There was a nicely done energy analysis on glass containers and
recycling a few years back, I believe by Argonne National Labs.

It had some interesting conclusions in it on the energy consumption
of transportation back to the manufacturers vs the energy saved by
using cullet.

If you'd like, I can try to find the exact citation; perhaps it's
even on the web, although I had read the paper copy.

In our curbside collection program, there is a very high glass
breakage rate, but the broken glass is run through optical sorters
to upgrade the material. However, the economics of glass recycling
back into containers is very poor; the economic value of glass
for most alternative uses is also minimal.

If people are interested, I would be glad to send them the lastest
electronic version of the listing of a database on alternative
uses. It's about 110 pages long and lists just under 300 projects
for reuse and recycling glass for non-container uses.
