Give your biggest "green" to the very FIRST #sustainable LEGO Bricks! LEGO botanical elements including leaves and trees will now be made from sugarcane-based plastic.The first "greens" are to appear in LEGO sets later this year.

It's part of the company's pledge to transition to using sustainable materials in Lego products and packaging by 2030. Creating plastic parts from sugarcane -- called 'bioplastics' -- isn't a perfect solution, as that crop still requires a lot of farmland, and growing more could cut into land allocated for food production. Further, the historical demand for sugarcane has degraded tropical forests and coastal wetlands; More demand could lead to further deforestation.

Changing the Lego recipe from acrylonitrile butadiene styrene (based on crude oil) to a plant-sourced plastic is certainly a more sustainable choice. And though sugarcane isn't a perfect source for bioplastics, it's a first step toward making your favorite building toys (and future domestic caltrops) a little greener.
