Biogas Plants using Household Waste

biogas 2

The main feedstock used by this plant is household waste. Waste received is crushed, sorted and the organic matter transferred into digesters to undergo methanisation.Biogas is thus generated to power engines to produce energy.
The methanisation process equally produces heat for industrial use. Mineral matter is further sorted and recycled. Digestate which is a by-product of anaerobic digestion is processed further into compost, a richer form of fertiliser.
With such a plant, arable land need not be used as landfill sites, and moreover, the local and municipal authorities would be power plant owners, transforming the challenges in waste disposal into convenient and reliable energy production.


  • Source of additonal income to local and municipal authorities e.g. electricity and compost.
  • Provides uninterrupted power to the community or national grid.
  • Creation of local employment.
  • Reduction in Green House Gas emissions.

Biogas Plants using Industrial and Agricultural Matter

Biogas 1

Through anaerobic digestion, organic matter of industrial and agricultural residue is transformed into biogas to produce gas, heat and electricity.
Our biogas plants fit very well into the West African renewable energy landscape, since industrial and agricultural residue are abundant and rich in organic matter. The biogas plants are well-suited for brewery, food and meat processing facilities.

UMAWA Ltd offers a full service Power Purchase Agreement (PPA) as well as general Engineering, Procurement and Construction (EPC) contracts.


  • Generates energy for own consumption and promote energy security.
  • Reduces risk of tariff volatility through long term PPA or ownership (EPC).
  • Optimum utilisation of industrial and agro waste that in turn prevents creation of dump sites.
