Saint-Gobain Glass has successfully tested biomethane use at its Eurofloat plant in France, marking a significant advance in reducing emissions through regional renewable gas sources and long-term supply agreements as part of its broader sustainability efforts.
Saint-Gobain Glass has taken a promising step forward in its industrial decarbonisation efforts by successfully testing the use of local biomethane in flat glass manufacturing at its Eurofloat plant in Salaise-sur-Sanne, France. This initiative, carried out in partnership with regional energy and agricultural stakeholders, marks an important exploration of renewable gas applications in the glass industry, a sector traditionally dependent on fossil fuels.
The trials involved two distinct operations. The first, conducted with GRDF, saw biomethane injected into the local gas network through a nearby BioGNV station, helping to balance the grid during periods of low demand. The second, done with Methagora, entailed direct deliveries of biomethane by tanker truck to the plant. Produced from agricultural waste, this biomethane was generated, purified, and compressed locally in the Auvergne-Rhône-Alpes region, demonstrating a sustainable model of sourcing and transporting renewable energy even to sites not connected to natural gas pipelines. According to the company, biomethane offers a carbon footprint six times lower than natural gas, underscoring its potential as a key lever in reducing greenhouse gas emissions within the glass manufacturing process.
Saint-Gobain’s biomethane trials align with a broader strategy that includes significant commercial investments. Notably, the company has signed a 100 GWh biomethane purchase agreement with TotalEnergies for a three-year term starting in 2024. The biomethane will be sourced from TotalEnergies’ BioBéarn plant, which operates under the stringent sustainability criteria of the European Union’s RED II Directive. Through acquiring Guarantees of Origin, Saint-Gobain aims to credibly attest to the decarbonisation of its energy consumption in France within the EU Emissions Trading Scheme framework. This contract reflects a market-driven, subsidy-free approach to sourcing decarbonised energy, emphasizing the firm’s commitment to diversifying its energy mix and supporting new regional energy networks.
These developments complement other innovations at Saint-Gobain designed to reduce the carbon intensity of flat glass production. Earlier successful demonstrations include the first zero-carbon flat glass manufacturing process achieved at the Aniche plant in northern France. This was realised by combining 100% recycled glass cullet with 100% green energy from biogas and decarbonised electricity, showcasing the technical viability of integrating circular economy principles with renewable energy sources. At another facility in Herzogenrath, Germany, Saint-Gobain has tested the incorporation of hydrogen, up to 30% in fuel mix, to cut direct CO2 emissions by approximately 70%. Similarly, the company has trialled the use of bioliquid derived from the wood industry at Aniche, substituting 30% of conventional energy with this biomass-based fuel, yielding more than 80% reduction in carbon emissions (Scopes 1 and 3).
Together, these initiatives illustrate Saint-Gobain’s multi-faceted approach to industrial decarbonisation, combining renewable gases like biomethane and hydrogen, circular manufacturing practices, and alternative bioenergy sources. By leveraging local renewable resources and forming strong partnerships with regional producers and energy networks, the company is actively demonstrating pathways for the glass industry to reduce its substantial carbon footprint. This aligns with the group’s broader ambition to achieve carbon neutrality by 2050 across all scopes of emissions.
While challenges remain in scaling these technologies, especially in integrating renewable gases in energy-intensive glass furnaces at an industrial scale, Saint-Gobain’s trials and long-term agreements signal a strategic shift that could serve as a model for other heavy industry sectors committed to sustainable transformation. The feasibility of biomethane supply even in non-networked areas further broadens the potential impact, offering industrial operators flexible routes to decarbonised energy.
In sum, Saint-Gobain Glass’s pioneering biomethane trials represent a vital step in the company’s journey towards sustainable flat glass production, demonstrating not only technical feasibility but also aligning procurement and circular economy strategies to support the energy transition in one of the most challenging sectors to decarbonise.

The trials included injecting biomethane into the gas network via a nearby BioGNV station to balance the grid during low demand periods and delivering biomethane by tanker truck. This renewable gas, produced from agricultural waste, was generated, purified, and compressed locally in the Auvergne-Rhône-Alpes region before being transported to the plant. These trials confirm the feasibility of directly supplying biomethane to the glass industry, even in areas not connected to the gas network. With a carbon footprint six times lower than that of natural gas, biomethane offers a tangible solution to reducing emissions in the sector. This initiative reaffirms Saint-Gobain Glass’s commitment to a more sustainable industry by utilising local resources and collaborating closely with regional partners.

The biomethane will be produced by TotalEnergies at its BioBéarn biomethane plant, which began operations earlier this year and holds sustainable certification under the highest sustainability criteria of the European Union REDII Directive. By acquiring the Guarantees of Origin, Saint-Gobain will be able to attest, within the framework of the EU Emissions Trading Scheme, to the decarbonisation of its energy consumption in France. This contract exemplifies a purely commercial sale of biomethane, without subsidies, and demonstrates Saint-Gobain’s commitment to diversifying its sourcing of decarbonised energy and supporting the development of new local energy networks.
- https://www.glassmagazine.com/news/saint-gobain-achieves-zero-carbon-production-flat-glass – Saint-Gobain has become the first company in the world to achieve zero-carbon production of flat glass. This technological feat was achieved by using 100% recycled glass (cullet) and 100% green energy, produced from biogas and decarbonised electricity. It was implemented for one week in Saint-Gobain’s flat glass manufacturing plant in Aniche, northern France. By mobilising 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. This achievement is a clear demonstration of Saint-Gobain’s commitment to reach carbon neutrality by 2050.
