Old Pumps, what to do with them?

I have the following items and I no longer use them. Can I donate them or recycle them?

  1. Dexcom G4 Receiver

  2. TSlim G4 Insulin Pump S/n 483361

  3. TSlim X2 s/n 561528

  4. Animas Pump s/ 48-40317-15 with a OneTouch Ping blood glucose monitor.

If anyone is interested in any of these let me know.

I have 5 insulin pumps that I promised myself I would use if my current one failed. But I’ve never touched them and I have no supplies for the. And I can’t get rid of them. I don’t know why.
