Saheli’s awareness of environmental issues has led us to develop a range of eco-friendly products for use in many applications where leakage or accidental spill can occur and cause serious damage to the environment.
Furthermore, Saheli provides you with advice beyond practical rules about handling lubricants and greases, as well as managing waste products to reduce environmental impacts.
There are two main types of waste oils:
- Black oils, regrouping motor oil and some industrial oils (tempering oil, metal rolling oil, wire drawing oil, etc.). These oils after use are highly degraded and contaminated, having undergone severe mechanical and thermal stresses and then heavily loaded with metals and residues from combustion. They mainly come from automotive lubrication.
- Light oils, mainly from industrial applications, transformers, hydraulic systems, turbines, etc. These oils are generally slightly contaminated or deteriorated. They can easily be regenerated by simple purification (filtration, centrifugation).
Generally, waste oils are not biodegradable. They have a lower density than water. Therefore, 1 litre of used oil can cover an area of 1,000m2 of water and reduce oxygenation of the fauna and flora. The consequences of a direct discharge of waste oils into the nature are obvious.
Furthermore, although the calorific value can be estimated at about 90% of heavy fuel, the impact associated with its combustion under not appropriate conditions may also be important: carcinogenic hydrocarbons, hydrogen chloride, dioxins, etc. may be released.
Used oils may still be recycled or ”re-evaluated” by Regeneration or Evapo-incineration or Incineration:
- Regeneration consists in obtaining fresh new base oil by vacuum distillation with a clay finishing. This method is mainly used to recycle light oils.
- Incineration is an energy recovery in the form of electricity or heat recovery, or as fuel for certain industrial applications. Example: Can be used as a substitute for heavy fuel oil in cement kilns. This method is used primarily for black oils.
- Evapo-incineration consists in evaporating the water and then incinerate waste oils as with resultant energy recovery in the form of electricity or heat. This method is used for soluble oils.
How to handle the used oils ?
Used oils must be stored in airtight packaging in shelters and on an impermeable floor dike-shape floor to mitigate the risk of leakage or spillage.
Avoid mixing up with water or non oil-based products.
Do not throw away your used oils in the soil or in the gutters or drains.
In our environmental policies, we are setting up a collection network to help you get rid of your disposable waste oils.
Upon your request, our staff will provide you secured containers, especially designed for the storage and the collection of waste oils.
Bad habits are now over! We must therefore commit to work together to protect our soils, our water, our atmosphere and the whole environment.
What not to do?
- Never throw used oils in waste traps, waste fills, gutters or drains
- Never use them as a weed-killer
- Never use them for protecting woodwork
- Never use them as heating fuels
