A poster as part (follow up) of the campaign: "We've collected 100% of the plastic we introduced to the market".
HL: Transparent bottle. (A play on words: transparent/clean (new bottle made 100% from recycling).

The main part of the campaign: "We've collected 100% of the plastic we introduced to the market."

Bravo! For choosing bottles made 100% from recycling
