Marki-Arvela et al. reviewed the conditions reported for the extraction and hydrolysis of cellulose. Due to its resilience, most available methods suffer from drawbacks such as corrosion and waste management issues for strong acids or the need of high temperatures for mild acids, both leading to significant dehydration of sugars, whereas the use of mineral acids generates large amounts of salts after the neutralisation steps. Physical (ball milling, grinding, steaming) or chemical treatments (SFE) can be applied to soften the crystalline structure (rated as CrI for Crystallinity Index) to amorphous cellulose, showing how resilient this fraction is, compared with hemicellulose. An alternative method to produce glucose from cellulose are the vapours of HCl at 0°C. One of the most efficient way to valorise cellulose is through enzymatic hydrolysis, in comparison with hemicellulose that can be more easily degraded with simpler conditions and where a microorganisms inhibitors are still present which lowers the efficiency of such enzymes. With a similar approach than Lynch et al. The main applications reported in the literature for BSG's cellulose are its use for ethanol production or as substrate for enzymes, yeast or fungi growth. However, higher value applications, such as CNC are preferred for cellulose and most of the time for these applications, only the cellulose containing fraction is utilised, whereas a complete use of the fully fractionated LCB would be preferred, economically and environmentally.
