Lengthening Biolubricants' Lifetime by Using Porous Materials

The most of the lubricants such as automotive lubricants, gear oils, automatic transmissions fluids, engine lubricants, compressors oils... have being disposed on the environment for years, without any special care. Waste disposal is becoming a major source of concern and the tolerance of unnecessary pollution by society decreases1. As it has been described in the European General Instructions, 75/439/CEE, 78/319/CEE and 87/101/CEE, used lubricants as toxic disposals are attached to several rules and standards. One of the main problems of lubricants is the proportion of them lost into the environment in the course of routine usage2. The spillage of lubricants to the environment is one of the main problems during their routine usage. About 6 Tonnes of lubricating oils per year are lost without control which implies a hard damage to the environment
