Building materials company, Cemex UK, has published a draft report for public consultation, which shows that more than doubling the levels of Climafuel (from 30 per cent up to 65 per cent) at its Rugby plant in Warwickshire has environmental benefits. Climafuel is an alternative fuel derived from residual household and commercial waste, which is used to heat the cement kiln in Rugby. The report provides an evaluation of using two increased levels of Climafuel – firstly at up to 65 per cent replacement in combination with coal at 35 per cent, and secondly at up to 53 per cent in conjunction with chipped tyres at 12 per cent and coal again at 35 per cent.Following a two month public consultation, Cemex hopes to secure the permanent permission for the use of Climafuel at the maximum rate (up to 65 per cent) as demonstrated in the trials, up from 30 per cent from the plant’s previous permit. The draft report demonstrates that the increased use of Climafuel has produced positive results. It shows that during the evaluation there were no breaches of existing emission limit values, and that the overall environmental impact is reduced when Climafuel is used to replace traditional fossil fuels such as coal. In the past 12 month, Cemex UK has used more than 1,30,000 tonne of climafuel at Rugby plant. Based on the biomass content of the fuel, the use of Climafuel has also saved over 1,55,000 tonne of CO2 in that time. This is the equivalent to saving the CO2 emissions generated by around 62,000 cars in a year.Contact: Cemex UK Operations LtdTel: +44 (0)845 155 9294;Fax: +44 (0)1788 517133Email: gb-enquiries@cemex.com;Website: www.cemex.co.uk
