Optimal Greening Foundation (OGF) is a Nigerian non-profit organization established in 2020 by CEO Osen Iyahen. The foundation focuses on providing sustainable water, sanitation, and hygiene (WASH) services, along with renewable energy and environmental sustainability solutions, to underserved and marginalized communities across Africa. Its core mission is to restore human dignity by treating health, hygiene, and safe water as fundamental rights rather than luxuries.
OGF operates in Lagos, Nigeria, and manages projects that include WASH facilities and solar-powered water systems. The organization emphasizes community accountability, long-term infrastructure sustainability, and the use of monitoring, evaluation, and learning (MEL) systems to improve program effectiveness and decision-making.
