Brasserie et Limonaderies du Rwanda (Bralirwa) will secure $25m loan from the International Finance Corporation (IFC), a member of the World Bank Group, to ramp up its soft drinks production in Rwanda.
Work under the proposed expansion includes the installation of a new bottling line at the soft drinks plant in Kigali.
The expansion also includes the construction of a wastewater treatment plant and improvements in energy efficiency.
Bralirwa will also use the funds to promote local maize production and train 5,000 smallholder farmers in modern farming methods.
Bralirwa chairman Boudewijn Haarsma said: "The financing from IFC is yet another milestone for Bralirwa, and a recognition of our efforts to support economic growth in Rwanda.
"Being a partner for growth for the Africa region is at the core of Heineken's business strategy. Bralirwa aims to increase our local sourcing of raw materials needed for our products, supporting inclusive growth, and providing farmers with a reliable source of income.
"It will make an important contribution to the Heineken's 'Brewing a Better World' ambition.''
Bralirwa, the subsidiary of Heineken, manufactures beers and soft drinks, including the Primus and Coca-Cola brands.
