The latest recycling data from Morley Glass shows that the company has now generated more than 3,000 tonnes of cullet through the crushing of post-consumer IGUs it collects from its integral blind customers.
Morley Glass’s scheme, which pioneered the recycling of post-consumer IGUs at scale when it first launched in 2021, allows installers to divert the IGUs extracted from windows and doors during replacement projects away from landfill. In addition to helping installers save money on waste disposal costs, the scheme helps glass manufacturers reduce the need for virgin raw materials and cut energy use, as well as generate funds for charities and community projects.
As of August 2026, Morley Glass has now produced 4,332 bags of cullet directly through the crushing of old IGUs. Approximately 1 tonne of cullet is generated from every 2 bags of cullet, but this can vary widely, which means the scheme has now surpassed the 3,000-tonne level.
The contribution this makes to energy savings for the industry is illustrated by the fact that 1 tonne of cullet saves enough energy to power an average home for 6 months. To date, the volume of cullet generated has equated to 1,674 years of energy saved for an average home.
Carbon emissions have also been cut as a direct result of the recycling scheme, with 2,220 tonnes of CO2 saved from being emitted into the atmosphere. And the savings on raw material use are significant too, with the demand for virgin sand – the main raw material for glass manufacturing – cut by an estimated 4,641 tonnes to date.
Ian Short, Managing Director of Morley Glass, said: “We’re really proud to have reached the 3,000 tonne milestone in our glass recycling scheme. It is so important that the industry continues to treat post-consumer IGUs as a raw material for re-manufacturing, rather than something that can simply be disposed of and forgotten about.
“Thank you to all our customers who are making the effort to put their old IGUs to one side so we can collect them when we deliver their new Uni-Blinds® integral blind units. Many of our customers are already into a routine that seems as normal as recycling glass, metal and plastics at home, which means we will be able to maintain healthy volumes of cullet production – and we will continue to monitor and publish the data.”
In addition to the resource savings that the Morley Glass scheme provides, it also generates funds for charities, groups and individuals working on projects to improve their local communities through its GreenVision fund. As every penny generated from the cullet goes into the fund, 452 grants have been provided to date to community projects with environmental or social benefit, with causes ranging from school vegetable growing projects and youth clubs to support for budding athletes and a cat rescue charity.
