ANSWER:

Throw it in the dustbin as its trash!

Thinking that the dust on the Quran of the haram has some special benefits is Shirk!

QUESTION: I had travelled for umrah few weeks ago and i cleaned the quran shelves with a wet wipe in haram and got back that tissue which had dust of that shelve as a souvenir. I was not aware of not carrying anything from mecca back home. What should i do with that tissue now? I did istigfar after knowing its haram.
