| Since some months or a year ago I have been noticing that some parts feel the
same, newer ones have a matte finish (or not shiny?) and weight less.
For example:
Left matte weights 0.57g
Right shiny weights 0.64g
So be careful if you weight them to count... the difference could be big.
PD: Someone posted in the forum some time ago a huge difference in weight between
two 100u bags of the same part, but couldn't find it to reply now.

But isn't this something that has been happening for years? Or has it become
a bigger issue in the last few months?

Well, I have been handling huge amounts of parts in since 2015 and I noticed
it more lately.

| | This might have to do with the plant-based plastic Lego is starting to use. |

That needs to confirmed. If true, then it could be grounds for a major catalog
revamp, because some buyers are trying to recreate older sets, and they do not
want new plastic parts intermingled. There would need to be some way to distinguish
which is which. Any chemists lurking about ?

Not a chemist but:
First, to be pedantic, all plastics are plant-based: they come from petrol which
comes from plants.
The “plant-based plastic” is actually “sustainable plastic” (not made from petrol
derivatives but from sugar cane alcohol).
For now (that is, no contradictory announcement was made), the sustainable plastic
LEGO uses is PE (soft parts), not ABS (bricks…).
And there’s no difference between petrol-PE and sugar cane-PE.
So that’s not the fault of the so-called “plant-based plastic.”
That being said, LEGO also continously tunes its plastics. In more or less
big steps, like using pre-coloured pellets or not or just “tinkerings.”
Lastly, the biggest change has been to go from PC to MABS for transparent parts
(that leads to cloudy parts when it’s not Trans-Clear).
Last year, the chief of LEGO’s Quality Perception dpt said they tried very very
hard to make the appearance & feel constistent. But he also said one of the
changes made snapping go more “ploom” than “click” (paraphrasing, with my faulty
memory and French accent  ).
