How We Recycle

Each year, millions of Californians change their motor oil and perform other automobile services that produce hazardous waste. World Oil Recycling provides end-to-end recycling solutions for byproducts including used motor oil, oil filters, and antifreeze, oily-waste water, gasoline waste, and more.

So what does that mean? Here’s a little more information about our recycling processes for the materials we see the most of: used oil, oily water, antifreeze/glycol, and RCRA fuels.

Recycling Oil

We are the largest used oil re-refiner in the western United States, operating 24/7 and handling millions of gallons of waste oil each year. We never stop recycling.

While some treatment facilities improperly sell or dispose of their waste oil, at World Oil, we believe in doing things right. Our Oil Recycling Unit (ORU) uses state-of-the-art processes to meet stringent requirements for recycled oil product certification, including:

  • Chemical and Physical Treatment
  • Atmospheric Dehydration
  • Fuel Stripping 
  • Vacuum Distillation
  • Lube Treatments

Recycling Water

We use state-of-the art technology to recycle oily water, bringing it down to less than 75 parts per million of oil and grease. The water-treatment process includes:

  • Oil, Water and Solids Separation
  • pH Neutralization
  • Chemical Flocculation and Demulsification
  • Dissolved Air Flotation
  • Volatile Organic Removal

We maintain the highest standard of regulatory requirements, including Los Angeles County Sanitation Department, permitting. We stand behind our facility and our end product, so you never have to worry about liability. We maintain stringent Health, Safety, and Environment (HSE) policies at all of our facilities. All employees and contractors must follow these policies and take any precautions necessary to protect both themselves and their colleagues. Safety is our top priority.

Recycling Antifreeze

Cars use antifreeze. Used antifreeze is hazardous and is prohibited by law and regulation from being dumped or discharged into sewers, drains, or septic systems. Recycling antifreeze not only protects the environment from contamination, it saves precious resources while offering customers a cost-effective, renewable alternative.

We recycle antifreeze (glycol) waste into re-refined antifreeze and ethylene glycol that meets stringent requirements, as well as ASTM antifreeze specifications. Our state-of-the-art recycling facility features:

  • Physical/Pre-Treatment
  • Chemical Treatment
  • Atmospheric Distillation
  • Vacuum Distillation
  • Carbon Adsorption

Our line of antifreeze products, marketed under the Trinity® Brand, is a top customer choice. Our clients include nationally known quick lube and tire retailers, independent shops, dealerships for non-warranty vehicles, major fleet and civic clients. Our products meet all current ASTM standards for antifreeze grade ethylene glycol, light duty, and heavy duty antifreeze products.

We have been recycling spent antifreeze and other industrial glycols for over 20 years. Our system incorporates a multi-phase recycling process utilizing pretreatment, multi-stage vacuum distillation, post polishing, and batch testing to ensure that the quality of the recycled ethylene glycol meets the ASTM E-1177 standard for antifreeze grade ethylene glycol. This base product has been tested by major antifreeze and oil companies and has also been approved for use by a major Detroit OEM in their factory fill and OES blends. Our line of Trinity® antifreeze formulations are supplied to us by major antifreeze manufacturers for both heavy duty and light duty OEMs. They have also been stringently tested, meeting ASTM D3306, D6210, and other OEM standards. In addition to normal product development testing, Trinity® products have been evaluated for chemical and performance compatibilities over a wide range of engine coolant technologies from across US, Asia, and Europe using ASTM D1384, D2809, and D4340 tests.

Recycling Fuel

When it comes to disposing of RCRA fuels, including solvents, paint-related materials, contaminated used oils, and other materials unsuitable for recycling, we take great care. Our RCRA Fuels Unit receives and safely stores waste RCRA fuels before shipping them to offsite, permitted recyclers or incinerators. It’s just one more way we’re working hard to make California cleaner today, and tomorrow.
