Effectively addressing global warming demands a substantial reduction in CO₂ emissions, presenting major challenges, particularly for energy-intensive processes and manufacturing industries, which account for roughly one-third of global energy consumption. A key solution lies in the smart electrification of operational processes across these sectors. Electrification offers significant decarbonization potential. In this context, a glass production plant involved in the European Project CITADEL, granted by the European Health and Digital Executive Agency (grant agreement No. 101138794), is examined. Such a process is indeed critical due to its high energy demand: 75–85% of the total energy is spent on heating raw materials or waste glass in the glass melting furnace to more than 1500 °C, a process that runs continuously throughout its entire lifetime (approximately 8–10 years). These emissions include not only CO₂ from fuel combustion but also NOₓ and other pollutants that contribute to air quality degradation. As a result, decarbonizing the heating phase is essential for reducing the overall environmental footprint of glass manufacturing. To address this gap, the present work develops a Life Cycle Assessment of the glass bottle production process, comparing the environmental performance of a conventional system heated using gas burners with that of an alternative process employing electric resistance heating. The results, obtained by employing data from a pilot plant, provide valuable insights into the key variables that most significantly affect the environmental performance of the process, as well as the potential benefits that can be achieved through the adoption of electric heating.
