What actually happens to the oil after a periodic oil change on a car? To put it briefly: the garage must dispose of the waste oil properly. This procedure is also equally time-consuming and costly in an industrial operation and requires appropriate specialist knowledge. Users of the unique quasi-dry machining developed by UNILUBE can sit back relaxed on the contrary, as the issue of disposal does not normally arise for them in the case of residue free lubrication. Only in rare cases where there are outdated leftovers in the warehouse would these have to be disposed of too. For this case, we are pleased to give you the following information.
When it comes to waste disposal, the UNILUBE high-performance lubricants fall into the category of “synthetic machining oils”. If we leave out marketing designations, the term “synthetic” relates solely to the chemical method or process with the aim of producing oils.
Synthetic products like those from UNILUBE, which are of plant and animal origin, are classified completely differently to synthetic engine oils with regard to their disposal. If sorted unmixed, UNILUBE lubricants can be recycled in a biogas plant.
We should point out that, for any disposal, the regional and national provisions must always be observed and complied with and that these may differ from our opinion.
Oil collection points differentiate, if at all, between two waste oil categories: on the one hand, cooking oil, and on the other, engine oil. In Switzerland, for safety reasons both are rated as hazardous waste as soon as they are handed in at a public collection point.
The distinction is really only applied in the B2B sector, where cooking oils respectively oils of animal or plant origin are used again as biodiesel or are literally vaporised in biogas plants.
In contrast, waste oil such as engine oil or mineral-oil based and synthetically produced oil must be incinerated in a hazardous waste incineration plant. The technically elaborate hazardous waste incineration plants are often found in the cement industry, where the combustion energy can still be put to good use. The filters from the hazardous waste incineration plants ultimately end up in a hazardous waste landfill.
The treatment of waste oil only makes sense when it is available unmixed in large quantities and can then be used as a raw material for a lower quality oil. This is seldom the case, however.
The disposal of oil is a large cost factor and should therefore be taken into consideration even at the evaluation stage of a minimal lubrication system. It is precisely here that the major advantages of the UNILUBE residue free lubrication become apparent, as disposal is not an issue at all. The smallest quantities of high-performance lubricant are immediately used up in the metal cutting process.
