Toymaker Lego to stick to its quest to find sustainable materials despite failed recycle attempt

N.B. woman builds toward LEGO record LEGO enthusiast Faith Howe has set her sights on a Guinness World Record.

COPENHAGEN, Denmark — Denmark's Lego said on Monday that it remains committed to its quest to find sustainable materials to reduce carbon emissions, even after an experiment by the world's largest toymaker to use recycled bottles did not work.

Lego said it has "decided not to progress" with making its trademark colourful bricks from recycled plastic bottles made of polyethylene terephthalate, known as PET, and after more than two years of testing "found the material didn't reduce carbon emissions."

Still, the toymaker remains "fully committed to making Lego bricks from sustainable materials by 2032," it added

Two years ago, the privately-held group which makes its bricks out of oil-based plastic, started researching a potential transition to recycled plastic bottles made of PET plastic, which doesn't degrade in quality when recycled.

It had invested "more than $1.2 billion in sustainability initiatives" as part of efforts to transition to more sustainable materials and reduce our carbon emissions by 37% by 2032, Lego said.

The company said it was "currently testing and developing Lego bricks made from a range of alternative sustainable materials, including other recycled plastics and plastics made from alternative sources such as e-methanol."

Also known as green methanol, e-methanol is composed of waste carbon dioxide and hydrogen, created by using renewable energy to split water molecules.

Lego said it will continue to use bio-polypropylene, the sustainable and biological variant of polyethylene -- a plastic used in everything from consumer and food packaging to tires -- for parts in Lego sets such as leaves, trees and other accessories.

"We believe that in the long-term this will encourage increased production of more sustainable raw materials, such as recycled oils, and help support our transition to sustainable materials," it said.

Lego was founded in 1932 by Ole Kirk Kristiansen. The name derived from the two Danish words, leg and godt, which together mean "play well." The brand name was created unaware that lego in Latin means "I assemble."
