How much better are bio-based plastics than conventional plastics made from fossil fuels? Will Lego’s bio-based plastic bricks prove to be the way forward? Researchers from Keele University discuss.
Lego is going to start making toys from plant-based plastic. In an effort to become more sustainable, the Danish company announced plans to make tiny plastic trees and bushes for its playsets using ethanol extracted from Brazilian sugarcane. Yet while this looks like a forward thinking move, these toys represent just a tiny proportion of Lego’s overall production. And, what’s more, plastic made from plants really isn’t that sustainable.
