TI  - Comparative Study of Green and Traditional Routes for Cellulose Extraction from a 
      Sugarcane By-Product.

AB  - Sugarcane bagasse (SCB) is the main residue of the sugarcane industry and a 
      promising renewable and sustainable lignocellulosic material. The cellulose 
      component of SCB, present at 40-50%, can be used to produce value-added products 
      for various applications. Herein, we present a comprehensive and comparative 
      study of green and traditional approaches for cellulose extraction from the 
      by-product SCB. Green methods of extraction (deep eutectic solvents, organosolv, 
      and hydrothermal processing) were compared to traditional methods (acid and 
      alkaline hydrolyses). The impact of the treatments was evaluated by considering 
      the extract yield, chemical profile, and structural properties. In addition, an 
      evaluation of the sustainability aspects of the most promising cellulose 
      extraction methods was performed. Among the proposed methods, autohydrolysis was 
      the most promising approach in cellulose extraction, yielding 63.5% of a solid 
      fraction with ca. 70% cellulose. The solid fraction showed a crystallinity index 
      of 60.4% and typical cellulose functional groups. This approach was demonstrated 
      to be environmentally friendly, as indicated by the green metrics assessed 
      (E(nvironmental)-factor = 0.30 and Process Mass Intensity (PMI) = 20.5). 
      Autohydrolysis was shown to be the most cost-effective and sustainable approach 
      for the extraction of a cellulose-rich extract from SCB, which is extremely 
      relevant for aiming the valorization of the most abundant by-product of the 
      sugarcane industry.
