Achieve up to 2 hours fire protection on ductwork with Knauf's Rocksilk Pyroduct Slab

Knauf Insulation and Veolia in deal to invest £10m at St Helens plant

Mineral wool insulationmanufacturer Knauf Insulation has agreed a long-term deal that will see £10m invested in a new glass cullet processing facility, next to its manufacturing plant in St Helens.

The new facility, which will be operated by resource management company Veolia, will create 18 jobs once complete at the end of 2017.

Staff at the new facility will clean, dry and refine tens of thousands of tonnes of recycled glass, to be used by Knauf Insulation in the production of its energy saving insulation products.

The crushed glass cullet will be melted and spun into the glass mineral wool products it sells to housebuilders and construction firms.

The process of using glass cullet uses less energy than traditional methods of manufacturing mineral wool insulation, with the associated energy saving generated from recycling a single glass bottle equal to powering a 100-watt light bulb for almost an hour.

John Sinfield, managing director at Knauf Insulation Northern Europe, said: “The …
