In Kenya, the posho mill is more than just a machine—it's an institution. These maize grinding mills represent economic empowerment, food security, and community resilience. From bustling urban neighborhoods to remote rural villages, posho mills provide the essential service of transforming maize into the staple food: unga wa ugali (maize flour). With maize consumption deeply embedded in Kenyan culture and the agricultural sector employing over 75% of the population, the posho mill business remains one of the most viable and widespread small enterprises across the country.
