Great news! A while back LEGO made plans to start making their famous bricks from plants which is a mixed bag; its sugar cane and it only works with softer parts like tree branches, leaves, etc. No success in making the core pieces such as their trademarked 2×4 brick. Better than ethanol but it was a start.
This plan to repurpose used plastic (probably bottles mainly) is much, much better. The short version if you don’t want to click on the link; they can make on average 10 2×4 bricks from a one-liter bottle with the proper amount of clutch power to be LEGO. So in the US, we prefer the two-liter bottle so 20 standard bricks would be awesome.
I’m hoping those innovative Danes get cracking on this and deploy these recycled pieces ASAP. Then the next order of business, the West and China should give LEGO a contract or dibs on the disgusting plastic continent between California and Hawaii. Anything created from it should be a limited series like their exclusives for Friends or Big Bang Theory. Just don’t make it a recreation of what it used to be.
