Talk about reducing your ecological footprint & recycling!
17-year-old high school senior, Leroy Mwasaru, and four of his friends found a way for everything we naturally produce to be converted into biopower. So cool.
The friends are proposing to build a Human Waste Bioreactor [HWB] that collects the waste from all 720 students living in the dorm, organic waste from the kitchens, cow dung, grass clippings, etc. This will help their community by improving water quality, reducing school’s costs, having self-sustainable power sources and respecting their environment.
Grist explains that the HWB is “an underground chamber [which] holds the human, animal, and kitchen excrement, while microorganisms go to work breaking down the muck. The process releases biogas, a source of renewable energy comprised mostly of methane, the same as the fossil fuel natural gas that powers most non-electric stoves in the U.S. The gas is contained in the HWB, ready to use as fuel.”
