Mukuru Clean Stoves

Country:
Kenya
Nominated by:

Across Africa, 700 million people use traditional cookstoves, which emit harmful chemicals and lack safeguards. Mukuru Clean Stoves are different.

Their Story

Growing up in Mukuru, one of Nairobi’s largest slums, for years Charlot Magayi sold charcoal for fuel. That charcoal was the cause of regular respiratory infections for her and her neighbours. Then, in 2012, her daughter was severely burnt by a charcoal-burning stove. Seeking a better solution, in 2017 she founded Mukuru Clean Stoves.

Rather than burning dangerous solid fuels, Mukuru Clean Stoves use processed biomass made from charcoal, wood and sugarcane. This burns cleaner, creating 90 percent less pollution than an open fire and 70 percent less than a traditional cookstove. They are cheaper too, costing just $10 and halving ongoing fuel costs.

Today, 200,000 people in Kenya use Mukuru Clean Stoves, saving $10 million in fuel costs and saving lives too. In rural areas, where young girls often spend three hours a day collecting firewood, they also save precious time. A female-founded business with mostly female staff and distribution agents, Mukuru is empowering women to make a living by making a difference.

Magayi plans to create an even cleaner stove that burns ethanol.  In three years, she hopes to reach one million customers. In ten years, she plans to reach ten million people all over Africa.
