Edible oils and fats are also waste in private households. If, compared to the catering trade, the quantities are much smaller, there are also a few points to consider when disposing of them.
What is cooking oil?
- Edible oils
- Edible fat
- Deep fryer oils
In private, you can only throw away commercially available quantities, i.e. one to two liters. Commercial providers turn to professional waste disposal companies.
Old cooking oil belongs in the residual waste - not in the drain
The most important point in advance: Cooking oil, even in small quantities, should not be poured into the sink or the toilet! This clogs the pipes massively, attracts vermin and leads to problems in the sewage treatment plant.
Therefore, once the cooking oil has cooled, collect it in an easy-to-close bottle and also wrap it in newspaper or kitchen paper. Then just throw them in the trash. The wrapping ensures that the old cooking oil does not leak when pressed in the garbage truck.
What about cooking oil in glass jars? After all, throwing away glass bottles with household waste is not ideal. At the same time, however, only empty bottles may be thrown into the containers for waste glass disposal. The best solution: pour the old cooking oil into plastic bottles and then dispose of them as normal household waste.
Biodiesel from cooking oil: Vienna is leading the way
In some cases, acceptance points also accept cooking oil, or there are special collecting buckets for a collecting vehicle. The reason for this? Biodiesel can be produced from old cooking oil.
Can I add cooking and frying oil to the compost?
No, you shouldn't do that. Because the old cooking oil not only smells unpleasant and forms a greasy film, but can also cause serious damage if it gets into the groundwater. And comparatively small quantities are enough for this.
