The Environment Agency (EA) has granted permission for CEMEX to use a waste-derived fuel, Climafuel, at its Barrington cement plant in Cambridgeshire. A trial to replace 20 per cent of fossil fuels resulted in significant environmental benefits for the company, including a 13 per cent reduction in emissions of oxides of nitrogen.
Climafuel is an alternative fuel, which is derived from household residual and commercial waste. Resembling shredded paper, the fuel consists of paper, cardboard, wood, carpet, textiles and plastics that have been through a treatment process.
Since the introduction of Climafuel 10,000 tonnes of waste that would otherwise be land filled been used to make cement in Barrington. Based on the biomass content of the fuel it saves nearly 13,000 tonnes of CO2, the same emissions, produced by 4,700 cars in a year.
CEMEX welcome the EA decision, which is key to improving the company’s environmental performance and will help to ensure that quality cement from the plant is produced as sustainably as possible. To secure the permit, the plant demonstrated compliance with six critical success factors that had been agreed with the EA in advance.
The Barrington plant already has permission for another alternative fuel, Secondary Liquid Fuel (SLF), which replaces up to 40 per cent of the fossil fuels required for the cement-making process. This means that when used together SLF and Climafuel can substitute up to 60 per cent of the fuel used to heat the kiln. This will significantly reduce the carbon footprint of the plant.
