A Kenyan company that makes safer indoor burning stoves is among the 15 finalists in the running to win a $1.2m (£1m) environmental award founded by the Prince of Wales.
Charlot Magayi, who used to sell charcoal for fuel, started Mikuru Clean Stoves initiative after suffering repeated respiratory infections due to charcoal and her daughter was severely burnt by a stove.
The company provides cleaner burning stoves to reduce unhealthy indoor pollution and a safer way to cook.
Her eco-stoves use processed biomass made from charcoal, wood and sugar cane, and claims they cause 90% less pollution than an open fire. She hopes to create an even cleaner version which burns ethanol.
