They make plastic though. Surely they recycle the scrap
Lego bricks are made using virgin plastic, which I assume means all scrap is not recycled and used to make more Lego.
Some parts, like flexible parts and transparent parts are made using more sustainable materials, whether that consists of some recycled material or plant derived plastics.
When trying to find differences between virgin and recycled scap plastic all I get is AI crap product comparison sites and various companies trying to sell their recycling system...
What downsides is there to recycling your own plastic scrap, which you have had full control over the entire time. I would imagine trying to color match with consumer waste plastic is a nightmare, same with moisture (at least that's an issue when printing). But if you have a bunch of plastic in an homogeneous color and you grind it up to make something of the same color, and you've had the scraps in a controlled environment, then what more issues are there?
The plastic will be grounded up and re-used, that's 100%, but it still requires quite a bit of virgin pellets to be mixed in. Here's why:
This, unfortunately much of what is given to a recycling plant is still ultimately thrown out, there are some exceptions, metals for instance
Still takes time to run the recycling systems and therefor money.
Also, think of it this way - you spend $X per 1000 bricks, but you can only sell 10% of those bricks. The remaining bricks get melted down at a cost of $Y. You then spend $9X/10 to produce another 900 bricks, of which only 90 are sellable. Rinse and repeat until all bricks are viable. You'll have spent a hell of a lot of money producing the later batches.
