What?
This is a paper or card
Where?
If this is from a frozen, home-cooked pizza the packaging should be clean and should be placed in the household recycling bin.
If you had a take away pizza, parts of the cardboard will likely be contaminated with grease. Greasy cardboard should be placed in the brown bin and clean cardboard should be placed in the recycling bin.
How?
Separate greasy cardboard from the clean parts by cutting or tearing them out before placing in separate bins.
Please make sure items are clean, dry and placed loosely in the bin.
Any food scrapings and pizza toppings can be put in the brown bin.
