Tubeless toilet paper: Why didn't I think of that?

It's easily the biggest bathroom tissue news in 100 years. From USA Today:

On Monday, Kimberly-Clark, one of the world's biggest makers of household paper products, will begin testing Scott Naturals Tube-Free toilet paper at Walmart and Sam's Club stores throughout the Northeast. If sales take off, it may introduce the line nationally and globally -- and even consider adapting the technology into its paper towel brands. No, the holes in the rolls aren't perfectly round. But they do fit over TP spindles and come with this promise: Even the last piece of toilet paper will be usable -- without glue stuck on it.

The environmental angle: A total of 17 billion toilet paper tubes are produced annually in the U.S., accounting for 160 million pounds of trash. That's more than a million miles placed end-to-end. "It's a positive example of how companies are seeking creative ways to reduce environmental impact," says Darby Hoover of the Natural Resources Defense Council.
