Lego is the manufacturer of everyone's favored plastic blocks that interlock creating buildings, gears and mini-figures. The first, early version of the blocks was created in 1949 in Billund, Denmark. Since then the company has produced over 600 billion Lego pieces. Lego's mission is to inspire and foster the creativity of the builders of tomorrow. Through product licensing with Disney, Minecraft, Harry Poter or Marvel, it is reaching a very broad spectrum of audiences. Even though children have always been the main focus of the company there is a growing community of adults who collect Lego sets as a hobby. Some of the rare sets, like 5000+ pieces Millennium Falcon, cost tenfold the price when they aren't any more available in the regular retail. In 2018 Lego started researching possibilities to create plastic pieces more sustainably. The company introduced a new material -polyethylene made from sugar cane. For now, only 2% of elements are produced from this plant-based plastic, but Lego promises to use only sustainable materials by 2030. Also, the packaging of the sets should get more eco-friendly in the coming years. To be more environmentally conscious with your Lego bricks, make sure you donate them to kids in need to play when you're no longer interested in building yourself.
