Adélaïde Lareba Ouedraogo, Dominique Bonkoungou, Eric Simonguy, Eric Korsaga, Sami Florent Palm, Sié Kam, Achille Olivier Ravoninjatovo, Dieudonné Joseph Bathiebo
Madagascar is well endowed with energy resources, particularly renewable energies.
These include watercourses for hydropower, solar irradiation for photovoltaic
solar energy, wind for wind power, as well as exploitable surfaces for
bioenergy, although these are currently little exploited. What’s more, the electricity
distribution network c(...)

Gasification of Raw, Roasted and Carbonized Cashew Shells Using and Fixed Bed Co-Current Gasifier
Bénéwindé Edwige 2ème Jumelle Ouédraogo, Gado Harouna Ibrahim, Wend-Kuni Gisele Bilgo, Tizane Daho, Oumar Sanogo, Antoine Bere
The present study focuses on the improvement of gas quality by gasification of raw and cashew shells heat treatment by roasting and carbonization. The gasifier is a fixed-bed co-current batch mode, with a throat. It has a thermal power of around 30 kW. It meets the need for low electrical power of the order of 10 kWe. It has a double wall with(...)

Monitoring of PM2.5 Using Well-Calibrated Low-Cost Sensors over One Year in Burkina Faso
Bernard Nana, Garima Raheja, Issoufou Ouarma, Haro Kayaba, Woro Yomi Gounkaou, Tizane Daho, Antoine Béré, Abdelwahid Mellouki, Daniel M. Westervelt
Air pollution causes more than 8.34 million premature deaths worldwide. Most of these deaths occur in the Global South, particularly in Africa. However, the means of observing this air pollution in these countries are lacking. Knowledge of pollutant concentration levels and their distribution in time and space is inadequate or nonexistent in m(...)

This study aims to explore anaerobic co-digestion (AcoD) of cassava (EUM) and
poultry (FP) effluents using one inoculum/substrate ratio (30%) and three EUM vs. FP
substrate composition ratios (25:75, 50:50, and 75:25). The AcoD process was therefore
designed for 20 L batch digesters, under mesophilic conditions, with less than 5% total
