Abstract—Waste management and the energy supply are two major challenges that human have recorded for millennia. The technologies for recovery of energy from wastes can play a vital role in mitigating the problems. The biomass gasification is one of the principal technologies of heat treatments, which offer the possibility of producing renewable energy called "synthesis gas" consisting essentially of combustible gases such as methane and hydrogen. The aim of our work is the realization and testing of a small up draft gasifier. The woodwork of the commune of Adrar generates an important quantity of sawdust, which is neither treated nor valued, of this fact, therefore we have chosen as the substrate for this study. In addition to the interesting energy characteristics (Low Heat Value LVH =4779.17 kWh/ton) the sawdust does not take part in the increase in the content of atmospheric CO2. The gasification prototype realized during this study allowed a production of a flammable gas in a temperature reached 390°C with a reduction ratio of more than 87% by mass.
