Building materials and cement manufacturer Cemex has achieved a target of burning 100% alternative fuel at its South Ferriby cement kiln.
The plant, in North Lincolnshire, has 100% of its fuel with its Climafuel fuel made from waste products over a three-day period in March.
Plant director, Philip Baynes-Clarke says: “I am immensely proud that this record has been set using a kiln that was commissioned in 1973. It proves that with the right team, skills and capital investment, plants like ours in South Ferriby can have a long and healthy shelf life, and advance our manufacturing heritage. The use of alternative fuels at South Ferriby is key to improving the environmental performance of cement making. It helps to reduce our carbon footprint, but it also drives down other key emissions.
“Our 100% record was set over a three day period in March, with the kiln remaining stable and producing good quality cement clinker. The challenge is now to exceed our 90% weekly average record and use 100% over a more sustained period.”
Cement-making is energy intensive and involves heating up kilns to at least 1400 degrees Celsius. Increasing the use of alternative fuels made from waste is therefore key to saving fossil fuels for future generations.
The alternative fuels used at South Ferriby are Secondary Liquid Fuels (SLF); made from industrial liquid wastes that cannot be recycled, such as paint, thinners, inks and varnishes, and Climafuel®; which is made from household residual and commercial waste that would otherwise go to landfill.
The Climafuel used at South Ferriby is sourced from local suppliers. Last year, more than 36,000 tonnes of waste that would otherwise be landfilled were used to make cement in South Ferriby.
