Cimerwa Cement Limited

The main factory of the company is located in Muganza Sector, in the town of Bugarama, in Rusizi District, in the Western Province of Rwanda.[3] This location is approximately 36 kilometres (22 mi), by road, south-east of the city of Cyangugu, the largest urban center in Rusizi District, and the location of the district headquarters.[4] The coordinates of the main factory of Cimerwa are: 02°36'25.0"S, 29°01'03.0"E (Latitude:-2.606944; Longitude:29.017500).[5] The company also maintains offices in the city of Kigali, the capital and largest city of Rwanda.[3]

The installed factory capacity is 600,000 metric tonnes annually. Prior to 2018, the factory was performing at under 60 percent capacity (approximately 350,000 metric tonnes annually).[2] In 2018, the factory was upgraded and increased its performance to approximately 74 percent of installed capacity (approximately 441,223 metric tonnes annually).[6] The upgrade cost US$3.3 million, and lasted 26 days.[7]

Prior to the 2018 upgrade, Cimerwa could produce 27,000 metric tonnes monthly, or approximately 54 percent of the 50,000 metric tonnes needed monthly to satisfy Rwanda's cement needs.[8] With production of an expected 441,223 metric tonnes after the upgrade, it is expected cement importation into Rwanda will reduce.[6]

The factory uses imported coal from Malawi and Tanzania, to fuel its kilns.[7]

The company was established in 1982, with capacity of 50,000 metric tonnes annually. It was managed by a Chinese company, CBMC, under a "build-own-operate-transfer" model. During the 1994 Rwandan genocide, plant operations were suspended and 53 employees died. In 2001, plant capacity was increased to 100,000 metric tonnes annually.[9]

In 2006, Cimerwa was privatized under the Rwanda Investment Group. Ownership transferred to several Rwanda-based institutions. PPC Limited acquired a 51 percent ownership in Cimerwa, for US$69.4 million in 2013. In 2015, the company assumed a new corporate identity to reflect the new ownership.[9]
