Is there any way to recycle your Detox dechlorinator?

The activated Carbon inside the Evolution Aqua Detox de-chlorinator itself isn't classified as special waste under UK Special Waste Regulations 1996 and can be disposed of by landfill at an approved site or general waste bin. So, the carbon can be disposed of in your general waste bin, and if you wish you could recycle your empty plastic shell into the appropriate plastics recycling bin.
