RE: [GreenYes] glass recovery from commingled curbside program

Does it really make sense not to collect it curbside?  We have 10,000 tons of glass each year from our residential program.  Imagine the impact of individuals taking their miniscule loads to drop-off centers.

I have heard over the years numerous discussions on various commodities and how we wonder whether or not we ought to collect them, especially when the markets are in a downturn.  I have always believed, and this is particularly true for larger municipal programs (but it could work with joint efforts with smaller communities), that the collection stream ought to be broad/diversified, much like you would consider for an investment portfolio. Markets go up and down--that is a given.  You can soften the impact of market volatility by diversifying the type of materials you collect.  And though I am not one to rely on technology to solve our problems, I think contamination and quality issues can be addressed, at least to some degree, by carefully considering the collection and processing methods utilized for the mixed stream of materials.  This is not to say that you should collect something because it is there, but you ought to do some serious analysis (as Mr. Reindl suggests in his response on this topic) on the collection, processing, and marketability of the materials and weigh that against the environmental benefits.

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.
