Lubricating Grease Handling and Waste Management

Abstract

Lubricating grease just like any other lubricants, its waste require careful disposal as it contain pollutants. In response to economic considerations and environmental protection, there is a growing trend of regeneration and reuse of waste lubricants. Accordingly, this work provides an overview on various ways of handling, disposal, treatment of waste grease and its associated environmental impacts. In addition to the fact that petroleum and crude oil are not inexhaustible resources, waste products from these resources present a hazard to human health and the environment. Thus proper management of waste grease is necessary to prevent the adverse environmental impacts, in this regard efficient recycling of waste lubricating greases could help reduce environmental pollution. A review is also made to get an insight into existing literature and what ideas are available for future development through general recommendations regarding the use of renewable resource-based ingredients as a replacement for traditional synthetic materials in conventional greases.
