End of Life Instructions

We recommend reaching out to your local recycling facilities to see if they recycle medical grade silicone. If not, the best option is actually to burn the silicone outdoors. Burning silicone is rather safe since silicone dioxide is basically sand and glass. It will produce some CO2, but on a very small scale. Plastic cap and ring can go in the trash.
