What the meanings of the glass recycle?
Most of the general glass products are made by silicon (Si). Due to the high melting point, which can afford high temperature (1,723℃), refining the glass products is very difficult, and also needs lots of energy. The power saved form recycling one glass could light a light bulb (100 candlepower) about 4 hours. It also could reduce the problems of 50% water pollution and 20% air pollution. In short, the significance is extraordinary for people on glass recycle.
