Saint-Gobain Makes Zero Carbon Flat Glass

Saint-Gobain achieved zero carbon production of flat glass and was achieved by using 100% recycled glass (cullet) and
100% green energy, produced from biogas and decarbonized electricity.

It was implemented for one week in Saint-Gobain's flat glass manufacturing plant in Aniche, France, according to a statement.

By mobilizing the network of partners developed by Saint-Gobain, the focus was placed on circularity with the use of 100% cullet from end-of-life glass from renovation or demolition sites and from production offcuts. The Group's industrial and research teams succeeded in adjusting all of the furnace's technical parameters to this dual challenge of operating with 100% recycled material and 100% biogas, while ensuring the right optical quality of the glass.

This pilot production demonstrates Saint-Gobain's capacity for innovation throughout the value chain and is a demonstration of the company's commitment to reach carbon neutrality by 2050. It complements the Group's investment announced last year to build the world's first carbon neutral plasterboard plant in Norway.
