This article is on the study of the C/N ratio in the domestic biogas usable wastes. The global objective was to detect the concentration of nitrogen and carbon, the determination of the ratio as well as their connection in the different types of biogas usable wastes. The authors took samples, tested and studied it in laboratories in Lwiro and others were done in the National Program of Biogas for Burkina-Faso 2005. To observe the concentration and connection, the correlation test wad used.  The Kjeldhal method and the statistic one have allowed attending results. The test for the animal and human wastes gave a correlation of 0.362 and 0.95 respectively. It showed however no correlation for the agricultural wastes with 24, because this numeral wasn’t in the space of -1 and 1. The average C/N ratio was is 24, 9 for first type and 74 for the second type of wastes.

Keywords: C/N ratio, organic waste, domestic biogas.
