Morley Glass has surpassed the 3,000-tonne mark for recycled glass cullet, marking a major milestone for its post-consumer insulating glass unit (IGU) recycling scheme.
Launched in 2021, the scheme enables installers to divert old IGUs removed during window and door replacement projects from landfill. The collected units are crushed by Morley Glass, producing cullet that can be returned to glass manufacturing as a secondary raw material.
As of August 2026, the company has produced 4,332 bags of cullet, equivalent to more than 3,000 tonnes. Morley Glass estimates that approximately one tonne of cullet is generated from every two bags, although actual quantities vary depending on the material collected.
The environmental impact is significant. According to the company, the recycled glass has saved an estimated 2,220 tonnes of CO₂ emissions and reduced demand for virgin sand by approximately 4,641 tonnes. The energy savings are equivalent to around 1,674 years of electricity consumption for an average home, based on the company’s calculation that one tonne of cullet saves enough energy to power a home for six months. 
The initiative also supports communities through the GreenVision fund. Revenue generated from the cullet has so far financed 452 grants for environmental and social projects, including school gardening initiatives, youth clubs, sports development and animal welfare.
