Coca-Cola tests the first bottle of paper

Prototype is made from a Danish company made up of an extremely strong paper shell that also contains a thin plastic coat.

The goal is to create a 100% recycled, plastic-free bottle, capable of preventing gas from coming out of soft drinks.

The plastic cork also needs to make sure that no thread can penetrate the liquid. This would pose a risk of changing the taste of beverages, or potentially losing control of health and security. But industry giants are supporting the plan. Coca-Cola, for example, has set a goal of producing zero waste until 2030.

Coca-Cola was ranked the world's number one pollutant by the charity group Break Free From Plastic last year, followed by other Peps and Nestle wine producers.

Michael Michelsen, the firm's business manager, says the bottles are formed by a single piece of paper-based material to give them strength.
