The production of glass bottles is one of the more energy-consuming packaging commodities, and it is very valuable to recover and use. How to recycle glass packaging more reasonably is a hot topic for domestic and foreign research.

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 the recycling of glass bottles requires less heat, and the furnace body wear can also be reduced。

The specific process is to pre-process the recovered glass bottles, such as starting sorting, cleaning, and sorting by color.

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 glass bottle factories use 20% cullet in the process of manufacturing glass bottles to promote melting and optimal mixing with raw materials such as quartz sand, feldspar and alkali.

Of course, the content of broken glass will affect the production cost, material color and price of the glass bottle.
