Frying fat & cooking oil

Bin: Yellow drum with screw cap

Becomes biofuel — never down the drain.

Used frying fat and cooking oil are a valuable feedstock for biofuel. Down the drain they cause fatbergs and blockages; in residual waste they are simply lost.

This belongs in it

  • Used frying fat, liquid or solid
  • Cooking oil and salad oil
  • Fat and oil from the pan — cooled down
  • Leftover oil from jars and tins

This does not belong in it

  • Engine and machine oil (hazardous waste)
  • Water with fat from the grease trap
  • Packaging — that goes in PMD
  • Food scraps in the drum

What happens to it?

  1. 1. Cooled into the drum

    Let the fat cool and pour it into the yellow collection drum with a screw cap.

  2. 2. Collection

    The full drum is collected and swapped for an empty one.

  3. 3. Cleaning

    At the processor the fat is heated, stripped of water and food residue, and filtered.

  4. 4. Biofuel

    The purified fat is converted into biodiesel or renewable diesel.

Where is it processed?

Processed by an approved collector and refinery of used vegetable oils and fats.

This is what it becomes

  • Biodiesel and renewable diesel (HVO)
  • Feedstock for the chemical industry

Rules and legislation

Frying fat does not belong in the sewer or in residual waste. It is collected by an approved collector and processed into biofuel; collection is usually free of charge because the fat has value.
