Abstract

n the European countries around 600 000 t of lubricants are released into the environment through normal use such as chain saw oils railway points greases and two-stroke engine oils every year. The toxicity and biodegradability of lubricants are a crucial aspect in managing the sustainability of environmental. This article is intended to evaluate the biodegradability of palm-based lubricants in order to establish their environmental-friendliness. The respirometric method was used to monitor the biodegradation of lubricant samples over 28 days as described in the OECD 301F Test Method. The results showed that palm-based lubricants; mould oil BO-20 and BO-18 readily biodegraded in aquatic environment with the biodegradability of mould oil reached 62.7 within 23 days BO-20 reached 62.8 within 11 days and BO-18 reached 63 within 14 days which surpassed the 60 pass level within the test period. Meanwhile the petroleum-based lubricants mineral oil and motor oil were not readily biodegraded when tested according to standard method OECD 301F as their biodegradability did not surpass the 60 pass level within the 28 days test period. The viscosity of a lubricant may also be used as an indicator in predicting the biodegradability of that lubricant. The petroleum-based white oil for example has a low viscosity and it is readily biodegradable. The petroleum-based lubricant which is not readily biodegradable may cause problems when it comes to loss lubricants accidental spillage and disposal. The use of palmbased lubricants are more environmental-friendly and are one of the alternatives to reduce adverse effects of lubricants on ecosystem.
