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."

Japan: Taiheiyo Cement has installed three BWZ bucket elevators and a Louise TKF drag chain conveyor supplied by the Hong Kong-based subsidiary of Aumund at its new power plant at Ofunato. The cement producer uses both biomass and coal at the plant.

Two elevators and the drag chain conveyor are used to transport palm kernel shells (PKS) and palm empty fruit bunches (EFB), which are used as alternative fuels in the power plant. Each has a capacity of up to 150t/hr. The conveying concept is designed so that the different materials are kept apart and enter the silo buffer tanks separately. The third bucket elevator is used for coal handling. It is a gravity discharge type BWZ-S elevator with a capacity of up to 35t/hr.

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.

Nigeria: Lafarge Africa has raised its capacity to use alternative fuels at its Ewekoro 1 cement plant to a substitution rate of 50%. Its Sagamu plant has the capacity to operate a substitution rate of up to 25%. Its alternative fuels sources include locally sourced palm kernel shells, woodchips, tyres and refuse. It is unclear whether or not the plants will be able to make use of this capacity in the near term.

“Our energy optimisation plan has proved successful with increased use of alternative fuel to offset gas shortages. Ewekoro 1 plant migrated from 100% reliance on gas and low pour fuel oil (LPFO) to about 40% use of alternative fuels at the plant,” said Michel Puchercos, the chief executive officer of Lafarge Africa in the group’s results for the fourth quarter of 2016.

The subsidiary of LafargeHolcim plans to use alternative fuels at all of its Nigerian cement plants by 2018. Ewekoro 2 will be utilising alternative fuels, Ashaka will be using alternative fuels and coal and Mfamosing is expected to be using petcoke and alternative fuels.
