What we do

Re-refining waste oil is an industrial process involving the collection of used lubricating oils, their treatment to eliminate contaminants, and the re-refining to produce base oils.

The results are base oils categories used for the lubricants markets. These re-refined base oils are versatile and can be used in various applications such as automotive lubricants, industrial oils, and other lubricating products.

The re-refining industry plays a vital role in recycling and repurposing waste oil, contributing significantly to sustainability and resource management while meeting the lubrication needs of diverse sectors.

Re-Refining Process

Used Lubricants

Oils that have been previously used in engines, machinery, or industrial processes, become contaminated and less effective over time. Used Lubricants are also referred to as waste oil.


Waste oil is collected and evaluated by authorized companies or facilities to determine its suitability for re-refining. This step involves proper storage and transportation of waste oil to prevent environmental harm.


Waste oil is treated through chemical processes to remove contaminants, dirt, and solid particles, and to eliminate water and lighter oils via vacuum distillation. This can either be followed by hydrotreating under high pressure and temperature in the presence of hydrogen to remove sulfur or solvent extraction may be applied to further refine the base oil, addressing specific contaminants and achieving the desired oil quality.


The refined base oil is mixed with various additives to create new lubricants with specific performance characteristics. Quality control is crucial in this step to ensure the final product meets performance criteria.

Returning to the Market

Blended lubricants which are refined through the re-refining process and verified through quality control, are distributed to the market for use in engines, machinery, and industrial processes. With their approvals, they meet the same requirements as lubricants made from virgin base oil.
