Cuneo (Italy) and Osterweddingen (Germany)
AGC Glass Europe invested at its Cuneo plant (Italy) in an electric power generation system with the aim of reducing indirect emissions of CO2 and also lowering costs for electricity. The system generates power by taking the waste heat from the flue gas of the glass melting furnace and converting it into electricity. This works via an Organic Rankine Cycle (ORC) module that uses organic oil with a low boiling point (instead of water as in a steam turbine generator). The system produced 9,111 MWh in 2016.
Our plant of Osterweddingen (Germany) is also equipped with a heat recovery installation. This installation produces electricity and steam, both being reused in the plant. The system produced 10,719.4 MWh in 2016.
Roccasecca plant (Italy) is equipped with a heating recovery system for heating its warehouse.
This system recovers the heat from waste hot air from a cooling tunnel located nearby the warehouse. Compared to other solutions (e.g. conventional heaters), this system avoids any additional gas consumption and so has no impact on the total amount of CO2 emissions released by the plant. This system makes possible to recuperate about 580 MWh per year.
Cogeneration unit at Fleurus plant (Belgium)
The Fleurus automotive glass plant (Belgium) installed in 2013 a gas-fired cogeneration unit which produces two types of energy: electricity and heat. This system has energy efficiency of more than 90%.
The gas consumed by the co-generator is dedicated to 36% for electricity production, 32% for warming water, 18% for heating oil at 220°C, 2% for hot air production, and 2% for pre-heating de-ionised water.
Each of those “by-streams” is valorized on the plant itself. For example, electricity is used for mechanical power and lighting, hot water integrates the washing machines, and heat oil is used within various processes such as the autoclave, the PVB stretching, the back furnace, …
Thanks to this system, Fleurus plant already saved around 450T of CO2 in 2016.
More and more plants installing photovoltaic panels
AGC Glass Europe commits in electricity auto-production through the installation of photovoltaic (PV) panels.
The first photovoltaic panels were installed at Osterweddingen plant (Germany) and Cuneo plant (Italy) in 2009 and 2010. From then, other photovoltaic projects started at many sites: at Zeebrugge (Belgium), Mol (Belgium), Roccasecca (Italy), Fleurus (Belgium), and Moustier (Belgium). The total output of those photovoltaic installations reached 6,544 MWh in 2016.
