Sprint's first phone made partially of corn-based plastic, the Samsung Reclaim was announced yesterday, but the manufacturer and carrier aren't stopping there, executives told Gearlog.

Samsung announced a flagship eco-phone called "Blue Earth" at Mobile World Congress back in February. Blue Earth had a built-in solar panel and was made in part from recycled water bottles. While Blue Earth may not be coming to the US soon, Samsung's senior vice president for strategy and product management Omar Khan said Samsung is assembling a range of eco-phones from a "menu" of eco-friendly options. For instance, the company now has a solar phone available in India, he said.

"There is a commitment from Samsung to roll out further eco-centric products," Khan said.

Sprint is committed to going beyond the Reclaim too, said David Owens, Sprint's director of consumer marketing.

"We're going to have minimum standards of eco-friendliness for all devices, plus a couple of hero products," Owens said. "We want to try to make the statement that we're the most eco-friendly wireless carrier."
