Conversion of Sugarcane Trash to Nanocrystalline Cellulose and its Life Cycle Assessment

“…Then, 84 mL of deionized water was added to the solution immediately, followed by autoclaving at 121 • C for 1 h. Cellulose and hemicellulose were determined from the liquid fraction, which had been neutralized using CaCO 3 that was analyzed using HPLC (Shimadzu, Kyoto, Japan) equipped with an Aminex HPX-87H (Biorad, Hercules, CA, USA) column and a refractive index detector (RID). Lignin was determined from the solid heating fraction at 105 • C for 4 h, then burnt at 575 • C for 2 h [65].…”

Optimisation of Bioethanol Production in a Potato Processing Industry

“…The raw materials and residues were characterised according to the NREL laboratory analytical protocol [20,21]. After every technical process, all the samples were centrifuged for 9 min at 3100 rpm, in order to proceed for further chemical analysis.…”

“…After every technical process, all the samples were centrifuged for 9 min at 3100 rpm, in order to proceed for further chemical analysis. In the solid fractions, the total solids, volatile solids, moisture, ash, lignin (acid-soluble lignin and acidinsoluble residue), hemicellulose, cellulose [20] and starch [21] were measured. The starch was estimated by the Total Starch Assay Kit, using the AOAC Method 996.11 (K-TSTA-100A, Megazyme, Wicklow, Ireland) [22].…”
