Coca-Cola has introduced a new yellow cap for its bottles
The yellow cap is part of Coca-Cola's World Without Waste initiative
The initiative aims to make all of Coca-Cola's packaging recyclable by 2025
The yellow cap indicates that the bottle is made from 100% recycled plastic
Coca-Cola hopes that the yellow cap will encourage consumers to recycle more
The yellow cap is currently being rolled out in Europe, with plans to expand to other markets
