[Histonet] Paraffin Wax Waste Disposal

[Sherwood, Margaret]

We have to have our processor paraffin picked up as hazardous waste, since it
has traces of CitriSolv in it.

That's funny that you got cited for that.  I was surprised to learn what our
safety officer setup at my lab for paraffin disposal.  A commercial company
takes our paraffin and makes a product with it that is mixed with cedar
sawdust and paraffin wax for starting fires in the BBQ, fireplace, or
campfires, etc.  I wonder if consumers would want to use this product
knowing where the paraffin came from.  The company tested the paraffin and
said it's pure enough to meet their standards.  Just thought it was an
interesting so I decided to share.
