[Histonet] Histonet Digest, Vol 94, Issue 40 Nothing down the drain

[Steve McClain]

Yes nothing down the drain (except maybe the lithium carbonate bluing).

Hematoxylin goes into medical waste service.

Used Eosin gets reused a 10-20 ml at a time into the first absolute on
the processors as a marker of carryover (as the later alcohols turn red,
we have a visual indicator of the need to change, also helps with
embedding since collagen stains more than epithelium/epidermis).

Alcohols after the de-waxing xylenes and from the processor purges go to
the medical waste service.

Other alcohols get recycled.

All the Xylenes get recycled.

Liquid Waste from the recycler goes to medical waste service.

Paraffins go into the trash.
