27 Sep 2023 --- Danish toy producer Lego is ditching plans to convert its material feedstocks to recycled PET (rPET) after finding that the move would increase its carbon emissions. The company currently uses acrylonitrile butadiene styrene (ABS), a fossil-based thermoplastic, for its products. But after two years of searching for more sustainable material, the company has ended its quest, opting instead to attempt to improve the footprint of its ABS, which currently requires around 2 kilograms of oil to produce 1 kilogram of plastic.
