Saint-Gobain has become the first player in the world to make zero carbon flat glass by using 100% recycled glass (cullet) and 100% green energy, produced from biogas and what it called decarbonised electricity.
It achieved its breakthrough last week at its factory in Aniche, northern France, the company said in a press release today, terming it a pilot project.
The company and its partners got the cullet from end-of-life glass from renovation or demolition sites and from production offcuts.
Engineers adjusted the furnace’s technical parameters to cope with 100% recycled material and 100% biogas while ensuring the glass’s optical quality.
Saint-Gobain has committed to reach carbon neutrality by 2050.
