what about optical sorting?  Or isn't it cost effective...?

The City of L.A. has a commingled program and they claim they get a pretty good recycle rate for the glass, I enough usable material at the end of the process.  Other cities collect everything else commingled except for the glass.  I think it's true that mixing all materials together has lowered the value of glass and made it mostly a contaminant.

A cynic might speculate that the only reason to include glass in curbside is that because of its weight it bumps up recovery rates (as long as recovery is measured as material collected at curbside as opposed to material successfully marketed.

Hi Michele,

You're a brave woman to say this ... and it makes me wonder if its true?
Can anyone out there make a "compelling environmental reason" to collect
curbside glass?   The key statement here is "curbside" as opposed to
recycling glass through drop-off centers.
