As BUA Boosts Nigeria’s Cement Production Capacity
“Following implementation of this new directive, I am pleased to note that the production capacity of the cement industry in Nigeria has doubled from 30 million tonnes in 2014 to about 60mThe consumption of cement in Nigeria has increased to 18.5 million metric tonnes per annum (MMTPA) due to rapid urbanization and industrialization. Despite the huge demand for cement in Nigeria, domestic production was unable to meet the demand; hence the country relied on importation of cement to meet domestic construction needs.
