Bioenergy in São Tomé and Príncipe

The Bio&Energy for São Tomé and Príncipe project aimed to test the applicability of anaerobic digestion on the treatment of organic waste produced by rural community’s households of São Tomé Island. As a pilot project of proven success, systematized data of sizing, start-up and operation of anaerobic digesters will enable it to be extended to other families of the target communities.

Initial situation
In the rural areas of São Tomé and Príncipe, most of households use traditional sources of fuel such as wood or private generators to light and cook food. In rural communities up to 50 inhabitants, 89% of households use wood for cooking while 7% use oil stoves and four percent use coal. As a result of this situation, there are several problems related to the degradation of the island's forest resources and there are currently deforestation situations.

The solution is to supply sustainable source of energy through the installation of anaerobic digesters in rural communities of the districts Mé-Zóchi, Cantagalo and Lembá. The communities are involved in the daily operation of the digester through the preparation of the residues and the water to be placed in the digester. These elements are fundamental for the correct operation of the digesters and to assure the production of biogas.

Training initiatives, development of leaflets and awareness-raising panels, and information exchange between target communities of the project were some of the means used to empower and raise awareness in the communities. This project has proven that anaerobic digestion is a technology with potential of application in the treatment of the organic residues generated by Sao Tomé households to improve livelihoods.
