This study presents a novel method to extract cellulose from date palm waste and convert it into hydroxyethyl cellulose (HEC). Using commercial HEC as a benchmark, the results show increased CO2 uptake up to 1.60 g CO2/g HEC and a 32.4% reduction in sodium ion concentration, demonstrating potential for brine treatment and carbon capture from agricultural waste.

日本のGX文脈において
日本ではパーム廃棄物は少ないが、CO2回収・淡水化技術はGX政策（グリーン成長戦略）に関連。廃棄物由来の機能性材料開発は循環経済の観点から注目される。
In the global GX context
This paper contributes to CCUS and brine desalination, relevant to global decarbonization efforts. The valorization of agricultural waste aligns with circular economy principles, though the specific feedstock (date palm) limits direct transferability to other regions.

📄 Abstract（原文）
Abstract. This study presents a novel method for extracting cellulose from date palm waste, a key raw material for hydroxyethyl cellulose (HEC), and demonstrates its potential in the modified Solvay process. Palm biomass, an abundant agricultural byproduct and its composition was analyzed using thermogravimetric analysis. Cellulose was successfully isolated through sequential solvent extraction, acid leaching, alkaline treatment, and bleaching, achieving a yield of 74%–76%, and subsequently converted into HEC using sodium hydroxide (NaOH) and urea solutions, highlighting its potential for valorizing agricultural waste into functional polymers. While the extracted HEC is still under optimization and detailed physicochemical characterization, the performance evaluation in this study was carried out using commercially available HEC as a benchmark material. This approach allowed for evaluating the performance of HEC in enhancing CO₂ capture and reducing brine salinity under controlled conditions using an inert particle–spouted bed reactor. The results showed that higher HEC concentrations markedly increased CO₂ uptake, reaching 1.60 g CO2/g HEC, while sodium ion concentration, the primary determinant of brine salinity, was reduced by 32.4%. These results benchmark the feasibility of using waste-derived HEC in desalination and carbon capture, highlighting its potential to convert agricultural waste into sustainable industrial materials. Future work will optimize extraction and test performance in environmental remediation.
