I accidentally just posted a very similar question in MRc7 and Tristan tried clarify (thanks Tristan). I figured I would follow up in the correct credit...

The reference guide implies that remanufacturerd toner cartridges are an appropriate way to acheive this credit...but which sustainability criteria do they fall under? Especially if they use previously used pieces for their intended purpose as our vendor reuses toner casing, amongst other things. LEED's definition explicitly states items cannot be reused for their intended purpose.

Any clarification would be great. Tristan, maybe this helps clarify my confusion. Sorry for the wrong credit post earlier.
