@Phantomlink, Ozpin's long lifespan is more likely attributed to his Aura, rather than Dust. In WoR: Aura, a silhouette of Ozpin was displayed while the narrator said "With enough training and focus, a user's Aura can turn them into something much more than just a man."

@Spartacus, True. Though, Dust being nonrenewable would be one explanation for why the narrator said at the end of WoR: Dust "Despite working, fighting, and even turning a profit with it, humanity has still yet to understand how Dust came to be, and more importantly, how their involvement with Dust will ultimately change the world of Remnant." I guess another explanation would be that using Dust creates pollution or something? I dunno.
