Disposing of used filters

The filter would need to be smashed the ceramic and media inside should go to rubbish and the plastic ends can be recycled as plastic. Some people use the media and ceramic to compost but I don't because they can have pharmaceutical and hormone traces and I grow food so I would not want that. For the media, it would be best to send that stuff to the landfill.
