True sustainability is about much more than simply producing ‘green’ products – it must be an integral part of any business. As the UK’s leading insulation manufacturer and the third largest manufacturer of insulation in the world, we take our social and environmental responsibilities very seriously.
Our focus is to constantly develop products and processes to contribute towards greener and more energy efficiency environments. We are committed to continually improving our environmental and sustainability credentials.
In August, we reached one of our key milestones in our sustainability journey. All four of our manufacturing plants in the UK are now sending zero waste to landfill. At St. Helens, Cwmbran, Queensferry and Hartlepool, a number of measures have been introduced to achieve this status.
Both at St. Helens and Cwmbran, baled glass mineral wool waste is re-used by a ceiling tile manufacturer, while mixed glass wool and incidental packaging waste is collected by a recycling partner and re-processed for use as underground bedding.
Baled rock mineral wool waste is also re-used by a ceiling tile manufacturer and we have recently built a recycling facility at Queensferry to enable any material that is out of specification to be fed back into the manufacturing process.
At Hartlepool, all manufacturing waste is recycled back into the production process, while general and kitchen waste is collected by a recycling and waste management partner company.
Back in 2009, we were producing 5000 tonnes of general waste a year which was going to landfill. To date, by improved segregation of waste at source, this figure has been reduced by over 80% to less than 1000 tonnes which is a significant difference! This unsegregated waste now goes to a recycling processor (Material Recycling Facility – MRF) and so is diverted from landfill. This means we segregate more at source and so have reduced the tonnage and any tonnage of waste we produce as general waste is still recycled.
At the beginning of 2013, we were sending 14% of waste to landfill per month. By August, this is down to 0%. Reaching zero waste to landfill is a fantastic achievement and is a clear demonstration of our commitment to improving environmental performance.
