How do I recycle my old cup?

In many cities in Europe, if you bin your old cup, its burned along with other waste and energy is created from the heat. So you can ask at your local recycling facility, as they will most likely know what to do with medical-grade silicone - perhaps they might even able to take it in themselves. If you don't want to throw your cup in the bin, a way of disposing your menstrual cup is to burn it. You can do so worry-free because silicone is basically sand (quartz). It will only produce a tiny bit of CO2 due to the small quantity of silicone used for the cup.
