Waste management of engine oil waste

Engine oil waste is a highly polluting material that requires responsible management. This study aims to investigate the used engine oil waste management system, the effects of engine oil emission and leakage in soil and aquatic environments, and the environmental impact of excess fuel combustion. The present study is a review research and the literature has been used for data collection. Research results show that the said system includes components for collection, reuse, recycling, transportation, incineration, and disposal. After consuming some of the used oils, these oils are collected and refined and are returned to the consumer as new oil. In many purification processes, recovery and disposal of acid sludge is the main problem of in its transfer. Recycling such contaminants will be useful in reducing engine oil losses, in addition to having a significant positive effect on the environment. Reuse as fuel requires only physical refining, while recycling requires refining used oil with comprehensive processes. Excess engine oil can cause damage to the environment when it is discharged on the ground or into streams, including sewage, which also contaminates groundwater and soil. The production of alternative fuels from oil waste reduces the consumption of oil-based fuels. Using waste engine oil to produce diesel fuel seems to be a suitable method to produce alternative fuels.
