eco-friendly sorbent material developed from sugarcane bagasse, focusing on sustainability and oil spill remediation.</p>","PeriodicalId":100015,"journal":{"name":"ACS Sustainable Resource Management","volume":"2 5","pages":"853–863 853–863"},"PeriodicalIF":0.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acssusresmgt.5c00110","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144104925","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}

Herein, we report on the use of palm biomass as a precursor of activated carbon (AC) to recover gold from e-waste. The current study utilizes random forest algorithms for the optimization of AC’s production from four types of palm biomass. Based on the optimization result, the highest conversion was achieved by palm fiber biomass, with &gt;80% conversion at 600 °C. AC showed a moderate adsorption capacity toward Au at 64 mg/g. Optimization of the adsorption process was carried out by response surface methodology, resulting in an acceptable error value that indicates the suitability of the model. Under optimal conditions, 89.9% adsorption efficiency was achieved with an adsorbent dosage of 10 g/mL, an activation temperature of 600 °C, a Au concentration of 152 mg/L, and an adsorption temperature of 30 °C. The mechanistic modelling of the process shows a suitable fit with the pseudo-first-order kinetic model and the Langmuir isotherm model. Furthermore, the thermodynamic analysis indicated that gold adsorption was an exothermic and spontaneous process.
