Lego, which sells billions of plastic bricks annually, has tested over 600 different materials to develop a new material that would completely replace its oil-based brick by 2030, but with limited success.
Now, Lego aims to gradually bring down the oil content in its bricks by paying up to 70% more for certified renewable resin, the raw plastic used to manufacture the bricks, to encourage manufacturers to boost production.
“This means a significant increase in the cost of producing a Lego brick,” CEO Niels Christiansen.
He said the company is on track to ensure that more than half of the resin it needs in 2026 is certified according to the mass balance method, an auditable way to trace sustainable materials through the supply chain, up from 30% in the first half of 2024.
“With a family owner committed to sustainability, it’s a privilege that we can pay extra for the raw materials without having to charge customers extra,” Christiansen said.
The Move Comes Amid a Surplus of Cheap Virgin Plastic
The move comes amid a surplus of cheap virgin plastic, driven by major oil companies’ investments in petrochemicals. Plastics are projected to drive new oil demand in the next few decades.
Lego’s suppliers are using bio-waste such as cooking oil or food industry waste fat and recycled materials to replace virgin fossil fuels in plastic production.
The market for recycled or renewable plastic is still in its infancy, partly because most available feedstock is used for subsidized biodiesel mixed into transportation fuels.
According to Nestle, the world’s largest producer of renewable feedstocks, fossil-based plastic is about half or a third of the price of sustainable options.
“We sense more activity and willingness to invest in this now than we did just a year ago,” said Christiansen. He declined to say which suppliers or give details about price or volumes.
Rival toymaker Hasbro has started including plant-based or recycled materials in some toys, but without setting firm targets on plastic use. Mattel plans to use only recycled, recyclable, or bio-based plastics in all products by 2030.
Around 90% of all plastic is made from virgin fossil fuels, according to lobby group PlasticsEurope.
