The pizza container should be thrown away with the paper, like a normal packaging box. If instead it is soaked with food residues and pieces of food, there are three operations to do:
- the food remains go in the wet collection;
- the clean lid - which usually is not touched by the pizza - should be torn off and put in the paper container;
the part of the container smeared with food should be reduced in size and placed in the undifferentiated bin - only if certified compostable can it be placed in the wet bin.
