There should be a centralised place on campus where staff, students and faculty can drop off old electronic devices, batteries, toner/printer cartridges, smoke detectors and other hazardous materials for reuse or safe disposal.
Tied into the idea of better asset management, the idea would be to have a store front where surplus items from around campus can be stored in (rather than stuffed into little rooms around campus taking up valuable space) and sold out of.
There are other Universities with programs along the same lines.
From LSE Environmental Policy 2011:
Use the zero-waste 'rethink-reduce-reuse-recycle' criterion in waste and resource management
