"Remelting glass to make more glass is more energy intensive than making new glass."---hdfbdtbcdg
The first source I found on this subject directly contradicts your claim:
"The primary energy consumption totals are 17.0 x 10^6 Btu/ton of bottles with no postconsumer recycling, 14.8
x 10^6 Btu/ton with maximum recycling, and 15.9 x 10^6
Btu/ton for the current mix of recycling. The total primary energy use decreases as the percent of glass recycled rises"

Cool! I seem to have been wrong. I wonder how those numbers compare with reuse? One would have to look at TOC including transport (e.g. transportation of wine bottle back to growing regions).
