Re: Interesting point! formalin separation from tissues for disposal
I think I would be looking for another job if I had to deal with your safety people. They need something better to do.
For the record, we separate, then neutralize here. At Shady Grove Adventist they separate and ship for incineration.

You and I are in agreement. I, like you.consider the lipid in the
formalin to be a colloid for lack of any better term.it is commonly
found floating on the surface of the waste formalin. this is where I'm
at now. the Safety people want it (lipid) out but can't offer any advice
on how to do just that and of course, I will consider any method that
creates additional safety concerns for staff and another full time job
to accomplish, undesirable.
re: Carrie's suggestion, neutralization followed by drain disposal
would not be acceptable at my facility. in fact, this would probably
cause me greater headaches as I would have to prove that no formaldehyde
remained in the waste before disposal could occur.
I'm hoping someone will have a reasonable suggestion for what has
quickly becoming a crisis as they are not allowing me to do any
additional disposal of tissues or waste formalin until a solution is
found. we don't have the space to permit this stuff to accumulate.

Hazel brings up a good point. Next question, is what do you do with
separate blood and lipid waste? Has your safety people thought of that?
do you have a way to dispose of these in another manner?
Maybe looking into formalin recycling would be a good choice, since
have to do so much work to satisfy the safety people. Then the only
you have to dispose of is what is left in bottom of recycling unit,
by comparison to volumes of formalin. Personally, I don't think one
separate lipid out totally, it makes a colloidal solution (hope I am
thinking correctly here) and I am sure everyone has seen cloudy
from very fatty tissue - and if you can't get it all out, what does
safety people make you do then??
