The only environmental selling point of glass is that it is recyclable. (Glass production is the most carbon-intensive of any beverage container.) But many cities have stopped accepting glass for recycling. 

The main reason glass recycling is being halted is that it can be dangerous and difficult to sort from other recycled materials. The fragility of glass is the main problem. Sharp broken pieces make it dangerous for workers to collect and sort while tiny shards can be difficult to separate from other large recyclable items. These two factors are the main reasons why many cities have stopped glass recycling altogether.
