I critique that their source does not actually say what they claim it says: Nowhere in there is a 95% number, it doesn't give any percentage at all about how much can be recycled.

All it states is that "it can be recycled" and how "90% of its potential energy still remains", which is about as useful as declaring the plastic problem as solved because "plastic can be recycled".

That makes the 95% number an assertion without evidence, as such, it can be dismissed without evidence.
