60% post-consumer fiber

Picked up at a local Starbucks... a paper sleeve wrapped around a take-out cup of Starbucks basic no frills (or thrills) coffee... what caught my attention is the trouble Starbucks went to in leaving me a message on their sleeve:

"This sleeve is made from 60% post-consumer fiber."

I've been thinking about this for about a week... what else is there to think about since HerthaBSC dropped out of the Bundesliga... why only 60?%

What about the other 40%? ... from Dunkin Donuts post-consumers? And if so, does Starbuck hire folks to sift through trash cans looking for thrown away "fiber" from other take out chains? Is that something taught today in US colleges and Universities? Honing your  trash-picking skills to prepare yourself for a career at Starbucks?

And, just what is "post-consumer fiber?" Where does Starbucks draw the line?

Hopefully, it is not something that is a "post-result" of yesterday's morning bran flakes...

Ah, je ... it will be a very long year in Berlin before Hertha gets back on track and out of the Minors.

At least, there is a very new large park that now is open by my house... the one that used to be an American AF Base. So, on sunny Summer mornings, I'm prepared to walk the abandoned runways, sack in hand, looking to collect "post consumer fiber."  

It is re-assuring to know that at my age I can still find career challenges.
