Histonetters,
We have been recycling formalin for some time with great success.  The
waste from the recycler contains 1% or less formaldehyde according to a
simple assay we do as QA on the recycled product.  I am exploring the
possibility of "neutralizing" this waste into something that doesn't
have to be carted away at $5/gallon.  I'm familiar with Aldex, but I
recently heard about a product from Sakura that works immediately with
no standing time.  Your success stories and comments will be 
appreciated.
