What if our furnaces also produced energy?

New facilities at our Pisa (Italy) flat glass plant recover the heat given off by the furnace and convert it into energy used on site.

What if our furnaces also produced energy?

Our furnaces are not just energy consumers! This can be seen in our flat glass plant in Pisa, Italy, where an innovative system is currently being tested. Various machines installed on site make it possible to recover the thermal energy of the fumes from the furnace and use it in the plant. This winter, for example, the site's finished goods warehouse will be fully heated thanks to this new system. A mechanism also converts the recuperated heat either into electricity to supply the plant's internal grid or into compressed air, required to operate the pneumatic system of some machines.

This project, which represents a €7m investment, will significantly improve the energy efficiency of the Pisa plant. It is estimated that 5,000 tons of CO2 will be avoided each year thanks to these new installations. The same system is also in pilot phase at the Chennai site in India. This initiative illustrates the Group's desire to develop its manufacturing processes to limit its energy consumption and move forward with the carbon neutrality process announced between now and 2050.
