Project Methane Africa, Tanzania

KEYWORDS: Tanzania, sustainable development, environment, agriculture, biogas, Africa, renewable energy, biogas, economics, social

Project carried out in 2003 by DUCLOUS Jerome and GUILLAUD Landry, 2 pupils of EIGSI, Engineering School of La Rochelle. Their work is quite exceptional since 2 students went to Tanzania to implement and help the realization of biogas plants within an NGO. A documentary film was also produced.

Executive Summary

Tanzania is a country in East Africa whose political capital is Dodoma, the country's center. NGOs (Non Governmental Organizations) have a key role in improving the daily life and the development of Tanzania since the government can not afford to meet the needs of the population.

We conducted our technician internship with MIGESADO team, one of the many NGOs Dodoma. MIGESADO develops decade anaerobic digestion and energy alternatives throughout the Dodoma region. This project involves the production of biogas receiving the organic matter and produce biogas (methane) and compost. MIGESADO built in over 600 since its inception, as well as tanks rainwater retention, and craft stoves ... Regarding originally, the owners of some cows, the project is currently applied to human structures as in some schools, prisons, government offices, businesses, etc.

Anaerobic digestion is a very old method of turning organic waste into gas and odorless natural compost. It is a renewable, safe, applicable always and everywhere. MIGESADO was inspired by an Indian digester model with several changes related to cultural and environmental differences.

During this internship, we discovered the importance of MIGESADO for sustainable development of the Dodoma region. There is real progress in the areas of agriculture, energy, environment and social.

From the environmental point of view, methane is a greenhouse gas produced naturally in the anaerobic process of organic matter transformation. By burning for consumption, it transforms the CO2 is 20 times less polluting. Moreover, this use avoids deforestation, and therefore the depletion and the inoperability of the soil. Anaerobic digestion also produces a completely odorless compost, excellent fertilizer and natural pesticide.

From the social point of view, this process provides the women of exhausting work, estimated at two hours a day, cutting and transporting wood to their homes. It is also a real progress in the quality of life for cooking quickly and without suffering from smoke.

From an economic point of view, the construction of a digester is expensive compared to the Tanzanian living standards, but this investment is very profitable in the long term. User fees are almost zero since the raw material is waste and hard materials in construction ensures longevity of the structure without maintenance.

Our training began with the discovery of MIGESADO project and adaptation to Tanzanian culture. We then participated in the technical improvement of biogas and communication of the project.

Beyond this report and the corresponding defense, our project continues by making a video report showing MIGESADO our partners. Thereafter, we will try to find new donors that will allow this necessary and ambitious project to continue.
