Sierra Leonean Innovator Margaret Yainkain Mansaray Shortlisted For The 2023 Africa Prize For Engineering Innovation

Out of 15 African innovators, Sierra Leonean innovator and founder of Smart Green Stove, Margaret Yainkain Mansaray has been shortlisted for 2023 UK’s Royal Academy of Engineering Africa Prize for Engineering Innovation.

Margaret’s Smart Green Stove is an efficient non-electric cooking device designed to reduce greenhouse gas emissions and health risks that disproportionately affect women and girls in Africa. It also saves time spent cooking and reduces energy use by 70%.

The stove burns briquettes made from recycled local materials such as coconut and jelly shells which are usually discarded. Its frame is made from recycled metal which houses a ceramic insulator made of clay mixed with waste coconut fibre and sawdust.

“My team and I are working tirelessly to uplift women and girls by addressing time and energy poverty. This will allow them greater control of their productivity, because time is money. I’ve always been the only woman in a room full of men, and so one of my aims is to educate women and girls, specifically on the role engineering can play in improving their lives.”
