Question: how many clothes hangers does it take to create carbon reductions equivalent to removing 1.5 million cars from the road? It's something none of us might have pondered had it not been for Nick Lewis, a British inventor and owner of Hanger4Life, whose Adjustable Eco Hangers were applauded by InventorSpot this weekend. The lowdown after the jump. Made of strong ABS plastic (the kind used to make crash helmuts), Adjustable Eco Hangers use 40 percent less carbon than normal hangers in their production through more efficient manufacturing and reduced packaging. Lewis vows to supplant the carbon Hanger4Life does expend by planting trees, thus earning the hanger its much talked-about carbon-neutral status. Plus, the hangers are adjustable—as kids grow, their hangers grow with them, reducing waste that might otherwise end up in landfills. Whether Lewis fulfills his goal of circulating 40 billion hangers a year worldwide (for a reduced carbon emissions of 6.5 million tons annually) is something that remains to be seen.
