Founded in 2014 with roots tracing back to Gramax Biogas, Greenleaf has spent over a decade designing and installing biogas digesters, distributing biogas appliances, and training the households and farms we work with. We're based in Kiambu and Nairobi, with installations reaching communities further afield, from Kisii to Kisumu and Busia.

Every system we build turns organic waste into two things at once: clean cooking gas that cuts smoke exposure and firewood dependence, and nutrient-rich bio-slurry that goes straight back onto the farm. It's a circular model — energy and soil health from the same waste stream.
