Material Flow Analysis of the Civil Automotive Lubricating Oil in China

As a controlled hazardous waste,wasted automotive lubricating oil has both resource recycling potential and environmental pollution risk.This research carries out the material flow analysis to find that 23% of the waste automotive lubricating oil goes to the environment through various ways.Gap exists in the recycling capacity in different provinces.In provinces with strong recycling capacity,there are a large number of enterprises with fierce competition,and the problem of illegal recycling is also prominent.In the scenario of 30% market penetration of vehicle electrification in 2030,compared with the scenario of completely traditional fuel vehicles,the amount of lubricating oil used in vehicles will be reduced by about 20%,and the eastern coastal region will take the lead in such reduction.Considering the change of automobile lubricating oil market under electrification,policies are needed to help the qualified recyclers to improve their techniques and raise the value of recycling while reduce the environmental pollution in the life-cycle of products.
