Plastic campaigners have accused Disney of hypocrisy for churning out plastic Frozen 2 dolls destined for landfill, while promoting an eco-friendly agenda.

With the second instalment of the popular children's film hitting screens ahead of Christmas, children are likely to hound their parents for plastic keepsakes, with some having already sold out.

But plastic pollution campaigners Friends of the Earth have criticised the toys from the film, arguing that they are at odds with the overall message, according to the Telegraph.

The first film saw the "Frozen Effect" made millions for merchandisers, with the licensing segment of entertainment and characters accumulating $107.2 billion.

Must-have plastic figurines which have been released to promote the film and are set to be under thousands of Christmas trees this year.

But environmentalists say that as plastic toys take up space in homes, they often end up contributing to the massive amount of plastic ending up in landfill and oceans.

Julian Kirby, plastics pollution campaigner with Friends of The Earth, told the Telegraph: “This film has pushed a strongly progressive narrative appealing just as much to parents as Elsa and Anna have to children.

"If the franchise wants to keep inspiring young audiences it should recognise that anti-pollution messages will chime with them far more than pumping out another predictable range of plastic destined for landfill.

"Disney has spoken about reducing their environmental impact so cutting out frivolous plastic would be a positive step on their way to sustainability.”

Recycling Association chief executive Simon Ellin warned against purchasing non-recyclable toys at Christmas.

Some of the most popular Frozen toys feature sound and light, which make them non- recyclable, the publication said.

Whilst we don't know exactly how much of the plastic that ends up in landfill comes from toys, green campaigners say that consumers can help reduce the amount in circulation.

Friends of the Earth says there are ways to cut back on buying plastic toys - like toy libraries, passing toys on, buying less, borrowing off friends and sharing more.
