Polypropylene is right.  And it should be enviromentally safer than PVC.  
And the search I did didn't turn up U.S. sources on the first page--China, 
India, Israel, yes.

This might tell those of us who have never heard of it a bit more.  (.is is 
Israel, isn't it?)

"PP Sewer pipes made by SET are mostly used for inside sewer systems. The 
pipes are produced with nominal diameter 40, 50, 75 og 110 mm and in the 
lengths of 150, 250, 500, 1000 og 2000 mm. PP pipes have more heat and 
chemical resistance than PVC pipes and also fullfill demands of durable 
flame resistance. Pipes and joints have puch-fit sockets at the end and 
prefixed sealing as the PVC pipes. SET Pipe factory is also selling 
nessesary joints and fittings for the PP pipes.

Here in Denmark it is possible to buy something called "PP"-pipes instead
of PVC. While pex (as far as I know) is bendable and of smaller
dimensions, the PP-pipes are similar to the PVC-pipes.

I'm afraid I can't rememer what PP stands for - perhaps poly-prophylene or
something like that? It's a kind of plastic, but much less of an
environmental hazard than PVC.

I expected someone else (who could tell you the actual name of the stuff)
to mention it, but it doesn't look like anyone else knows of it. Here it
is quite common. Hasn't it gotten so far as the US, or wherever else
people are writing from?
