Our high performance Glass Mineral Wool insulation solutions contain up to 80% recycled content, most of which is glass cullet from Veolia’s glass recycling facility next to our manufacturing plant in St. Helens, Merseyside, UK.
Knauf Insulation and Veolia
In 2017, we entered into a long term contract with leading resource management company, Veolia, to create a state-of-the-art facility. Now operating to its full capacity, the facility gives yearly a new lease of life to over 60,000 tonnes of used glass bottles and jars collected from households, as it cleans, separates and refines them into high purity raw materials to be used in the manufacturing of our high performance, energy-saving insulation solutions.
Veolia’s world-first facility uses the latest technology to sort and separate glass at a micro-level with exceptional accuracy, delivering an ultra-pure glass cullet to ensure the highest possible quality of insulation. The machinery includes vibrating screens for size sorting, magnets to extract ferrous materials and eddy current separators for non-ferrous materials.
The Partnership with Veolia brings many benefits
- It has reduced waste going to landfill and over 60,000 tonnes of used glass bottles and jars will be given a new lease of life each year
- We have secured our glass supply and are able to maintain the recycled materials content in the manufacture of our Glass Mineral Wool insulation solutions up to 80%
- The partnership has provided a closed loop solution and a significant investment in the mainstream circular economy
- We have substantially reduced carbon emissions from homes and the proximity of the new facility will save approximately 375,000 miles of road journeys.
