[Histonet] recycling solvents

Hi Gudrun:
I never recycled ethanol because it takes too long, uses too much energy, and the final product is never 100% pure.
On the other hand I recycled xylene which a less time consuming operation, cheaper and renders a product that can be used directly in the tissue processor.
I used to recycle an average of 2,782 liters/year (about 11 liters/day).
The re-payment ratio was $537/month and at that rate the instrument (a B/R recycler) paid itself in 30 months.
The disadvantage is that you have to protect yourself from xylene fumes during recycling and this is one of the reasons why xylene should be totally substituted by 2-propanol in the general operation of the lab.

Hi all!

What is the general opinion about recycling ethanol and xylen?  Experiences?
Reasonable volumes?

I would be glad about any comment.
