Sugarcane bagasse, the fibrous waste left after juice extraction, is an agricultural residue particularly rich in cellulose, a biopolymer with immense potential for green materials innovation. The present work utilised sugarcane bagasse to obtain cellulose by optimising the concentrations of Sodium hydroxide (NaOH) and Sodium hypochlorite (NaOCl). Characterisation techniques such as Fourier transform infrared spectroscopy (FTIR), field-emission scanning electron microscopy (FE-SEM), and X-ray Diffraction (XRD) were employed for detailed analysis. This article also includes the effect of NaOH and NaOCl concentration on the cellulose yield and the various possible applications of the obtained cellulose. To evaluate statistical significance, a one-way ANOVA was performed, complemented by Tukey’s multiple-comparison test. Compositional analysis showed that the cellulose content of raw sugarcane bagasse was 42.6 ± 1.5%. However, after alkali and bleaching treatment, the cellulose yield ranged from 42.6 ± 0.6% to 56.5 ± 0.5%. FTIR analysis confirmed the successful cellulose extraction from sugarcane bagasse, as evidenced by the disappearance of lignin- and hemicellulose-associated peaks and the appearance of characteristic cellulose absorption bands. XRD analysis revealed an increase in the crystallinity index from 29.8% in SCB to 53.7% in extracted cellulose. Morphological analysis using FE-SEM revealed significant surface differences between SCB and extracted cellulose. Statistical analysis revealed that NaOH and NaOCl amendments significantly increased cellulose yield (p ≤ 0.05) compared with raw sugarcane bagasse. The study highlights the immense potential of agricultural waste as a renewable and cost-effective source of cellulose. By leveraging these residues, industries can reduce their dependence on conventional raw materials while promoting sustainable, environmentally responsible practices.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":487,"journal":{"name":"BioEnergy Research","volume":"19 1","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a novel magnetic biochar catalyst derived from black liquor was used. The magnetic biochar is incorporated into the HTL process to investigate its catalytic effects on the conversion efficiency of DES-treated alkaline lignin. Catalytic HTL of DES treated alkaline lignin was carried out at temperatures between 140 and 180 ℃ by varying catalysts quantity (3 to 7wt%), solvents (water and ethanol) and reaction times (60–120 min). A maximum bio-oil yield of 57% was obtained at 180 °C with 7 wt% catalyst after 120 min, as both temperature and catalyst loading were increased. Further, the magnetic biochar was characterised with X-ray diffraction (XRD), Fourier-Transform Infrared Spectroscopy (FT- IR), Energy Dispersive X-ray Spectroscopy (EDX) and Field Emission Scanning Electron Microscopy (FESEM). The final product was characterized by Gas Chromatography-Mass Spectroscopy (GC-MS) and 1 H NMR spectroscopy.

In this study, six microalgal strains and their mixed culture were selected, because they are commonly found, easy to obtain from diverse environments, adaptable for co-cultivation, and possess acceptable lipid content, to evaluate whether species diversity and complementary traits could improve biomass production, lipid accumulation, and biodiesel quality across different cultivation media. The strains and their consortium were cultivated in standard BG-11, bicarbonate-supplemented BG-11, and synthetic municipal wastewater (SMW). This study shows that the mixed culture grown in modified BG-11 have the highest lipid productivity at 35.27 mg L⁻¹ day⁻¹, compared with 33.26 mg L⁻¹ day⁻¹ in standard BG-11 and 16.16 mg L⁻¹ day⁻¹ in SMW. In contrast, nitrogen-limited SMW promoted higher lipid accumulation in some monocultures, while mixed culture improved growth stability and increased the monounsaturated fatty acid content to approximately 50–52% across media. FAME analysis further revealed that modified BG-11 and SMW promoted more favorable saturated and monounsaturated fatty acid profiles, resulting in improved biodiesel properties, with the cetane number (58.8) obtained for the mixed culture in modified BG-11.

A CFD Eulerian-Lagrangian model was developed and implemented in OpenFOAM. Model validation involved two preliminary steps: the simulation of single-particle pyrolysis to evaluate reaction kinetics and the simulation of the inert particle bed dynamics. Subsequently, three pyrolysis simulations were performed, varying the biomass injection point: the annular region, the fountain region, and the region above the fountain.

Major feedstocks such as lignocellulosic biomass, agricultural residues, food waste, industrial wastewater, sewage sludge, algae, and municipal solid waste are critically examined in relation to their availability, composition, pretreatment requirements, and hydrogen production potential. Key conversion pathways, including gasification, pyrolysis, hydrothermal gasification, biogas reforming, dark fermentation, photofermentation, biophotolysis, and microbial electrolysis, are systematically evaluated with respect to reactor design, hydrogen yield, process efficiency, scalability, and technological readiness. Particular emphasis is placed on pretreatment technologies and the trade-off between pretreatment severity and net energy balance, which strongly influence the sustainability and economic viability of lignocellulosic biohydrogen systems. In addition, recent advances in computational modeling, kinetic analysis, metabolic engineering, process simulation, and artificial intelligence are reviewed for their role in improving predictive capability, process optimization, and real-time control. The review further highlights the growing importance of hybrid systems, integrated biorefineries, engineered microbial consortia, advanced materials, and circular bioeconomy strategies in enhancing hydrogen recovery and reducing environmental impacts.
