For glass it only ever made sense to reuse it, like cleaning and filling bottles. Otherwise, glass is so cheap and easy to make that recycling makes no sense. It takes just as much energy to melt old glass for recycling as it is to melt sand down for new glass, and the sand is going to come in cleaner and with less contaminates than used glass.
- v_lisivka 8y agoIt's not true. Melting of crystals needs about 1/3 more energy and time, and higher temperature, than softening of recycled glass. http://www.climatetechwiki.org/technology/glass http://www.climatetechwiki.org/technology/glass
