These Green Billboards Breathe in Carbon Dioxide
I don’t think I have ever been sold on anything like Omaha Steaks or watching Transformers 3 after seeing a billboard for it, but these new green Coca-Cola signs can do more than serve as blaring advertisements.
Coca-Cola and the World Wildlife Federation unveiled the first “living” billboard in the Manila, Philippines last week. The green bits around the coke bottle are thousands of Fukien tea plants spread across the 60-foot-by-60-foot canvas. Each plant can absorb 13 pounds of carbon dioxide annually, for an total of 46,800 pounds of carbon dioxide absorption.
If that isn’t enough eco-friendly points yet, the whole thing is made of recycled materials. The planting pots are made from recycled coke bottles, while the potting soil is made up of industrial byproducts and organic fertilizers. To water and nourish the plants, the billboard is fitted with an efficient trickle-down irrigation system.
There’s no word if these billboards will be making it stateside, but if this greenery siding could be applied to buildings and skyscrapers it could help keep downtown San Francisco or the literally treeless Tokyo cooler. (Not that San Francisco needs to be cooler with all the fog, but still.)
