Frying fat, cooking oil and oily gravy can be recycled if you return them separately.

You can offer leftover frying fat and cooking oil to the managers of one of the environmental centres Or at the Kringlooplein New Lekkerland. Some supermarkets, DIY stores, thrift shops and (sports) clubs also have a special collection bin for frying fat and cooking oil.

Tips for returning frying fat and cooking oil

  • Let the frying fat, cooking oil or oily gravy cool first.
  • Pour it back into the original container or another sealable container, such as a milk carton or plastic bottle with a screw cap.
  • Close the packaging tightly.
  • Deliver the frying fat with packaging and all to one of the environmental centres.


  • You should not put deep-frying fat in a frying pan you want to dispose of. The reason is that the grease runs out of the pan during transport. And it contaminates the other discarded electrical equipment in the container; this is unhygienic and unsafe (slip hazard) for the recycling worker. It also complicates the recycling of the equipment.
  • Do not flush oil and fats down the sink, they will clog your drains and sewers.
  • Lubricating oil and grease are small chemical waste (kca). Deliver it to the environmental street.


Frying fat and cooking oil are recycled. They are raw materials for producing biofuel or biodiesel. Biofuels cause fewer emissions of CO2 and particulate matter than fuels made from mineral oils. The fat and oil are given a second life, they are not incinerated with residual waste. This is good for the environment. Help out and deliver fats and oil separately.
