Tanya, in our institution we don't treat intact paraffin blocks as a biohazard, but we do collect all trimmings from the microtomes and put in red biohazard bags. The reasoning is that no one outside the lab knows what this stuff is so we err on the side of the safety, or perceived safety, of those downstream in waste cycle.
