Holistic Waste Oil & Chemicals Management

We provide the following services:


Recycling and re-refining of waste oil

Through a recycling process of physical separation by settlement, filtration or centrifugal separation, recycled clean oil can be extracted from spent oil. The recycled clean oil can then be reused in petroleum products, or be burned for energy recovery.

Re-refining is a process where waste oil feedstock is put through fractional distillation and treatment so that pure oil, free of any unwanted elements is removed. The distilled clean oil is as good as virgin oil and can be reused for a variety of applications.

At Greenchem, we use the Distillation/Clay Process which offers ease of operation in a cost effective manner. The following types of waste oil can be recycled:

  • Fuel oil

  • Diesel

  • Hydraulic oil

  • Lubricant oil

  • Cutting oil

  • Transformer and compressor oil
