Q: If I am recycling more than one solvent in a recycler, how do I avoid cross contamination between the solvents?
After making your solvents nice and clean in the recycler, you don’t want to contaminate them with another solvent.
Recycling with B/R since 2014
Quest Diagnostics is focused on making their labs more sustainable by recycling their solvents. In 2014 they recycled over 1352 gallons (5,000 liters) of solvents!
That is over 122 metric ton reduction in their carbon dioxide foot print.
While helping the environment, they also saved over $24,000 USD in solvent purchase and disposal costs in just one year.
You can only imagine the impact if every lab got serious about sustainability.
Q: How do I fill my recycler?
Most recyclers have more than one way to fill them. You can choose the fill method that fits your lab.
Q: My boss wants our lab to start recycling solvents. How do I know if it makes financial sense?
Solvent recycling saves money! That’s the main driving force for recycling.
Q: How many years will a solvent recycler last before it needs replacing?
10 to 15 years or…Longer.
Do you remember your cell phone from 15 years ago?
Q: Do filter based recyclers work?
Yes and no….mostly no.
There are commercial filter recyclers available for alcohol and formalin. There is not filter recycler for xylene on the market.
Older solvent recyclers worked great but used condensers cooled by water.
Today’s solvent recyclers use condensers cooled by air. So no water or drain is required.
You win because the workplace is safer.
The facility wins because you are saving money
The environment wins because you’ve cut your waste solvent generation by 95%.
Q: Our lab wants to switch to xylene substitutes. Can they be recycled?
Actually, xylene substitutes are easier to recycle than xylene. Their higher boiling points make it easier to separate from the contaminants.
A well-designed recycler can recycle a solvent forever!
Solvent used for tissue processing or staining becomes contaminated with stain, water, fat, protein, wax, and biological materials during use.
The recycling process removes these contaminants from the good solvent. Reuse of the solvent is unlimited since it is brought back to the original purity each time it is recycled.
