Five gallon (20 Liter) polypropylene plastic carboys (jugs) are used on campus for collection of waste organic solvents, their solutes and some aqueous solutions of toxic organic chemicals. If you need a carboy for your waste organic solvents, contact Chemical Waste Management for delivery to your room.
What is a Solvent Carboy?
A carboy is a 20 liter, square, plastic jug that is given out by the Office of Chemical Safety for use as a collection container for used lab solvents.
How do I get a Solvent Carboy?
Fill out the required information and how many solvent carboys for drop off that you’d like on the Chemical Waste/Surplus Pickup Request Form.
What color/type of Solvent Carboy do I need?
The carboys for non-halogentated waste solvents are white. White Square carboys are used for collection of waste solvents such things as alcohols, acetone, acetonitrile, toluene, etc.suitable for fuel blending. These include non-halogenated flammable solvents such as acetonitrile, ethyl acetate, hexane, methyl alcohol and toluene. Low halogen content solvents (i.e., chlorobutane, chlorobenzene) can be included. Amines should be excluded from this collection. Follow the Guidelines For Using Carboys.
The carboys for halogenated waste solvents are yellow/orange. Yellow/orange, square carboys are used for the collection of solvent wastes that must be incinerated specifically for destruction at 99.99% level (i.e., to carbon dioxide, water and hydrogen chloride) with scrubbing for hydrogen chloride. These include halogenated solvents such as chloroform, dichloromethane (methylene chloride), Freon 113 (trichlorotrifluoroethane) and trichloroethylene. Follow the Guidelines For Using Carboys.
What do I need to do when my Solvent Carboy is full?
- Fill out the required information and how many and what type of solvent carboys you want picked up and/or swapped out for empty ones. Use the Chemical Waste/Surplus Pickup Request Form.
- Fill out the Chemical Inventory of Waste Solvents in Carboys Form for each full carboy and keep them with the carboys for pick-up.
