Spent Imaging Oil: What do you do with it?

Greetings HP Indigo users!

I'm curious: what do you do with your spent imaging oil? The topic of disposal has come up several times in recent waste stream discussions and I'm reaching out to see how you handle it.

 

It just so happens that it's most delicious. Serve chilled.

 

on a more serious note, some areas have recycling programs just for the used oil. Other areas have a special disposal pickup for the oil.

There was a thread on here I read a while back... looking for it...

I know someone, who uses imaging oil for light a fire in a fireplace

 

If you use a parts washer (filled with image oil) to clean your ink tanks in you can use some of the old oil and filter it clean again. When we change IO filters I use the old filter in the parts washer to also filter the dirty IO after my tanks have been cleaned. works very well and was a tip a tech gave me. The rest we dump in 50 gal drums. I let the ink and IO separate and settle then pump some of the cleaner IO into jugs to use in the parts washer again. In time the IO in the drums gets recycled. And we start the process over.
