Saint-Gobain Achieves Zero-Carbon Production of Flat Glass

Published on: 20 May 2022 06:38 PM

Saint-Gobain, a world leader in light and sustainable construction, has become the first player in the world to achieve zero-carbon production of flat glass.

Last week, this technological milestone was achieved by utilising 100% recycled glass (cullet) and 100% green energy generated from biogas and decarbonised electricity. It was tested for a week at Saint-Gobain's glass plant in Aniche, France.

The focus was on circularity, with 100 per cent cullet from end-of-life glass from renovation or demolition sites.  The Group's industrial and research teams were successful in adapting all of the furnace's technical parameters to meet the dual challenge of operating on 100% recycled material and 100% biogas while maintaining proper glass optical quality. This pilot production shows Saint- Gobain's capacity to innovate across the whole value chain.

This accomplishment demonstrates Saint-Gobain's commitment to becoming carbon neutral by 2050. It follows the Group's announcement last year that it would invest in the world's first carbon-neutral plasterboard facility in Norway.

It reinforces the Group's position as the global leader in light and sustainable building and its leadership role in assisting in the transition to a carbon-neutral economy.
