Glass can only be recycled so many times and then it is worthless as you say. Value depends on the quality, color, and clarity of the glass. Given that cullet is necessary to make new glass, there is always a market for it. Best of all though, bottles can be cleaned and reused many times for a fraction of the energy cost of making new ones.

There are a lot of subtleties to recycling, some in favor generally, environmentally, and economically... some not.
