Used oils
Used oils are only slightly biodegradable; their disposal in the natural environment is therefore hazardous for natural systems .used oils thrown into any waterbody will reduce the amount of oxygen available for the flora and fauna.
Important!
- 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.
Used oils must be handed over to one of the following professionals:
- approved recycler,
- approved waste recycling centre,
- approved final disposal agent
Used oils are divided into two categories:
- So-called clear oils, of industrial origin and little deteriorated in use, which can easily be regenerated through a simple purification process (filtering and/or centrifugation).
- So-called dark oils, mainly originating from automotive lubrication, which have been subject to severe thermal and mechanical conditions, under which they have been loaded with metals and combustion residues and oxidized. Neither of these oils should be confused with used soluble oils and other aqueous machining fluids, or vegetable frying oils, or water-hydrocarbon mixtures for which entirely different methods for collection and disposal are used.
