What?
Fake Christmas trees are made of many types of material which generally renders them unsuitable for recycling.
Many trees of this type are reused over and over and the most sustainable tree for your house is the one you already have – so if you already have one of these, keep using it!
Where?
If you can separate out some parts of the tree into just plastic then those pieces can go into the recycling bin. Mostly though, materials are difficult to remove from each other and, when beyond repair, should be placed in the general waste bin for disposal.
