Well yeah, there's the problem that glass is trivially easy to manufacture from sand, and the amount of labor and energy use to remove and process these screens is greater than the savings, especially since most glass these days that is sent for recycling is thrown into giant mountains of unwanted glass that is never used by anyone. Also, if you have to use a bunch of highly toxic solvents that are dangerous to work with so people can by hand remove the glue before even getting to that point, one may reasonably ask what exactly about this process is green.

That isn't generally true, mostly because it is valuable as long as you have glass production nearby. The UK does have a mountain of green glass as it drinks loads of wine but doesn't produce much. But this is apparently quite unusual, at least according to the Economist. - http://www.economist.com/node/9249262 http://www.economist.com/node/9249262
