As the planet is hastily running short of natural resources, communities are looking to waste as an asset. Anything from biochar to human excrement are now staples in energy production. To bring everything together, engineers have created the NEWgenerator, which processes materials found in sewage.
First, the waste is fed into a bioreactor, where anaerobic microorganisms break down the solids and produce biogas.
The methane produced is chemical-free and perfect for cooking and heating. To complete the cycle, USF engineers have also made the most of liquid and solid waste.
The water that passes through is… disinfected with chlorine, and while the end result is probably still not drinkable, it’s clean enough to use to flush the toilets in the block or irrigate crops.
The remainder of the waste can be used as fertilizer. So far, the system is testing waters in India and South Africa. Each device is usable for up to 100 people a day, with future versions projected to reach thousands. Considering that millions are without access to basic amenities, the NEWgenerator is a game-changer for marginalized communities.
