Glass bottles can avoid the 'trash' stream with 'bottle bill' legislation. Most of europe does this, some even for PET and aluminium cans. Collection is essentially the same route as delivery to the cusomers, but in reverse: the customer brings it back to the shop. The bottling plants eventually bring in their output. It's more economically all around than re-flowing the glass bottles. I know that Belgian brewers lean heavily on reused green and brown bottles. In this case, it helps that there are a few near-universal beer bottle types, but perhaps that's more a result of the reuse. Some music festivals use '10 empty plastic cups = 1 free drink' to reduce the amount of single-use plastic trash laying around. It's simple economics.
