Researchers from School of Chemistry devise process to regenerate and reuse waste engine oil

Shoolini University's School of Chemistry has come up with a novel experiment of regenerating lubricating and engine oil waste. Now patented, the experiment has potential to make waste oil reusable which otherwise would have been disposed, thus adding to the waste. Their project has been titled ‘Regeneration of waste engine oil using Bio-waste derived nano-materials’. 


The researchers, Dr Amit Kumar, Dr Gaurav Sharma, Sunil Sharma, Anu, Ajay Kumar and Sangeeta are key players in making this project successful. During their experiment, they realized that waste can be used to treat waste oil. To execute their idea, they first needed to create a material out of waste that can be used to treat waste oil. Thus, they first collected distillery wastes (Barley) from a local brewery industry. Next, they produced a highly porous magnetic biochar material by controlled (gradient) sintering and use of iron and cobalt salts. 

The researchers followed the process to treat engine oil collected from garbage. This process has a number of stages. One was sedimentation, whereby waste oil was first allowed to sediment. Thereafter, the oil underwent acid treatment after being distilled. Subsequently, the processed oil passed through alkali treatment. Finally, leaching was applied to the oil by magnetic biochar. Clear oil was obtained through the entire process only after 3 days of experiment. 

Researchers evaluated the quality of oil using the parameter of the final oil. They found that the oil generated was good and fresh. This oil can be reused for many cycles and is recoverable.

Increased use of motor vehicles is elevating the waste engine oil, which is often disposed improperly. This has made waste lubricating and engine oil a serious threat to the environment. This project is an effort to ward off such threats.
