Glass Forever

A commitment to a circular economy for flat glass

The climate emergency means we must challenge existing business models in order to achieve a sustainable future for everyone on our planet.

Saint-Gobain Glass is leading the industry in the design and manufacture of sustainable building glass.

Saint-Gobain Glass products are manufactured using a minimum of 30% recycled content. 

Find out more on Saint-Gobain's Green Buildings website, where you can download certificates and supporting documents, to help in the specification of Saint-Gobain Glass' wide range of high performance glass products.

For several years the focus has been the recovery and use of post-industrial glass cullet.  Now Saint-Gobain has extended the cullet return programme to recover ‘post-consumer’ glass from old windows which has, until now, typically been discarded into land-fill.


Leading sustainability in glass

Saint-Gobain’s cullet return scheme is a key initiative to achieve our target of net-zero carbon emissions by 2050. We must work in partnership with our customers and wider network of stakeholders throughout the building glass supply chain, to ensure that when possible, all post-industrial and post-consumer glass is recycled to manufacture high performance glass. 

Cullet return scheme customer support packages

The drive for change is one felt throughout the construction industry.  As a glass manufacturer it's vital that Saint-Gobain Glass helps to provide mechanisms to recycle glass, working in partnership with the glass and glazing supply chains.

Saint-Gobain Glass has created three Glass Forever cullet return scheme packages to help our glass processing customers setup and manage the collection and return of waste glass.  To find out more, please download the Glass Forever brochure.

The Saint-Gobain team are happy to help.  Please get in touch to discover more.



Cullet is the industry term for waste glass.  Building glass cullet is created throughout the glass and glazing supply chain. 

It's important that cullet recycled to make new high performance building glass is the appropriate quality and specification, which is why Saint-Gobain Glass has developed the Glass Forever Cullet Return Scheme to enable a robust, auditable process, built on strong partnerships with glass processors and other stakeholders involved in the creation of glazing and facades.

Ensuring the quality of glass cullet is vital to the successful manufacture of new high performance glass from recycled glass.  We audit all of our potential cullet return partners before setting up the recycling process on their site.  During the audit process we determine the most appropriate recycling solution and provide suitable training and equipment.

As the Saint-Gobain Glass Forever Cullet Return Scheme develops, more of our partners are installing cullet crushing machines and inviting glass processors and glaziers to their sites to recycle old glazed units into cullet.
