Life cycle assessment of synthetic polyolester oil-based biolubricant filled with bacterial cellulose nanofiber
The challenge to increase lubrication consumption made of natural resources to support sustainable development has been eagerly researched lately. Lubricants with the addition of cellulose as additives can be a substitute for conventional lubricants. This study aims to identify significant impacts and determine alternative improvement scenarios with minimum potential implications for the experimental research of biolubricant products' life cycle. In this work, Life Cycle Assessment (LCA) cradle-to-gate method was carried out. The most significant potential environmental impact acquired was global warming (GWP), which reached a value of 14.600 kgCO2eq. This value was generated mainly through synthetic oil used as the biolubricants base fluid in this work. The implementation scenario showed that palm oil fatty acid methyl ester (FAME) could reduce the GWP and Human Toxicity impact by ~21% and 51%, respectively, compared to synthetic oil.
