They followed OSHA and DOT and WISDOT rules. My labs were all semi-micro, and we were a small school. So I kept two jugs going, with vapor locking funnel lids (I forget the brand name). One jug got all organic, not water soluble waste, except if it contained either Benedict's reagent or Biuret's reagent, both principally copper (II) sulfate. The waste recycling facility that the hauler delivered my waste to, wanted the copper sulfate separate.For each jug, there was a signing sheet. Each student dumping their waste wrote in the sheet what they put in, including the various solvent rinses prior to washing. So an organic jug entry might read: Josey Student, 2mL acetone (rinse) today's date,. Next line, Josey Student, 2mL linolenic acid plus drops K2Cr2O7 solution.I'd stand by the jug and help the first groups get it written correctly, then all the other lab groups could copy the first entry.I found it rather silly, but that's what the folks who took it away wanted, and failure to comply could result in a fine and them refusing to take it away without a costly assay. So, I made the sheets for the students to sign, I helped them know what to write, and I used it as teachable moments about doing the right thing even though it is annoying. We literally could have dumped every test tube down the sink legally because we were such a small school and I filled 1 4-Liter jug of organic waste a year, and 1 of the copper (II) sulfate waste every two years. But our local water treatment plant did nothing to remove the dissolved or organics that went down our drains, and after treatment the water is returned to the Mississippi River, so it gave me the opportunity to talk about being "green" even when not required to because it's the right thing to do for our Planet, and for the local habitats and environment.Hope everyone is staying warm. Supposed to go down to -14 Fahrenheit here tonight, and that's by the river. Where I am, up in the bluffs, it will be colder.

I work in academia and most of teh haz waste taht I generate are
mixtures that come from our courses. Because they all follow the same
set procedure and are using known chemicals, I know the contents and
teh hazards prior to the wste benign generated and therefore it is
very unusual for me to have to do any actual tests to characterize the
waste prior to shipping it out.
I have been determine the hazards of our waste based on the materials
we supply them for the experiment and even use the 49 CFR to include
the hazard class for most of the chemicals in these mixtures of the
Our new EHS person wants us to start logging each waste bottle monthly
on a form similar to the one here
Does anyone else do this or have any guidance for streamlining this process?
