Nigeria: Dangote Cement plans to upgrade its Ibese cement plant in order to use biofuels in its cement production. The Nigerian Guardian newspaper has reported that the plant will receive a pneumatic feeding system for the kiln of its Line 2. Dangote Cement plans to use palm kernel shells, rice husks, coconut shells and sugarcane bagasse, along with sawdust. The producer says that this will reduce its CO₂ emissions by 5.2% and help to divert local agricultural waste from incineration.

Project head Sumaila Muhammed said “We carried out alternative fuel resource mapping within our host communities. We decided to collect these wastes and convert them into valuable energy resources as smokeless, renewable biofuel."

US: National Cement Company of Alabama has reported that the new kiln line at its Ragland cement plant will reduce the plant’s CO₂ emissions by 40%. Its energy consumption will also fall by 30% as a result of the upgrade. The new line includes a 78m-high homogenisation silo, vertical crusher, five-stage preheater and automated clay storage system. AF used in the kiln will include waste tyres, woodchip and sawdust. The new kiln will help in the Ragland cement plant’s transition to 100% Portland limestone cement (PLC) production by 2023, further diminishing its carbon footprint.

Vicat CEO Guy Sidos said "Our ambition is to use AF in all our cement plants around the world. In addition to eliminating fossil fuel energy and replacing it with recycled regional waste, our investments contribute directly to local development. We are proud of the modernisation and transformation of our Ragland site, which was our very first acquisition outside France in 1974."

Uganda: Geocycle has officially launched its presence in Uganda. The waste management subsidiary of LafargeHolcim will collect and burn waste fuels in the kilns of local cement producer Hima Cement, according to the Daily Monitor newspaper. At present Geocycle coordinates the management and use of agricultural waste fuels for Hima Cement, including coffee husks, rice husks, bagasse, palm kernels and sawdust. It has also started working with the Fort Portal Municipality to source municipal waste streams.
