Production of Lubricant Oil from Anacardium occidentale Extract

autorzy: ARIAN CAMADDU

In 2010, Philippines is sixth among the top ten (10) producers of Cashew nutshell in Asia. However, due to its high demand of production, about 0.75 metric tons (MT) of wastes were produced locally that thought to be unfeasible. Cashew Nutshells are greatly known to produce significant amount of lubricant oil due to the presence of Anacardic acid and small amount of phenolic compounds. Thermal Extraction process through an open pan roasting was used in producing Cashew Nut shell Liquid (CNSL) as lubricant oil for defective and corroded screws, pliers, and bearings. This method is commonly used by small scale industries where the produced oil was a valuable source of natural phenol. 50 mL of lubricant oil was then produced from 80 g of waste cashew nut shells through roasting method. A dark reddish brown liquid was collected which gave noteworthy effects on different materials (screws, pliers, and bearings) in terms of greasing characteristics (types of service, texture, oxidation resistance, consistency) as compared to commercial and imported lubricant oils such as WD-40 and Singer Lubricant. One to two minutes effectivity rate was then recorded when CNSL was placed on corroded bearings and pliers. Mechanical testing was used to evaluate the efficacy of the lubricants where its greasy effect lasted for several days making the materials more useable and less rusty. CNSL opens new progress on producing low-cost lubricants that can be available for small-scale industries due to its affordability and effectivity where sustainability and reduction of wastes are its main goal. Key Terms: CNS Lubricant oil, grease, roasting method
