Living Green - Episode 75 - Self Cooling Can

Sue Wong Kill, a South Korean inventor, has developed innovative cans that can cool beverages within seconds of opening. These cans contain a small steel tank with a refrigerant and an aluminium coil that releases gas to cool the drink. The technology is cost-effective, adding only one cent to the cost of a regular aluminium can, and is environmentally friendly and safe for consumers due to its use of a harmless cord.

In what way is the can environmentally friendly?
