Digital Assets/ESG: A South Korean University Pays 10 Ggool To Students To Recycle Their Poo
Ggool is a digital currency devised by Cho Jae-weon, an urban and environmental engineering professor at the Ulsan National Institute of Science and Technology (UNIST).
Professor Cho is the inventor of the BeeVi toilet, which routes human excrement to a laboratory that converts it to biogas and manure. The eco-friendly toilet disburses 10 Ggool, a cryptocurrency created by Cho, to every person who uses the toilet for defecation. The biogas (methane) is a power source for the university building while the manure is used in gardening. (New York Post)
At the Ulsan National Institute of Science and Technology (UNIST) in Ulsan, South Korea, human faeces is being used in a virtuous cycle to generate power and manure, while providing the defecators with cryptocurrency to meet some of their daily needs.
“If we think out of the box, feces has precious value to make energy and manure. I have put this value into ecological circulation,” Cho says.

And its no mean sum – an average person sheds about 500 gm of poo a day. When recycled through Cho’s system it generates 50 liters of methane gas – enough to generate 0.5kWh, or to drive a car for nearly 1.2 km. That’s valuable enougn to pay 10 Ggool each time for a person’s waste, and help save on the university’s energy bills.
The Ggool can be used by the students to pay for things like coffee on campus, fruits and books by simply scanning a QR code to pay with the digital coin.
