Abstract
This paper reviews the handling, disposal, treatment
of waste lubricating grease as well as its environmental impact.
Lubricants require careful disposal as they 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. As such, proper management of waste
lubricants is necessary to prevent the adverse environmental
impacts. Efficient recycling of waste lubricants could help reduce
environmental pollution.
