Application of Broken Glass in Glass Bottle Production

In the production of glass bottles, recycled broken glass can be used. The recycling of glass bottles used as raw materials refers to the use of unusable glass bottle packaging waste as additional raw materials for the manufacture of glass bottle products.

In the production of glass bottles, recycled cullet can be used, and the recycling of glass bottles for raw materials refers to the use of unusable glass bottle packaging waste as additional raw materials for the manufacture of glass bottle products. The glass products here are not only glass packaging bottles, but also product wastes such as other building materials and daily-use glass products. Adding an appropriate amount of cullet to the raw materials is helpful to the manufacture of glass, because cullet can be melted at a lower humidity than other raw materials. Because recycling glass bottles requires less heat, and the furnace body wear can also be reduced. Studies have shown that in the manufacture of glass bottles, mixing about 30% of cullet is the most appropriate, so it can also increase the utilization rate of recycled glass and enhance environmental protection.

At present, most of the glass bottle manufacturing process uses 20% cullet to promote melting and optimal mixing with raw materials such as quartz sand, feldspar and alkali.
