Many Christmas decorations are made of a combination of materials which sometimes renders them unsuitable for recycling.
Any old decoration made from paper, card or rigid plastic only can be placed in the recycling bin.
If you are not sure what the decoration is made of or unsure if it is made of multiple materials then place the item in the general waste bin.
If a decoration has a battery, remove battery separately for recycling.
Reuse your decorations each year or perhaps swap then with friends.
