BeeVi uses a vacuum and a small amount of water to send poop from the toilet into an underground tank and bioreactor, prompting its creators to call it a "super water-saving vacuum toilet."

Methane from the faeces is turned into a power source for the appliances in the building, including a gas stove, a hot-water boiler, and a fuel cell that produces electricity. 💡

Students who use the toilet are rewarded with 10 units of digital currency called Ggool per day.
Ggool can be used at a market on campus to buy items like bananas, stationery, and instant cup noodles. 🍜
