Where do you recycle your RO/DI filters?

Hi everyone,

I recently came across how you can recycle your old Brita filters. I was wondering if you could do the same with RODI filters.

I think, they're extremely wasteful if I were to just chuck them into the landfill, even though I admit that I have done so twice now...

I couldn't find anything on the web. Thank you in advance. I was also thinking of asking starbucks or some other coffee shop that also uses RO/DI for their coffees, and what they do with theirs. If they recycle theirs, then I will try to attain a number in the lower mainland.

Thanks!
