RE: [GreenYes] glass recovery from commingled curbside program
I think that this opens up the entire issue of why we are recycling --
saving of landfill space, environmental benefits, economic development, etc,
and the relative merits of each goal to our final decision making. 

My sense is that recycling glass has some of the lower environmental
benefits in terms of energy saved, reduction in leachate and gas generation
at landfills, saving scarce natural resources, reducing toxic emissions
during product manufacture, etc.

The next question I would have is how to value the various benefits and then
relate them to the costs of recycling. There is a field of economics that
attempts to do this (environmental valuation), and some European countries
that have used this approach to impact decisions, but I am not sure that it
has developed yet to the point where a significant number of people in the
US would feel comfortable with it.

I would like to hear what others think about these issues.
