Combustibles briquettes are energetics resources, which could be use to substitute other types of energy. Optimization of energetic efficiency of combustible briquette lead us to made it so that to contribute to thrift wood resources and local sustainable development. Valorization of dry dead leaves of Azadirachta indica associated to dry stems of Sorghum sp. upon to made combustibles briquettes is the object of this work. By using mechanics process, production of combustibles conducts us to show their physicals characteristics where it average density is 0.34±0.09 and average ratio surface/volume is 22.68±3.97cm-1. Chemicals characteristics permit us to identify 7.68±0.32% as moisture content when the fixed carbon content average is 91.00±4.83%. Inflammability test demonstrate that maximal duration of inflammation is 0.19± 0.02 minutes with time limit of 0.09± 0.02 minutes. Combustion test show that combustion duration average is 19.03±7.07 minutes with 66,50±9,18% as loss mass of combustible briquette.
