    Glass. Meh just heated sand.

    Wish it was that simple, but glass & construction-grade silica sand are actually becoming somewhat scarce and facing shortages. The composition, purity, and grain size make some sand vastly more desirable than other sand. There's already commercial operations grinding down quartz slabs, because thats easier than trying to sieve and process out all the non-quartz grains.

    And sand-dredging operations arent any less damaging to the enviroment than other strip mining methods even where there are good deposits. Glass recycling is good.

      Ok thanks did not know that. But let's compare this against a better approach.

      Energy use for recycling

      Vs reuse

      Standardized bottle and jar sizes with pant ( not sure about en word, you pay a bit extra and get it back when returned) that instead of being melted down get a cleaned and reused.

      Sweden had a good system that's still works but not as good as it use to ( some types was removed and different sizes in use) but still have it for 33 cl bottles, as an example.
