How to recycle plastic plant pots
Many local authorities collect pots, tubs and trays in their kerbside collections. If your local authority does, then you should be able to put non-black plastic plant pots in your home recycling collection - it is best to check with them directly.
Some garden centres offer plant pot take back schemes.
Currently black plant pots contain pigments which make them undetectable to the sorting machinery used to sort plastics, unlike other pots, tubs and trays used for food packaging, so need to be placed in the waste bin.
