Glass Cullet

imageThe UK's leading cullet return scheme offered by Saint-Gobain Building Glass.


Using recycled cullet has a direct and positive effect on the environment and the reduction of energy used in the glass manufacturing process; but collecting it efficiently can be a significant challenge.


To help alleviate this challenge, in 2001 Saint-Gobain Building Glass created an innovative cullet return scheme, enabling the utilisation of over 30% recycled material in the manufacture of float glass - more than any other UK float glass producer. This

was the first scheme of its kind that was offered by a flat glass manufacturer.


To date, the scheme has allowed Saint-Gobain Building Glass to reduce its energy consumption by

8%, its raw material consumption by 25% and its CO2 emissions by 10%.



 The scheme recycles in excess of 40,000 tonnes annually, which has led to a  reduction of NOX emissions and raw material usage. Additionally, the scheme has  helped to divert thousands of tonnes of waste glass from landfill sites. Prior to  2005, only float glass could be recycled; but today, coated and mirrored glass can also be included, representing a major breakthrough for Saint-Gobain Building Glass and the environment.


 The process is simple; customers and non-customers of Saint-Gobain Building Glass fill reusable bags with their cullet (including glass not supplied by Saint-Gobain Building Glass) and return it to our site on empty stillages. By returning cullet using an inloader already on the road has helped to reduce over 1 million haulage miles from UK roads, subsequently reducing our CO2 footprint.
