No, I don‘t think it is.
Not everything that isn‘t working perfectly is automatically a scam. There are many factors that might prevent a relatively large amount of trash from being recycled, like, for example, contamination with other substances or additives, unseparated composite materials or simply technical limitations.
That‘s not a scam, though, that‘s just the current state of the available technology.
Here in Germany, it‘s pretty common knowledge that these limitations exist. Recycling is still very common, as ~40% is still far better than 0%.
Sorry that I can’t really take your argument seriously, but which recycling advert claims to recycle every bit of plastic ever produced on earth? That’s what those 9% are.
I’m sure there are misleading ads in the recycling industry. Those are practically everywhere. But I’d really like to see that one.
The percentages which are probably actually used in promotional material, because they actually have something to do with what your local recycling plant is responsible for, and not what has been polluting the environment since the early nineteen-hundreds, can be seen in the table for Regional Data, which I’ve previously linked to.
If you still want to stick to the claim that because only 9% of every bit of plastic ever produced by all of humankind (1% more than once) makes plastic recycling in general a scam, I’ll be genuinely envious of your ability to reach mind-twisting conclusions from data which has absolutely nothing to do with the actual argument and your persistence in keeping that opinion. Maybe you can teach me sometime.
