GRS Commodities Ltd

Developed a biogas plant which supplies electricity for off-grid areas.
2013 SEED Africa Award; European Union
Waste Management

By applying waste-to-energy concepts, GRS Commodities is able to produce and supply electricity for off-grid areas. These concepts include biogas production from animal waste and gasification of dry biomass. Biogas digester residue, which is rich in nutrients, is returned to the farmers and used as fertiliser, while surplus is sold. A new GRS gasification plant will use rice husks to produce electricity. It will power a rice mill enabling local farmers to access clean renewable energy to process their crops.

Eco-Inclusive Impacts
By applying waste-to-energy concepts, GRS Commodities is able to produce and supply electricity for off-grid areas.
  • Providing access to energy in off-grid rural areas of Uganda.
  • Increasing farmers’ incomes and livelihoods by adding value at source.
  • Transferring technology skills and knowledge in renewable energy to local people and communities.
  • Promoting and implementing clean bio-energy production technologies in Uganda.
  • Improving agricultural waste utilisation in the region.
  • Cutting CO2emissions by reducing the use of fossil fuel.
  • Contributing to local business development while enabling farmers to add value to their products.
  • Reducing farmers’ chemical fertiliser costs.
  • Mobilising local people for alternative sources of income and establishing new collaborations between producers.


The enterprise has developed a biogas plant which utilises  agricultural waste such as manure collected from local farmers, and other biowaste such as water hyacinth, to produce renewable energy for rural communities and off grid applications.  Also in development is a rice husk gasification plant. 

Norges Vel financed the procurement of the 32 kW gasification system for producing off-grid electricity.

FACT Foundation offers technical assistance and knowledge-based support in the implementation of bio-energy technology. 

Makerere University Department of Engineering and Technology facilitates the installation of the gasification plant and coordinates applied research in renewable energy.

Kalangala District Production Department coordinates production activities in Ssese and helps mobilise local farmers to collaborate with the enterprise.
