Fighting food waste in Africa with biofuel-run Sparky Dryer

January 7, 2018 |

In Uganda, engineering graduate Lawrence Okettayot is addressing food waste with his new Sparky Dryer, which is a food dehydrator that runs on biofuel from a farmer’s garden and burns with zero-carbon emissions. The dehydrator helps farmers avoid food loss and food waste due to spoilage, which is an issue in Uganda for many farmers. The dryers start at about $80 and can dehydrate 10kg of mango in two hours running on 2kg of biofuel.

“Because in Uganda 80% of the population don’t have access to electricity, they can put anything from their garden, like leaves, sticks, anything that is not of use at the minute, and the catalytic converter converts the toxins into good gases so the gasification process has zero carbon-dioxide emissions,” Okettayot told The Guardian.
