Turning organic waste into useful energy and fertiliser.
From Goma, UMOJA assesses, builds and maintains biodigesters that produce biogas and recoverable digestate for households, businesses and institutions across the Kivu region.
- 28 installations completed
- 6 areas served
- First installation in 2012
From waste to use
Five stages from organic waste to usable gas.
Collection, fermentation, purification, storage and use form one technical chain adapted to each site.
Biodigesters
Systems sized around feedstock, use and the real constraints of each site.

PAYG Mobile Money
The planned model combines a 50% deposit, monthly Mobile Money payments and a future control valve on the gas outlet.
Intervention geography
The 2012–2026 portfolio locates 28 installations across the Kivu region.
Each point represents an entry in UMOJA’s 2026 portfolio, with its period, capacity and client when documented.

Impact
Regional portfolio and results from the UMOJA site in Goma.
The 70 tonnes recovered in 2024 and the estimated 160+ kg/day requirement apply only to the biodigesters at UMOJA’s ecological mini-bakery site in Goma. The 28 recorded projects cover the full 2012–2026 portfolio.
