SOSUMO (Société Sucrière du Moso) is a company that grows and refines sugar in Burundi.

[1] The third five-year plan for economic and social development of Burundi, issued in the early 1970s, include the Moso sugar project to improve the economy of the southeast region.

[5] Private neighborhoods were also built in what developed into an urban center with a regional hospital and an airfield, banks and other institutions.

[3] In December 2019 SOSUMO validated a study by experts from the Institute of Agronomic Sciences of Burundi (ISABU) that recommended using new techniques and types of fertilizer to boost production.

[11] In March 2023 it was decided to expropriate rice farmers in the Mukazye, Mazimero, Gatonga, Kinwa and Nyamikungu marshes of the Commune of Giharo, Rutana Province, and transfer the fields to SOSUMO to grow sugar cane.

[13] In May 2022 Emmanuel Sinzohagera, Speaker of the Senate, visited Rutana Province and met executives of SOSUMO in the Commune of Bukemba to discuss plans for expansion and modernization of their operations, which were underway to meet growing demand.

[14] In September 2022 planned growth of cane production meant the factory would also have to be expanded and equipped with modern equipment, and SOSUMO was seeking funding for this, but in the interim planned to repair the boilers after the production campaign ended in December.

[8] In April 2024 the managing director told the workers that the Indian company that was to repair the broken boiler, turbo-alternator and centrifuge had been slow to arrive, which would delay the start of the sugar production campaign.

[16] Sosumo transports sugar to warehouses in Gihofi, Ruvumera market in Bujumbura, Ngozi and Gitega.

He recommended that SOSUMO monitor the amounts delivered to wholesalers and then through distributors to retailers, and punish any unauthorized trading.

[18] The company did not have the capital needed to rehabilitate its equipment and agricultural machinery, or to expand its factory and sugar cane plantations.

In November 2018 the Burundian parliament therefore voted by 100 to 1 to change the management structure and let private investors acquire 53.68% of the share capital for US$20 million.

[3] On 29 December 2023 the Burundian head of state said he had visited the Sarrai Group in Uganda, which he described as a very efficient company.
