As part of an environmental initiative, LEGO is testing different materials and solutions to replace the A. B. S plastic that the bricks are currently made from.
Alternatives to plastic include recycled materials, as in the case of the PET bottle prototype, or bio-based materials such as sugar cane.
There are several technical challenges when using recycled PET:
◾ recycled material is softer than ABS plastic and modifiers have to be used
◾ the colouring technology of the pads has to be changed because the PET material reacts differently with the dyes
The long-term goal is to have all bricks made from sustainable plastic by 2030, and to remove single-use plastic from all LEGO products and packaging by 2025.
Already the numbered bags containing the bricks are being replaced by paper bags.
