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