Plastic pot yoghurt, pudding
PMD
Yogurt pots belong in the blue PMD bag. They are plastic containers (the P of PMD), which are perfectly recyclable. Make sure they are empty before you sort them. There is no need to rinse them. Preferably don't stack them together either, because then they won't be recognised by the sorting machines and will be lost for recycling.
If the sealing of the pot is completely in plastic or aluminium, you can also sort it in the blue bag.
TIP: does the pot have a so-called sleeve in carton, covering the 'body' of the pot? You can easily rip this sleeve open and sort it with the paper-cardboard waste.
