  • IIRC the energy differences are negligible between recycling glass and new glass, and it's not like we're running out of sand in the world.
    That's not just it. I'd prefer not to fill the world with broken glass bottles, if you don't mind.

    What always surprised me is why "they" seem to be so reluctant to recycle metal. Surely, cleaning up metal out of metal objects can't be harder than mining and cleaning it up for the first time, can it?

    • I was told (so this is just a rumour being repeated) that, because of the original OPEC oil price cartel causing much higher shipping prices, Japanese car companies switched to using a much higher proportion of recycled steel in the 80's for a while, but then they switched away from that because of a much greater tendency for the body to rust on those cars. (The story was told to me in the early 90's when I was commenting to the owner of another Toyota that his had the same sort of wide-spread rust as mine, with bubbles of rust under the paint growing big enough to eventually burst.) If true, that would mean that the recycled steel had things mixed in with it that were harder to separate than the material that comes with natural ore deposits.
