Building materials company, Cemex UK, has published a draft report following a trial programme doubling the use of chipped tyres as a fuel to a rate of six tonnes per hour at its cement plant in Rugby.
The report sets out how, in the company’s view, the trial has met and exceeded the ‘critical success factors’ for the programme, the key measure being reduced emissions from the stack.
Cemex was originally granted a permit by the Environment Agency to use chipped tyres at the rate of three tonnes per hour in February 2007 following a successful trials programme, which demonstrated distinct environmental benefits of using tyres. Tyres have been used at the plant on a continuous basis since then and have significantly reduced the on-site use of fossil fuels.
Cemex’s Rugby Works has the largest kiln in the UK and has a production capacity of 1.8 million tonnes of cement per annum.
