Lego has been searching for a sustainable alternative to plastic since 2015, and it has found a solution in sugarcane fields. Yesterday, the company said it has started production on a new line of Lego elements made from plant-based plastic sourced from sustainably grown sugarcane. The toys are made from polyethylene derived from the plant, but, according to a press release, “are technically identical to those produced using conventional plastic,” meaning they will probably still hurt like hell to step on.
