Gypsum industry news

UK: The Carbon Trust has awarded Knauf UK the Carbon Trust Standard for Carbon in recognition of its success in reducing its carbon emissions. The Carbon Trust is the world's leading independent certification organisation and the award is a step forward for the gypsum industry as a whole.

"We're particularly proud to have achieved the Carbon Trust Standard because it reflects the company's commitment to sustainability throughout its operations," said Lorna Stork, Knauf UK's sustainability manager. "We manufacture products that are energy-intensive to produce, so this achievement not only owes a lot to improvements at factory level, but also shows that we believe in managing carbon and energy use in other areas."

Knauf has re-formulated the composition of its wallboard to reduce water content and the energy consumption required to dry them. The result is that, across the company, the average board weight has fallen by 2% over the past five years, leading to a cut in energy consumption of over 5%. Knauf has also achieved considerable energy savings in the drying process. 10GWh of gas were saved at the company's Kent facility and a further 2.8GWh at its Hull plant. These savings have been reinforced with other initiatives, including the implementation of ISO 50001, energy targets for board production, monitoring programmes and sourcing lower moisture raw materials.

Knauf has also examined other elements of its business in terms of carbon use, including handling and distribution. There have been marked improvements in Knauf's own energy consumption by forklifts and other site vehicles due to monitoring of fuel usage and training staff on how to operate the plant and equipment optimally.

"Knauf's attitude towards carbon reduction is commendable and the company's efforts have led to a significant reduction of over 5%. The company is an example of what can be achieved going beyond business-as-usual and innovating to improve your environmental impact," said Darran Messem, managing director of certification at the Carbon Trust. "Achieving the Carbon Trust Standard is one thing, but keeping it is a constant task, not one that is achieved by a single initiative. As a company, we are committed to that aim and to everything that it implies."
