Autodesk Inventor - student licences

[Oops_my_bad]

We have a network licence for autodesk inventor, but the school also bought the student package with about ~50 student licences (and 50 copies of the software, which currently takes up my store room).

Can anyone suggest what i could do with these 50 copies? Sure we could give them out to kids, but when they install it at home the serial number has to be registered with autodesk, and then the software is useless for anyone in the following year that might want to use it

In a cardboard box and post back to Autodesk, on the grounds that the waste producer is responsible for proper disposal?
