The new figure comes from a study by the Environmental Protection Agency. This includes all plastic being thrown away, including that from factories and farms.
The EPA says there is a lack of systems to allow building firms, industrial operations and hospitals to separate plastic from other waste. In addition only a minority of local municipalities have places to collect plastic items such as old garden furniture or plant pots.
It warns that burning plastic is making it harder to reach the climate goal of zero net emissions by 2045 at the latest.
