A report released on Tuesday by environmental group Greenpeace found that Coca-Cola, PepsiCo and Nestlé are the world’s largest producers of plastic trash.

In its report, Greenpeace noted that the most common type of plastic found was polystyrene, which goes into packaging and foam coffee cups, followed closely by PET, used in bottles and containers.

All three beverage companies have made pledges about their packaging. Coca-Cola said all its packaging will be recyclable by 2030. Nestlé said it will aim to be 100 percent recyclable or reusable. And PepsiCo said it will be recyclable, compostable or biodegradable, and the company recently joined the NaturALL Bottle Alliance.
