The candle has burned down?
How to dispose them propperly!

Paraffin: Since the raw material content of crude oil or fat in the candles is too low for recycling, they are disposed of in normal household waste.
Stearin: All candles made from animal or vegetable stearin (this applies to coconut, palm, soy & canola seed) cannot be composted and must therefore also be disposed of in the residual waste.
Beeswax: Beeswax candles also belong in the residual waste, as they are not allowed on the compost.
Regardless of which wax the candle is made from, wax residues should always be disposed of in the residual waste, which is burned. Wax residues are a welcome source of energy there.
Aluminum or plastic cups of lights must be disposed of in accordance with the respective municipal regulations.
Glass items must not be placed in the glass recycling container, unless they are beverage or food packaging; they must be disposed of as residual waste.
