I doubt it's a major issue, but some chemicals will build up over time if I recall correctly and should be removed from the cycle altogether, if possible. But I also like to think (and this is all unscientific gut feeling) that processing it in compost and exposing it to the elements and UV sunlight helps break down everything. Entropy, or my probable misunderstanding thereof.
