Are you grateful that Primark has recycled PLASTIC and added it into their clothing?
With this break through, maybe UK folks will finally stop banging on about the dangers of plastic as it's being recycled into good use!

Not all plastic can be recycled
It still comes from oil

@pdockal A great deal of it is not.
Unfortunately everyone publicly concentrates only on the wanted result, not the means to that end, nor the unintended consequences.
As we've seen with the paranoia about Diesel engines and now with this so-called E10 / E5 petrol.
The diesel problem (exhaust nitrous oxides and particulates) has been pretty well solved as well as it can be, by modern systems and additives.
The new petrol is revealing itself no better than the "old" because its calorific value is lower - hence lower mpg, with a fuel that was also, always inherently and significantly less efficient than diesel. It is also harmful to some engine materials.
.
I believe much of this stems from most of the politicians making the environmental policies and using fancy waffle-words like "technology", knowing very little basic Science and Engineering. They are not pressed on this because most journalists are just as bad. I doubt most of both sets know a Joule from a Watt, iron from steel, the full significance of petroleum or the engineering definition of efficiency - but they damn' well should.
