Environmentally-minded travelers will be thrilled about a new “green” development at Chicago's O'Hare International Airport. A soil-less garden-- the first of its kind in an airport-- was unveiled at O'Hare last Friday. Located in the G Concourse of Terminal 2, the aeroponic garden spans 928 square feet. First planted in volcanic rock, the plants are then transplanted to vertical towers that are lit by special lamps and irrigated by a system that naturally recycles the nutrient-rich water that’s not absorbed. A bumper crop of Swiss chard, herbs, even red habanero peppers will supply four restaurants in the airport: Tortas Frontera, Wicker Park Seafood & Sushi, Blackhawks Restaurant and Tuscany. A joint project between the Chicago Department of Aviation and HMS Host (which manages the airport concessions), the garden is also a calm oasis for jetsetting travelers.
