I think what he meant is that what how one would dispose of these carcinogens once they are extracted would be harmful, as in would you just "throw them away" or could that have an impact on the environment depending on how it is stored/cleansed. But your solvent solution might have some merit, although again I don't know the properties of acetate cellulose enough to know if it would remain intact after having said solvent run through it. Also since I wanted to do this under the idea of using it as a growing medium for plants:
1) Would this solvent chemically contaminate the acetate cellulose?

Likely. There are solvents you could use that wouldn't affect cellulose acetate but I'm not sure about their suitability to extract the tar... suitability in terms of solving one problem and creating a much larger one.

Plant roots are very effective at absorbing trace elements of substances and anything leftover could be harmful, or interrupt the plants ability to absorb the other nutrients it needs (N,P,K,Ca,Mg, ect.) in order to function.
2) Even if it didn't contaminate it (and we were left with just the purged filters), would the structure of acetate cellulose inherently have trace elements in its structure that would be toxic to the plant, or again, interrupt its uptake of the other elements it needs for nutrients?

I guess it would depend on the plant and the growing conditions. Will the plug be in contact with the soil or will it be grown hydroponically?
