The refill is not currently recyclable but is biodegradable. You can put it on your compost heap or if you don't have one, it goes in general waste.
Wherever you dispose of it, the refill will decompose within a couple of years and will not release any nasty chemicals that damage the environment. 🌿💚
This is a much needed step in creating packaging that isn’t going to stick around on our planet for years to come.
