In Sub-Saharan Africa, the amount of household waste is expected to increase due to population growth and rapid urbanization. In addition to their impact on human and animal health, it has been proven that these wastes strongly contribute to global warming. Their management is nowadays a major concern in cities and countryside. The study was carried out to evaluate the prospects for the valorization of green kitchen waste in animal feed. A system for separating green kitchen waste from other household waste was set up in about thirty households in the commune V of Bamako. After the installation of the trash cans, weekly visits were made to the households to characterize the contents of the trash cans before weighing them. The results show a strong variability in the production of green kitchen waste according to the socio-professional category of the household head. The weekly production of this waste is between 0.46 and 1.90 kg for households of 2 to 16 people. The bromatological analysis carried out on a mixed sample shows that they constitute a potential feed resource for urban and peri-urban livestock with feed values that are between those of forage and oilcake. The valorization of these sub-products in livestock feed could contribute to the sanitation of our neighborhoods but also to the reduction of methane emissions in municipal dump sites.
