This work, concerns determination of energy potentials of three types of food waste in the Ivory Coast. The method used consists in carrying out a physical and chemical analysis of three types of waste, namely cocoa shell, sugar cane bagasse and oil palm seed fibers. The study of five (5) parameters show the energy potential of the three wastes. This is made possible by the knowledge of dry volatile matter (%MVS greater than 97%), total organic carbon (% COT about 57%) and dry matter (%MS between 17% and 79%), ash content (%K between 2.65% and 11.4%) and humidity (%TH between 20% and 83%).It appears from this study that these wastes have energy potentials with the lower calorific value (PCI greater than 18 MJ / kg). These data are very interesting and indicate that these wastes are recoverable by combustion or methanation. However, the humidity level is very high for two of them, notably cocoa shell and sugar cane bagasse (83% and 70% respectively). The difference between PCS and PCI shows that it will be necessary to pre-dry these wastes before combustion.
