摘要

Banana pseudostem has been widely investigated as a non-wood fibre source; however, the combined technical and environmental performance of ambient-temperature alkaline pulping has not yet been systematically evaluated. This study developed a decentralizable, ambient-temperature alkaline pulping route to produce wrapping paper originating from banana pseudostem in Vietnam. The best operating state of NaOH 3% for 12 h was selected using a combined criterion of tensile strength and environmental efficiency index (EEI), capturing the point at which further increases in alkali severity yielded smaller mechanical improvements while incurring greater environmental burden. The used alkaline liquor could be reused with minor replenishment, showing that multi-use operation can markedly reduce NaOH-related Global Warming Potential (GWP) while at the same time maintaining acceptable paper performance. Additive 0.5% cationic modified starch (CMS) was identified as the most effective strengthening dosage. It was also found that adding 4% glycerol improved the flexibility of paper sheets without compromising their key properties. A process-level environmental assessment (ecoinvent v3.12) indicated a favorable impact profile for the ambient route, with GWP = 26.11% relative to the benchmark scenario. This supports the benefit of eliminating thermal cooking and the suitability of decentralized implementation in Vietnam under conditions of dispersed biomass supply and high pseudostem moisture content.
