There should be no issue with moving the butyl lithium to your waste 
storage area as long as the container is in good condition.  I don't see 
why this is even in question.  That said, I also don't see why your 
waste contractor would charge extra to collect it from a lab.  I 
wouldn't, and don't know other hazardous waste contractors that would 
either.

Subject: [DCHAS-L] Disposal of butyl lithium

Responses from users in MA and other states not permitting treatment of 
hazardous chemicals to inactivate prior to disposal of particular 
interest

One of our chemistry labs has butyl lithium that they no longer use and 
are trying to safely dispose of.  Massachusetts state law does not 
permit any treatment of hazardous chemicals to inactivate prior to "safe 

disposal".  Our normal process is to transfer any hazardous chemicals to 

an isolated and dedicated room.  We have a contract with a local 
company, skilled in hazardous materials, and trained personnel from that 

company then remove the chemical waste.  The PI feels that moving the 
butyl lithium to the waste facility would be more, rather than less, 
dangerous and has requested that we have the butyl lithium removed 
directly from their laboratory.  The latter, of course, is expensive and 

the hazardous waste company suggests that if the butyl lithium is still 
stored as received and should be stored in water-free hexane, then it 
can be brought down to the holding facility.

Any experience or recommendations?

Thanks,

dona wong
