Used engine, hydraulic, gear and other industrial oils are bought by re-refiners, licensed collectors and companies that process them into fuel. Because used oil is hazardous waste in most countries, both sides need the right permits.
The price depends on the type of oil, the water and solids content, contamination with solvents, coolants or other substances, and the volume. Clean, separately collected oil of one type is worth much more than a mixture; oil mixed with chemicals may have no buyer at all.
Before you offer it:
- collect different oil types separately in closed, labelled containers;
- keep water and other liquids out;
- have the waste code, and an analysis if you can, ready for buyers, and check the transport and permit rules.
On ReWasteHub, post a Sale listing in Hazardous Waste → Used Oil. Describe the type of oil, volume and frequency, storage and location. We may ask for the waste code or an analysis before publishing. Licensed buyers contact you on the platform, and documents and collection are agreed directly between your companies.
