On a month-to-month basis, output climbed 53.4 percent from July 2025, according to the National Institute of Statistics of Rwanda (NISR). The figures highlight rising demand from infrastructure and real estate projects.
Although construction activity itself is not directly measured in the Industrial Production Index (IIP), its impact is evident. Strong building demand is lifting production of materials.
The subsector's gross value added (GVA) grew from Frw 22.4 billion in 2017 to Frw 68.1 billion in 2024, an increase of 204 percent. In 2024, non-metallic minerals accounted for about 6 percent of total industrial GVA and nearly 9 percent within manufacturing.
Electricity generation, a critical input for cement kilns and ceramics, rose 7 percent year-on-year in August 2025. This growth supported the expansion in mineral products output.
Key manufacturers
CIMERWA Plc, based in Rusizi District, operates Rwanda's largest integrated cement plant, with a capacity of about 600,000 tonnes per year. It exports cement to neighbouring markets such as the Democratic Republic of Congo and Burundi.
In July 2024, CIMERWA acquired Prime Cement Ltd's operational assets in an off-market deal while the government kept Prime Cement's outstanding liabilities.
Prime Cement had been operating a modern plant in Musanze District, making product lines such as Ramba 42.5N and Rutare 32.5N. After the acquisition, these assets fall under CIMERWA's control.
ANJIA Prefabricated Construction Rwanda, inaugurated in August 2023 in Muhanga District, represents a new generation of producers. The company combines prefabricated systems with cement-based components to serve the fast-growing infrastructure sector.
Together, these firms illustrate Rwanda's strategy of promoting import substitution and value addition in building materials.
Experts note that this growth could accelerate further if upcoming large-scale housing programs, industrial parks, and public works proceed as scheduled. For manufacturers, it represents a critical opportunity to invest in cleaner technologies and value addition, ensuring Rwanda's 'cement boom' becomes a sustainable driver of long-term industrialisation.
