Bioenergy: Organic Waste Reactors
Organic waste like dead plant material, manure, or kitchen waste can be turned into a gaseous fuel. It’s produced by fermentation of these biodegradable materials. Biogas can be used as fuel for cooking, for example, or in a gas engine, converting energy into electricity or heat.
Sarah Ervinda Rudianto, a student from Indonesia, developed a small, individual bioreactor that converts organic waste into biogas with the help of fermentation. To start the process, the waste is mixed with cow dung and water. After two weeks, gas starts to develop which is used to fuel cooking stoves. Cooking using biogas reduces the need to cut down of trees for firewood, thus reducing deforestation and the risk of landslides.
I think this is an awesome idea and deserves some recognition!
