In the quest for sustainable solutions to replace mineral-based lubricants, researchers have turned to an unlikely duo: palm oil and Aloe vera. A recent study published in the journal *Tribology and Materials* (which translates to “Friction and Materials”) has revealed promising results in the development of biolubricants that could revolutionize the energy sector.
Riky Stepanus Situmorang, a researcher from Universitas Sumatera Utara in Medan, Indonesia, led the investigation into the synthesis and characterization of biolubricants formulated from palm oil methyl ester (POME) and Aloe vera (AVE). The study evaluated various formulations with different POME:AVE volume ratios to determine their suitability as cutting fluids in metalworking applications.
The findings are significant. The 60:40 POME:AVE ratio demonstrated the best overall performance, with the highest viscosity, lowest pour point, and notable thermal stability. These improved properties are attributed to the bioactive compounds in Aloe vera, such as acemannan, polysaccharides, and natural antioxidants, which enhance molecular cohesion, thermal resistance, and oxidative stability.
“These compounds contribute to the enhanced performance of the biolubricant,” Situmorang explained. “They improve the lubricant’s ability to withstand high temperatures and resist oxidation, making it a more reliable and durable option for industrial applications.”
The study also found that the 60:40 biolubricant formulation significantly reduced cutting temperatures during CNC lathe machining compared to commercial and dry machining conditions. This is a crucial factor in metalworking, where high temperatures can lead to tool wear and reduced efficiency.
The implications for the energy sector are substantial. As industries increasingly prioritize sustainability, the development of eco-friendly lubricants that do not compromise on performance is a game-changer. Biolubricants formulated from POME and AVE could offer a sustainable and high-performance alternative, reducing the environmental impact of metalworking processes.
“This research opens up new possibilities for the use of biolubricants in various industrial applications,” Situmorang noted. “It’s not just about being environmentally friendly; it’s about delivering performance that meets or exceeds traditional lubricants.”
The study’s findings suggest that biolubricants formulated from POME and AVE have strong potential as sustainable and high-performance alternatives in metalworking applications. As the energy sector continues to evolve, the adoption of such innovative solutions could play a pivotal role in shaping a more sustainable future.
The research, published in *Tribology and Materials*, highlights the importance of ongoing innovation in the field of biolubricants. As industries strive to reduce their environmental footprint, the development of effective and sustainable lubricants will be crucial. This study not only advances our understanding of biolubricants but also paves the way for future developments in the field.
