[Histonet] mineral oil, paraffin, xylene substitutes and xylene
Actually, I have read the publication in J of Histotechnology. However,
the EXPENSE of collecting and incineration CJD contaminated material
remains the same regardless of being a solid mass or liquid disposal. The=20
point is the EXPENSE "the powers that be" are trying to avoid with
contaminated xylene. At least, that is how I read Phil's initial
inquiry. Unfortunately, this expense remains no matter what they use to
replace xylene although consolidation of paraffin and the oil may reduce
the overall amount to be carried away. They need to be prepared to pay for=20
hauling it away.
If we are going to be picky about spelling, "minaral" was just a typing

It is evident that you have not read the procedure!
Used minaral oil (= paraffin oil = paraffin of low molecular weight) is
MIXED with the used paraffin and together form a solid mass to be
incinerated after cooling.

Phil and Renee,
If the solvents i.e. alcohols, xylene or xylene substitutes need to be
collected for incineration after CJD cases, wouldn't mineral oil also need
to be collected and disposed of in the same way? The expense of collection
will still be there no matter what the powers that be do not like to
do. Mineral oil may be less toxic compared to xylene but after
contact.contamination with CJD or any other other prion diseased
tissues, it's status changes back to being a collectable solvent.
We work with prion diseased animal tissues using xylene substitutes (they
work very well for processing and staining) and we are REQUIRED to collect
these for incineration.
