 >>Care to elaborate? Do you have a timetable in mind when you say 'soon'?

Soon as in as soon as as soon as we ensure that politics stop getting in 
the way.  All politics,  all agendas need to be set aside and it needs 
to be focused upon.  then it will be solved.  This won't be easy as the 
big Oil coal companies will fight it tooth and nail.

 >>So, what does the aluminum recycling industry make out of ground up 
soft drink cans?

Doing my part here i haven't drank soda in years.

 >>Do you imagine that the rubber that wears off the water bureau's 
truck's tires is collected, scraped off the asphalt, and somehow allowed 
to reenter the tire-making process?

You have me there.  and I see no way at this time to replace that rubber 
with a more sustainable alternative,  but I'm no expert in the field.  I 
wouldn't call me an expert an the 'Green' area of knowledge either,  
that's why i read the lists and from time to time ask questions.  like I 
did this time.

When I asked "Are there non sustainable materials used in 
purification?"  I was actually referring to the actual purification 
processing not the infrastructure that is in most cases already in 
place, and lasts for a long time.
