The Lego Recycling Machine is a fun, relatable, and fictional story that adults can use to teach children how technology and circular thinking will inspire the earth-friendly product designs of the future.

Last week, I drove twenty-two miles to pour two Home Depot buckets of random Lego blocks into the eager mouth of a Lego Recycling Machine.

The Machine was located at the end of a nondescript stripmall, right next to an In-N-Out burger. The entire storefront was occupied by a huge Lego logo, a collection chute (the mouth), an exit hole (for boxes and envelopes), and a locked service door.

I never saw an employee. The machine was exclusively operated through the Lego Loop app that I downloaded to my phone.

Nine minutes after pouring ten gallons of mixed Legos into the machine, using the Lego Loop app, I paid for an organized box that included: 1,830 blocks from our bucket, 315 Lego Next Life (LNL) blocks, and three new Lego Building Instruction Booklets.

I left 986 [unneeded] blocks in the machine for resale to others as LNL blocks. Every LNL block sold converts to fractional Lego Coin [crypto] that I can use within the rapidly expanding LNL economy.

91 missing blocks were mailed to me from machines located elsewhere, as these machines are each capable of autonomously preparing packages for shipping.

Even more fun, students from my son’s school used the Lego Loop app to form a club. Using the app, members voted on projects by pledging blocks and Lego Coin to an array of designs. The first build completed, a huge Battlestar Cruiser, used 9,002 blocks pledged by eighteen members. Using the pledged Lego Coin, blocks needed to complete four additional designs are being purchased from others.

Lego Recycling has become so popular that billions of abandoned Legos have been sourced from yard sales, flea markets, basements, and attics the world over.

Lego Group, the company that makes the machines, now earns more profit per year from recycling Legos and reselling designs than they do from manufacturing. Moreover, the machines are adept at detecting and rejecting counterfeits; this feature has almost wiped out the Lego black market.

Lego’s Director of Regenerative Initiatives, Hans Swedman, attributes the success of the Lego Recycling Machine and the Lego Loop app to artificial intelligence and machine learning. “The machine is able to sort, size, organize, and assemble boxes of Legos and new Building Instructions in ways that could not be imagined, and at speeds that could not be matched, by an army of engineers!”

The Lego Loop app is not only enabling a new social recycling and construction experience, it’s also fostering a generation of Lego recycling entrepreneurs. One eleven-year old boy, alias Joe Cakes, has reclaimed and is reselling nearly a million blocks; his mother told me that Joe and his father visited several hundred yard sales last year, and that Joe has earned enough LNL crypto to almost pay for his first year of college!

The Lego Recycling Machine has become so important to the Lego Group that the company has been able to cut its use of virgin plastics over the last three years by more than 50%.

Lego Group, a company which has produced over 400,000,000,000 plastic bricks since 1958, is showing the world that circular thinking, machine learning, and blockchain technology can create a profitable, regenerative, niche economy that is far more reliant on preexisting product than new.

Who would have thought that the top selling toy of 2022 would be a bucket of your old blocks and a couple of machine-generated Building Instruction Booklets?

This post was inspired through conversations with my son (age 11) about AI and ML; by the nine years I spent innovating in the Auto Recycling industry; by the Ellen MacArthur Foundation; by The Paperclip Maximizer; and by a post in the Wall Street Journal titled “Lego Struggles to Find a Plant-Based Plastic That Clicks”.

After reading about Lego’s noble effort to engineer plant-based blocks, I thought, with 400Bn Legos on earth, why bother? We don’t need more, we just need a smarter way to recover and recycle the nature-resistant bricks that already exist.
