Technological Energy Efficiency Improvements in Glass-Production Industries and Their Future Perspectives in Italy

The glass industry is highly energy-intensive, consuming approximately 500–700 million GJ each year. Replacing inefficient equipment with better-performing a good strategy to reduce the energy consumption of plant. Since there are many alternative solutions, choice which technological improvement implement usually difficult. Therefore, review solutions in plant pivotal. literature offers similar studies, but they not sufficiently up-to-date and do represent actual state art, should be updated. Thus, this paper aims provide an updated list clustering them into different categories (e.g., process stage). Moreover, investigates current applicability energy-saving Italy. Specifically, sample 103 Italian companies considered type interventions that recently implemented or intend adopt analyzed. Quantitative statistical economic analyses were conducted highlight most popular determine their cost-effectiveness. results show consist replacing machinery more efficient ones, mainly auxiliary systems (132 out 426). outcome could guide select solutions.
