And I would echo Ellen’s experience with CBG solvent recycling systems – we use it to recycle acetone from teaching labs.  We use the 2.5 gallon capacity recycler and it runs every day.  We’re able to divert 100’s of gallons of acetone from our waste stream and save many $’s in purchased acetone.  We are most definitely a LQG.


I know the system is capable of recycling a number of common solvents to technical grade.  I think if you ran the product through the machine a second time, it’d be close to reagent grade.  We don’t have those purity requirements in this application.


It’s an elegant system – all gravity fed and self-contained.


I have no economic interest in or technical relationship with this company.

Hi everyone,

A couple of years we had a group work with a company to see if they could purify some solvents and reuse for their own purposes.. They ended up purchasing the recycling unit, to the tune of $20,000. But, they reduced the volume of spent solvents they were generating by quite a bit.

This goes into our Waste Minimization report now. We are also a LQG. This process is exempt from the waste regulations. But, I would clarify that with your state, just to be sure.


Good Luck!
