I know our local waste department has had a very hard time finding anyone to recycle the glass they collect. Some of it ends up crushed and tumbled to be used for landscaping. But most of it is crushed and layered over the landfill liner. That is technically recycling/reuse as I think something else like gravel would be used otherwise, but it isn't what people expect when they recycle their bottles. I don't have any official information about what prevents it from being recycled but I've heard word of mouth that transportation costs are a huge factor if you don't already have glass production in your area. Also that sorting is a big issue, as different glasses have different additives, and need to be recycled separately but sorting is hard to do safely and cost effectively.
