People around the world know LEGOs very well. These years, the LEGO Group are trying using recycled plastic (可回收塑料) to make LEGO bricks. They aren’t ready yet, but the company says it’s making big progress.
In fact, people who often play LEGOs may know that the first LEGO brick came out in 1949. Since about 1960, LEGO bricks have been made from a kind of plastic called ABS. Sadly, it can’t really be recycled, and it takes a long time to break down.
But since 2015, LEGO has been trying to make their products (产品) more environment-friendly. Three years ago, the company began making some LEGO parts with a kind of plastic made from sugar cane (甘蔗). Recently, LEGO decided to use paper bags only. And the company has also started to make bricks by using recycled plastic.
Over the past three years, the company has tested over 250 different ways of creating LEGO bricks from recycled plastic. Now, the company has found a way to make a good 2×4 brick from PET plastic, which is softer than ABS plastic and can be found in things like bottles and clothing. The only problem is that the company should think about how to make PET plastic stronger and give it better clutch power (离合力) like ABS.
The company believes that they can find more sustainable materials (可持续材料) to make all of their main products by the year 2030. Making bricks from used PET instead of new ABS cannot only cut plastic waste, but also cut pollution by about 70%.
