Lego has been testing making some pieces out of corn-based plastic or other natural plastics. https://www.lego.com/en-us/sustainability/sustainable-materi...
replySome of the first forays resulted in notably lower-quality bricks.
lego compatible bricks made from wood do exist. they probably don't last as long though.
