Glass Industry

The glass industry is highly energy-intensive, requiring extreme heat to melt raw materials like sand, soda ash, and limestone. Energy use is dominated by high-temperature furnaces, making decarbonization a major challenge for this sector.

Energy Use & Sources
Most glass production relies on fossil fuels—particularly natural gas—for continuous, high-temperature operations. This results in significant CO₂ emissions from both fuel combustion and raw material reactions.

Efficiency & Electrification
Energy efficiency measures like improved furnace insulation and heat recovery systems are being adopted. Electric melting and hybrid furnaces offer cleaner alternatives, especially when powered by renewables.

Future Outlook
Decarbonizing glass production will require a shift to low-carbon energy, increased recycling (cullet use), and innovations in furnace design. Hydrogen and bioenergy may also support greener glass manufacturing.
