With all the glass being thrown away for some reason the concrete industry came to my mind. Made me wonder if crushed glass could be used in concrete since glass is essential sand? I know concrete needs a specific type or sand and maybe glass would be a no go for cement but it popped in my mind and has me wondering what we could replace the sand with. Also the main issue I see with glass is it is at least twice as heavy. So the carbon emissions savings would need to offset the transportation emissions.

It appears adding glass to concrete increases durability, while adding plastic or rubber decreases durability (sidenote: adding rubber to asphalt increases durability of tarmac/road surfaces, while reducing maintenance costs and road noise). https://www.sciencedirect.com/science/article/abs/pii/S0950061820332463 https://www.sciencedirect.com/science/article/abs/pii/S09500... http://asphaltmagazine.com/asphalt-rubber-pavement-moves-east-and-north/ http://asphaltmagazine.com/asphalt-rubber-pavement-moves-eas...
