Figure 1 shows a process flow chart for manufacturing glass. Raw materials are mixed, melted, formed and heat treated to make the finished product. Scrap glass from throughout the process, called cullet, is returned to the glass melting furnace. Returning the cullet reduces waste and saves energy in the glassmaking process.

2021年8月25日 Glass manufacturing is a moderately EI industry [5, 13, 15, 16] 1. Certainly, British Glass – a representative trade association of more than 70 constituent organisations that provides a voice for the sector – regards glass melting as a particularly EI process in which the furnace accounts for around 75% of energy consumption [18].

Glass manufacture also is a heavily energy intensive industry. This includes the production of container glass (bottles), sheet or plate glass (via the float process), fiberglass, specialty glass, and secondary products made from glass. Data from Europe show that there has been a dramatic improvement in energy efficiency.
