RE: [GreenYes] glass recovery from commingled curbside program
There is a strong emphasis in this thread being placed simply on collection
methods and costs. That is as incomplete a view of recycling as is
suggesting the price per ton at a landfill is the cost of disposal.

There are problems with the collection of glass that can be mitigated
through the collection system/methods and technological solutions at the
back-end. But given Bob's cogent analysis of the benefits of recycling
glass, I'd be interested to hear if there is compelling reason NOT to
collect glass at the curbside. If there are, are these reasons that are
specific to the material or the collection system?

Besides the benefits of glass-to-glass and glass as ceramic that Bob laid
out, there are also real benefits to using glass as an aggregate additive in
roadbase. In rock-poor areas, it can save on raw material costs by up to $10
a ton, it reduces the mining of aggregate and it has structural benefits in
terms of how the aggregate "lays down" with the grader.

Are you folks familiar with the expression 'highest and best use?" Glass is
more than heavy - it is a highly recyclable packaging material. For all of
the sermons I've read on this list about dealing with these issues on the
front end - in the design of the product...we have now come to the
conclusion that glass has less value than plastic (a very difficult material
to recycle) so let's just dump it.

What is it we are are being asked to do or believe?

zero waste from design or the easiest things to recycle and everything else
goes in the trash?

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.
