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

Sugarcane trash (SCT) is a promising, underutilized raw material for producing value-added bio-based materials. Nanocrystalline cellulose (NCC) production conditions were obtained from the experiment. On other hand, bioethanol retrieved secondary data. This study compared environmental impact of SCT in NCC to that bioethanol. For production, was subjected organosolv pretreatment (140, 160, or 180 °C) mixed solvent system (methyl isobutyl ketone (MIBK), ethanol, and water), bleached, then hydrolyzed with different concentrations sulfuric acid (50 58%) varying times. Organosolv at °C removed 98.24 81.15% hemicellulose lignin, respectively, resulting 73.51 79.72% purity recovery. In addition, bleaching increased 95.42%. Field Emission Transmission Electron Microscopy (FE-TEM) analysis showed NCC’s small 2:1 elliptical particles found hydrolysis 50% H2SO4 45 min. The X-ray diffraction (XRD) pattern revealed 70% crystalline index values min retention Then, optimum used LCA (Sigmapro software). included global warming, marine ecotoxicity, fresh water, human carcinogenic toxicity. production’s electricity consumption (freeze-dried step) highest on analysis.
