In Guinea, several communities lack energy supply for daily household needs, including cooking. People often resort to burning wood to fill these energy gaps. The deforestation generated is becoming increasingly worrisome, with multiple environmental consequences. In this context, an alternative to abusive wood cutting must be found in order to contribute to the fight against deforestation. This paper proposes a new model for ecological charcoal production using pig manure. The pig manure collection, weighing, drying, carbonization, crushing, sieving, kneading, mixing with the addition of binder, compacting and drying of the briquettes are the different process which allowed us to produce this ecological charcoal trough pig manure. With 9kg of carbonized powder, we obtained 120 briquettes of pig manure charcoal. Then a physicochemical characterization of the ecological charcoal briquettes produced from pig manure was made, the density and humidity rate determined are respectively 0.88g/cm3 and 54.84%. Finally, we carried out a combustibility test of the ecological charcoal produced. To do this, a comparison of the physicochemical properties between our ecological charcoal produced and the wood charcoal consumed in the city of Nérékoré. The results showed that the manufactured ecological charcoal (charcoal from pig manure) is denser and more humid than wood charcoal. In terms of boiling temperature, pig manure charcoal reaches its maximum temperature later than wood charcoal. The maximum temperature (80.6°C) is reached in 30 minutes for ecological charcoal (pig manure charcoal) and (92°C) in 15 minutes for wood charcoal.
