In 2010 SodaStream launched an international campaign to raise awareness of bottle and can consumption. The campaign involves the display of 9-cubic-metre cages in various countries, each containing 10,657 empty bottles and cans. Begun in Belgium, the Cage campaign has since visited 30 countries with the message that the waste produced by one family over the course of five years from beverage containers – 10,657 bottles and cans – can be replaced by a single SodaStream bottle. When a cage went on display in Johannesburg , South Africa in 2012, Coca-Cola demanded that SodaStream remove its products from the cages and threatened to sue SodaStream. SodaStream responded by dismissing the threats and announcing that it would display the cage outside Coca-Cola's headquarters in Atlanta .
