Hi again, @shaka.
Yeah, I get what you mean. I sometimes find my biodegradeable waste bags to have been torn while still in the bin. It's really frustrating when I have to clean the bin to remove old food..
It unfortunately seems like we have to choose a trade-off for most "green" products these days; either we get it cheap and durable, or we get it from a sustainable source. It would be truly amazing if we managed to create a type of bioplastic that was just as good, or even better, than regular fossil fuel plastic.
This is a great addition to your post. In theory, if the polymer would exactly be the same then so should be the quality of the bricks. However, in chemistry, a different manufacturing process always means a different product, e.g. in terms of impurities. Now, in particular when it comes to polymerization, small amounts in whatever remnants can have a measurable impact on the products quality.
That's a good point. There's always a gap between theory and real life, so I guess it all boild down to whether or not we have good faith in the company that attempts this. While I want to trust that Lego is certain about this, I also think you are right in questioning them. Maybe this is also the reason why they are only going to be making 1 - 2 % of the new bricks from this green plastic; to kind of test them in real situations before increasing the production? I'm sure they have tested it a lot in the labs, but there can also be a gap between the lab and real life as well.
That was a wonderful conversation @shaka and @valth. The questions that I had in my mind after reading the article were discussed clearly in this conversation. Thank you.
I'm glad you got your questions answered :) I guess I should probably have added a bit about this in the main post!
