What they'd want to do is try to recover and reuse heat. In principle, there's no reason "new" heat has to be added each time they heat a batch of glass, if heat can be transferred from cooling glass back to the input materials.
Have you worked in any industrial or craft setting involving molten glass or metal? Walked around a workshop? There's no way the heat is going back into the process.
This is one of few places where I’d like to sprinkle a little more government overreach in just the right way - to prevent manufacturers from walling clearly essential behaviour behind an app. That’s far too gray of a line for governments to handle, but I can dream.
This made me laugh. In college in the late 80's I repaired a roommate's not-quite vintage C64 fastloader cartridge with a bad wire bodge using a lighter and the tine of a dining hall fork...
My experience working with glass is that you _don't_ want it cooled quickly. It will shatter or get internal stresses that cause it to shatter later. You anneal it in a slowly cooling oven over time. Some steels and brass can be annealed slowly and that heat could, I suppose, be captured. Tempering probably not.
> Still, even somewhat lower grade heat can be upgraded back to high grade heat with high temperature heat pumps.
Which requires energy and incurs losses. If you have energy, assuming electricity, that's cheap enough to scavenge low-level waste heat you probably don't need to recapture the heat.
