and Lego, which doesn’t make any non-plastic products, is looking into plant-based plastics for its production lines.

In 2015, a group led by the University of Georgia environmental engineer Jenna Jambeck estimated that somewhere between 4.8m and 12.7m tonnes of plastic was entering the ocean each year, a number they expected to double by 2025.

“At Lego we want to make a positive impact on the world around us, and are working hard to make great play products for children using sustainable materials” said Tim Brooks, vice-president of environmental responsibility at the Lego Group. “This is a great first step in our ambitious commitment of making all Lego bricks using sustainable materials.”
