Making glass from scratch is incredibly energy intensive, and glass impurities can be handled (purified), so it always makes sense to recycle glass. Don't let your officials tell you any different.

I heard on a recent podcast from a Dutch recycler that recycling glas only saves ~10% of energy creating new glass. Melting the glass requires heat, and the raw material is not much more expensive than collecting used glass.

You're not filling a landfill and you're not gathering more raw material. Both seem like a win, especially if it's cheaper, even by just a little.

Not much more than melting existing glass. It's not like aluminum, where melting is much cheaper than refining in the first place.

It's much easier to handle impurities when you start with clean sand.

Not in single stream recycling. The problem? Glass gets crushed and ruins other recyclable materials.
Also glass is very heavy when compared to a similar strength container made of plastic. That is why plastic took over the market.
As for recycling glass into other glass, I can't say.
