G spent a lot of my lab life workign with orgnolithium reagents, and disposing of bottles of nBuLi such as you have, I would have no problem with transporting it as you would any other chemical: in a proper (i.e. Rubber-like container, preferably with a top in case it tips over.  The fact that it is dried up supports the thought that it is LiOH currently, but traces of dry BuLi is enough to cause problems with a break.  Lab pack the bottle at central waste, of course.

It is possible to quency such bottles, but the trouble and risk are not worth it.

Hi everyone,
I have a question that I’m surprised I cannot get an answer to through the normal channels.
We did a small lab cleanout this week and discovered a bottle of butyl lithium, 1.6M solution in hexanes. The hexane is completely dried up.
We’ve left it in the lab for now. But need to move it to our central waste storage site soon.
 
Is there a problem with transporting this material across campus?
