I have no idea, but my guess is that the cost of fuel would be an order of magnitude greater than any possible disposal costs.

Also, people pay good money for high-quality metals. The scrap value is probably greater than the logistics cost of getting it to a scrapyard.

You wouldn’t even need to scrap it. Cut it up and turn it into some mega silos for agriculture or materials suppliers. Or just set it aside and donated to the Smithsonian in a few decades…
