Unless the glass is directly recycled (collected, washed and refilled with the same product) they are much more energy intensive than plastic or aluminium to produce.
- femto 7y agoThe numbers I've seen say that glass uses less energy than plastic. 100% recycled aluminum beats glass, but a more realistic mix, or virgin aluminum, uses more energy than glass. https://www.lowtechmagazine.com/what-is-the-embodied-energy-of-materials.html https://www.lowtechmagazine.com/what-is-the-embodied-energy-...
