In Florida we need to keep blocks only during 9 years. Every year we disposed those kept for 9 years and started a new series (using the same cabinets).
Other states may have different regulations.

I know this subject has probably been addressed before, but I need to poll the
We are a Pathology Core in a research center.  We have paraffin blocks (mostly
non-human) collected since we were established in 1986.  Our core will soon be
undergoing renovation and we need to either store or dispose of a good many of
these blocks.  It will be expensive to store all these blocks and, since most
them have never been accessed again, we would like to destroy them.
I would like to hear back from other people as to what their policy is,
especially in a clinical setting.
Thank you.
