Raw materials of glass manufacturing
WebWhen manufacturing soda lime glass, crushed, recycled glass, or cullet, is an additional key ingredient. The amount of cullet used in the batch of glass varies. Cullet melts at a lower temperature which reduces energy consumption and requires fewer raw materials. Borosilicate glass should not be recycled because it is heat-resistant glass.

WebIn a very simplified way, glass-making is a melting and fusion process of raw materials typically consisting of: sand, soda ash (sodium carbonate), dolomite, limestone and salt cake (sodium sulfate). The raw materials are mixed in a batch process, then fed together with waste glass into a furnace where it is heated to approximately 1350 °C.
WebThe materials are mixed with recycled glass, called “cullet.” Cullet is the main ingredient in O-I’s glass bottles and containers. Globally, our glass containers contain an average of 38% recycled glass; we’ve manufactured glass bottles with as much as 90% recycled glass in Europe.
