How are Lego® bricks made? The Chemistry of LEGO® (2024)

I saw a Greenpeace advertisem*nt recently that lambasted LEGO® for its ongoing toy deals withShell Corporation. The advertisem*nt was dark,sarcastic, and tasteless.

The video, made to highlight the Danish company’s $130-millionrelationship with Shell, has reappeared on YouTube after being withdrawn last week following copyright complaints from the toy-maker.

The videomade me feel sorry forLEGO®. It also reminded me that LEGO® is made from oil-based products (even thoughthey’re trying to find a sustainable alternative), andit inspired me to makethis infographic: the Chemistry of everyone’s favourite building block.

How are Lego® bricks made? The Chemistry of LEGO® (1)

LEGO® is made from ABS (acrylonitrile butadiene styrene), a thermoplastic polymer comprised of three monomers. The first monomer,acrylonitrile, gives the bricks strength. The second, 1,3-butadiene,gives them resilience (i.e. stops them from snapping so easily) and the third, styrene, gives them a shiny, hard surface. These three ingredients are mixed with colorants then polymerised (hardened) with the help of an initiator called potassium peroxydisulphate. LEGO® buys pre-made ABS granules and injects them into brick shapes on a massive scale.

LEGO®make 20 billion brickseach year(that’s 35,000 bricks a minute)and according to the Guinness Book of World Records, theyproduce more plastic tyres than anyone else.Personally, I think that’s a remarkable feat. It’s engineering genius.

In a statement, LEGO® said: “We firmly believe that this matter must be handled between Shell and Greenpeace. We are saddened when the LEGO brand is used as a tool in any dispute between organisations.We will continue to… deliver creative and inspiring LEGO play experiences to children all over the world.”
