Will and Jaden Smith are launching a new line of flavoured water which they say will reduce waste and slash carbon dioxide emissions.

The singer and actor’s JUST Water brand uses paper and plant-based material to create its fully recyclable boxy bottle, which it claims has a 74% lower emissions footprint than a standard heavyweight plastic bottle.

The cap is also made from sugarcane, which absorbs carbon dioxide from the atmosphere while it is growing.

The bottle has a wide mouth to encourage people to easily refill it from taps instead of having to buy a new one.
