Boise State Begins Solvent Recycling

Boise State Begins Solvent Recycling

Boise State’s Environmental Health, Safety and Sustainability (EHSS) team recently partnered across campus with the Boise State Chemistry Department to work towards better sustainability with regards to solvent waste and use on campus.  The two departments partnered up to purchase equipment that will take solvent waste and distill it into useable high grade solvent and a separate collection of waste.

EHSS estimates approximately 50-percent of the volume will be recovered as usable solvent, reducing waste and creating reusable solvent for use in labs at the same purity level as it is purchased.

EHSS and the Chemistry Department are still evaluating the equipment and the purity, and will be working on a model in order to sell this material back to the labs at a reduced rate.  Funds generated will be used to purchase a second solvent recycling unit for use in the Engineering Department.

In this example waste acetone is generated and collected in a lab.

It is poured into a 5 liter chamber that is connected to the recycling equipment.

The chamber is placed in position, a few buttons are pushed on the control pad and within 4 hours the process is complete. No odors, no vapors, and no external heat. The bottom chamber in this photo shows clear clean solvent that has been recycled.
