Energy is not the only metric. We need metrics to roughly quantify ecological destruction due to mining, and account for those in our calculations.
- xyzzyz 3y agoMining sand for glass is really negligible environmental destruction. Extra energy needed for recycling vs fresh glass has worse environmental impact.
- khrbrt 3y agoMining sand has terrible effects on riverine ecosystems. You can't just use the sand at the beach.
- Dylan16807 3y agoFor bottle purposes, why can't you use basically any sand? Assume the bottles don't have to be super clear.
