CEMEX UK’s increased alternative fuels use results in substantial CO2 saving


Use of more waste derived fuels at CEMEX’s Rugby cement plant shows further environmental gains

6th January 2011: 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% up to 65%) 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% replacement in combination with coal at 35%, and secondly at up to 53% in conjunction with chipped tyres at 12% and coal again at 35% . It also sets out how, in CEMEX’s view, the evaluation has met and exceeded the stringent ‘critical success factor’ criteria developed by the cement industry regulator, the Environment Agency (EA), in advance of the trials.

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%) as demonstrated in the trials, up from 30% 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.

The increased use of Climafuel is also significantly helping to reduce the amount of waste material that would otherwise go to landfill. In the past 12 months, CEMEX UK has used more than 130,000 tonnes of Climafuel at Rugby plant. Based on the biomass content of the fuel, the use of Climafuel has also saved over 155,000 tonnes of CO2 in that time. This is the equivalent to saving the CO2 emissions generated by around 62,000 cars in a year.

The report is available on the company’s website - www.cemex.co.uk - at Rugby Borough Council and Rugby Library. Comments should be sent in writing, in the first instance, to Ian Southcott, CEMEX House, Rugby CV21 2DT or by email to ian.southcott@cemex.com. The closing date for comments is 31 January 2011.

Climafuel

Climafuel is an alternative fuel which is derived from household and commercial waste and could, therefore, substantially reduce what currently has to be sent to landfill. It looks like shredded paper and consists of paper, cardboard, wood, carpet, textiles and plastics that have been through a treatment process. It is a solid, non-hazardous fuel from which recoverable materials have been removed for recycling.
