Used oils, greases and emulsions

fire polution silhouette
Mineral oils: (natural and synthetic): Hydraulic oil, lubricants; engine oil, gear oil
emulsions: oils with water, oil radiators, liquids containing PCB, thermal oils, contaminated fuels, fuel, diesel, mazout
Separator contents; mud from used water treatment


Industrial oils and greases, fuels and emulsions contaminate water and soil and are inflammable. When used oil drops to the ground water, the water will become undrinkable. Due to the combustibility a safe storage is important. Mineral oils contaminated by solvents or other organic fluids may not be treated. The highly toxic PCB (poly-chlorated biphenyl) was used in the seventies as additive in electric oil radiators, condensers and transformers and may still exist in older devices.


Waste prevention through clean work and adequate application techniques.

Use recycling oils with long lifetimes and machines and appliances with low oil consumption.

Recycling/environment correct disposal:

Uncontaminated mineral oils are recycled. Emulsions are separated and the oil used as energy carrier. Contaminated oil and oils containing PCB undergo high temperature treatment. Contaminated fuels undergo thermal treatment.

Separator contents undergo chemical / physical treatment in special installations to allow for thermal recycling of the oil.
