Lego Drops Plans To Make Bricks From Recycled Plastic Bottles (cbsnews.com) 58
An anonymous reader quotes a report from CBS News: Denmark's Lego said on Monday that it remains committed to its quest to find sustainable materials to reduce carbon emissions, even after an experiment by the world's largest toymaker to use recycled bottles did not work. Lego said it has "decided not to progress" with making its trademark colorful bricks from recycled plastic bottles made of polyethylene terephthalate, known as PET, and after more than two years of testing "found the material didn't reduce carbon emissions." Lego enthusiastically announced in 2021 that the prototype PET blocks had become the first recycled alternative to pass its "strict" quality, safety and play requirements, following experimentation with several other iterations that proved not durable enough.
The company said scientists and engineers tested more than 250 variations of PET materials, as well as hundreds of other plastic formulations, before nailing down the prototype, which was made with plastic sourced from suppliers in the U.S. that were approved by the Food and Drug Administration and European Food Safety Authority. On average, a one-liter plastic PET bottle made enough raw material for ten 2 x 4 Lego bricks. Despite the determination that the PET prototype failed to save on carbon emissions, Lego said it remained "fully committed to making Lego bricks from sustainable materials by 2032." [...] Lego said it will continue to use bio-polypropylene, the sustainable and biological variant of polyethylene -- a plastic used in everything from consumer and food packaging to tires -- for parts in Lego sets such as leaves, trees and other accessories.

If you dissolve the lignin out such that you are left with a pure cellulose pulp, which is what you do for paper manufacturing, you can dissolve the cellulose in an appropriate solvent and injection mold it to your heart's content. This is how we make cellophane. The most common solvents used are horribly toxic and environmentally destructive, however. There have been efforts to make this process more green. I don't know how successful they've been to this point.

You specifically mentioned toxicity in your reply, rather than saying "it won't dissolve" so I'm sure you can understand the confusion.
By the way, since you're the expert: would you actually use cellophane in this application? As far as I know, it's a thin film and not something suitable for an application like lego bricks. hence my assumption that it would be some other kind of cellulose based material--of which I have seen many fall apart when exposed to moisture.

Cellophane is just a particular product name that people are familiar with. Because it's just cellulose. Cellophane, rayon, "transparent wood", and the like are all just different applications of cellulose that have been dissolved into viscose and then made into various shapes.
The same way rayon doesn't dissolve in rain, the bricks wouldn't dissolve if a child put them in their mouth. As it's just cellulose, it is non-toxic. Though the production of viscose requires toxic chemicals, those are not present i

Turns out that wood, by its own nature, is a carbon capture device. As you cut trees to harvest wood, you replant new ones. Every chunk of wood you ship is encapsulating carbon, and it is replenished by the reforesting backfill. So, why not wood?
I suspect you know why not and are simply trolling. How long will a wooden lego last being chewed on by a 2 year old? Jeebus Christo.

They also sell 8l bottles here, but I find them too unwieldy; and reusable 20l bottles which are used in conjunction with a dispensing machine.

I recall my chemistry professor at university starting a lecture with a bit of an aside on how we'd be better off burning plastic for fuel than trying to recycle it. I believe he wanted to point this out because at the time there was some debate about a waste-to-electricity power plant being planned nearby. Perhaps less petroleum is used since, as that chemistry professor pointed out, we aren't hauling plastic all over the place for recycling and burning petroleum fuel to do it.
