OK so it's not the whole stadium... The recycled plastic bottles will be used in the linings of the seats in the new Maracanã Stadium, which will host the final of the 2014 FIFA World Cup in Rio.
One of the main sponsors to the 2014 FIFA World Cup in Brazil, soft-drink company Coca-Cola has launched a new sustainability project to collect and recycle plastic PET bottles. To date 100 recycling points have been set up in Rio, which they hope will generate lots of recycled bottles - as well as get people excited about the football event.
A major drive behind this campaign is Coca-Cola's pledge to reduce the environmental footprint of the World Cup and boost the culture of recycling.
Take a look at Coca-Cola's video for the project here.
