A comparison of waste lubricating oil treatment techniques

Waste lubricating oil is a resource that cannot be disposed of randomly due to the presence of pollutants. In response to economic problems and environmental protection, there is a growing trend to regenerate and reuse waste lubricants [1]. The recovery techniques discussed in this paper are reprocessing, rerefining and incineration of waste lubricating oil. The major objective of this paper is to analyze and compare the regenerative technologies, thus creating the foundation for government, the private sector and other stakeholders in policy formation and selection of recovery techniques
