McDonald’s U.K. has unveiled plans to release a range of ‘sustainable’ Happy Meal toys. This new move comes in an effort to reduce the number of hard plastic toys found in the United Kingdom each year, an initiative that is yet to reach the U.S. market.

With Disney’s upcoming release of ‘The Lion King’ remake, the new range of toys will be themed around this movie. The ten different toys will each represent one of the movie’s characters, including Simba, Nala, Timon and Pumba.

The next six months will act as a trial period for McDonald’s U.K., who are looking to implement a broader ethos of sustainability. U.K. restaurants will provide other options to customers in addition to the sustainable toys to figure out what customers in that particular market want. McDonald’s have said that they are also working on a global solution that is consistent with its “overall Scale for Good packaging and recycling goals.”

The company said, “We have an active global working group exploring the production of more sustainable toy options. While we cannot provide details of our Happy Meal promotion beyond the end of 2019 at this stage, we remain committed to reducing plastic across our business.”

McDonald’s currently operates around 38,000 locations in over 100 different countries.
