Saint-Gobain achieves Carbon-Zero milestone using Recycling and Biogas at Glass Plant

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

The flat glass was produced at Saint-Gobain's manufacturing plant in Aniche, northern France. The firm leveraged its network of partners to produce the zero-carbon glass.

The manufacturing process involved the use of 100% cullet from end-of-life glass collected from demolition sites and production offcuts. The furnace's technical parameters were adjusted to the challenge of operating with 100% biogas and 100% recycled material, while maintaining the appropriate optical quality of the glass.

The achievement aligns with the firm’s commitment to reach carbon neutrality by 2050.

Last year, Saint-Gobain announced an investment to build the world’s first carbon neutral plasterboard plant in Norway.

The company has a presence in more than 75 countries, producing materials for the industrial and construction industries. Saint-Gobain employs more than 166,000 employees.

In 2015, it sets its first ambitious environmental targets of 20 percent reduction in carbon emissions and 80 percent reduction in water discharges. Two years ago, Saint-Gobain announces its target of carbon neutrality.
