Interesting my municipality recycles glass, but like, why? Silica is the most common mineral in the crust, easily accessible almost everywhere, and recycling it takes as much energy if not more than just making new. It's not like aluminum or steel where there are significant energy savings to recycling vs mining and refining.
It saves 30% of the energy inputs to reuse slightly contaminated glass, especially when done locally.
That's ignoring the energy inputs of mining and delivering the silica.

It's just melted, mixed and reused, AFAIK. We're recycling glass since forever (maybe mid 90s), and the recycling bins were put out by our national glassware company.
They even have a special line built with these, recycled glasses, which I don't remember the name. They also have a "upcycle" line where they repurpose their fine but not perfect items to other things. Both are excellent lines and are not more expensive than their usual wares.
Far, far earlier than the '90s. Glass has been regularly recycled from the early days of glassmaking itself. It's crushed up into "cullet" and mixed back in.
Glass is great for this because it doesn't degrade from being remelted and reformed, and using cullet reduces the cost of energy and new raw materials when making new glass.
You’re absolutely right. I meant recycling as ordinary citizens in my country with that date.
