Earthsaver clothes hangers, made from corn
Earthsaver hangers are made from a bioplastic sourced from 100% corn. They are 100% compostable and are made in the USA. According to Sustainable Is Good, Wal-Mart is carrying the hangers for $3.50 for a set of five, considerably more than your average pack of plastic hangers, which you can often see for a dollar or so. However, their design is supposed to be "heavy shirt" friendly, so the added eco-friendliness is not the only benefit.
There is some doubt about the ability of these hangers to be recycled, according to Gary Barker of Greenheart Global via Apartment Therapy. Also, if they do end up in a landfill, according to Baker, they will last just as long as a conventional plastic, over 1,000 years before degrading.
