Lego believes there’s no universal definition of “sustainable material”. They partnered with WWF to reach a definition of what is sustainable.
Lego plans to use renewable ethanol in all its polyethylene (PE) designs and to use sustainable materials in all its core packaging and products by 2030.
Lego will exclude biodegradable plastics as they’re afraid the plastic may brittle and compromise safety, quality and durability.
Bistra Andersen, senior product manager for materials at Lego said
“We don’t want degradation to happen … for many reasons … So our focus is on the input side. We believe in durable but not biodegradable materials; we take a cradle-to-cradle approach. Due to internal analysis we have found that most CO2 [carbon dioxide] emissions come from upstream [parts of the business] and most [responsibility] lies with the polymer producers. We do want to use more renewable energy and sustainable products in production.”
