Kimberly-Clark takes a big green step with the launch of its new tubeless toilet paper roll for the Scott Naturals Brand. The new product goes without the TP roll's cardboard tube, making an automatic, tangible improvement to the overall waste pool. According to the company, U.S households use an estimated 17 billion tissue tubes a year, the equivalent of 160 million pounds of trash, or, about 250 Boeing 747s. Add to this the fact that the tubes are often overlooked in the recycling process and that makes for a lot of waste. The product is now being tested in the Northeastern U.S. at Walmart and Sam's Club stores.
