Can you reuse the filtering particles of a zero water filter?

I have saved all my zero water pitcher cartridges, cut them open and emptied out the carbon and other particles from the filters and have them stored in a bucket. Is there any way to disinfect/clean/other in order for me to put them in a container or strainer, etc. and reuse these filtering items. I know it may not be as clean as the original, but using 15+ filters, I have quite a lot of "particles" and would think in an emergency situation, could come in handy. I would not mind using coffee filters and other items in conjunction, and even thought about putting them in plant containers to help filter out bad stuff for especially herbs and vegs. Opens up a lot of possibilities, I know. Tell me to take a hike (I can use the exercise) if not doable.
