Cemex Tyre Fuel Report Shows Significant Nitrogen Oxide Reductions

Cemex UK reports significant reductions in nitrogen oxide emissions at its facility in Rugby following the partial changeover to chipped tyres as a fuel source. The company states its most recent trial met and exceeded a number of critical success factors it agreed upon with the Environment Agency.

In its 2007 Sustainable Development Report, Cemex stated “while burning tyres showed no detrimental effects to the environment, they replaced 12 per cent of fossil fuels and reduced emissions of nitrogen oxides by around 25 per cent. In 2007 we gained permission from the Environment Agency for the permanent use of tyres as fuel at Rugby, at a rate of up to three tonnes per hour.” The facility’s Environmental Index had improved by 33 per cent.

Since the use of tyres as a fuel for the cement kilns at the Rugby facility began, the company’s emissions of nitrogen oxides have fallen by a total of about 40 per cent and the use of fossil fuels has dropped 24 per cent.
