Cement manufacturer Cemex has replaced 100% of the fossil fuel used at its South Ferriby, North Lincolnshire plant, to heat cement kilns with fuel made from waste.
According to the firm, this is likely to be a new record in the UK, where substitute fuels currently represent 35% of all kiln fuels burnt in UK cement kilns.
Cemex uses two alternative fuels: Climafuel, made from household residual waste and commercial waste; and Secondary Liquid Fuels made from industrial liquid wastes that are difficult to recycle, such as paints, thinners, inks and varnishes.
Plant director Philip Baynes-Clarke said: “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.”
Cemex set the 100% record over a three-day period in March. It is now aiming to exceed its weekly 90% average record and use 100% over a more sustained period.
