It's the comeback campaign that's got Coca-Cola in a fizz. SodaStream, the do-it-yourself soft-drink machine has launched car-sized cages around the world filled with used soft-drink bottles and cans. Their message - buying packaged drinks clogs up landfill, while making soda at home helps save the planet. Daniel Birnbaum is Sodastream chief exectutive. (SOUNDBITE) (English) SODASTREAM CEO, DANIEL BIRNBAUM SAYING: "Even if we had a 100 percent recycling rate, the bottles and cans still have to be produced. Do you know how much oil goes into their production? 100 million barrels of oil per year. That's a lot. The BP oil spill was 5 million barrels and we couldn't help it. But here humanity is spending 20 times more on something we are saying you don't need. Coca-Cola wake up. You don't need the bottles and cans. Figure out a way to do it where you don't need to recycle." But it's a display similar to this in a South African airport that has led to threats of a lawsuit from Coca-Cola. The world's largest beverage maker told Reuters it is committed to reclaiming its packaging and ensuring it gets recycled. Coca-Cola is around 228 times bigger than SodaStream, but the company says it's not prepared to backdown. (SOUNDBITE) (English) SODASTREAM CEO, DANIEL BIRNBAUM SAYING: "Recyling is also an energy consuming business. Factories have to process, crush, and then they are shipped to china for fleece. Recycling is overrated, and that message needs to be told. And we're telling it. No one is going to stop us. Not with a lawyers letter." SodaStream was a common sight in homes around the world in the 1980s. The bottle installations coincide with a revival from the Israel-based company, which recently had a breakthrough in the American market, with retail giant Walmart agreeing to stock its products.
