Ecological and technical aspects of the waste oils influence on environment

Abstract

In the last ten years, the world demand for lubricants is around 36 millions tons per year. More than 50 % of that amount is lost in exploitation, and the rest is potentially collectable waste oil. Waste oils are a serious threat to the human health and especially the environment. In order to prevent this threat, a proper waste oil management should be adopted. The solutions for the environmental protection comprise the following activities: the reduction of quantities of waste lubricating oil, the organized collection of the waste lubricating oil and recycling of waste lubricating oil.
