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 …

Knauf celebrates win at the 2016 CMA Awards in London

Knauf has emerged victorious in the Best Social Media Campaign category for the Construction Marketing Awards for its light-hearted Facebook project which successfully grew Knauf’s online following.

With a summer filled with major sporting events to capitalise on, the Summer of Sport tapped into public enthusiasm by creating whiteboard videos, as well as offering sport-related prizes.

The fun and innovative “whiteboard” videos referenced some of the summer’s majo…

Curbing energy waste in buildings must drive new energy efficiency proposals

The European Commission’s ‘winter package’ of energy proposals, due before the end of 2016, will be multi-faceted and wide-ranging, but Knauf Insulation only wants one thing — an ambitious commitment to tackling energy waste in buildings.

“Europe must put energy efficiency at the heart of any future decisions on our energy system and that means a historic commitment to stopping energy waste and improving Europe’s buildings this December,” said Sîan Hughes, Director of External Affairs for Knauf Insulation

Speaking on the occasion of Renovate Europe Day, Sîan stressed that an ambitious Europe-wide building renovation programme would have a positive impact on Europeans for generations to come.

“Buildings account for 40% of Europe’s energy use and 36% of its emissions. A genuinely visionary Europe-wide renovation programme will cut energy use and honour international climate commitments and, perhaps more importantly, create millions of jobs and drastically improve livings standards for …
