Lego wants to solve the world’s plastics problem with a biomaterial that can survive generations of play

Wind turbines made of Lego bricks.

In March, the Lego Group revealed the world’s highest Lego wind turbine to commemorate having actually fulfilled its 100%renewable-energy target 3 years ahead of schedule.The 30-ft-tall wind turbine constructed from 146,000 Lego bricks pays tribute to the Burbo Bank Extension offshore wind farm near Liverpool, UK, one of Lego’s investments in wind energy amounting to$940 million given that 2012. Companies frequently satisfy( and even beat)enthusiastic renewable resource targets by buying clean electrical power– such as wind power– to balance out conventional electricity intake. As soon as Burbo Bank began producing electrical power in May, the total output of clean energy from Lego’s investments sufficed to balance out the power used by the business’s factories, offices, and stores worldwide.Many big brands have actually set renewable-energy targets to help minimize their co2 footprints, however a recently released research study concludes offsetting carbon emissions by purchasing renewable resource isn’t sufficient to save the world. We’ll likewise require to actually reduce carbon emissions. In 2015, Lego set another target: changing 20 types of standard plastics utilized in making its bricks with sustainable materials by 2030 to help curb the company’s total carbon dioxide emissions.The Denmark-based toy maker invested $155 million into a Sustainable Products, where materials

specialists are exploring alternatives to plastics made from fossil fuels. Lego attributes simply 10%of the carbon dioxide emitted during the lifecycle of Lego bricks to the company’s own factories, workplaces, and stores. The other 90%originates from sources outside its direct control, such as item transport andcirculation– and from the making of the tiny plastic pieces it sources from materials providers to develop its bricks.In reality, about 4%of the annual usage of petroleum worldwide is utilized to make plastic, and another 4%is utilized to power plastics-manufacturing processes, according to a 2015 study by the Worldwatch Institute, a Washington, DC-based ecological research group.One service is, which are originated from plants in the eyes of their consumers.Conventional plastics have been traditionally more affordable, however the cost of bioplastics has come down enough to draw some big brand names. Coca-Cola, for example, has actually dispersed 35 billion plant-based bottles in 40 nations, getting rid of an estimated 315,000 metric lots of carbon dioxide emissions. The beverage company’s ultimate goal is to discover a 100%sustainable, responsibly sourced product for its bottles that is fully recyclable.Lego wants the same from any sustainable alternative to the 20 traditional plastics now used in their items. Substitute materials also should be as durable as existing plastics utilized, such as the incredibly difficult, oil-based ABS(acrylonitrile-butadiene-styrene), and as completely interlocking and in reverse compatible as every Lego brick made given that 1958. Tim Brooks, vice president of environmental duty for the Lego Group, oversees the work of the Sustainable Materials Center’s 70 specialists whose challenging task includes meeting the business’s exacting requirements for

product safety, quality, and durability. Every prospective bioplastic is checked for strength, stiffness, dimensional stability, and impact strength– determined by whether an aspect might break or splinter throughout play .”I will hand down the Lego bricks I played with as a kid and the bricks my dad gave to me to my kid, “says Brooks.” We understand Lego bricks are often passed down through generations– making it so important that the sustainable products chosen for our products be extremely resilient.” Every Lego element demands something various from a sustainable material. Bricks require difficult materials like ABS; axles and equipment wheels require strong materials with low friction; little adapters need strong material that is also stiff; and tires need to be soft.”

We want any bio-based product to be efficient in being specifically formed, or to mold to simply a couple of microns,”states Brooks,”and we desire it to be glossy.” Brooks indicated a side-by-side contrast of two green Lego bricks: one a sample made from wheat sugar and the other a conventional plastic. The test brick’s color was dull and flat compared with the glossy, bright-green traditional brick. A bioplastics test brick(left)next to a traditional plastic brick(right).

In spite of the difficulties, Brooks is positive the company will determine bio-based products

it can make work for their products– and knows it’s something Lego has to do to be successful in the age of climate change. Brooks states,”We understand that making bricks has an influence on the world, and we want it to be a favorable one. “Lackner says Lego’s commitment is substantial. If more large business would devote to sourcing sustainable

plastics, it could substantially limit the comprehensive environmental damage that originates from burning fossil fuels to produce 300 million lots of plastics around the world every year.”The huge gamers can alter the game,”says Lackner.
